General Information
The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect
installation or adjustment of the optional operating parameters of the equipment or from mismatching the variable speed
drive with the motor.
The contents of this guide are believed to be correct at the time of printing. In the interests of a commitment to a policy
of continuous development and improvement, the manufacturer reserves the right to change the specification of the
product or its performance, or the contents of the guide, without notice.
All rights reserved. No parts of this guide may be reproduced or transmitted in any form or by any means, electrical or
mechanical including photocopying, recording or by an information storage or retrieval system, without permission in
writing from the publisher.
Drive software version
This product is supplied with the latest software version. If this drive is to be connected to an existing system or machine,
all drive software versions should be verified to confirm the same functionality as drives of the same model already
present. This may also apply to drives returned from a Control Techniques Service Centre or Repair Centre. If there is
any doubt please contact the supplier of the product.
The software version of the drive can be checked by looking at Pr 11.29 and Pr 11.34. This takes the form of xx.yy.zz
where Pr 11.29 displays xx.yy and Pr 11.34 displays zz. (e.g. for software version 01.01.00, Pr 11.29 = 1.01 and Pr 11.34
displays 0).
Environmental statement
Control Techniques is committed to minimising the environmental impacts of its manufacturing operations and of its
products throughout their life cycle. To this end, we operate an Environmental Management System (EMS) which is
certified to the International Standard ISO 14001. Further information on the EMS, our Environmental Policy and other
relevant information is available on request, or can be found at www.greendrives.com.
The electronic variable-speed drives manufactured by Control Techniques have the potential to save energy and
(through increased machine/process efficiency) reduce raw material consumption and scrap throughout their long
working lifetime. In typical applications, these positive environmental effects far outweigh the negative impacts of product
manufacture and end-of-life disposal.
Nevertheless, when the products eventually reach the end of their useful life, they must not be discarded but should
instead be recycled by a specialist recycler of electronic equipment. Recyclers will find the products easy to dismantle
into their major component parts for efficient recycling. Many parts snap together and can be separated without the use
of tools, while other parts are secured with conventional fasteners. Virtually all parts of the product are suitable for
recycling.
Product packaging is of good quality and can be re-used. Large products are packed in wooden crates, while smaller
products come in strong cardboard cartons which themselves have a high recycled fibre content. If not re-used, these
containers can be recycled. Polythene, used on the protective film and bags for wrapping product, can be recycled in the
same way. Control Techniques' packaging strategy prefers easily-recyclable materials of low environmental impact, and
regular reviews identify opportunities for improvement.
When preparing to recycle or dispose of any product or packaging, please observe local legislation and best practice.
REACH legislation
EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) requires
the supplier of an article to inform the recipient if it contains more than a specified proportion of any substance which is
considered by the European Chemicals Agency (ECHA) to be a Substance of Very High Concern (SVHC) and is
therefore listed by them as a candidate for compulsory authorisation.
For current information on how this requirement applies in relation to specific Control Techniques products, please
approach your usual contact in the first instance. Control Techniques position statement can be viewed at:

1 Parameter structure
The drive parameter structure consists of menus and parameters.
The drive initially powers up so that only menu 0 can be viewed. The up
and down arrow buttons are used to navigate between parameters and
once level 2 access (L2) has been enabled in Pr 0.49, and the left and
right buttons are used to navigate between menus. For further
information, see section 2.7 Parameter access level and security on
page 13.
Figure 1-1 Parameter navigation
* can only be used to move between menus if L2 access has
been enabled (Pr 0.49).
The menus and parameters roll over in both directions; i.e. if the last
parameter is displayed, a further press will cause the display to rollover
and show the first parameter.
When changing between menus the drive remembers which parameter
was last viewed in a particular menu and thus displays that parameter.
Figure 1-2 Menu structure
1.1 Menu 0
Menu 0 has up to 19 fixed parameters and 40 programmable parameters
that are defined in menu 11 and menu 22. Menu 0 parameters are
copies of advanced menu parameters, and although these parameters
are accessible via drive serial comms, they are not accessible to any
Solutions Modules. All menu 0 read/write parameters are saved on
exiting the edit mode. Table 1-1 gives the default structure for each drive
type setting. Where alternative parameters are selected with motor map
2 from menu 21 these are shown below the motor map 1 parameters.

Menu 0 is used to bring together various commonly used parameters for basic easy set up of the drive. All the parameters in menu 0 appear in other
menus in the drive (denoted by {…}).
Menus 11 and 22 can be used to change most of the parameters in menu 0. Menu 0 can also contain up to 59 parameters by setting up menu 22.

1.2 Advanced menus
The advanced menus consist of groups or parameters appropriate to a
specific function or feature of the drive. These are accessible via the
keypad, drive serial comms and Solutions Modules. All advanced menu
parameters are only saved by setting Pr x.00 to 1000 and applying a
reset (except parameters shown as power-down saved which are saved
automatically at power-down). The advanced menus are accessible
when the user selects L2 in Pr 11.44 (Pr 0.49 in menu 0). This can be
done even if security is programmed. Pr 11.44 can be saved in
EEPROM so that either Menu 0 only, or Menu 0 and the advanced
menus are accessible at power-up.
1.3 Solutions Modules
Any Solutions Module type is recognized with all drive types in any slots.
The relevant template is used to define menu 15 for the module type

2 Keypad and display
2.1 Understanding the display
There are two keypads available for the Unidrive SP. The SM-Keypad has an LED display and the SM-Keypad Plus has an LCD display. Both
keypads can be installed to the drive but the SM-Keypad Plus can also be remotely mounted on an enclosure door.
2.1.1 SM-Keypad / SP0-Keypad
The display consists of two horizontal rows of 7 segment LED displays.
The upper display shows the drive status or the current menu and
parameter number being viewed.
The lower display shows the parameter value or the specific trip type.
Figure 2-1 SM-Keypad
2.1.2 SM-Keypad Plus
The display consists of three lines of text.
The top line shows the drive status or the current menu and parameter
number being viewed on the left, and the parameter value or the specific
trip type on the right.
The lower two lines show the parameter name or the help text.
Features :
• Parameter names displayed
• Units displayed (Hz, A, rpm, %)
• Parameter help text
• Diagnostics help text
• 5 language support: (English, French, German, Spanish and Italian)
• Displays SM-Applications virtual parameters: Menus 70 to 91
• Hardware key using the SM-Keypad Plus as a key to modify the
drive set-up
• User defined parameter set
• Browsing filter
• Adjustable contrast
Figure 2-2 SP0 Keypad Figure 2-3 SM-Keypad Plus
The red stop button is also used to reset the drive.
2.2 Keypad operation
2.2.1 Control buttons
The keypad consists of:
1. Joypad - used to navigate the parameter structure and change parameter values.
2. Mode button - used to change between the display modes – parameter view, parameter edit, status.
3. Three control buttons - used to control the drive if keypad mode is selected.
4. Help button (SM-Keypad Plus only) - displays text briefly describing the selected parameter.
The Help button toggles between other display modes and parameter help mode. The up and down functions on the joypad scroll the help text to
allow the whole string to be viewed. The right and left functions on the joypad have no function when help text is being viewed.
The display examples in this section show the SM-Keypad 7 segment LED display. The examples are the same for the SM-Keypad Plus except that
the information displayed on the lower row on the SM-Keypad is displayed on the right hand side of the top row on the SM-Keypad Plus.
The drive parameters are accessed as shown in Figure 2-4.

Figure 2-4 Display modes
2.3 Status mode
In status mode the 1st row shows a four letter mnemonic indicating the
status of the drive. The second row show the parameter last viewed or
edited.
2.4 Parameter view mode
In this mode the 1st row shows the menu.parameter number and the 2nd
row the parameter value. The 2nd row gives a parameter value range of
-999,999 to 9,999,999 with or without decimal points. (32 bit parameters
can have values outside this range if written by an application module. If
the value is outside this range “-------“is shown and the parameter value
cannot be changed from the keypad). The Up and Down keys are used
to select the parameter and the Left and Right keys are used to select
the menu. In this mode the Up and Down keys are used to select the
parameter within the selected menu. Holding the Up key will cause the
parameter number to increment until the top of the menu is reached. A
single Up key action when the last parameter in a menu is being
displayed will cause the parameter number to roll over to Pr x.00.
Similarly holding the Down key will cause the parameter number to
decrement until Pr x.00 is reached and a single Down key action will
cause the parameter number to roll under to the top of the menu.
Pressing the Up and Down keys simultaneously will select Pr x.00 in the
currently selected menu.
The Left and Right keys are used to select the required menu (provided
the security has been unlocked to allow access to menus other than 0).
Holding the Right key will cause the menu number to increment until the
Menu 22 is reached. A single Right key action when Menu 22 is being
displayed will cause the menu number to roll over to 0. Similarly holding
the Left key will cause the menu number to decrement to 0 and a single
key action will cause the menu number to roll under to Menu 22.
Pressing the Left and Right keys simultaneously will select Menu 0.
The drive remembers the parameter last accessed in each menu such
that when a new menu is entered the last parameter viewed in that menu
will re-appear.
2.5 Edit mode
Up and Down keys are used to increase and decrease parameter values
respectively. If the maximum value of a parameter is greater than 9 and it
is not represented by strings, then the Left and Right keys can be used
to select a digit to adjust. The number of digits which can be
independently selected for adjustment depends on the maximum value
of the parameter. Pressing the Right key when the least significant digit
is selected will cause the most significant digit to be selected, and vice-
versa if the Left key is pressed when the most significant digit is
selected. When a digit value is not being changed by the Up or Down
keys the selected digit flashes to indicate which one is currently
selected. For string type parameters the whole string flashes when
adjustment is not occurring because there is no digit selection.
During adjustment of a parameter value with the Up or Down keys the
display does not flash, providing the parameter value is in range, such
that the user can see the value being edited without interruption.
Adjustment of a numerical value can be done in one of two ways; firstly
by using the Up and Down keys only, the selected digit remaining the
least significant digit; and secondly by selecting each digit in turn and
adjusting them to the required value.

Holding the Up or Down key in the first method will cause the
parameters value to change more rapidly the longer the key is held, until
such time that the parameters maximum or minimum is reached.
However with the second method an increasing rate of change does not
take place when adjusting any other digit other than the least significant
digit since a digit can only have one of 10 different values. Holding the
Up or Down will cause an auto repeat and roll over to more significant
digits but the rate of change is unaltered. If the maximum or minimum is
exceeded when adjusting any other digit than the least significant one,
the maximum value will flash on the display to warn the user that the
maximum or minimum has been reached. If the user releases the Up or
Down key before the flashing stops the last in range value will re-appear
on the display. If the Up or Down key is held the display will stop flashing
after three seconds and the maximum value will be written to the
parameter.
Parameters can be set to 0 by pressing the Up and Down keys
simultaneously.
2.6 SM-Keypad Plus
All SM-Keypad Plus displays built after data code N10 have software
version 4.02.00 programmed and support 5 languages (English, French,
German, Spanish and Italian) in addition to a user defined parameter set.
This software also gives the user access to two menus for SM-Keypad
Plus. Menu 40 is for SM-Keypad Plus set up, menu 41 selects commonly
used parameters for quick browsing.
Keypads built prior to N10 only support one user defined extra
parameter set only.
The SM-Keypad Plus contains two menus, menu 40 and menu 41. The
parameters in these menus are listed below.

2.7 Parameter access level and security
The parameter access level determines whether the user has access to
menu 0 only or to all the advanced menus (menus 1 to 22) in addition to
menu 0.
The User Security determines whether the access to the user is read
only or read write.
Both the User Security and Parameter Access Level can operate
independently of each other as shown in the table below:
RW = Read / write access RO = Read only access
The default settings of the drive are Parameter Access Level L1 and
user Security Open, i.e. read / write access to Menu 0 with the advanced
menus not visible.
2.7.1 Access Level
The access level is set in Pr 0.49 and allows or prevents access to the
advanced menu parameters.
2.7.2 Changing the Access Level
The Access Level is determined by the setting of Pr 0.49 as follows:
The Access Level can be changed through the keypad even if the User
Security has been set.
2.7.3 User Security
The User Security, when set, prevents write access to any of the
parameters (other than Pr. 0.49 Access Level) in any menu.
Setting User Security
Enter a value between 1 and 999 in Pr 0.34 and press the button;
the security code has now been set to this value. In order to activate the
security, the Access level must be set to Loc in Pr 0.49. When the drive
is reset, the security code will have been activated and the drive returns
to Access Level L1. The value of Pr 0.34 will return to 0 in order to hide
the security code. At this point, the only parameter that can be changed
by the user is the Access Level Pr 0.49.
Unlocking User Security
Select a read write parameter to be edited and press the button, the
upper display will now show CodE. Use the arrow buttons to set the
security code and press the button.
With the correct security code entered, the display will revert to the
parameter selected in edit mode.
If an incorrect security code is entered the display will revert to
parameter view mode.
To lock the User Security again, set Pr 0.49 to Loc and press the
reset button.
Disabling User Security.
Unlock the previously set security code as detailed above. Set Pr 0.34 to
0 and press the button. The User Security has now been disabled,
and will not have to be unlocked each time the drive is powered up to
allow read / write access to the parameters.

2.8 Alarm and trip display
An alarm can flash alternately with the data displayed on the 2nd row
when one of the following conditions occur. If action is not taken to
eliminate the alarm, except "Auto tune", "Lt" and "PLC", the drive may
eventually trip. Alarms flash once every 640ms except "PLC" which
flashes once every 10s. Alarms are not displayed when a parameter is
being edited.
When a trip occurs the drive switches to status mode and "trip" is shown
on the 1st row and the trip string flashes on the 2nd row. If the trip is a
power module trip and the drive is a multi-module drive, the number of
the power module that initiated the trip flashes alternately with the trip
string. The read only parameters listed below are frozen with any trip
except UV trip until the trip is cleared. For a list of the possible trip strings
see Pr 10.20. Pressing any of the parameter keys changes the mode to
the parameter view mode. If the trip is HF01 to HF16 then no key action
is recognized.
2.9 Keypad control mode
The drive can be controlled from the keypad if Pr 1.14 is set to 4. The
Stop and Run keys automatically become active (the Reverse key may
be optionally enabled with Pr 6.13). The frequency/speed reference is
defined by Pr 1.17. This is a read only parameter that can only be
adjusted in status mode by pressing the Up or Down keys. If keypad
control mode is selected, then pressing the Up or Down keys in status
mode will cause the drive to automatically display the keypad reference
and adjust it in the relevant direction. This can be done whether the drive
is disabled or running. If the Up or Down keys are held the rate of
change of keypad reference increases with time.
The units used for to display the keypad reference for different modes
are given below.
2.10 Drive reset
A drive reset is required to: reset the drive from a trip (except some
“HFxx” trips which cannot be reset); and other functions as defined in
section 3 Parameter x.00 on page 16. A reset can be performed in four
ways:
1. Stop key: If the drive has been set up such that the stop key is not
operative then the key has a drive reset function only. When the stop
function of the stop key is enabled, a reset is initiated while the drive
is running by holding the Run key and then pressing the Stop key.
When the drive is not running the Stop key will always reset the
drive.
2. The drive resets after a 0 to 1 transition of the Drive Reset parameter
(Pr 10.33). A digital input can be programmed to change this
parameter.
3. Serial comms, fieldbus or applications Solutions Module: Drive reset
is triggered by a value of 100 being written to the User trip parameter
(Pr 10.38).
4. Auto reset: Pr 10.34 can be used to provide an auto-reset function.
If the drive trips EEF (internal EEPROM error) then it is not possible to
reset the drive using the normal reset methods described above. 1233 or
1244 must be entered into Pr x.00 before the drive can be reset. Default
parameters are loaded after an EEF trip, and so the parameters should
be reprogrammed as required and saved in EEPROM.
If the drive is reset after a trip from any source other than the Stop key,
the drive restarts immediately, if:
1. A non-latching sequencer is used with the enable active and one of
run forward, run reverse or run active
2. A latching sequencer is used if the enable and not stop are active
and one of run forward, run reverse or run is active.
If the drive is reset with the Stop key the drive does not restart until a not
active to active edge occurs on run forward, run reverse or run.
2.11 Second motor parameters
An alternative set of motor parameters are held in menu 21 which can be
selected by Pr 11.45. When the alternative parameter set is being used
by the drive the decimal point after the right hand digit in the 1st row is
on.

2.12 Special display functions
The following special display functions are used.
1. If the second motor map is being used the decimal point second
from the right of the first row is on.
2. When parameters are saved to a SMARTCARD the right-most
decimal point on the first row flashes for 2 seconds.
During power up one or more of the following actions may be required.
Each action may take several seconds, and so special display strings
are shown.

It may be necessary for a Solutions Module to transfer
parameter information from the drive. This is only carried out
if the parameter information held by the Solutions Module is
for a different drive software version. The drive allows up to
five seconds for this process.

3 Parameter x.00
Parameter x.00 is available in all menus and has the following functions.
*These functions do not require a drive reset to become active. All other
functions require a drive reset.
3.1 Parameter x.00 reset
When an action is started by setting Pr x.00 to one of the above values
and initiating a drive reset this parameter is cleared when the action is
completed successfully. If the action is not started, e.g. because the
drive is enabled and an attempt is made to load defaults, etc., Pr x.00 is
not cleared and no trip is produced. If the action is started and then fails
for some reason a trip is always produced and Pr x.00 is not cleared. It
should be noted that parameter saves etc. can also be initiated with the
copying parameter (Pr 11.42). If actions that can be initiated by either
parameter are started and then completed successfully Pr x.00 is
cleared and Pr 11.42 is cleared if it has a value of less than 3.
It should be noted that there could be some conflict between the actions
of Pr x.00 and Pr 11.42 (Parameter copying) when the drive is reset. If
Pr 11.42 has a value of 1 or 2 and a valid action is required from the
value of Pr x.00 then only the action required by Pr x.00 is performed.
Pr x.00 and Pr 11.42 are then reset to zero. If Pr 11.42 has a value of 3
or 4 it will operate correctly causing parameters to be save to a smart
card each time a parameter save is performed.
3.2 Saving parameters in drive EEPROM
Drive parameters are saved to drive EEPROM by setting Pr x.00 to 1000
or 1001 and initiating a drive reset. In addition to user save parameters,
power down save parameters are also saved by these actions and by
changing drive mode, but not by any other actions that result in
parameters being saved to drive EEPROM (i.e. loading defaults). Power
down save parameters are not saved at power down unless the drive is
supplied from a normal mains supply, and so this gives the user the
option of saving these parameters when required. When the parameter
save is complete Pr x.00 is reset to zero by the drive. Care should be
taken when saving parameters because this action can take between
400ms and several seconds depending on how many changes are
stored in the EEPROM. If the drive is powered down during a parameter
save it is possible that data may be lost. When the drive is operating
from a normal mains supply then it will stay active for a short time after
the power is removed, however, if the drive is being powered from a 24V
control supply, or it is being operated from a low voltage battery supply,
the drive will power down very quickly after the supply is removed. The
drive provides two features to reduce the risk of data loss when the drive
is powered down.
1. If Pr x.00 is set to 1000 a parameter save is only initiated on drive
reset if the drive is supplied from a normal mains supply (Pr 10.16 =
0 and Pr 6.44 = 0). 1001 must be used to initiate a save if the drive is
not supplied from a normal mains supply.
2. Two banks of arrays are provided in EEPROM to store the data.
When a parameter save is initiated the data is stored in a new bank
and only when the data store is complete does the new bank
become active. If the power is removed before the parameter save is
complete a SAVE.Er trip (user save parameter save error) or
PSAVE.Er trip (power down save parameter save error) will be
produced when the drive is powered up again indicating that the
drive has reverted to the data that was saved prior to the last
parameter save.
The second feature will significantly reduce the possibility of completely
invalidating all saved data, which would result in an EEF trip on the next
power-up. However the following points should be noted:
1. If the power is removed during a parameter save the current data
that is being saved to the EEPROM that is different from the last
data saved in the EEPROM will be lost and SAVE.Er or PSAVE.Er
trip will occur on power-up.
2. This feature does not apply when user save parameters are saved
automatically by adjusting the values in menu 0 with an LED keypad.
However, the time taken to save parameters in this way is very short,
and is unlikely to cause data loss if the power is removed after the
parameter has been changed. It should be noted that any parameter
changes made in this way are included in the currently active bank in
the EEPROM, so that if the power is removed during a subsequent
save initiated via Pr x.00 that results in an SAVE.Er trip, the changes
made via menu 0 will be retained and not lost.
3. User save parameters are saved to drive EEPROM after a transfer
of data from an electronic nameplate in an encoder.
4. User save parameters are saved to drive EEPROM after a transfer
of data from a SMART card.
5. This feature is not provided for data saved to a SMART card, and so
it is possible to corrupt the data files on a SMART card if the power is
removed when data is being transferred to the card.
6. User save parameters are saved to drive EEPROM after defaults
are loaded.

7. When the drive mode is changed all data in the EEPROM is deleted
and then restored with the defaults for the new mode. If the power is
removed during a change of drive mode, an EEF trip is likely to
occur on the next power-up. After a change of drive mode the power
down save parameters are also saved. As these parameters are not
saved if the power is removed unless the drive is supplied with a
normal mains supply, this ensures that the power down save
parameters are always stored correctly for the new drive mode. The
first time parameters are saved after the change of drive mode the
save will take slightly longer than a normal parameter save.
8. When a Solutions Module is changed for a different type in a slot, or
a module is inserted when one was not present previously or a
module is removed the EEPROM is forced to re-initialise itself on the
next parameter saves. On the first parameter save one bank is
cleared and then written and on the next parameter save the other
bank is cleared and rewritten. Each of these parameter saves takes
slightly longer than a normal parameter save.
9. The new system has been introduced for user save parameter in
V01.07.00 software, and power down save parameters in V01.08.00
software. When the firmware is updated from an earlier version the
drive will automatically update the EEPROM correctly. If the software
is changed back to an earlier version defaults should be loaded after
the change. If it is subsequently changed back to V01.07.00/
V01.08.00 or later defaults should be loaded after the change.
3.3 Loading defaults
When defaults are loaded the user save parameters are automatically
saved to the drive EEPROM in all modes. Standard defaults are loaded
by setting 1233 in Pr x.00 performing a drive reset.
The following differences from standard defaults are available when
different values are set in Pr x.00.
US Default Differences (Pr x.00 = 1244 and perform a drive reset)
3.4 SMARTCARD transfers
Drive parameters, set-up macros and internal ladder programs can be
transferred to/from SMARTCARDs. See Pr 11.36 to Pr 11.40.
3.5 Electronic nameplate transfers
Some encoders using Stegmann Hiperface or EnDat comms can hold
motor data. The data can be transferred to/from the encoder by writing
110zy to parameter x.00 and resetting the drive where z is 0 for the drive
or 1, 2 or 3 for Solutions Module slots 1, 2 or 3 respectively. See Chapter
8 Electronic nameplate on page 408 for details.
3.6 Display non-default values or
destination parameters
If a value of 12000 is written to Pr x.00, then only parameters that are
different from the last defaults loaded and Pr x.00 are displayed. If a
value of 12001 is written to Pr x.00, then only destination parameters are
displayed. This function is provided to aid locating destination clashes if
a dESt trip occurs.

In the following sections descriptions are given for the advanced parameter set. With each parameter the following information block is given.
The top row gives the menu parameter number and name. The other
rows provide the following information.
Drive modes
The drive modes are the modes in which this parameter is accessible. If
the parameter is not present the parameter is skipped when accessing
from the keypad. The following types are possible.
Open-loop - The control strategy is V/F mode with fixed boost or open-
loop vector control.
Closed-loop vector - The control strategy is rotor flux oriented vector
control with closed-loop current operation for induction motors. The drive
can be operated with or without position feedback.
Servo - The control strategy is rotor flux oriented vector control with
closed-loop current operation for permanent magnet synchronous
motors. The drive must be operated with position feedback.
Regen - The drive operates as a PWM rectifier.
Coding
This guide will show all bit parameters (with the Bit coding), as having a
parameter range of "0 to 1", and a default value of either "0" or "1". This
reflects the value seen through serial communications. The bit
parameters will be displayed on the SM-Keypad or SM-Keypad Plus (if
used) as being "OFF" or "On" ("OFF"= 0, "On" = 1).

4.1 Parameter ranges and variable maximums:
The two values provided define the minimum and maximum values for the given parameter. In some cases the parameter range is variable and
dependant on either:
• other parameters,
• the drive rating,
• drive mode
• or a combination of these.
The values given in Table 4-1 are the variable maximums used in the drive.
Table 4-1 Definition of parameter ranges & variable maximums
Maximum Definition
SPEED_FREQ_MAX
[Open-loop 3000.0Hz,
Closed-loop vector and Servo
40000.0rpm]
Maximum speed (closed-loop mode) reference or frequency (open-loop mode) reference
If Pr 1.08 = 0: SPEED_FREQ_MAX = Pr 1.06
If Pr 1.08 = 1: SPEED_FREQ_MAX is Pr 1.06 or – Pr 1.07 whichever is the largest
(If the second motor map is selected Pr 21.01 is used instead of Pr 1.06 and Pr 21.02 instead of Pr 1.07)
SPEED_LIMIT_MAX
[40000.0rpm]
Maximum applied to speed reference limits
A maximum limit may be applied to the speed reference to prevent the nominal encoder frequency from
exceeding 500kHz (410kHz for software version V01.06.00 and earlier). The maximum is defined by
SPEED_LIMIT_MAX (in rpm) = 500kHz x 60 / ELPR = 3.0x107 / ELPR subject to an absolute maximum of
40,000 rpm. It should be noted that this limit makes no allowance for controller overshoot, and that the
maximum encoder frequency should not exceed 500kHz even under overshoot conditions.
ELPR is equivalent encoder lines per revolution and is the number of lines that would be produced by a
quadrature encoder.
• Quadrature encoder ELPR = number of lines per revolution
• F and D encoder ELPR = number of lines per revolution / 2
• Resolver ELPR = resolution / 4
• SINCOS encoder ELPR = number of sine waves per revolution
• Serial comms encoder ELPR = resolution / 4
This maximum is defined by the device selected with the speed feedback selector (Pr 3.26) and the ELPR set
for the position feedback device. If a resolver is used as speed feedback from a Solutions Module the
calculation is different (see Pr 15/16/17.10 for the SM-Resolver module). With closed-loop vector mode it is
possible to disable this limit via parameter Pr 3.24, so that the drive can be switched between operation with
and without feedback when the speed becomes too high for the feedback device. SPEED_LIMIT_MAX is
defined as above when Pr 3.24 = 0 or 1, and is 40,000rpm when Pr 3.24 = 2 or 3.
SPEED_MAX
[40000.0rpm]
Maximum speed
This maximum is used for some speed related parameters in menu 3. To allow headroom for overshoot etc.
the maximum speed is twice the maximum speed reference.
SPEED_MAX = 2 x SPEED_FREQ_MAX
RATED_CURRENT_MAX
[9999.99A]
Maximum motor rated current or maximum normal duty current rating
RATED_CURRENT_MAX ≤ 1.36 x Kc
The rated current can be increased above the current scaling level (Kc) up to a level not exceeding 1.36 x Kc.
The actual level varies from one drive size to another. (Maximum motor rated current is the maximum normal
duty current rating). Refer to Table 4-2
DRIVE_CURRENT_MAX
[9999.99A]
Maximum drive current
The maximum drive current is the current at the over current trip level and is given by:
DRIVE_CURRENT_MAX = Kc / 0.45
where Kc is the current scaling factor

4.1.3 Update rate
Defines the rate at which the parameter data is written by the drive
(write) or read and acted upon by the drive (read). Where background
update rate is specified, the update time depends on the drive processor
load.
Generally the update time is between 2ms and 30ms, however, the
update time is significantly extended when loading defaults, changing
drive mode, transferring data to/from a SMARTCARD, or transferring
blocks of parameters or communications messages to/from the drive
(not a Solutions Module) via the drive serial comms port.

Some functions have source pointer parameters, i.e. drive outputs, PID
controller etc.. The source pointer parameter range is Pr 0.00 to
Pr 21.51. The source pointer is set up to point to a parameter, which
supplies the information to control the source and this is referred to as
the source data parameter. For example, Pr 7.19 is the source pointer
parameter for analog output 1. If Pr 7.19 is set to a value of 18.11, then
Pr 18.11 is the source data parameter, and as the value of Pr 18.11 is
modified the analog output level is changed.
1. If the parameter number in the source pointer parameter does not
exist the input is taken as zero.
2. If the source is not a bit type source (i.e. not a digital output etc).
then the source level is defined by (source data value x 100%) /
source data parameter maximum. Generally the result is rounded
down to the nearest unit, but other rounding effects may occur
depending on the internal scaling of the particular source function.
3. If the source is a bit, i.e. a digital output, and the source data
parameter is a bit parameter then the input to the source function
follows the value of the source data parameter.
4. If the source is a bit, i.e. a digital output, and the source data
parameter is not a bit parameter the source input is zero if the
source data value is less than source data parameter maximum / 2
rounded down to the nearest unit. The source input is one if the
source data value is greater than or equal to source data parameter
maximum / 2 rounded down to the nearest unit. For example if the
source pointer parameter is set to Pr 18.11, which has a maximum of
32767, the source input is zero if the source data value is less than
16383 and one if it is greater than this.
4.2.2 Destinations
Some functions have destination pointer parameters, i.e. drive inputs,
etc.. The destination pointer parameter range is P 0.00 to Pr 21.51. The
destination pointer parameter is set up to point to a parameter, which
receives information from the function referred to as the destination
parameter.
1. If the parameter number in the destination pointer parameter does
not exist then the output value has no effect.
2. If the destination parameter is protected then the output value has
no effect.
3. If the function output is a bit value (i.e. a digital input) the destination
parameter value does not operate in the same way as a source
described above, but is always either 0 or 1 depending on the state
of the function output whether the destination parameter is a bit
parameter or not.
4. If the function output is not a bit value (i.e. analog input) and the
destination parameter is not a bit parameter, the destination value is
given by (function output x destination parameter maximum) / 100%.
Generally the result is rounded down to the nearest unit, but other
rounding effects may occur depending on the internal scaling of the
particular source function (rounded down to nearest unit). Pr 1.36
and Pr 1.37 are a special case. The scaling shown in the description
of parameter Pr 1.08 is used when any non-bit type quantity is
routed to these parameters.
5. If the function output is not a bit value and the destination parameter
is a bit value, the destination value is 0 if the function output is less
than 50% of its maximum value, otherwise it is 1.
6. If more than one destination selector is routed to the same
destination, the value of the destination parameter is undefined. The
drive checks for this condition where the destinations are defined in
any menu except menus 15 to 17. If a conflict occurs a dESt trip
occurs that cannot be reset until the conflict is resolved.

4.2.3 Sources and destinations
1. Bit and non-bit parameters may be connected to each other as
sources or destinations. The scaling is as described previously.
2. All new source and destination routing only changes to new set-up
locations when the drive is reset.
3. When a destination pointer parameter within the drive or a dumb
Solutions Module (SM-Resolver, SM-Encoder Plus, SM-Encoder
Output Plus, SM-I/O plus) is changed the old destination is written to
zero, unless the destination change is the result of loading defaults
or transferring parameters from a SMARTCARD. When defaults are
loaded the old destination is set to its default value. When
parameters are loaded from a SMARTCARD the old destination
retains its old value unless a SMARTCARD value is written to it.
4.3 Update rates
Update rates are given for every parameter in the header table as shown
below.
Some parameters have an increased update in special circumstances.
4.3.1 Speed reference update rate
The normal update rate for the speed references (via menu 1) is 4ms,
however it is possible to reduce the sample time to 250μs by selecting
the reference from particular sources. The fast update rate is only
possible provided the conditions given below are met. (Note: high speed
updating is not provided for frequency references - i.e. Open-loop
mode).
Analog input references (not including I/O expansion Solutions
Module)
1. The reference must be derived via Pr 1.36 or Pr 1.37
2. The analog inputs must be in voltage mode with zero offset
3. Bipolar mode must be used or unipolar mode with the minimum
speed (Pr 1.07) set to zero
4. No skip bands are enabled, i.e. Pr 1.29, Pr 1.31 and Pr 1.33 must be
zero.
5. The jog and velocity feed-forward references must not be enabled.
Applications and fieldbus Solutions Modules
Pr 91.02 must be used to define the speed reference (this parameter is
only visible from the Solutions Modules). Any value written to Pr 91.02
should be automatically mapped into preset Pr 1.21 by the Solutions
Module.
In fast update mode the references are sampled every 250μs. A sliding
window filter may be applied to analog input 1 (see Pr 7.26) in normal or
high speed updating modes. The default value for this filter is 4ms,
therefore Pr 7.26 must be set to zero to obtain the fastest possible
update rate.
When fast updating is used the scaling is performed by a simple
multiplication. This minimizes software execution time, but also ensures
that there is no loss of resolution from the v to f converter used to
implement analog input 1. Therefore the speed of the motor may be
controlled with infinite resolution from analog input 1 except for
deadband effects around zero reference. The scale factor used for the
multiplication cannot exactly duplicate the scaling for the two stage
conversion (i.e. conversion in menu 7 to a percentage of full scale, and
conversion to 0.1rpm units) used when high speed updating is not in
operation. Therefore the absolute scaling of the analog inputs varies
slightly between normal and high speed updating.
The amount of difference depends on the maximum speed, user scaling
in menu 7, and the analog input 1 the filter time.
The worst case difference for analog input 1 is 0.12% of full scale, and
for analog inputs 2 and 3 the difference is less than 0.12% with a
maximum speed of 50rpm or more. Typical differences (1500rpm
maximum speed, menu 7 scaling of 1.000, analog input 1 filter of 4ms)
are 0.015% for analog input 1 and 0.004% for analog inputs 2 and 3.
4.3.2 Hard speed reference update rate
The normal update rate for the hard speed reference is 4ms, however it
is possible to reduce the sample time to 250μs by selecting the
reference from particular sources. The fast update rate is only possible
provided the conditions given below are met.
Analog inputs (not including I/O expansion Solutions Module)
The analog inputs must be in voltage mode with zero offset
Limitations are the same as for the references via menu 1 described
above.
Applications and fieldbus Solutions Modules
For faster update rate Pr 91.03 must be used (this parameter is only
visible from the Solutions Modules). Any value written to Pr 91.03 is
automatically mapped into the hard speed reference Pr 3.22.
Encoder reference
It is possible to use the drive encoder as the source for the hard speed
reference. To do this the drive encoder reference destination (Pr 3.46)
should be routed to the hard speed reference parameter. If, and only if,
the maximum drive encoder reference (Pr 3.43) is set to the same value
as the maximum reference value (SPEED_FREQ_MAX), and the
scaling (Pr 3.44) is 1.000, the drive takes the encoder pulses directly.
This gives a form of reference slaving where the integral term in the
speed controller accumulates all pulses from the reference and tries to
match them to the feedback from the motor encoder. Pulses are lost if
the reference reaches a minimum or maximum limit including zero speed
in unipolar mode. The reference is sampled every 250μs. It is possible to
apply scaling even in this high speed update mode by changing the
number of encoder lines per revolution. It is also possible to use this high
speed update mode with some position feedback category Solutions
Modules (see description for the appropriate Solutions Module).

4.3.3 Torque reference update rate
The normal update rate for the torque reference (Pr 4.08) is 4ms,
however it is possible to reduce the sample time to 250μs by selecting
the reference from particular sources, but only in closed-loop vector or
servo modes. The fast update rate is only possible provided the
conditions given below are met.
Analog inputs 2 or 3 on the drive
The analog inputs must be in voltage mode with zero offset.

Analog input scaling
The following diagrams show the scaling applied when analog inputs are used to define the reference and are routed via Pr 1.36 or Pr 1.37.
Reference limits
With reference to the block diagram for Menu 1 (Figure 5-1 on page 30) the following table shows the limits applied to the reference by various blocks
in the reference system. It should be noted that the minimum limit in the main reference limits block changes when either the jog reference or velocity
feedforward references are active. When one of these is active: if Pr 1.08 = 0 the minimum = -Pr 1.06 [-Pr 21.01 for motor map2], if Pr 1.08 = 1 the
minimum = -Pr 1.07 [-Pr 21.02 for motor map 2].
When this parameter is 0 the reference is given by
Pr 1.01 = selected reference x (100 + Pr 1.38) / 100
and when this parameter is 1 the reference is given by
Pr 1.01 = selected reference + Pr 1.04

These parameters are controlled by the drive sequencer as defined in Menu 6. They select the appropriate reference as commanded by the drive
logic. Pr 1.11 will be active if a run command is given, the drive is enabled and the drive is ok. This parameter can be used as an interlock in a
Onboard PLC or SM-Applications program to show that the drive is able to respond to a speed or torque demand.
Pr 1.14 defines how the value of Pr 1.49 is derived as follows:
*Pr 1.41 to Pr 1.44 can be controlled by digital inputs to force the value of Pr 1.49:
all bits equal to zero gives 1,
Pr 1.41 = 1 then Pr 1.49 = 2
Pr 1.42 = 1 then Pr 1.49 = 3
Pr 1.43 = 1 then Pr 1.49 = 4
Pr 1.44 = 1 then Pr 1.49 = 5
The bit parameters with lower numbers have priority over those with higher numbers.

The drive can be controlled from the keypad if Pr 1.14 is set to 4. The Stop and Run keys automatically become active (the Reverse key may be
optionally enabled with Pr 6.13). The frequency/speed reference is defined by Pr 1.17. This is a read only parameter that can only be adjusted in
status mode by pressing the Up or Down keys. If keypad control mode is selected, then pressing the Up or Down keys in status mode will cause the
drive to automatically display the keypad reference and adjust it in the relevant direction. This can be done whether the drive is disabled or running. If
the Up or Down keys are held the rate of change of keypad reference increases with time. The units used for to display the keypad reference for
different modes are given below.
See also Pr 1.51 on page 41 (Power-up keypad control mode reference).
See below.
Open loop
The frequency reference resolution is restricted to 0.1Hz from normal parameters, but the resolution can be improved by using the precision
reference. Pr 1.18 defines the coarse part of reference (either positive or negative) with a resolution of 0.1Hz and Pr 1.19 defines the fine part of the
reference (always positive) with a resolution of 0.001Hz. The final reference is given by Pr 1.18 + Pr 1.19. Therefore Pr 1.19 increases positive
references away from zero, and decreases negative references towards zero.
Closed loop
As with open-loop a higher resolution speed reference can be programmed by selecting these parameters. In this case the speed will have a
resolution of 0.001 rpm.

When this bit is at 0 the precision reference parameters are read and stored in internal memory. Because the precision reference has to be set in two
parameters, this bit is provided to prevent the drive reading the parameters while the reference is being updated. Instead, the drive uses the value
stored in memory preventing the possibility of data skew.

Three skip references are available to prevent continuous operation at a speed that would cause mechanical resonance. When a skip reference
parameter is set to 0 that filter is disabled. The skip reference band parameters define the frequency or speed range either side of the programmed
skip reference, over which references are rejected. The actual reject band is therefore twice that programmed in these parameters, the skip reference
parameters defining the centre of the band. When the selected reference is within a band the lower limit of the band is passed through to the ramps
such that reference is always less than demanded.
This parameter indicates that the selected reference is within one of the skip reference zones such that the motor speed is not as demanded.
Although most parameters can be controlled from analog inputs, these two parameters are a special case in that if an analog input is directed to one
of these parameters, the scan rate of that analog input is increased to 250μs as long as:
1. The reference must be derived via Pr 1.36 or Pr 1.37
2. The analog inputs must be in voltage mode with zero offset
3. Bipolar mode must be used or unipolar mode with the minimum speed (Pr 1.07) set to zero
4. No skip bands are enabled, i.e. Pr 1.29, Pr 1.31 and Pr 1.33 must be zero.
5. The jog and velocity feed-forward references must not be enabled.
These are special parameters when a non-bit type quantity uses these parameters as a destination (not just from analog inputs). The scaling and
limiting applied is as described with Pr 1.08 on page 33.

This parameter indicates the velocity feed forward reference when position control is used (see section 5.15 Menu 13: Position control on page 232).
This bit indicates that the position controller has selected the velocity feed forward as a reference for the drive
Pr 1.41 to Pr 1.44 control Pr 1.49. The priority order is Pr 1.44 (highest), Pr 1.43, Pr 1.42, Pr 1.41 (lowest). If more than one parameter is active, the
highest priority takes precedence.
Pr 1.41 = 1 forces Pr 1.49 = 2 (see table in Pr 1.14 on page 35 and Pr 1.15 on page 36)
Pr 1.42 = 1 forces Pr 1.49 = 3 (always selects preset references)
Pr 1.43 = 1 forces Pr 1.49 = 4 (always selects keypad control mode)
Pr 1.44 = 1 forces Pr 1.49 = 5 (always selects precision reference)
Pr 1.45 to Pr 1.47 control Pr 1.50.
Pr 1.45 controls Pr 1.50 bit 0*
*See the description with Pr 1.14 and Pr 1.15 on page 36 for more information.
When this flag is set the preset timer for auto preset timer mode (Pr 01.15 = 9) is reset and preset 1 is selected. This can be used to start a new
sequence of reference selection by a programmable input terminal or function. When this bit is zero the preset selection will follow the timer even
when the drive is disabled.

5.4 Menu 2: Ramps
The pre-ramp frequency or speed reference passes through the ramp block controlled by menu 2 before being used by the drive to produce the basic
output frequency (Open-loop modes), or as an input to the speed controller (Closed-loop vector or Servo modes). The ramp block includes: linear
ramps, an S ramp function for ramped acceleration and deceleration, deceleration ramp control to prevent rises in the DC bus voltage within the drive
that would cause an over-voltage trip if no braking resistor is installed.

If this bit is set the ramp will be held. If S ramp is enabled the acceleration will ramp towards zero causing the ramp output to curve towards a constant
speed. If a drive stop is demanded the ramp hold function is disabled.
This parameter does not affect the acceleration ramp, and the ramp output always rises at the programmed acceleration rate subject to the current
limits. It is possible in under some unusual circumstances in open-loop mode (i.e. highly inductive supply) for the motor to reach a low speed in
standard ramp mode, but not completely stop. It is also possible if the drive attempts to stop the motor with an overhauling load in any mode that the
motor will not stop when standard ramp mode or fast ramp mode is used. If the drive is in the deceleration state the rate of fall of the frequency or
speed is monitored. If this does not fall for 10 seconds the drive forces the frequency or the speed reference to zero. This only applies when the drive
is in the deceleration state and not when the reference is simply set to zero. If the speed or frequency reference is just set to zero with an overhauling
or very high inertia load, then the drive may not decelerate.
0: Fast ramp
Fast ramp is used where the deceleration follows the programmed deceleration rate subject to current limits.
1: Standard ramp
Standard ramp is used during deceleration if the voltage rises to the standard ramp level (Pr 2.08). It causes a controller to operate, the output of
which changes the demanded load current in the motor. As the controller regulates the DC bus voltage, the motor deceleration increases as the
speed approaches zero speed. When the motor deceleration rate reaches the programmed deceleration rate the controller ceases to operate and the
drive continues to decelerate at the programmed rate. If the standard ramp voltage (Pr 2.08) is set lower than the nominal DC bus level the drive will
not decelerate the motor, but it will coast to rest. The output of the ramp controller (when active) is a current demand that is fed to the frequency
changing current controller (Open-loop mode) or the torque producing current controller (Closed-loop vector or Servo modes). The gain of these
controllers can be modified with Pr 4.13 and Pr 4.14.

2: Standard ramp with motor voltage boost
This mode is the same as normal standard ramp mode except that the motor voltage is boosted by 20%. This increases the losses in the motor giving
faster deceleration.
Setting this parameter enables the S ramp function. S ramp is disabled during deceleration when the standard ramp voltage controller is active. When
the motor is accelerated again after decelerating in standard ramp the acceleration ramp used by the S ramp function is reset to zero.
This parameter defines the maximum rate of change of acceleration/deceleration. If the S ramp is disabled (Pr 2.06 = 0) a linear ramp is used and the
time in seconds taken for the ramp output to change by frequency ( Δ f*) or speed (Δ w*) is given by:
Frequency (Open-loop mode)
TRamp = Δf* x A / 100
where A is the selected ramp rate in s / 100Hz
Speed (Closed-loop vector and servo)
TRamp = Δw* x A / 1000
Where A is the selected ramp rate in s / 1000rpm
If the S ramp is enabled (Pr 2.06 = 1) then the ramp time is extended as shown in the diagram below.

The time taken in seconds for the ramp output to change by frequency (Δf*) or speed (Δw*) is given below. Two cases are given because the total
ramp time must be calculated with a different equation depending on whether the acceleration is able to reach the selected ramp rate (A) or not. If the
required change is small the selected ramp rate is not reached and the ramp does not include the central linear ramp region. If the required change is
larger the ramp does include the central linear region as shown in the diagram above.
Frequency (Open-loop mode)
Δf*linear = 100 x J / A2
where:
A is the selected ramp rate in s / 100Hz
J is parameter Pr 2.07, the S ramp acceleration limit in s2
/ 100Hz
If the required change is less than Δf*linear then TRamp1 should be used, but if the speed change is greater or equal to Δf*linear TRamp2 should be used.
TRamp1 = 2 √ (Δf* x J / 100)
TRamp2 = (Δf* x A / 100) + (J / A)
Speed (Closed-loop vector and servo)
Δw*linear = 1000 x J / A2
where:
A is the selected ramp rate in s / 1000rpm
J is Pr 2.07, the S ramp acceleration limit in s2
/ 1000rpm
If the required change is less than Δw*linear then TRamp1 should be used, but if the speed change is greater or equal to Δw*linear TRamp1 should be
used.
TRamp1 = 2 √ (Δw* x J / 1000)
TRamp2 = (Δw* x A / 1000) + (J / A)
The default values for the ramp rate and S ramp acceleration limit have been chosen such that for the default maximum speed, the curved parts of the
S ramp are 25% of the original ramp if S ramp is enabled. Therefore the ramp time is increased by a factor of 1.5.
This voltage is used as the control level for standard ramp mode. If this parameter is set too low the machine will coast to rest, and if it is set too high
and no braking resistor is used the drive may give an OU trip. The minimum level should be greater than the voltage produced on the DC bus by the
highest supply voltage. Normally the DC bus voltage will be approximately the rms supply line voltage x √2.

Deceleration failure detection is provided to force the drive to change from the decelerating state to the appropriate stop state if the motor frequency
or speed is held at a constant level for 10s or more when the standard ramp voltage controller is active. When the drive is connected to a highly
inductive supply it is possible for the d.c. link voltage to rise as the motor frequency/speed falls. This rise in d.c. link voltage causes the standard ramp
d.c. link voltage controller to prevent any further deceleration.
In some applications with very high inertia, the motor frequency/speed must fall very slowly or else the power fed into the d.c. link will cause an over-
voltage trip. In these applications it may be necessary to disable the deceleration failure detection system by setting this parameter to 1.
The acceleration rate is selected as follows.
0 Ramp rate selection by terminal input
1 - 8 Ramp rate defined by parameter number, i.e. 1 = Pr 2.11, 2 = Pr 2.12, etc.
9 Ramp rate selection by Pr 1.50
When Pr 2.10 is set to 0 the acceleration ramp rate selected depends on the state of bit Pr 2.32 to Pr 2.34. These bits are for control by digital inputs
such that ramp rates can be selected by external control. The ramp rate selected depends on the binary code generated by these bits as follows:
When Pr 2.10 is set to 9 the appropriate acceleration rate is automatically selected depending on the value of Pr 1.50, and so an acceleration rate can
be programmed to operate with each reference. Since the new ramp rate is selected with the new reference, the acceleration applies towards the
selected preset if the motor needs to accelerate to reach the preset.

When Pr 2.20 is set to 0 the deceleration ramp rate selected depends on the state of bit Pr 2.35 to Pr 2.37. These bits are for control by digital inputs
such that ramp rates can be selected by external control. The ramp rate selected depends on the binary code generated by these bits as follows:
When Pr 2.20 is set to 9 the appropriate deceleration rate is automatically selected depending on the value of Pr 1.50, and so a deceleration rate can
be programmed to operate with each reference. Since the new ramp rate is selected with the new reference, the deceleration applies towards the
selected preset if the motor needs to decelerate to reach the preset.
If an deceleration rate is selected where the parameter is set to 0.000 the deceleration ramp is disabled and the reference changes instantly to its new

Open-loop
If either an acceleration or deceleration rate is selected where the parameter is set to 0.0 in open-loop mode, the ramps are disabled (for both

The jog deceleration rate is only used when the drive is changing speed because the jog reference has changed or to stop from the jog reference. It
is not used to go from the jog to the run state. This prevents the fast ramps normally used with jog from being used when changing between running
and jogging.

These bits are provided for control by logic input terminals for external ramp selection (see Pr 2.10 and Pr 2.20).
The motor and load inertia (Pr 3.18), motor torque per amp (Pr 5.32) and the rate of change of the ramp output (Pr 2.01) are used to produce a torque
feed forward value that should accelerate or decelerate the load at the required rate. This value can be used as a feed forward term that is added to
the speed controller output if Pr 4.22 is set to one. Pr 2.38 shows the torque value as a percentage of rated active current.

5.5 Menu 3: Slave frequency, speed feedback, speed control and regen operation
Menu 3 relates to different functions depending on the drive mode selected as shown in the table below. The menus for some drive modes are
significantly different and therefore the complete menu is covered in different sections. Open-loop is different from Closed-loop vector and Servo
except that it shares a common block of parameters for the drive encoder. The drive encoder parameters are only described in the Closed-loop vector
and Servo section.
Frequency/Speed accuracy and resolution
Digital reference resolution
When a preset frequency/speed is used the reference resolution is 0.1Hz or 0.1rpm. Improved resolution can be obtained by using the precision
reference (0.001Hz or 0.001rpm).
Analog reference resolution
In Open-loop modes the frequency reference controlled by an analog input has a maximum resolution of 12bits plus sign, but this is reduced if the
window filter time for this input controller by Pr 7.26 is reduced below the default value of 4.0ms. The resolution of the frequency reference from
analog inputs 2 or 3 is 10bits plus sign.
In Closed-loop vector or Servo mode the resolution from analog input 1 is better than 16bits plus sign provided the speed reference is routed via
Pr 1.36, Pr 1.37 or Pr 3.22 in high speed update mode. The resolution from analog inputs 2 or 3 is 10bits plus sign.
Accuracy
The absolute frequency and speed accuracy depends on the accuracy of the crystal used with the drive microprocessor. The accuracy of the crystal
is 100ppm, and so the absolute frequency/speed accuracy is 100ppm (0.01%) of the reference, when a preset speed is used. If an analog input is
used the absolute accuracy is further limited by the absolute accuracy and non-linearity of the analog input.

Open-loop
The slave frequency demand is only relevant if the drive is operating in frequency slaving mode, in other modes this parameter reads as 0.0. The
value shown in slaving mode is the fundamental drive output frequency. Frequency slaving mode is used to lock the fundamental frequency produced
by the drive with an external frequency applied to the main drive encoder input. This could be used for example to keep the shafts of two synchronous
machines in lock, by feeding the frequency slaving output from the master drive into the encoder input of the slave drive. Alternatively the two
machines could be operated so that the shafts rotate with an exact ratio, i.e. as though the shafts were connected by gears (see Pr 3.14 and Pr 3.15
on page 54).
The source for frequency slaving mode may be quadrature A/B encoder signals or Frequency and Direction. With the latter care must be taken to
ensure that the D set-up time (10μs) is observed or pulses may be lost. The frequency slaving input must be selected as F and D or quadrature to
match the source mode. The input mode is selected by Pr 3.38 which defines the encoder type. The default for source and destination drives is
quadrature A/B mode, unlike previous products which used F and D only.
The drive will not count pulses while it is disabled (this parameter will show 0.0), but will maintain lock once enabled even if the direction of rotation
reverses. In frequency slaving mode the drive current limits are not active, however, the drive peak limit is active and will try and limit the drive current
to the magnitude limit by modifying the output voltage away from the defined V to F (Voltage to Frequency) characteristic. If synchronous machines
are used and the current required exceeds the drive magnitude limit the slave machine will pole slip.
If the post ramp reference (Pr 2.01) is at or below the level defined by this parameter in either direction the Zero speed flag (Pr 10.03) is 1, otherwise
the flag is 0.

"At speed" flag (Pr 10.06) is set if the post-ramp reference (Pr 2.01) is on the boundaries or within the at speed window. Flags Pr 10.07 and Pr 10.05
are set if the reference is above or below the window respectively.
If Pr 3.09 = 0 reference window mode is used and the "at speed" condition is true if
(|Pr 1.03| - Pr 3.06) ≤ |Pr 2.01| ≤ (|Pr 1.03| + Pr 3.07)
(If the lower limit is less than zero then zero is used as the lower limit).
If Pr 3.09 = 1 absolute window mode is used and the "at speed" condition is true if
Pr 3.06 ≤ |Pr 2.01| ≤ Pr 3.07
The speed detector system also includes an overspeed trip in open-loop mode. The level cannot be set by the user, but the drive produces an
overspeed trip if the final frequency (Pr 5.01) exceeds 1.2 x SPEED_FREQ_MAX.
Frequency slaving as described in Pr 3.01 is enabled by this parameter. Frequency slaving can be enabled or disabled even when the drive is
enabled. The change from slaving to normal operation will result in the frequency ramping from the slaving frequency to the demanded frequency
using whichever ramp rate that is applicable to normal operation. The change from normal operation to slaving will result in an instantaneous change
to the slaving frequency. Therefore the slaving frequency should be similar to the demanded frequency before the change is made.
The slave frequency input can be scaled before it defines the slave frequency demand (Pr 3.01) using Pr 3.14 and Pr 3.15. The numerator and
denominator can be adjusted while the drive is running without causing jumps in angle. However if the change in ratio causes a large change in
frequency the transient current could activate the peak limit or trip the drive. Although Pr 3.15 can be set to zero the drive uses a value of 0.001 if this
parameter is zero.

The frequency slaving output is in the form of F and D or quadrature A/B signals (Pr 3.18 = 0 gives quadrature, Pr 3.18 = 1 gives F and D). When F
and D is used the output frequency is either 1 or 2048 times the drive fundamental output frequency (selected by Pr 3.17). When quadrature A/B
signals are used, the slaving output frequency is effectively divided by 2 giving either 0.5 or 1024 times the drive fundamental output frequency. When
the drive output frequency changes direction there is always a period of 250μs where no pulses are produced. This ensures that with an F and D
output there is a set-up time of 250μs for the direction signal before an edge occurs on the frequency signal. The frequency slaving output operates
up to 1000Hz, above this frequency the outputs could be undefined.

This is the final speed demand at the input to the speed regulator formed by the sum of the ramp output and the hard speed reference (if the hard
speed reference is enabled). If the drive is disabled this parameter will show 0.0.
The speed feedback can be taken from the drive encoder port or a position feedback module installed in any slot as selected with Pr 3.26. Pr 3.02
shows the level of the speed feedback selected for the speed controller. The FI attribute is set for this parameter, so display filtering is active when this
parameter is viewed with one of the drive keypads. The value held in the drive parameter (accessible via comms or a Solutions Module) does not
include this filter, but is a value that is obtained over a sliding 16ms period to limit the ripple seen in this parameter value. The speed feedback value
includes encoder quantization ripple given by the following equation:
Ripple in Pr 3.02 = 60 / 16ms / (ELPR x 4)
where ELPR is the equivalent encoder lines per revolution as defined below.
For example a 4096 line Ab type encoder gives a ripple level of 0.23rpm.
The 16ms sliding window filter is always applied to the value shown in Pr 3.02, but this sliding window filter is not normally applied to the actual speed
feedback used by the speed controller or the drive encoder reference system (Pr 3.43 to Pr 3.46).The user may apply a filter to the speed controller
input and the drive encoder reference system input if required by setting Pr 3.42 to the required filter time. The encoder ripple seen by the speed
controller is given by:
Encoder speed ripple = 60 / Filter time / (ELPR x 4)
If Pr 3.42 is set to zero (no filter) the ripple seen by the speed controller and drive encoder reference system is given by:
Encoder speed ripple = 60 / 250μs / (ELPR x 4)
The diagram above shows the filter arrangement. It should be noted that the same filtering is provided at the speed controller input and for Pr 3.02
when the feedback is obtained from a Solutions Module, but the variable length window filter is controlled by Pr x.19.
It is not advisable to use the speed feedback filter unless it is specifically required for high inertia applications with high controller gains, or if a
commutation signal only encoder is used, because the filter has a non-linear transfer function. It is preferable to use the current demand filters (see Pr
4.12 or 4.23) as these are linear first order filters that provide filtering on noise generated from both the speed reference and the speed feedback. It
should be noted that any filtering included within the speed controller feedback loop, either on the speed feedback or the current demand, introduces
a delay and limits the maximum bandwidth of the controller for stable operation.
The speed ripple can be quite high, for example with a 4096 line encoder the speed ripple is 14.6rpm, but this does not define the resolution of the
speed feedback which is normally much better and depends on the length of the measuring period used to obtain the feedback. This is shown in the
improved resolution of the value accessible in Pr 3.02 which is measured over 16ms, i.e. a resolution of 0.23rpm with a 4096 line encoder. The speed
controller itself accumulates all pulses from the encoder, and so the speed controller resolution is not limited by the feedback, but by the resolution of
the speed reference. If a SINCOS encoder is used the encoder speed ripple is reduced by a factor of 2 ( 2 - INTERPOLATION BITS)
For example with the
nominal 10 bits of interpolation information, the speed ripple is reduced by a factor of 256. This shows how a SINCOS encoder can reduce noise
caused by encoder quantization without any filtering in the speed feedback or the current demand, so that high gains may be used to give high
dynamic performance and a very stiff system.

The speed error is the difference between the final speed demand and the speed feedback in rpm. This does not include the effect of the D term in the
speed controller feedback branch.
The output of the speed regulator is a torque demand given as a percentage of rated motor torque. This is then modified to account for changes in
motor flux if field weakening is active, and then used as the torque producing current reference.
If the speed feedback (Pr 3.02) is at or below the level defined by this parameter in either direction the Zero speed flag (Pr 10.03) is 1, otherwise the
flag is 0.
"At speed" flag (Pr 10.06) is set if the speed feedback (Pr 3.02) is on the boundaries or within the at speed window. Flags Pr 10.07 and Pr 10.05 are
set if the reference is above or below the window respectively.
If Pr 3.09 = 0 reference window mode is used and the "at speed" condition is true if
(|Pr 1.03| - Pr 3.06) ≤ |Pr 3.02| ≤ (|Pr 1.03| + Pr 3.07)

If the speed feedback (Pr 3.02) exceeds this level in either direction an overspeed trip is produced. If this parameter is set to zero the overspeed
threshold is automatically set to 1.2 x SPEED_FREQ_MAX.
In servo mode the motor speed and the motor voltage can be monitored to detect that the motor is accelerating in an uncontrolled way because the
motor phasing angle has not been set up correctly in Pr 3.25 (Pr 21.20 if motor map 2 is selected). If the overspeed threshold is set to zero phasing
angle error monitoring is enabled. If the overspeed threshold is set to any other value this feature is disabled.

The following diagram shows a generalised representation of the speed controller. The controller includes proportional (Kp) and integral (Ki) feed-
forward terms, and a differential (Kd) feedback term. The drive holds two sets of these gains and either set may be selected for use by the speed
controller with Pr 3.16. If Pr 3.16 = 0, gains Kp1, Ki1 and Kd1 are used, if Pr 3.16 = 1, gains Kp2, Ki2 and Kd2 are used. Pr 3.16 may be changed
when the drive is enabled or disabled.
Proportional gain (Kp)
If Kp has a value and Ki is set to zero the controller will only have a proportional term, and there must be a speed error to produce a torque reference.
Therefore as the motor load increases there will be a difference between the reference and actual speeds. This effect, called regulation, depends on
the level of the proportional gain, the higher the gain the smaller the speed error for a given load. If the proportional gain is too high either the acoustic
noise produced by speed feedback quantisation (using digital encoders, resolvers, etc). becomes unacceptable, or the closed-loop stability limit is
reached (using SINCOS encoders).
Integral gain (Ki)
The integral gain is provided to prevent speed regulation. The error is accumulated over a period of time and used to produce the necessary torque
demand without any speed error. Increasing the integral gain reduces the time taken for the speed to reach the correct level and increases the
stiffness of the system, i.e. it reduces the positional displacement produced by applying a load torque to the motor. Unfortunately increasing the
integral gain also reduces the system damping giving overshoot after a transient. For a given integral gain the damping can be improved by
increasing the proportional gain. A compromise must be reached where the system response, stiffness and damping are all adequate for the
application. The integral term is implemented in the form of ∑(Ki x error), and so the integral gain can be changed when the controller is active without
causing large torque demand transients.
Differential gain (Kd)
The differential gain is provided in the feedback of the speed controller to give additional damping. The differential term is implemented in a way that
does not introduce excessive noise normally associated with this type of function. Increasing the differential term reduces the overshoot produced by
under-damping, however, for most applications the proportional and integral gains alone are sufficient. It should be noted that the differential term is
limited internally so that it is ineffective if speed in rpm x Kd x Ki is greater than 170.

To analyze the performance of the speed controller it may be represented as an s-domain model as shown below.
Where:
Kc is the conversion between the speed controller output and the torque producing current. A value of unity at the output of the speed controller gives
a torque producing current equal to Kc. The drive automatically compensates the torque producing current for flux variations in field weakening, and
so Kc can be assumed to have a constant value even in field weakening. See menu 4 for the value of Kc each drive size).
Kt is the torque constant of the motor (i.e. torque in Nm per amp of torque producing current). This value is normally available for a servo motor from
the manufacturer, however for induction motors the value must be calculated from
Kt = Motor rated torque / Motor rated torque producing current
= Motor rated torque / √(Motor rated current2
- No load current2
)
L(s) is the transfer function of the load.
The s-domain system above may be used to determine the performance of systems with a relatively low bandwidth. However, the real drive system
also includes non-ideal delays due to the torque controller response, and speed measurement and control delays. These delays, which can be
approximated with a simple unity gain transport delay (Tdelay) as shown below, should be taken into account for more accurate results.
The speed controller gains used in previous Unidrive products were in internal drive units. Conversion between the previous internal units and the SI
units used in this product are given in the table below.
The user may enter the required speed controller gains into Pr 3.10 to Pr 3.15. However, if the load is predominantly a constant inertia and constant
torque, the drive can calculate the required Kp and Ki gains, provided a value of motor plus load inertia (Pr 3.18) and the motor torque per amp
(Pr 5.32) are set-up correctly. The gain values are calculated to give a required compliance angle or bandwidth. The calculated values for Kp and Ki
are written to Pr 3.10 and Pr 3.11 once per second when one of these set-up methods is selected (i.e. Pr 3.17 = 1 or 2). The values are calculated
from a linear model assuming a pure inertia load, not including unwanted delays in the speed and current controllers. The Kd gain is not affected. If
Pr 3.17 is set to 3 automatic gain set up is not active, but Kp is boosted by a factor of 16.

0: user set-up
With the default value the user should enter the required speed controller gains.
1: Bandwidth set-up
If bandwidth based set-up is required the following parameters must be set correctly: Pr 3.20 = required bandwidth, Pr 3.21 = required damping factor,
Pr 3.18 = motor + load inertia (it is possible to measure the load inertia as part of the auto-tuning process, see Pr 5.12 on page 117), Pr 5.32 = motor
torque per amp.
Ki = J / (Kc x Kt) x (2π x Bandwidth / Kbw)2
= Pr 3.18 / (Kc x Pr 5.32) x (2π x Pr 3.20 / Kbw)2
Where: Kbw = √[ (2ξ2
+ 1) +√((2ξ2
+ 1)2
+ 1) ]
Kp = 2 ξ √ [(Ki x J) / (Kc x Kt)] = 2 ξ √ [(Pr 3.11 x Pr 3.18) / (Kc x Pr 5.32)]
2: Compliance angle set-up
If compliance angle based set-up is required the following parameters must be set correctly: Pr 3.19 = required compliance angle, Pr 3.21 = required
damping factor, Pr 3.18 = motor + load inertia (it is possible to measure the load inertia as part of the auto-tuning process, see Pr 5.12 on page 117),
Pr 5.32 = motor torque per amp.
Ki = 1 / Compliance angle (rad s-1)
Kp = 2 ξ √ [(Ki x J) / (Kc x Kt)] = 2 ξ √ [(Pr 3.11 x Pr 3.18) / (Kc x Pr 5.32)]
3: Kp gain times 16
If this parameter is set to 3 the Kp gain (from whichever source) is multiplied by 16. This is intended to boost the range of Kp for applications with very
high inertia. It should be noted that if high values of Kp are used it is likely that the speed controller output will need to be filtered (see Pr 4.12) or the
speed feedback will need to be filtered (see Pr 3.42). If the feedback is not filtered it is possible the output of the speed controller will be a square
wave that changes between the current limits causing the integral term saturation system to malfunction.
The motor and load inertia represents the total inertia driven by the motor. This is used to set the speed controller gains (see Pr 3.13 on page 60) and
to provide torque feed-forwards during acceleration when required. (see Pr 4.11 on page 100) (It is possible to measure the inertia as part of the auto-
tune process, see Pr 5.12 on page 117.
The compliance angle is the required angular displacement when the drive delivers a torque producing current equivalent to the current scaling (Kc)
with no field weakening.
The bandwidth is defined as the theoretical 3dB point on the closed-loop gain characteristic of the speed controller as a second order system. At this
point the phase shift is approximately 60°. This parameter is used to define the bandwidth used for setting up the speed loop gain parameters
automatically when Pr 3.17 = 1.

This is the damping factor related to the response of the system to a torque transient, and so if the damping factor is unity the response to a load
torque transient is critically damped. The step response of the speed controller gives approximately 10% overshoot with unity damping factor.
This parameter is used to define the damping factor used for setting up the speed loop gain parameters automatically when Pr 3.17 = 1 or 2.
. 0
The hard speed reference is a reference value which does not pass through the ramp system (Menu 2). It is added to the normal post ramp speed
reference. Its value may be written from the keypad, via serial comms, from an analog input or from an encoder input. This parameter can also be
used by the position controller (Menu 13) as the speed reference input. The hard speed reference is selected when Pr 3.23 = 1.
0: Closed-loop vector mode with position feedback
The drive uses the closed-loop vector algorithm with the selected position feedback.
1: RFC mode - Closed-loop vector mode without position feedback
The drive uses the closed-loop vector algorithm and derives the position feedback internally.
2: Closed-loop vector mode with no maximum speed limit
3: RFC mode - Closed-loop vector mode without position feedback with no maximum speed limit
In some applications using closed-loop vector control the maximum speed of the system is above the speed at which the encoder feedback frequency
is too high to be used by the drive. For these type of applications Pr 3.24 should be set to 2 for low speed operation and 3 for high speed operation. It
should be noted that the drive no longer checks that the maximum encoder frequency cannot be exceeded in closed-loop vector control, and so the
user must ensure that Pr 3.24 is set to 3 before the encoder frequency limit is reached.
If the drive encoder lines per rev (Pr 3.34) is set to a value that is not a power of 2 and the drive encoder type (Pr 3.38) is used to select any type of
SINCOS encoder this parameter is forced to zero. This is because the extra processing time required to support the feedback device would not allow
enough time for the closed-loop vector algorithm without position feedback to be executed. It should be noted that if the algorithm without position
feedback is active that the sample rate for 6 and 12kHz operation is reduced from 12kHz to 6kHz. Also operation at 4kHz, 8kHz or 16kHz is not
possible and if these frequencies are selected the actual switching frequency is switched down to the next lower frequency. Pr 5.37 displays the
actual switching frequency being used.

Closed-loop
When closed-loop vector mode without position feedback is used a filter with a 4ms time constant is automatically included in the speed feedback as
this is required for this system to operate correctly. This will reduce the possible bandwidth of the speed controller compared with the bandwidth
possible when position feedback is used. Particularly when operating above rated speed it may be necessary to include further filtering (Pr 4.12 set to
a value between 1.0 and 5.0ms) to achieve stable operation.
The phase angle between the rotor flux in a servo motor and the encoder position is required for the motor to operated correctly. If the phase angle is
known it can be set in this parameter by the user. Alternatively the drive can automatically measure the phase angle by performing a phasing test (see
Pr 5.12 on page 117). When the test is complete the new value is written to this parameter. The encoder phase angle can be modified at any time and
becomes effective immediately. This parameter has a factory default value of 0.0, but is not affected when defaults are loaded by the user.
The alignment required for zero encoder phase angle (i.e. Pr 3.25 = 0.0) is given below for different feedback devices. Forward rotation of the motor
is produced when Vu leads Vv leads Vw. Although it is not essential, forward rotation of a motor is normally defined as clockwise when looking at the
motor shaft end. When the motor is rotating forwards the motor speed is shown as positive and the position increases.
Encoder with commutation signals (Ab.Servo, Fd.Servo, Fr.Servo)
The alignment required between the no-load motor voltages and the commutation signals for Pr 3.25 = 0 is shown in the following diagram below:
It should be noted that if the encoder is advanced (i.e. the UVW signals are moved to the right with respect to the voltages) the phasing angle in
Pr 3.25 is increased from zero. If the encoder is retarded the phasing angle changes to 359.9° and then reduces towards zero.
The encoder can be aligned statically by connecting the motor to a DC power supply as shown:

The motor will move to one of a number of positions defined by the number of motor pole pairs (i.e. 3 positions for a six pole motor, etc). The encoder
should be adjusted so that the U commutation signal is high, W is low and V is toggling in one of these positions.
Any other feedback device
The alignment required between the no-load motor voltages and the commutation signals for Pr 3.25 = 0 is shown in the diagram below for a 2 or 4
pole motor. For higher numbers of poles 0° should still be aligned as shown, but one electrical cycle shown corresponds to 360°/ (Number of poles /
2). The encoder can be aligned statically by connecting the motor to a DC power supply as already shown. The motor will move to one of a number of
positions defined by the number of motor pole pairs (i.e. 3 positions for a six pole motor, etc). The encoder should be adjusted so that the position
displayed by the drive is n x 65536 / (Number of poles / 2), where n = 0, 1, ... (Number of poles / 2)
It should be noted that if the encoder is advanced (i.e. the encoder is moved so that the angle moves to the right with respect to the voltages) the
phasing angle in Pr 3.25 is increased from zero. If the encoder is retarded the phasing angle changes to 359.9° and then reduces towards zero.
0, drv: Drive encoder
The position feedback from the encoder connected to the drive itself is used to derive the speed feedback for the speed controller and to calculate
the motor rotor flux position.

The position feedback from the Solutions Module in Solutions Module slot 1 is used to derive the speed feedback for the speed controller and to
calculate the motor rotor flux position. If a position feedback category Solutions Module is not installed in slot 1 the drive produces an EnC9 trip.

Parameters common to open-loop and closed-loop modes
Provided the set-up parameters for the drive encoder are correct this parameter shows the encoder speed in rpm.
It should be noted that the value shown by this parameter is measured over a 16ms sliding window period (in the same way as Pr 3.02), and so the
ripple in this parameter accessible via comms or by a Solutions Module is as defined for Pr 3.02. The FI attribute for this parameter is set, and so
further filtering is applied when this parameter is viewed with one of the drive keypads.
These parameters effectively give the encoder position with a resolution of 1/232
ths of a revolution as a 48 bit number as shown below.
Provided the encoder set-up parameters are correct, the position is always converted to units of 1/232
ths of a revolution, but some parts of the value
may not be relevant depending on the resolution of the feedback device. For example a 1024 line digital encoder produces 4096 counts per
revolution, and so the position is represented by the bits in the shaded area only.
When the encoder rotates by more than one revolution, the revolutions in Pr 3.28 increment or decrement in the form of a sixteen bit roll-over counter.
If an absolute position feedback device (except an encoder with commutation signals) is used the position is initialized at power-up with the absolute
position. If a multi-turn absolute encoder is used the revolution counter is also initialized with the absolute revolutions at power-up.
If a linear encoder is used the turns information is used to represent movement by the number of poles defined by Pr 5.11 (or 21.11 for motor map 2).
Therefore if the number of poles is set to two, one revolution is the movement by one pole pitch.

An incremental digital encoder or a SINCOS encoder without communications may have a marker channel. When this channel becomes active it may
be used to reset the encoder position and set the marker flag (Pr 3.31 = 0), or just to set the marker flag (Pr 3.31 = 1). The marker flag is set each time
the marker input becomes active, but it is not reset by the drive, and so it must be cleared by the user.
If Pr 3.35 is set to zero the marker system operates in a conventional manner and only resets the position (Pr 3.29 and Pr 3.30) and not the turns
(Pr 3.28) on a marker event. If Pr 3.35 is set to one the whole position (Pr 3.28 to Pr 3.30) are reset on a marker event. The full reset mode allows the
marker to give a form of registration where the marker event defines zero position.
The marker function only operates when Ab, Fd, Fr, SC, Ab.Servo, Fd.Servo, Fr.Servo type encoders are selected with Pr 3.38.
This parameter has a different function depending on the type of encoder selected with Pr 3.38 and Pr 3.39.

It is sometimes desirable to mask off the most significant bits of the revolution counter with these types of encoders. This does not have to be done for
the drive to function correctly. If Pr 3.33 is zero the revolution counter (Pr 3.28) is held at zero. If Pr 3.33 has any other value it defines the maximum
number of the revolution counter before it is reset to zero. For example, if Pr 3.33 = 5, then Pr 3.28 counts up to 31 before being reset. If Pr 3.33 is
greater than 16, the number of turns bits is 16 and the Pr 3.28 counts up to 65535 before being reset.
SC.Hiper, SC.EnDat, SC.SSI and 03.39 = 1 or 2 (Rotary encoder)
Pr 3.33 must contain the number of bits in the comms message used to give the multi-turn information. For a single turn comms encoder, Pr 3.33
must be set to zero. As well as setting the number of comms turns bits this parameter also sets up a mask on the turns displayed in Pr 3.28 as
described above. With SC.Hiper or SC.EnDat encoders it is possible for this parameter to be obtained automatically from the encoder (see Pr 3.41).
If Pr 3.33 is greater than 16 the number of turns bits is 16.
SC.Hiper, SC.EnDat, SC.SSI and 03.39 = 0 (Linear encoder)
When a linear encoder is selected no mask is placed on the turns information displayed in Pr 3.28, and so this parameter always displays the turns
information as a full 16 bit value with a maximum of 65535. Linear SINCOS encoders with comms are normally specified with a length for each sine
wave period and the length for the least significant bit of the position in the comms message. Pr 3.33 should be set up with the ratio between these
two lengths so that the drive can determine the drive encoder position during initialization. The Linear encoder comms to sine wave ratio is defined as
follows:
With SC.Hiper or SC.EnDat encoders it is possible for this parameter to be obtained automatically from the encoder (see Pr 3.41).
This ratio can be greater than 255 for some EnDat encoders. If this is the case it is possible to use auto-configuration to set up the correct value
provided the ratio is less than or equal to 65535. The value cannot be stored in Pr 3.33 because it will be too large, and so Pr 3.33 is set to 255. Auto-
configuration must be enabled (Pr 3.41=1) and this setting must be saved, so that auto-configuration is carried out at power-up and each time the
drive encoder is initialized. Once auto-configuration has been carried out so that the internally stored value (not visible to the user) is larger than 255,
this value cannot be changed via Pr 3.33. The internal value can be reset to re-enable the function of Pr 3.33 by powering down and then powering up
again, or by auto-configuration with an alternative encoder where the corresponding value for Pr 3.33 is less than or equal to 255.
EnDat, SSI
Pr 3.33 must contain the number of bits in the comms message used to give the multi-turn information. If the encoder gives no turns information, for
example a single turn comms encoder, Pr 3.33 must be set to zero. As well as setting the number of comms turns bits that the drive will attempt to
obtain from the encoder, this parameter also sets up a mask on the turns displayed in Pr 3.28 as described above. With an EnDat encoder it is
possible for this parameter to be obtained automatically from the encoder (see Pr 3.41). If Pr 3.33 is greater than 16 the number of turns bit is 16.
It should be noted that some SSI encoders include leading zeros before the turns information. In this case the number of turns bits should include the
leading zeros.

*Limited to a minimum of 1 except for Ab.Servo, Fd.Servo and Fr.Servo encoders in servo mode and EnDat and SSI encoders in all modes.
Support for non power of 2 encoders was added as follows :
From software version 1.06.00 onwards - SC and SC.Endat type encoders
From software version 01.06.01 onwards - SC.Hiper, SC.SSI, Ab.servo, Fr.servo and Fd.servo type encoders.
For example - a Unidrive SP with software prior to 1.06.01 in servo mode does not store the phase offset if used with a 2000PPR quadrature encoder
When Ab, Fd, Fr, AbServo, Fd.Servo, Fr.Servo, SC, SC.Hiper, SC.EnDat or SC.SSI encoder are used the equivalent number of encoder lines per
revolution must be set-up correctly in Pr 3.34 to give the correct speed and position feedback. This is particularly important if the encoder is selected
for speed feedback with Pr 3.26. The equivalent number of encoder lines per revolution (ELPR) is defined as follows.
For any type of linear encoder one revolution is the motor pole pitch multiplied by the number of poles set up in Pr 5.11 or Pr 21.11.
Ab.Servo, Fd.Servo, Fr.Servo
The incremental (A/B) signal frequency should not exceed 500kHz.
It should be noted that if this parameter is set to zero the incremental signals are ignored and only the UVW commutation signals are used to define
the motor position. See Pr 3.38. If Pr 3.34 or the motor pole pairs defined by either Pr 5.11 or Pr 21.11 (depending on the motor map selected) are
modified and the encoder type is Ab.Servo, Fd.Servo or Fr.Servo then encoder is re-initialized. This ensures that the control position used by the drive
to determine the flux axis of the motor is re-aligned with the commutation signals when the encoder moves again and prevents possible errors.
SC.Hiper, SC.EnDat, SC, SC.SSI
The sine wave signal frequency can be up to 500kHz, but the resolution is reduced at higher frequencies. The table below shows the number of bits
of interpolated information at different frequencies and with different voltage levels at the drive encoder port. The total resolution in bits per revolution
is the ELPR plus the number of bits of interpolated information. Although it is possible to obtain 11 bits of interpolation information, the nominal design
value is 10 bits.
If the position feedback device is a rotary SINCOS encoder with comms the position supplied via comms gives a number of counts per revolution that
is a power of two and the resolution is defined by the single turns comms bit (Pr 3.35). It is assumed therefore that the number of periods per
revolution is also a power of two, and so if a SC.Hiper, SC.EnDat or SC.SSI type devices is selected and Pr 3.39 is 1 or 2 to select a rotary encoder =
1 or 2, Pr 3.34 is forced to be a power of two between 2 and 32768.
When Pr 3.34 is adjusted an Enc7 trip is produced, because the encoder requires re-initialization. If this parameter is set to a value that is not a power
of two and the encoder is set up as a linear encoder (Pr 3.39 = 0) the sample rate for the current controllers is reduced to 6kHz for 6 or 12kHz
switching frequency. All other switching frequencies are unaffected. See Pr 5.37 on page 132.
If the position feedback device is SC.Hiper or SC.EnDat it is possible for the drive to set up this parameter automatically from information obtained
from the encoder (see Pr 3.41 on page 76).
EnDat, SSI
Where encoder comms alone is used as position feedback, the equivalent lines per revolution (Pr 3.34) is not used in setting up the encoder interface.
If auto-configuration is used (see Pr 3.41 on page 76 for details), then Pr 3.34 is set to zero if this is successful.
Linear motors
The value entered in this parameter for a linear motor should be calculated as follows:
If this value is not an integer then an SM-Universal Encoder Plus is required.

Pr 3.35 defines the marker mode. If this parameter is zero the marker system operates in a conventional manner, but if this parameter is non-zero the
marker causes a full position reset.
SC.Hiper, SC.EnDat, SC.SSI and 03.39 = 1 or 2 (Rotary encoder)
Pr 3.35 must be set to the number of comms bits used to represent one revolution of the encoder. The single turn comms resolution may be higher
than the resolution of the sine waves per revolution.
SC.Hiper, SC.EnDat, SC.SSI and 03.39 = 0 (Linear encoder)
Pr 3.35 must be set up to the total number of bits representing the whole encoder position in the comms message. This parameter is not used with
linear SC.Hiper encoders as the number of bits used to represent the whole position is always 32.
EnDat, SSI
Pr 3.35 must be set to the number of bits used to represent one revolution of the encoder.
Although Pr 3.35 can be set to any value from 0 to 32, if the value is less than 1, the resolution is 1 bit. Some SSI encoders (SC.SSI or SSI) include a
power supply monitor alarm using the least significant bit of the position. It is possible for the drive to monitor this bit and produce an Enc6 trip if the
power supply is too low (see Pr 3.40). If the encoder gives this information the comms resolution should be set up to include this bit whether it is being
monitored by the drive or not. It should be noted that some SSI encoders include trailing zeros after the position. This parameter should be set up to
include the trailing zero bits.
It is possible for the drive to set up this parameter automatically from information obtained from the encoder via Hiperface or EnDat interfaces (see
Pr 3.41).
The encoder supply voltage present on the drive encoder connector is defined by this parameter as 0 (5V), 1 (8V), or 2 (15V).
This parameter defines the baud rate for the encoder comms when using SSI or EnDat encoders. However, a fixed baud rate of 9600 baud is used
with HIPERFACE encoders and this parameter has no effect.

Any baud rate can be used when encoder comms is used with a SINCOS encoder to obtain the absolute position during initialization. When encoder
comms is used alone(EnDat or SSI selected with Pr 3.38) the time taken to obtain the comms position must be 160μs or less, otherwise the drive
initiates an Enc4 trip.
There is a delay obtaining the position from an encoder using comms alone. The length of this delay affects the sample rate and timing of the position
used by the drive for control and the position passed to Solutions Modules. If for an EnDat encoder the position within one turn can be obtained in
30μs and the whole comms message including CRC can be obtained in 60μs then fast sampling is used, otherwise slow sampling is used as shown
below. If for an SSI encoder the whole position can be obtained in 30μs fast sampling is used. In each case the position is sampled within the encoder
at the start of the comms message from the drive.
In the example the current/torque sampling rate is 4kHz, but this will change if a different switching frequency is selected. If fast sampling is used the
control position used to define the drive reference frame is obtained every current/torque control sample and the position passed to Solutions
Modules is obtained 20μs before the datum point where other types of encoders are sampled. If slow sampling is used both the control position and
the position passed to Solutions Modules is obtained 150μs before the datum. When fast sampling is used the delay introduced into the control
system by the encoder is less, and so a higher control system bandwidth will be possible. So that the position values from the encoder can be used in
a position control system compensation is provided for the delay in obtaining the position before it is made available to Solutions Modules or in the
drive position parameters so that it appears to have been sampled at the datum. This compensation is based on the delay (i.e. 20μs or 150μs) and
the change of position over the previous sample.
EnDat comms
The following equations are used by the drive to determine the time taken to obtain the position information from an EnDat encoder. These are based
on tcal ≤ 5μs, where tcal is the time from the first clock edge of the position command message from the drive to the first clock edge when the encoder
responds as defined in the EnDat specification. This limit of 5μs may exclude a small number of EnDat encoders from being used by the drive as a
comms only feedback device. It is also assumed that tD ≤ 1.25μs where tD is the data delay from the encoder as defined by the EnDat specification for
105m of cable. Although with higher clock rates shorter cables must be used, and tD will be less than 1.25μs, the calculation performed by the drive
always assumes tD=1.25μs. It should be noted that all values are rounded up to the nearest microsecond.
Command message time = tcommand = 10T or tcal whichever is the longest
Where: T = 1/Baud Rate, tcal = 5μs
Time for single turn position = tcommand + tD + (2 + Single turn resolution) x T
= tcommand + tD + (2 + Pr 3.35) x T
Where: tD = 1.25μs
Time for whole message including CRC = Time for single turn position + (Number of turns bits + 5) x T
= Time for single turn position + (Pr 3.33 + 5) x T
For example an encoder with 12 turns bits, 13 bit single turn resolution and a baud rate of 2M would give the following times:
Time for single turn position = 14μs (13.75μs rounded up)
Time for the whole message including CRC = 23μs (22.25μs rounded up)
A recovery time (tm) is specified for EnDat encoders, that is the time required between the end of one data transfer and the beginning of the next one.
If this time is not allowed between messages that transfer the position from the encoder, the encoder operates in continuous mode and the data from
the encoder will be incorrect and cause CRC errors. tm is nominally 20μs, but may vary from 10μs to 30μs (EnDat 2.1 specification). If tm is greater
than 23μs and 6 or 12kHz switching is used, which have a fast sample rate of 83μs, it is possible for the time allowed for tm to be too short. Therefore
if 6 or 12kHz switching are used the total message transfer time should not exceed 53μs unless tm can be guaranteed to be less than 30μs by a
suitable margin.

The whole position must be obtained from an SSI encoder before it can be used by the drive, therefore the time for the single turn position and the
time for the whole message are the same.
Time to obtain the position= (Number of turns bits + Single turn resolution + 1) x T
= tD + (Pr 3.33 + Pr 3.35 + 1) x T
For example an encoder with 12 turns bits, 13 bit single turn resolution and a baud rate of 1M would give the following time:
Time to obtain the position data = 28μs (27.25μs rounded up)
The drive does not include the recovery time of the encoder in these calculations, therefore the user must ensure that there is sufficient time after the
data transfer before the next transfer begins. If the encoder does not recover in time its output will be low just before the new transfer beings and will
cause an Enc5 trip.
The following encoders can be connected to the drive encoder port.
0, Ab: Quadrature incremental encoder, with or without marker pulse
1, Fd: Incremental encoder with frequency and direction outputs, with or without marker pulse
2, Fr: Incremental encoder with forward and reverse outputs, with or without marker pulse
This type of encoder can be used for motor control in closed-loop vector mode or servo mode. In servo mode a phasing test must be performed after
every drive power-up or encoder trip.
3, Ab.Servo: Quadrature incremental encoder with commutation outputs, with or without marker pulse
4, Fd.Servo: Incremental encoder with frequency, direction and commutation outputs, with or without marker pulse
5, Fr.Servo: Incremental encoder with forward, reverse and commutation outputs, with or without marker pulse
This type of encoder is normally only used in servo mode. If it is used in closed-loop vector mode the UVW signals are ignored. The UVW
commutation signals are used to define the motor position during the first 120° electrical rotation after the drive is powered-up or the encoder is
initialised. If the Drive encoder lines per rev (Pr 3.34) is set to zero the incremental signals are ignored and the drive can run with commutation
signals alone. A phase locked loop is used to smooth the feedback, but particularly at low speeds the motor movement includes a significant
ripple. Low speed loop gains should be used and the drive encoder filter (Pr 3.42) should be set to 16ms.
6, SC: SinCos: Encoder with no serial communications
This type of encoder can be used for motor control in closed-loop vector mode or servo mode. In servo mode a phasing test must be performed
after every drive power-up or encoder trip.
7, SC.Hiper: Absolute SinCos encoder using Stegmann 485 comms protocol (HiperFace).
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. The drive can check the
position from the sine and cosine waveforms against the internal encoder position using serial communications and if an error occurs the drive
initiates a trip. An applications or fieldbus Solutions Module can communicate with the encoder via parameters that are not visible from the
keypad or drive 485 comms.
8, EnDAt: Absolute EnDat only encoder
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. Additional communications
with the encoder from an applications or fieldbus module is not possible
9, SC.Endat: Absolute SinCos encoder using EnDat comms protocol
initiates a trip. An applications or fieldbus Solutions Module can communicate with the encoder via parameters that are not visible from the
keypad or drive 485 comms.
10, SSI: Absolute SSI only encoder
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. Additional communications
with the encoder from an applications or fieldbus module is not possible. SSI encoders use either gray code or binary format which can be
selected with Pr 3.41.

All SINCOS encoders and encoders using communications must be initialized before their position data can be used. The encoder is automatically
initialized at power-up, after trips Enc1 to Enc8 or Enc11 to Enc17 are reset, and when the initialization (Pr 3.47) is set to 1. If the encoder is not
initialized or the initialisation is invalid the drive initiates trip Enc7.
Ab, Fd, Fr, Ab Servo, Fd Servo, Fr Servo - Drive encoder termination select
The terminations may be enabled/disabled by this parameter as follows:
SC - Drive encoder termination select
SC.Hiper, SC.EnDat, SC.SSI - Rotary encoder select
If Pr 3.39 is set to 1 or 2 the encoder is a rotary encoder and the following apply:
1. Pr 3.33 defines the number of turns bits in the comms message from the encoder and a mask is applied to Pr 3.28 to remove turns bits in excess
of those provided in the encoder comms position.
2. The number of encoder lines per revolution defined by Pr 3.34 is forced to a power of two between 2 and 32768.
3. Pr 3.35 defines the number of comms bits used to define a single turn.
If Pr 3.39 is set to 0 the encoder is a linear encoder and the following apply:
1. Pr 3.33 defines the ratio between the length of a sine wave period and the length of the least significant comms bit.
2. No mask is applied to the turns displayed in Pr 3.28.
3. Pr 3.35 defines the number of comms bits used to give the whole position value.
If the position feedback device is SC.Hiper or SC.EnDat it is possible for the drive to set up this parameter automatically from information obtained
from the encoder (see Pr 3.41).
EnDat, SSI - Comms only encoder mode
If this parameter is set to 1 or 2 the drive always takes the complete absolute position for these comms only type encoders. The turns (Pr 3.28),
position (Pr 3.29) and fine position (Pr 3.30) will be an exact representation of the position from the encoder. If the encoder does not provide 16bits of
turns information, the internal representation of the turns used by the position controller in Menu 13 and functions within the SM-Applications Module
such as the Advanced Position Controller, rolls over at the maximum position value from the encoder. This jump in position is likely to cause unwanted
effects. As the SSI format does not include any error checking it is not possible for the drive to detect if the position data has been corrupted by noise
on the encoder signals. The benefit of using the absolute position directly from an SSI encoder is that even if the encoder communications are
disturbed by noise and position errors occur, the position will always recover the correct position after the disturbance has ceased. The EnDat format
includes a CRC that is used by the drive to detect corrupted data, and so if the position data has been corrupted the drive uses the previous correct
data until new uncorrupted data is received.
It should be noted that if the encoder does not provide at least 6 bits of turns information the speed feedback used to generate the drive over speed
trip is incorrect when the position rolls over or under the maximum value. Therefore this mode should not be used with encoders that do not provide
this turns information unless the encoder is not going to pass through the maximum position.
If this parameter is set to 0 the drive only takes the absolute position directly from the encoder during initialization. The change of position over each
sample is then used to determine the current position. This method always gives 16 bits of turns information that can be used without jumps in
position by the position controller in Menu13 and SM-Applications modules etc. This method will only operate correctly if the change of position over
any 250μs period is less than 0.5 of a turn, or else the turns information will be incorrect. The turns can then only be corrected by re-initializing the
encoder. Under normal operating conditions and at a maximum speed of 40,000rpm the maximum change of position is less than 0.5 turns, however,
if noise corrupts the data from an SSI encoder it is possible to have apparent large change of position, and this can result in the turns information
becoming and remaining corrupted until the encoder is re-initialized.

This problem should not occur with EnDat encoders because three consecutive corrupted messages at the slowest sample rate (i.e. 25μs) would be
required even at the maximum speed of 40,000rpm before the change of position would be the required 0.5 turns to give possible corruption of the
turns information. If three consecutive messages with CRC errors occur this will cause the drive to produce an Enc5 trip. The drive can only be re-
enabled after the trip is reset which will re-initialize the encoder and correct the absolute turns.
If an SSI encoder is used, but is not powered from the drive, and the encoder is powered up after the drive, it is possible that the first change of
position detected could be large enough to cause the problem described above. This can be avoided if the encoder interface is initialized via Pr 3.47
after the encoder has powered up. If the encoder includes a bit that indicates the status of the power supply the power supply monitor should be
enabled (see Pr 3.40). This will ensure that the drive remains tripped until the encoder is powered up and the action of resetting the trip will reinitialise
the encoder interface.
If the position feedback device is EnDat it is possible for the drive to set up this parameter automatically from information obtained from the encoder
(see Pr 3.41).
Trips can be enabled/disabled using Pr 3.40 as follows.

+These trips can be enabled/disabled by Pr 3.40
1. If the terminations are not enabled on the A, B or Z inputs the wire break system will not operate. (Note that as default the Z input terminations
are disabled to disable wire break detection on this input).
2. Phase error for a servo type encoder is to detect that the incremental pulses have been counted incorrectly. The error is detected if the
incremental position moves by 10° with respect to the position defined by the UVW commutation signals. The trip is initiated if the error is
detected for 10 consecutive samples.
3. Phase error for SinCos encoders with comms is detected by interrogating the encoder every second via comms to compare the incremental
position determined from the sine waves with the incremental position via comms. If the error is greater than 10° for 10 consecutive samples the
trip is initiated. It should be noted that this system should not be used where 180 x Pr 5.11 (or Pr 21.11 for motor map 2) / Pr 3.34 is greater than
10° or else incorrect EnC3 trips will occur.
4. Incorrect encoder phasing is detected if the motor reaches half of the speed defined by SPEED_FREQ_MAX and the phasing error is larger
enough for the motor to accelerate uncontrollably. It can be disabled by setting Pr 3.08 to any value greater than zero.
5. This trip can also be caused when data is transferred between the encoder and a Solutions Module, such as an SM-Applications module, and an
error other than those covered by EnC5 or EnC6 occurs.
Wire-break detection
It may be important to detect a break in the connections between the drive and the position feedback device. This feature is provided for most
encoder types either directly or indirectly as listed below.
Encoder initialisation
Encoder initialisation will occur as follows: at drive power-up, when requested by the user via Pr 3.47, when trips PS.24V or Enc1 to Enc8 or Enc11 to
Enc17 are reset. Initialisation causes an encoder with comms to be re-initialized and auto-configuration to be performed if selected. After initialisation
Ab.Servo, Fd.Servo and Fr.Servo encoders will use the UVW commutations signals to give position feedback for the first 120deg (electrical) of
rotation when the motor is restarted.
A delay is provided during initialisation for some encoders to allow the encoder to be ready to provide position information after it has powered up.
The delay is provided during initialisation because this occurs during drive power-up and after encoder power supply trips are reset. The delays are as
follows:
Encoder power supply trips
The encoder power supply from the drive can be switched off by the drive either because the encoder power supply is overloaded (Enc1 trip) or
because the internal 24V supply within the drive is overloaded (PS.24V trip). The internal 24V supply provides power for the encoder power supply,
user 24V output, digital I/O, Solutions Modules etc.
SC.EnDat, EnDat
The number of encoder turns read from the encoder during auto-
configuration is not a power of 2
Enc13

The number of bits defining the encoder position within a turn read from the
encoder during auto-configuration is too large.

configuration.

The differential levels of the sine and cosine waveforms are

is less than the value produced by two valid waveforms with a
differential peak to peak magnitude of 0.25V (1/4 of the nominal
level). This detects wire break in the sine and cosine connections.
Enc2

Wire break detection is difficult with these devices. However, if
power supply monitoring is enabled the drive will be looking for a
one at the start of the message and a zero to indicate that the power
supply is okay. If the clock stops or the data line is disconnected the
data input to the drive may stay in one state or the other and cause a
trip.

To ensure that an Enc1 trip is not initiated when the internal 24V is overloaded, and subsequently switched off by the drive, there is a delay of 40ms
in the detection of Enc1 trip. It is possible for other encoder trips such as wire break detection (Enc2) to occur when the power supply is removed from
the encoder. Therefore overloading the internal 24V supply or the encoder supply could result in an immediate Enc2 trip. To ensure that the correct
reason for the trip is given PS.24V and Enc1 trips override an existing Enc2 to Enc8 or Enc11 trip. This means that both the original trip (Enc2 to Enc8
or Enc11) and then the new trip (PS.24V or Enc1) are stored in the trip log.
When a SC.Hiper, SC.EnDat or EnDat encoder is being used, the drive will interrogate the encoder on power-up. If Pr 3.41 is set to one and the
encoder type is recognized based on the information provided by the encoder, the drive will set the encoder turns / linear encoder comms to sine
wave ratio (Pr 3.33), the equivalent lines per revolution (Pr 3.34) and the encoder comms resolution / linear encoder comms bits (Pr 3.35). For
SC.Hiper or SC.EnDat encoders the rotary encoder select (Pr 3.39) is also set up. If the encoder is not recognized, there is a comms error or the
resulting parameter values are out of range the drive initiates an Enc7 or Enc12 to Enc17 trip to prompt the user to enter the information. The drive
can auto-configure with any of the following devices.
Rotary EnDat encoders
The encoder turns, comms resolution and equivalent lines per rev are set up directly using the data read from the encoder.
Linear EnDat encoders
The comms resolution is set to the number of bits required for the whole position within the position data messages from the encoder. The linear
encoder comms to sine wave ratio is calculated from the sine wave period and LS comms bit length. The encoder does not give the equivalent lines
per rev directly, but gives the length of a sinewave period in nm. Therefore the drive uses the pole pitch (Pr 5.36 or 21.31) and the number of motor
poles (Pr 5.11 or 21.11) for the current active motor (defined by Pr 11.45) to calculate the equivalent lines per revolution.
ELPR = Pole pitch x Number of motor pole pairs / Length of a sinewave
Normally the Number of motor poles will be set to 2, and so
ELPR = Pole pitch / Length of a sinewave
It should be noted that the equivalent lines per rev parameter is only updated when auto-configuration occurs, i.e. when the encoder is initialized, and
that it uses the pole pitch for the currently active motor. The value for Pole pitch x Number of motor pole pairs is limited to 655.35mm by the drive. If
the pole pitch is left at its default value of zero which would give ELPR = 0, or the result of the calculation is over 50000, the drive will initiate an Enc15
trip.
Rotary hiperface encoders
The drive can recognize any of the following devices: SCS 60/70, SCM 60/70, SRS 50/60, SRM 50/60, SHS 170, SCS-KIT 101, SKS36, SKM36. If
the drive cannot recognize the encoder type it will initiate Enc12 trip.
Linear Hiperface encoders
The drive can recognize the LINCODER. The calculations used for linear EnDat encoders are also used to determine the equivalent lines per
revolution. However, the length of a sine wave is fixed at 5mm.
EnDat encoders
If the encoder type is EnDat comms only then after auto-configuration parameter 03.39 is set to zero if the number of turns bits is less than 6. This
automatically selects absolute mode and prevents over speed trips at the encoder roll-over points which would otherwise occur.
SSI, SC.SSI
SSI encoders normally use gray code data format. However, some encoders use binary format which may be selected by setting this parameter to
one.
0 = 0ms, 1 = 1ms, 2 = 2ms, 3 = 4ms, 4 = 8ms, 5 = 16ms
A sliding window filter may be applied to the feedback taken from the drive encoder. This is particularly useful in applications where the drive encoder
is used to give speed feedback for the speed controller and where the load includes a high inertia, and so the speed controller gains are very high.
Under these conditions, without a filter on the feedback, it is possible for the speed loop output to change constantly from one current limit to the other
and lock the integral term of the speed controller.

In closed-loop vector mode, if Pr 3.24 is set to 1 or 3 so that the drive is operating without position feedback, this parameter also defines a filter on the
output of the speed estimator which is used as the speed feedback. A filter with a 4ms time constant is always present on the output of the speed
estimator, but this filter may be extended as follows: 0 = 4ms, 1 = 8ms, 2 = 16ms, 3 = 32ms, 4 = 64ms, 5 = 128ms. The output of the speed estimator
can include some ripple, which increases as the drive passes into field weakening and the filter can be used to remove this ripple. This is particularly
useful when using standard ramp or spinning start with a low friction high inertia load, and can prevent over voltage trips when the drive has no
braking resistor.
The drive encoder input can be used as a reference to control a drive parameter. The drive encoder reference parameter (Pr 3.45) gives the speed of
the encoder input as a percentage of the maximum drive encoder reference provided that the number of encoder lines per revolution (Pr 3.34) has
been set up correctly. This may then be scaled and routed to any non-protected drive parameter.

At power-up Pr 3.48 is initially zero, but is set to one when the drive encoder and any encoders connected to position category modules have been
initialized. The drive cannot be enabled until this parameter is one.
If any trips occur that could indicate that the encoder system is no longer initialized correctly (i.e. Enc2-Enc8 and Enc11-Enc17), or the internal 24V or
encoder power supplies are overloaded (i.e. Enc1 or PS.24V), Pr 3.48 is set to zero and the drive cannot be enabled until the encoder is re-initialized.
It is likely that the failure of either of these supplies will cause one of the other encoder trips and it should be noted that Enc1 or PS.24V trips can
override Enc2-Enc8 and Enc11-Enc17 trips so that the power supply overload is not mistaken for an encoder error.
When this parameter is set to one, additional information for the motor object can be transferred from Pr 18.11 to Pr 18.17 as shown below.
If Pr 3.50 is set to one Pr 3.28, Pr 3.29 and Pr 3.30 are not updated. If this parameter is set to zero these parameters are updated normally.
5.5.1 Communication with Hiperface and EnDat encoders
It is possible to use the communications channel between the drive and a Hiperface or EnDat encoder. This allows access to the encoder functions
including reading the encoder position and, reading and writing to encoder memory. The system can be used to communicate with SC.Hiper and
SC.EnDat type encoders provided that the position checking system has been disabled, by setting Pr 90.21 to one.
To send a message to the encoder the required message must be written to the transmit register (Pr 90.22). To read the response from the encoder
the data is read from the receive register (Pr 90.23).
Bits 13-15 of the registers are used to indicate the following:
Data should be written to the transmit register (Pr 90.22) when the register has been reset to zero by the drive. The data will be transferred to the
comms buffer and the transmit register will be cleared.
Data can be read from the receive register (Pr 90.23) at any time. If there is receive data in the buffer bit 15 will be set. Once the data has been read
the register should be cleared and the drive will then transfer more data.

The actual encoder comms buffer is 16 bytes long and any messages that exceed this length (including the checksum added for Hiperface) will cause
an error. The status flags are defined as follows:
SC.Hiper type encoders
The Stegmann Hiperface comms protocol is an asynchronous byte based system. Up to 15 bytes of data can be written to the buffer. The first byte
should be the encoder address. The checksum will be calculated by the drive and added to the end of the message before the message is transmitted
to the encoder. The drive checks the checksum of the received message. If successfully received, the receive message can be read via the receive
register (Pr 90.23) including the address and the checksum received from the encoder. It should be noted that the encoder must be set up for 9600
baud, 1 start bit, 1 stop bit and even parity (default set-up) for the encoder comms to operate with the drive. Also the data block security should not be
enabled in the encoder if the drive encoder nameplate system is to operate correctly.
The following commands are supported:
Example of a Hiperface transfer: read position
Disable drive encoder position check by setting Pr 90.21 to one. This should be set back to zero at the end of the transfer if encoder position checking
is required.
Transfer the "read position" message to the encoder comms buffer by writing the sequence of words shown in the table below to Pr 90.22. A check
should be carried out before each word is written to ensure that the parameter is zero (i.e. the drive has taken any previous data).
As bit 14 of the second word is set to one the drive will add the checksum and transfer this message to the encoder. When the encoder response has
been received by the drive the first byte of the message will be placed in the least significant byte of Pr 90.23 and bit 15 will be set to one. This data
should be read and the parameter cleared so that the drive will put the next byte into this parameter. The sequence of data that should appear in
Pr 90.23 for an encoder with an address of 0x40 and a position of 0x03, 0x59, 0x63, 0x97 is shown in the table below.

Figure 5-5 Menu 3 Regen logic diagram
In Regen mode some form of charging system must be used to limit the current taken from the supply to charge the d.c. link capacitors when the
supply is first connected to the drive inverter terminals (i.e. UVW). Either an external soft start resistor or the charging system in the drive may be
used. See Unidrive SP Regen Installation Guide for details. When the d.c. link capacitors are charged a contactor, controlled by the drive, is closed to
either short out the external charging resistor, or to disconnect the charging system and connect the drive inverter terminals directly to the supply. This
contactor is controlled by Pr 3.07 which is normally used as the source for the drive relay. An auxiliary contact on this contactor is monitored in Pr 3.08
which normally follows the state of digital I/O 2.
A current feedback trimming routine runs before the drive is enabled to minimize offsets in the current feedback. Unnecessary offsets can be caused
by the current taken from the supply to power the drive control electronics or by current pulses due to noise on the supply during the current trimming
period. If an external charging resistor is used and the shorting contactor is open the additional supply resistance can reduce the peak level of these
currents. If the charge system in the drive is used and the contactor is open the drive inverter terminals are not connected to the supply, and so there
is no current flowing into the drive inverter terminals. Therefore the drive will always ensure that the contactor is open while the current trimming
system is active. Two alternative strategies can be selected with Pr 3.11:
1. The first strategy (Pr 3.11=0) activates current trimming immediately after the supply is applied to the drive before the contactor is closed. Current
trimming is not carried out again unless the drive is powered down and powered up again.
2. The second strategy (Pr 3.11=1) activates current trimming after power up before the contactor is closed and again each time just before the drive
is enabled. Because the contactor must be open during current trimming the contactor is opened when the drive enable is applied, the current
trimming is performed, the contactor is closed and then the drive is enabled. If the enable is active during power-up with this strategy, current
trimming is only carried out once before the contactor is closed.

The drive checks for mains loss either by monitoring the d.c. link or additionally when the inverter is active by an internal estimate of the a.c. supply
level. The detection levels used for different drive voltage ratings are given in the following table.
During power-up the supply is considered okay and the drive can operate if the d.c. link voltage is above the levels given in the table below.
The operation of the drive in regen mode is shown in the state machine below.
The power (Pr 5.03) and the reactive power (this parameter) are the power or VAR's respectively that flow from the supply to the drive. Therefore
when this parameter is positive the phase current flowing from the supply to the drive contains a component that lags the respective phase voltage,
and when this parameter is negative the phase current contains a component which leads the respective phase voltage at the drive terminals.

At power-up this parameter is zero. Each time the regen unit is enabled the supply inductance is measured and displayed by this parameter. The
value given is only approximate, but will give an indication as whether the input inductance is correct for the sinusoidal rectifier unit size. The
sinusoidal filter capacitance masks the effect of the supply inductance, therefore the value measured is usually the regen unit input inductor value.
If an L.Sync trip occurs Pr 3.03 indicates the reason. At power-up and on trip reset this parameter is set to zero. Once an L.Sync trip has occurred this
parameter shows when the trip occurred and the reason for the last L.Sync trip as indicated by the bits in the table below. The reasons for the trip are
either because the supply frequency is out of range or the PLL (phase lock loop) within the drive cannot synchronize to the supply waveforms.
Pr 3.04 defines the action taken after enable and when a synchronization failure occurs.
0, rESYnC: Continuously attempt to re-synchronize

The sinusoidal rectifier unit will attempt to hold the DC bus at the level specified by this parameter. The bus voltage must always be higher than the
peak of the line to line supply voltage if the unit is to operate correctly. The default values can be used with most supplies giving a reasonable level of
control headroom. However, with higher voltage supplies the set-point must be raised.
When the drive is operated as a regen unit it uses a DC bus voltage controller with inner current controllers as shown below.
The gains of the voltage and current controllers affect the stability of the regen unit control system and incorrect gain settings can result in over-
voltage or over-current trips. In many applications the default gains given for the current controllers (Pr 4.13 and Pr 4.14) will be suitable, however, it
may be necessary for the user to change these if the inductance or resistance of the supply plus the regen inductors varies significantly from the
expected values.
Setting the current controller gains
The most critical parameter for stability is the current controller proportional gain (Pr 4.13). The required value for this is dependent on the regen unit
input inductance. If the inductance of the supply is a significant proportion of the recommended regen inductor (i.e. 60/IDR mH per phase, where IDR
is equivalent to Kc), then the proportional gain may need to be increased. The supply inductance is likely to be negligible compared to the regen
inductor value with small drives, but is likely to be significant with larger drives. The proportional gain should be adjusted as described for Pr 4.13
(closed-loop modes) using the total inductance per phase. The current controller integral gain is not so critical, and in a majority of cases the default
value is suitable. However, if it is necessary to adjust this parameter it should be set up as described for Pr 4.14 (closed-loop modes) using the supply
resistance for one phase.
Setting the voltage controller gain
Even when the gains are set correctly there will be a transient change of DC bus voltage when there is a change in the load on any drive connected
to the regen unit. This can be reduced substantially by using an analog input for power feed forward compensation (see Pr 3.10). The following
discussion relates to a system without power feed-forward compensation.
If the power flow from the supply is increased (i.e. more power is taken from the supply or less power is fed back into the supply) the DC bus voltage
will fall, but the minimum level will be limited to just below the peak rectified level of the supply provided the maximum rating of the unit is not
exceeded. If the power flow from the supply is reduced (i.e. less power is taken from the supply or more power is fed back into the supply) the DC bus
voltage will rise. During a rapid transient the bus will rise and then fall as shown below.

The example shown is for a very rapid load change where the torque reference of the motor drive has been changed instantly from one value to
another. The proportional gain of the voltage controller defines the voltage transient because the integral term is too slow to have an effect. (In
applications where the motor drive is operating under speed control, the speed controller may only require a limited rate of change of torque demand,
and so the transient voltage may be less than covered in the discussion below). If the set point voltage (Pr 3.05) plus the transient rise exceed the
over-voltage trip level the regen unit will trip.
When a 400V motor is operated above base speed from a drive in vector mode, fed from the regen unit with the same rating supplying a DC voltage
of 700V, and an instantaneous change of torque is demanded (i.e. -100% to +100%) the peak of the voltage transient (ΔV) is approximately 80V if the
current controllers are set up correctly and the voltage controller uses the default gain. (Operating with maximum voltage on the motor, i.e. above
base speed, gives the biggest transient of power and hence the biggest value of ΔV).
If the load change, drive voltage rating, motor voltage or DC bus set-point are different then ΔV is calculated from:
ΔV = 80V x KL X KRAT x KMV X KSP
Where:
KL = load change / 200%
KRAT = Drive voltage rating / 400
KMV = Motor voltage / 400
KSP = 700 / DC bus voltage set point
In some applications, particularly with a high DC bus voltage set point and low switching frequency it may be necessary to limit the rate of change of
power flow to prevent over voltage trips. A first order filter on the torque reference of the motor drive (i.e. using Pr 4.12) is the most effective method
to reduce the transient further. (A fixed limit of the rate of change of torque demand is less effective). The following table gives an approximate
indication of the reduction in ΔV for different time constants. (As already mentioned the value of ΔV given if for an instantaneous change of torque
representing the worst case. In applications where a speed controller is used in the motor drive the transient will already include an inherent filter).
The transient produced is approximately proportional to the voltage controller gain. The default voltage controller gain is set to give a value that is
suitable for most applications. The gain may need to be increased if the DC bus capacitance is high compared to two drives of similar rating coupled
together. However, care must be taken to ensure that the gain is not too high as this can cause excessive ripple in the DC bus voltage.
The contactor should be controlled by this parameter. When regen mode is selected this bit is routed to digital I/O7 (T41/42 - relay output) as default.
This output, or an alternative output, should be used to control the contactor.

When regen mode is selected Pr 3.08 is the destination from digital I/O2 (T25) with the I/O set up as an input as default. This input, or an alternative
input, should be connected to an auxiliary contact on the contactor so that it follows the state of the contactor..
When the unit has been enabled and successfully synchronized this bit will become active. If the regen unit attempts to re-synchronize or trips, this bit
becomes inactive. When regen mode is selected this bit is routed to a digital I/O1 (T24) with the I/O set up as an output as default. The output, or an
alternative output, should be used to enable the motor drive(s) connected to the DC Bus link of the regen unit.
Power feed-forward compensation can be used to reduce the transient DC Bus link voltage produced when a fast load transient occurs on drives
connected to the Regen unit. 100.0% power feed-forward is equivalent to an active current of Kc / 0.45 (i.e. over current trip level) and an AC terminal
peak phase voltage equal to DC_VOLTAGE_MAX / 2. This scaling is the same as the power output from Pr 5.03 when high speed output mode is
used (see Menu 7). Therefore an analog output of the drive supply the load and analog input 2 or 3 of the drive acting as the supply Regen unit can
be connected together to give power feed-forward compensation without further scaling if the two drives are of equal rating. If the ratings are different
the analog input scaling must be used to give the correct power feed-forwards, where the scaling is given by Load drive Kc / Regen unit Kc.
This parameter defines the strategy used for current trimming in regen mode. If Pr 3.11 = 0 then current trimming is only carried out once after power-
up. If Pr 3.11 = 1 current trimming is carried out after power-up and then before the drive runs each time it is enabled.

5.6 Menu 4: Torque and current control
The scaling of the current feedback is based on the rating of the drive as follows:
Current scaling (Kc) is 1 per unit current and is related to the scaling of the drive current feedback. For most drive sizes Kc is the same as the
Maximum heavy duty current rating defined by Pr 11.32. The Maximum heavy duty current rating is the maximum value of rated motor current
(defined by Pr 5.07 or Pr 21.07) that can be set for operation with the force vented motor protection characteristic - Pr 4.25 = 0 (see Pr 4.16 for more
details). If the Kc and Maximum heavy duty current rating are the same then the drive uses 1.75 x Maximum heavy duty current rating for the open-
loop peak limit and the maximum standard operating current for closed-loop modes. This is the limit up to which the drive can control current normally.
The current range above this is allowed for current controller overshoot and for additional current feedback pulses associated with long cable
operation. For some drive sizes the Maximum heavy duty current rating is larger than Kc, therefore the potential overload is reduced below 1.75 x Kc.
The motor rated current (defined by Pr 5.07 or Pr 21.07) may be increased above the maximum Heavy Duty current rating up to the maximum Normal
Duty rated current . When the motor rated current is above the maximum Heavy Duty current rating the drive always provides motor protection
scheme that is intended for variable torque applications (see Pr 4.16 on page 105 for more details). The maximum rated current is the maximum rated
current allowed for Normal Duty operation.
Table below gives the current scaling (Kc), Maximum heavy duty current rating and Maximum normal duty rated current for all drive sizes and voltage
ratings.

SPMAxxxx and SPMDxxxx drive modules can be connected in parallel provided all power modules have the same voltage and current rating to make
a larger drive. The currents are then defined as follows:
Current scaling (Kc)
Kc is the sum of Kc for all the modules..
Maximum heavy duty current rating
Maximum heavy duty current rating = 0.95 x Sum of maximum heavy duty current rating for all the modules
Maximum rated current
Maximum rated current = 0.95 x Sum of maximum normal duty rated current for all the modules
5.6.1 Open-loop
In this mode the drive operates in the stator flux reference frame under steady state conditions. The absolute maximum controlled motor current is
defined by the peak limit system as 1.75 x Kc. However, the drive does not normally operate at this level, but uses the peak limit system as protection
against over-current trips. Under normal operation the motor current is limited to 1.50 x Kc, allowing a safety margin between the maximum normal
operating current and the peak limit level. Therefore a motor with the same current rating as the drive can produce at least 150% torque when the
drive operates in current limit.
DRIVE_CURRENT_MAX is full scale current feedback, i.e. Kc / 0.45.
The relationship between the voltage and current for open-loop operation is shown in the following vector diagram.
Definitions:
vs = motor terminal voltage vector
is = motor current vector
isy = y axis component of current
isx = x axis component of current
v* = no load y axis voltage reference
MOTOR1_CURRENT_LIMIT_MAX is used as the maximum for some parameters such as the user current limits. This is defined in the vector
diagram as follows (with a maximum of 1000%):
Where
(MOTOR2_CURRENT_LIMIT_MAX is calculated from the motor map 2 parameters)
The Maximum current is either (1.5 x Kc) when the rated current set by Pr 5.07 (or Pr 21.07 if motor map 2 is selected) is less than or equal to the
Maximum Heavy Duty current rating, otherwise it is (1.1 x Maximum Normal Duty rated current).
For example, with a motor of the same rating as the drive and a power factor of 0.85, the maximum current limit is 165.2% for Heavy Duty operation.
The above calculation is based on the assumption that the flux producing current (Pr 4.17) in the stator flux reference frame does not vary with load
and remains at the level for rated load. This is not the case and the flux producing current will vary as the load is increased. Therefore the maximum
current limit may not be reached before the drive reduces the current limit to prevent the peak limit from becoming active.

The rated active and rated magnetising currents are calculated from the power factor (Pr 5.10) and motor rated current (Pr 5.07) as:
rated active current = power factor x motor rated current
rated magnetising current = √(1 - power factor2) x motor rated current
In this mode of operation the drive only requires the motor rated current and the power factor at rated load to set up the maximum current limits, scale
the current limits correctly and calculate the rated active and magnetizing currents. The user may enter the nameplate values in Pr 5.07 and Pr 5.10
respectively and the drive will operate satisfactorily. Alternatively the drive can perform an auto-tune test on the motor to measure the power factor at
rated load by measuring Rs (stationary test), σLs (stationary test), and Ls (rotating test). See Pr 5.12 on page 117 for details.
5.6.2 Closed-loop vector
In this mode the drive operates in the rotor flux reference frame. The maximum normal operating current is controlled by the current limits.
The relationship between the voltage and current for Closed-loop vector operation is shown in the following vector diagram.
Definitions:
isy = y axis component of current
isx = x axis component of current
MOTOR1_CURRENT_LIMIT_MAX is used as the maximum for some parameters such as the user current limits. The magnetizing current (isx)
remains constant except in field weakening where it is reduced to control the motor voltage. The maximum current limit is defined as follows (with a
maximum of 1000%):
Where:
ϕ1 = cos-1
(PF) - ϕ2
The Maximum current is either (1.75 x Kc) when the rated current set by Pr 5.07 (or Pr 21.07 if motor map 2 is selected) is less than or equal to
the maximum Heavy Duty current rating, otherwise it is (1.1 x maximum Normal Duty current rating).
ϕ1 can be derived directly by the drive auto-tune. However, if the auto-tune is not carried out ϕ1 is derived from ϕ2 and the power factor. It should be
noted that the drive autotune would make the total y axis voltage under rated load conditions equal to the rated voltage (VR), therefore ϕ2 is given by
the following equation.

inductors is small, the reference frame is approximately aligned with the supply voltage. The maximum normal operating current is controlled by the

It is possible to set a level of reactive current with Pr 4.08 in regen mode. This parameter has a limit defined as REGEN_REACTIVE_MAX that is

This parameter is the r.m.s. current from each output phase of the drive. The phase currents consist of an active component and a reactive
component. The three phase currents can be combined to form a resultant current vector as shown below:
The resultant current magnitude is displayed by this parameter. The active current is the torque producing current for a motor drive and the real
current for a regen unit. The reactive current is the magnetizing or flux producing current for a motor drive.
Open-loop, Closed-loop vector and Servo
The active current is the torque producing current in a motor drive.
The active current is aligned with the y axis of the reference frame. In open-loop mode the x axis of the reference frame is aligned with the stator flux
vector. In Closed-loop vector and Servo modes the x axis of the reference frame is aligned with the rotor flux vector. The motor torque is proportional
to the torque producing current when field weakening is not active. Once field weakening is active the torque producing current is boosted to
compensate for the reduction in motor flux.
Regen
The active current is the real current in a regen unit.
The active current is aligned with the y axis of the reference frame. The y axis of the reference frame is aligned with the regen unit terminal voltage
vector.

The torque demand is the sum of the torque reference (Pr 4.08) and the torque offset (Pr 4.09), if enabled. The units of the torque demand are % of
rated torque. 100% rated torque is defined as the torque produced by 100% rated active current.
Closed-loop vector
The torque demand can be derived from the speed controller and/or the torque reference and offset. The units of the torque demand are % of rated
torque. 100% rated torque is defined as the torque produced by 100% rated active current.
Open-loop
The current demand is derived from the torque demand. Provided the motor is not field weakened the torque and current demands are the same. In
field weakening the current demand is increased with reduced flux:
Pr 4.04 = Pr 4.03 x frequency / rated frequency
The current demand is subject to the current limits.
The current demand is derived from the torque demand. Provided the motor is not field weakened the torque and current demands are the same. In
the field weakening range the current demand is increased with reduced flux unless Pr 5.28 = 1. The level of flux is derived from the motor model
within the drive controllers.
Pr 4.04 = Pr 4.03 x flux / rated flux

The current demand is the output of the voltage controller in Menu 3 subject to the current limits.

* These are the maximum default values. If the variable maximum of this parameter (MOTOR1_CURRENT_LIMIT_MAX) gives a lower value with the
default value of Motor rated current (Pr 5.07) the default of this parameter is at the lower value.
Open-loop
The motoring current limit applies in either direction of rotation when the machine is producing motoring torque. Similarly the regen current limit
applies in either direction when the machine is producing regenerating torque. The symmetrical current limit can override either motoring or
regenerating current limit if it is set at a lower value than either limit.
The current limits are compared with the active current and if the current exceeds a limit the error value passes through the PI controller to give a
frequency component which is used to modify the ramp output. The direction of the modification is always to reduce the frequency to zero if the active
current is over the motoring limit, or to increase the frequency towards the maximum if the current is over the regenerating limit. Even when the
current limit is active the ramp still operates, therefore the proportional and integral gains (Pr 4.13 and Pr 4.14) must be high enough to counter the
effects of the ramp. See Pr 4.13 and Pr 4.14 on page 103 for gain setting.
The motoring current limit applies in either direction of rotation when the machine is producing motoring torque. Similarly the regen current limit

In regen mode it is possible to produce some current in the x axis of the reference frame so that the regen unit can be made to produce or consume
reactive power. This parameter defines the level of reactive current as a percentage of the regen mode rated current (Pr 5.07). Positive reactive
current produces a component of current flowing from the supply to the drive at the regen unit terminals that lags the respective phase voltage, and
negative reactive current produces a component of current that leads the respective voltage. It should be noted that the maximum current in regen
mode is limited to DRIVE_CURRENT_MAX, and so the drive applies a limit to this parameter (REGEN_REACTIVE_MAX) to limit the current
magnitude. Therefore the symmetrical current limit (Pr 4.07) must be reduced below its maximum value before this parameter can be increased from
zero.
The torque offset is added to the torque reference when Pr 4.10 is one. The torque offset is updated every 4ms when connected to an analog input,
and so Pr 4.08 should be used for fast updating if required.
Open loop
If this parameter is 0 normal frequency control is used. If this parameter is set to 1 the current demand is connected to the current PI controller giving
closed loop torque/current demand as shown below. The current error is passed through proportional and integral terms to give a frequency reference
which is limited to the range ±SPEED_FREQ_MAX .

When this parameter is set to 1, 2 or 3 the ramps are not active while the drive is in the run state. When the drive is taken out of the run state, but not
disabled, the appropriate stopping mode is used. It is recommended that coast stopping or stopping without ramps are used. However, if ramp stop
mode is used the ramp output is pre-loaded with the actual speed at the changeover point to avoid unwanted jumps in the speed reference.
0: Speed control mode
The torque demand is equal to the speed loop output.
1: Torque control
The torque demand is given by the sum of the torque reference and the torque offset, if enabled. The speed is not limited in any way, however, the
drive will trip at the overspeed threshold if runaway occurs.
2: Torque control with speed override
The output of the speed loop defines the torque demand, but is limited between 0 and the resultant torque reference (Pr 4.08 + Pr 4.09 (if
enabled)). The effect is to produce an operating area as shown below if the final speed demand and the resultant torque reference are both
positive. The speed controller will try and accelerate the machine to the final speed demand level with a torque demand defined by the resultant
torque reference. However, the speed cannot exceed the reference because the required torque would be negative, and so it would be clamped
to zero.
Depending on the sign of the final speed demand and the resultant torque the four areas of operation shown below are possible.
This mode of operation can be used where torque control is required, but the maximum speed must be limited by the drive.
3: Coiler/uncoiler mode
Positive final speed demand: a positive resultant torque will give torque control with a positive speed limit defined by the final speed demand. A
negative resultant torque will give torque control with a negative speed limit of -5rpm.
Negative final speed demand: a negative resultant torque will give torque control with a negative speed limit defined by the final speed demand. A
positive resultant torque will give torque control with a positive speed limit of +5rpm.
Example of coiler operation:
This is an example of a coiler operating in the positive direction. The final speed demand is set to a positive value just above the coiler reference
speed. If the resultant torque demand is positive the coiler operates with a limited speed, so that if the material breaks the speed does not exceed a
level just above the reference. It is also possible to decelerate the coiler with a negative resultant torque demand. The coiler will decelerate down to -
5rpm until a stop is applied.

The operating area is shown in the following diagram:
Example of uncoiler operation:
This is an example for an uncoiler operating in the positive direction. The final speed demand should be set to a level just above the maximum normal
speed. When the resultant torque demand is negative the uncoiler will apply tension and try and rotate at 5rpm in reverse, and so take up any slack.
The uncoiler can operate at any positive speed applying tension. If it is necessary to accelerate the uncoiler a positive resultant torque demand is
used. The speed will be limited to the final speed demand. The operating area is the same as that for the coiler and is shown below:
4: Speed control with torque feed-forward
The drive operates under speed control, but a torque value may be added to the output of the speed controller. This can be used to improve the
regulation of systems where the speed loop gains need to be low for stability.
A first order filter, with a time constant defined by this parameter, is provided on the current demand to reduce acoustic noise and vibration produced
as a result of position feedback quantisation noise. The filter introduces a lag in the speed loop, and so the speed loop gains may need to be reduced
to maintain stability as the filter time constant is increased. Alternative time constants can be selected depending on the value of the speed controller
gain selector (Pr 3.16). If Pr 3.16 = 0 Pr 4.12 is used, if Pr 3.16 = 1 Pr 4.23 is used.

Open-loop
These parameters control the proportional and integral gains of the current controller used in the open loop drive. As already mentioned the current
controller either provides current limits or closed loop torque control by modifying the drive output frequency. The control loop is also used in its torque
mode during mains loss, or when the controlled mode standard ramp is active and the drive is decelerating, to regulate the flow of current into the
drive. Although the default settings have been chosen to give suitable gains for less demanding applications it may be necessary for the user to adjust
the performance of the controller. The following is a guide to setting the gains for different applications.
Current limit operation
The current limits will normally operate with an integral term only, particularly below the point where field weakening begins. The proportional term is
inherent in the loop. The integral term must be increased enough to counter the effect of the ramp which is still active even in current limit. For
example, if the drive is operating at constant frequency and is overloaded the current limit system will try to reduce the output frequency to reduce the
load. At the same time the ramp will try to increase the frequency back up to the demand level. If the integral gain is increased too far the first signs of
instability will occur when operating around the point where field weakening begins. These oscillations can be reduced by increasing the proportional
gain. A system has been included to prevent regulation because of the opposite actions of the ramps and the current limit. This can reduce the actual
level that the current limit becomes active by 12.5%. This still allows the current to increase up to the current limit set by the user. However the current
limit flag (Pr 10.09) could become active up to 12.5% below the current limit depending on the ramp rate used.
Torque control
Again the controller will normally operate with an integral term only, particularly below the point where field weakening begins. The first signs of
instability will appear around base speed, and can be reduced by increasing the proportional gain. The controller can be less stable in torque control
mode rather than when it is used for current limiting. This is because load helps to stabilise the controller, and under torque control the drive may
operate with light load. Under current limit the drive is often under heavy load unless the current limits are set at a low level.
Mains loss and controlled standard ramp
The DC bus voltage controller becomes active if mains loss detection is enabled and the drive supply is lost or controlled standard ramp is being used
and the machine is regenerating. The DC bus controller attempts to hold the DC bus voltage at a fixed level by controlling the flow of current from the
drive inverter into its DC bus capacitors. The output of the DC bus controller is a current demand which is fed into the current PI controller as shown
in the following diagram.
Although it is not usually necessary the DC bus voltage controller can be adjusted with Pr 5.31. However, it may often be necessary to adjust the
current controller gains to obtain the required performance. If the gains are not suitable it is best to set up the drive in torque control first. Set the gains
to a value that does not cause instability around the point at which field weakening occurs. Then revert back to open loop speed control in standard
ramp mode. To test the controller the supply should be removed while the motor is running. It is likely that the gains can be increased further if
required because the DC bus voltage controller has a stabilising effect, provided that the drive is not required to operate in torque control mode.

The proportional gain Kp (Pr 4.13) is the most critical value in controlling the performance of the current controllers. Either the value can be set by
auto-tuning (see Pr 5.12), or it can be set by the user so that
Kp = (L / T) x (Ifs / Vfs) x (256 / 5)
Where:
T is the sample time of the current controllers. The drive compensates for any change of sample time, and so it should be assumed that the
sample time is equivalent to the lowest sample rate of 167μs.
L is the motor inductance. For a servo motor this is half the phase to phase inductance that is normally specified by the manufacturer. For an
induction motor this is the per phase transient inductance (σLs). This is the inductance value stored in Pr 5.24 after the auto-tune test is carried
out.
Ifs is the peak full scale current feedback = Kc x √2 / 0.45. Where Kc is the current scaling for each size of drive.
Vfs is the maximum DC bus voltage.
Therefore:
Kp = (L / 167us) x (Kc x √2 / 0.45 / Vfs) x (256 / 5)
= K x L x Kc
Where:
K = √2 / (0.45 x Vfs x 167μs) x (256 / 5)
There is one value of the scaling factor K for each drive voltage rating as shown in the table below
The integral gain Ki (Pr 4.14) is less critical and should be set so that
Ki = Kp x 256 x T / τm
where
τm is the motor time constant (L / R).
R is the per phase stator resistance of the motor (i.e. half the resistance measured between two phases).
Therefore
Ki = (K x L x Kc) x 256 x 167us x R / L
= 0.0427 x K x R x Kc
The above equations give the gain values that are calculated by the auto-tune system and these should give the best response at all switching
frequencies with minimal overshoot. If required the gains can be adjusted to improve performance as follows:
1. The integral gain (Ki) can be used to improve the performance of the current controllers by reducing the effects of inverter non-linearity. These
effects become more significant with higher switching frequency. These effects will be more significant for drives with higher current ratings and
higher voltage ratings. If Ki is increased by a factor of 4 it is possible to get up to 10% overshoot in response to a step change of current
reference. For high performance applications, it is recommended that Ki is increased by a factor of 4 from the auto-tuned values. As the inverter
non-linearity is worse with higher switching frequencies it is may be necessary to increase Ki by a factor of 8 for operation with 16kHz switching
frequency.
2. It is possible to increase the proportional gain (Kp) to reduce the response time of the current controllers. If Kpi is increased by a factor of 1.5 then
the response to a step change of reference will give 12.5% overshoot. It is recommended that Ki is increased in preference to Kpi.
As already stated, the drive compensates for changes of switching frequency to give similar performance as the switching frequency changes. The
following table gives the relationship between the user gain values and the values actually used by the drive for Unidrive and Unidrive SP. Although
other scaling values are included in the current controller these values can be used to make a relative comparison between switching frequencies and
a relative comparison between Unidrive and Unidrive SP. For example: the amount of acoustic noise produced in the motor from encoder speed ripple
is generally related to the product of the speed controller and current controller proportional gains. The values in this table can be used in conjunction
with the speed loop proportional gain to assess the amount of acoustic noise that is likely to be produced from the encoder speed ripple for each
product and with different switching frequencies.

Regen
The defaults Kp and Ki gains should be suitable for the standard regen inductors. If the input inductance is significantly higher the gains should be
adjusted as described for the Closed-loop vector and Servo modes. See Pr 3.06 on page 85 for guidelines on setting the regen unit current controller
gains. The table given for the relative levels of current controller gains for closed-loop vector and servo modes also applies to regen mode.
The motor is modelled thermally in a way that is equivalent to the electrical circuit shown as follows.
The temperature of the motor as a percentage of maximum temperature, with a constant current magnitude of I, constant value of K and constant
value of motor rated current (set by Pr 5.07 or Pr 21.07) after time t is given by
Temp = [I2
/ (K x Motor rated current)2
] (1 - e-t/τ
) x 100%
This assumes that the maximum allowed motor temperature is produced by K x Motor rated current and that τ is the thermal time constant of the point
in the motor that reaches its maximum allowed temperature first. τ is defined by Pr 4.15. The estimated motor temperature is given by Pr 4.19 as a
percentage of maximum temperature. If Pr 4.15 has a value between 0.0 and 1.0 the thermal time constant is taken as 1.0.
If the rated current (defined by Pr 5.07 or Pr 21.07 depending on which motor is selected) is less or equal to the maximum Heavy Duty rating then
Pr 4.25 can be used to select 2 alternative protection characteristics (see diagram below). If Pr 4.25 is 0 the characteristic is for a motor which can
operate at rated current over the whole speed range. Induction motors with this type of characteristic normally have forced cooling. If Pr 4.25 is 1 the
characteristic is intended for motors where the cooling effect of motor fan reduces with reduced motor speed below half of rated speed. The maximum
value for K is 1.05, so that above the knee of the characteristics the motor can operate continuously up to 105% current. (In Regen mode K = 1.05
over the whole operating frequency range).

If the rated current is above the maximum Heavy Duty rating then Pr 4.25 can also be used to select 2 alternative protection characteristics. Both
characteristics are intended for motors where the cooling effect of the motor fan reduces with reduced motor speed, but with different speeds below
which the cooling effect is reduced. The maximum value for K is 1.01, so that above the knee of the characteristics the motor can operate
continuously up to 101% current. (In Regen mode K = 1.01 over the whole operating frequency range).
When the estimated temperature reaches 100% the drive takes some action depending on the setting of Pr 4.16. If Pr 4.16 is 0, the drive trips when
the threshold is reached. If Pr 4.16 is 1, the current limit is reduced to (K - 0.05) x 100% when the temperature is 100%. The current limit is set back
to the user defined level when the temperature falls below 95%. In servo and regen modes the current magnitude and the active current controlled by
the current limits should be similar, and so this system should ensure that the motor operates just below its thermal limit.
The time for some action to be taken by the drive from cold with constant motor current is given by:
Ttrip = -(Pr 4.15) x ln(1 - (K x Pr 5.07 / Pr 4.01)2
)
Alternatively the thermal time constant can be calculated from the trip time with a given current from:
Pr 4.15 = -Ttrip / ln(1 - (K / Overload)2
)
For example, if the drive should trip after supplying 150% overload for 60 seconds with K = 1.05 then
Pr 4.15 = -60 / ln(1 - (1.05 / 1.50)2) = 89

The thermal protection system can be used in regen mode to protect the input inductors. The rated current (Pr 5.07) should be set to the rated current
for the inductors.
The thermal model temperature accumulator is reset to zero at power-up and accumulates the temperature of the motor while the drive remains
powered-up. Each time Pr 11.45 is changed to select a new motor, or the rated current defined by Pr 5.07 or Pr 21.07 (depending on the motor
selected) is altered, the accumulator is reset to zero.
The drive reactive current is shown in this parameter for all modes.
The current limit applied at any time depends on whether the drive is motoring or regenerating and also on the level of the symmetrical current limit.

If this parameter is set to one, the drive calculates a torque reference from the motor and load inertia (Pr 3.18) and the rate of change of speed
reference. The torque reference is added to the speed controller output to provide inertia compensation. This can be used in speed or torque control
applications to produce the torque required to accelerate or decelerate the load inertia.
The current demand filter time constant is defined by this parameter if the speed gain select (Pr 3.16) is one.
* These are the maximum default values. If the variable maximum of this parameter (TORQUE_PROD_CURRENT_MAX which is defined by
MOTOR1_CURRENT_LIMIT_MAX or MOTOR2_CURRENT_LIMIT_MAX depending on which motor map is active) gives a lower value with the
default value of Motor rated current (Pr 5.07 or Pr 21.07) default of this parameter is at the lower value.

Open-loop
Although the range for scaling purposes is ±SPEED_FREQ_MAX, the actual parameter value can be increased beyond this range by slip
compensation. This parameter gives the output frequency of the drive, i.e. the sum of the post ramp reference and the slip compensation.
In these modes the output frequency is not controlled directly, and so the output frequency displayed in this parameter is calculated by measuring the
frequency of the controller reference frame.
Regen
In Regen mode the supply frequency is shown. Negative values indicate negative phase rotation of the supply.
This is the modulus of the r.m.s. line to line voltage at the inverter output at the drive output frequency.
Open-loop, Closed-loop vector and Servo modes
The output power is the dot product of the output voltage and current vectors. Positive power indicates power flowing from the drive to the motor
(motoring) and negative power indicates power flowing from the motor to the drive (regen).
Regen mode
The output power is the dot product of the output voltage and current vectors. Positive power indicates power flowing from the supply to the drive, and
negative power indicates power flowing from the drive to the supply.
The motor rpm is calculated from the post ramp reference (Pr 2.01) for normal operation, or the slave frequency demand (Pr 3.01) if frequency slaving
is being used. The speed of rotation is calculated as follows:
rpm = 60 x frequency / no. of pole pairs
This calculation relies on the number of motor poles being set up correctly in Pr 5.11, or if auto mode is selected (Pr 5.11 = 0) then it relies on a
reasonably accurate value of motor rated speed being set in Pr 5.08 to allow correct calculation of the motor poles. If frequency slaving is being used
there will be an error due to the slip frequency. However, in normal operation the result will be reasonably accurate provided that the slip
compensation has been set up correctly in the rated full load rpm parameter (Pr 5.08).

The motor rated frequency and the motor rated voltage (Pr 5.09) are used to define the voltage to frequency characteristic applied to the motor (see

Open loop
The rated load rpm is used with the motor rated frequency and No. of poles to calculate the rated slip of induction machines in Hz.
rated slip (Hz) = rated motor frequency - (no. of pole pairs x motor full load rpm / 60)
= Pr 5.06 - ((Pr 5.11 / 2) x Pr 5.08 / 60)
If Pr 5.08 is set to 0 or to synchronous speed slip compensation is disabled. If slip compensation is required this parameter should be set to the
nameplate value, which should give the correct rpm for a hot machine. Sometimes it will be necessary to adjust this when the drive is commissioned
because the nameplate value may be inaccurate. Slip compensation will operate correctly both below base speed and within the field weakening
region. Slip compensation is normally used to correct for the motor speed to prevent speed droop as load is applied. The rated load rpm can be set
higher than synchronous speed to deliberately introduce speed droop. This can be useful to aid load sharing with mechanically coupled motors.
Closed loop vector
Rated load rpm is used with motor rated frequency to determine the full load slip of the motor which is used by the vector control algorithm. Incorrect
setting of this parameter has the following effects:
• Reduced efficiency of motor operation
• Reduction of maximum torque available from the motor
• Reduced transient performance
• Inaccurate control of absolute torque in torque control modes
The nameplate value is normally the value for a hot machine, however, some adjustment may be required when the drive is commissioned if the
nameplate value is inaccurate. Either a fixed value can be entered in this parameter or the drive rated speed optimization system may be used to
automatically adjust this parameter (see Pr 5.16 on page 123). It should be noted that the optimization system does not operate when closed-loop
vector mode is used with no position feedback (see Pr 3.24 on page 64).
Servo
The Rated load rpm defines the rated speed of the motor and is only used in the motor thermal protection scheme (see Pr 4.16 on page 105). and to
determine the speed used in the auto tuning inertia test (see Pr 5.12 on page 117).
Open loop
The rated voltage is used in conjunction with the motor rated frequency (Pr 5.06) to define the voltage to frequency characteristic applied to the motor.
The following operating methods selected by Pr 5.14 are used to define the drive frequency to voltage characteristic.
Open-loop vector mode: Ur_S, Ur or Ur_I
A linear characteristic is used from 0Hz to rated frequency, and then a constant voltage above rated frequency. When the drive operates between
rated frequency/50 and rated frequency/4, full vector based stator resistance (Rs) compensation is applied. However there is a delay of 0.5s when the
drive is enabled during which only partial vector based compensation is applied to allow the machine flux to build up.

When the drive operates between rated frequency/4 and rated frequency/2 the Rs compensation is gradually reduced to zero as the frequency
increases. For the vector modes to operate correctly the stator resistance (Pr 5.17), motor rated power factor (Pr 5.10) and voltage offset (Pr 5.23) are
all required to be set up accurately.
Fixed boost mode: Fd
A linear characteristic is used from 0Hz to rated frequency, and then constant voltage above rated frequency. Low frequency voltage boost as defined
by Pr 5.15 is applied as shown below.
Square law mode: SrE
A square law characteristic is used from 0Hz to rated frequency, and then constant voltage above rated frequency. Low frequency voltage boost
raises the start point of the square law characteristic as shown below.
Closed loop vector
The rated voltage is used by the field controller to limit the voltage applied to the motor. Normally this is set to the nameplate value. So that current
control can be maintained it is necessary for the drive to leave some 'headroom' between the machine terminal voltage and the maximum available
drive output voltage. The drive allows over-modulation of the PWM inverter which can produce a fundamental voltage that is higher than the drive
input voltage, but would cause substantial odd harmonic distortion if used in steady state operation. Therefore the drive uses a headroom limit which
allows the inverter to give a steady state output voltage equivalent to the input voltage minus voltage drops inside the drive. This gives enough
headroom for the current controllers to operate satisfactorily. However, for good transient performance at high speed the rated voltage should be set
below 95% of the minimum supply voltage to the drive.
The rated voltage is also used in conjunction with the motor rated frequency (Pr 5.06) during the rotating auto-tune test (see Pr 5.12 on page 117) and
in the calculations required for automatic optimization of the rated motor slip. It is important, therefore that the correct rated voltage for the motor is
used. In some applications it may be necessary to restrict the voltage applied to the motor to a level lower than the nameplate rated voltage of the
motor. In this case the rated frequency (Pr 5.06) must be adjusted to maintain the ratio of rated voltage and frequency given on the motor nameplate.
The rated frequency will then be different to the nameplate value, and so the rated speed must be changed from the nameplate value to give the
correct rated slip.
Servo
The rated voltage is used by the field controller to limit the voltage applied to the motor if high speed operation is required. As in closed-loop vector
mode some headroom must be left for the current controllers to operate, and so the drive will use the voltage level set by this parameter or the
headroom limit whichever is the lower.

Open loop
The power factor is the true power factor of the motor, i.e. the angle between the motor voltage and current. The power factor is used in conjunction
with the motor rated current (Pr 5.07) to calculate the rated active current and magnetising current of the motor. The rated active current is used
extensively to control the drive, and the magnetising current is used in vector mode Rs compensation. It is important that this parameter is set up
correctly.
Closed loop vector
The power factor is the true power factor of the motor, i.e. the angle between the motor voltage and current. If the stator inductance is set to zero (Pr
5.25) then the power factor is used in conjunction with the motor rated current and other motor parameters to calculate the rated active and
magnetising currents which are used in the vector control algorithm. If the stator inductance has a non-zero value this parameter is not used by the
drive, but is continuously written with a calculated value of power factor
Open-loop
This parameter is used in the calculation of motor speed and in applying the correct slip compensation. When auto is selected the number of motor
poles is automatically calculated from the rated frequency (Pr 5.06) and the rated load rpm (Pr 5.08). The number of poles = 120 * rated frequency /
rpm rounded to the nearest even number.
Closed-loop vector
This parameter must be set correctly for the vector control algorithms to operate correctly. When auto is selected the number of motor poles is
automatically calculated from the rated frequency (Pr 5.06) and the rated load rpm (Pr 5.08). The number of poles = 120 * rated frequency / rpm
rounded to the nearest even number.
Servo
This parameter must be set correctly for the vector control algorithms to operate correctly. When auto is selected the number of poles is set to 6.
If this parameter is set to a non-zero value, the drive is enabled and a run command is applied in either direction the drive performs an auto-tune test
for the drive modes listed below. All tests that rotate the motor are carried out in the forward direction if Pr 1.12 = 0 or the reverse direction if Pr 1.12
= 1. For example, if the test is initiated by applying run reverse (Pr 6.32 = 1) the test is performed in the reverse direction. It should be noted however
that the motor may jump in either direction by up to half an electrical revolution at the start of the phasing test and then move in the required direction
for the remainder of the test. The test will not start unless the drive is disabled before the test is initiated by applying the enable or run, i.e. it will not
start if the drive is in the stop state. In closed-loop modes it is not possible to go into the stop state if Pr 5.12 has a non-zero value.

(If Pr 5.12 is set to 4 in closed-loop vector mode or 6 in servo mode then no test is carried out, but the current loop gains are re-calculated. For these
actions the drive does not need to be enabled).
It is important that the motor is at standstill before the auto-tune test is performed if the correct results are to be obtained. The parameters modified by
the auto-tune tests are defined below when the second motor parameters are not selected (i.e. Pr 11.45 = 0). If the second motor is selected for the
duration of the tests (i.e. Pr 11.45 = 1), the second motor parameters in menu 21 are modified instead and not the parameters described below. When
the test is completed successfully the drive is disabled and will enter the inhibit state. The motor can only be restarted if the enable is removed either
from the enable input, or Pr 6.15 is set to zero or from the control word (Pr 6.42). As the tests progresses the calculated parameters are saved to
EEPROM as indicated. If for any reason the test fails, and the drive trips, no further parameters are calculated or stored in EEPROM. (If the drive is in
Auto or Boot copying modes (Pr 11.42 = 3 or 4) the parameters are also saved to the SMARTCARD where it is indicated that parameters are saved
to EEPROM).
Open-loop
In this mode the following parameters are used in the vector control algorithm.
All these parameters can be set by the user. The auto-tune test can be used to overwrite the user or default settings as described below. Accurate
values of stator resistance and voltage offset are required even for moderate performance in vector mode (an accurate value of power factor is less
critical).
1: Stationary test
• A stationary test is performed to measure the stator resistance (Pr 5.17) and voltage offset (Pr 5.23). The power factor (Pr 5.10) is not affected.
• Pr 5.17 and Pr 5.23 are saved to EEPROM.
2: Rotating test
• The stationary test is performed and the parameters saved to EEPROM as described above.
• A stationary test is performed to measure the transient inductance (Pr 5.24). The transient inductance is not used directly by the drive, but is an
intermediate value in determining the power factor after the rotating test.
• Pr 5.24 is saved to EEPROM.
• A rotating test is performed in which the motor is accelerated with the currently selected ramps to 2
/3 of rated speed and held at this speed for
several seconds. Once the test is complete the power factor (Pr 5.10) is updated and the motor coasts to a stop. The motor should be unloaded
for this test to produce correct results.
Closed-loop vector
All these parameters can be set by the user. The motor set-up is constantly recalculated in the background task, therefore modifying these
parameters even after auto-tune will affect the performance of the drive. The auto-tune test can be used to overwrite the user or default settings as
described below. It should be noted that the current loop gains (Pr 4.13 and 4.14) are not updated as part of any test if either the stator resistance or
the transient inductance for the active motor map are zero.

1. Stationary test
• A stationary test is performed to measure the stator resistance (Pr 5.17)
• A stationary test is performed to measure the transient inductance (Pr 5.24). When this test is complete the current loop gains (Pr 4.13 and Pr
4.14) are over-written with the correct values based on the calculations given in Menu 4. A moderately accurate value of ϕ1 as described in menu
4 can be obtained from the measured stator resistance and transient inductance to set the correct current limits and flux level in the motor.
• Pr 4.13, Pr 4.14 and Pr 5.24 are saved to EEPROM.
2. Rotating test
• The stationary tests are performed and the parameters saved to EEPROM as described above.
• A rotating test is performed in which the motor is accelerated using the ramp rate defined by Pr 2.11 (or Pr 21.04 if motor 2 is selected) to 2
/3 of
rated frequency and held at this frequency for up to 36 seconds. During the rotating test the stator inductance (Pr 5.25), and the motor saturation
breakpoints (Pr 5.29 and Pr 5.30) are calculated. The power factor is also modified for user information only, and is not used after this point
because the stator inductance will have a non-zero value. When the test is complete the motor coasts to a stop. The motor should be unloaded
for this test to produce correct results.
3. Inertia measurement
• The drive attempts to accelerate the motor in the forward direction up to 3
/4 x rated load rpm and then back to standstill. Several attempts may be
made, starting with rated torque/16, and then increasing the torque progressively to x1
/8, x1
/4, x1
/2 and x1 rated torque if the motor cannot be
accelerated to the required speed. 5s acceleration time is allowed during the first four attempts and 60s on the final attempt. If the required speed
is not achieved on the final attempt the test is aborted and a tuNE1 trip is initiated. If the test is successful the acceleration and deceleration times
are used to calculate the motor and load inertia which is written to Pr 3.18. (If closed-loop vector control without position feedback is used the first
attempt is made with x1/4 because the torque control at very low speeds is not as accurate as when position feedback is used. Using a higher
level of torque ensures that the motor starts).
The calculated value of inertia is dependant on the value of the motor torque per amp parameter (Pr 5.32) which is calculated by the drive using an
efficiency of 0.9. Therefore the inertia may be inaccurate if the motor efficiency is substantially different from 0.9. However, if the inertia is used for
automatic speed loop gain set up the calculated gains will not be affected because Kt is also used in these calculations and any inaccuracy cancels
out.
The test algorithm attempts to remove the effect of any load on the motor other than the torque required to accelerate and decelerate the motor, i.e.
friction and windage losses, static torque load etc. Provided the average torque during acceleration and the average torque during deceleration are
the same the effect of the additional torque is removed and the inertia value is calculated correctly.
4. Current controller gain calculation only
• No current is applied to the motor.
• The current loop gains are calculated based on the value of the motor inductance (Pr 5.24) and resistance (Pr 5.17) and written to Pr 4.13 and
Pr 4.14.
This is intended to be used as a method of setting up the current loop gains from user defined values of motor inductance and resistance. The drive
should not be enabled to perform these calculations. If the parameter is set to 4 it is automatically cleared by the drive once the calculation is
complete. It should be noted that the value changes back to zero within a few hundred milliseconds of being set to 4 by the user.
Servo
All these parameters can be set by the user. The motor set-up is constantly recalculated in the background task, therefore modifying these
parameters even after auto-tune will affect the performance of the drive. The auto-tune test can be used to overwrite the user or default settings as
described below. It should be noted that the current loop gains (Pr 4.13 and Pr 4.14) are not updated as part of any test if either the stator resistance
or the transient inductance for the active motor map are zero.
1: Short low speed test
• The motor is rotated by 2 electrical revolutions (i.e. up to 2 mechanical revolutions) in the forward direction. The drive applies rated current to the
motor during the test and measures the encoder phase angle (Pr 3.25) only. The phase angle measurement is taken when the motor has stopped
at the end of the test, therefore there must be no load on the motor when it is at rest for the correct angle to be measured. This test takes
approximately 2 seconds to complete and can only be used where the rotor settles to a stable position in a short time.

2. Normal low speed test
• The motor is rotated by 2 electrical revolutions (i.e. up to 2 mechanical revolutions) in the forward direction. The drive applies rated current to the
motor during the test and measures the encoder phase angle (Pr 3.25). The phase angle measurement is taken when the motor has stopped at
the end of the test, therefore there must be no load on the motor when it is at rest for the correct angle to be measured.
• A stationary test is performed to measure the motor resistance (Pr 5.17).
• A stationary test is performed to measure the motor inductance (Pr 5.24). When this test is complete the current loop gains (Pr 4.13 and Pr 4.14)
are over-written with the correct values based on the calculations given in Menu 4. It should be noted that the inductance measured is the
inductance in the flux axis. For many motors this will be 20 to 30% less that the inductance in the other axis. The inductance for the other axis
could be used to calculate the current controller proportional gain if required because there are no transient changes of current reference flux
axis. Therefore the gain can be increased by the user if required. The inductance for the other axis should be used to obtain optimal cross
coupling cancellation (see Pr 5.26 on page 128), and so the inductance parameter (Pr 5.24) could also be increased by the user if required.
The whole test takes approximately 20 seconds and can be used with motors that take time to settle after the rotor has moved. During the motor
inductance measurement the drive applies current pulses to the motor that produces flux that opposes the flux produced by the magnets. The
maximum current applied is a quarter of rated current (Pr 5.07 or Pr 21.07). This current is unlikely to affect the motor magnets, however, if this level
of current could permanently de-magnetise the magnets the rated current should be set to a lower level for the tests to avoid this.
Either the short or normal low speed tests could be used with a servo motor that does not have an absolute encoder (i.e. incremental without UVW
commutation signals, SINCOS without comms etc). to control a servo motor. A phasing test would need to be performed after each power-up, or loss
of encoder power supply if the motor rotates while the supply is not present before the motor could be controlled by the drive. If this method of control
is used the drive cannot do any error checking to ensure that the absolute position has not been lost due to unwanted encoder counts due to noise.
Either the short or the normal low speed tests can be used with a servo type encoder (Ab.Servo, Fd.Servo or Fr.Servo) that has only commutation
signals, i.e. the lines per revolution has been set to zero. When these tests are performed with this type of encoder the motor will continue to move in
the same direction after the first two electrical revolutions. It will then stop for either 0.8s (short test) or 4s (normal test) and then continue to move
again for part of an electrical revolution.
3: Inertia measurement
See inertia test for closed-loop vector mode. The calculated inertia depends on the value of motor torque per amp entered in Pr 5.32. If this parameter
is incorrect the inertia value will be incorrect. However, as explained in the inertia test description for closed-loop vector mode, this will not affect the
accuracy of automatic speed loop gain set up.
4. Stationary test to set up current controller gains only
• A stationary test is performed to measure the motor resistance (Pr 5.17).
• A stationary test is performed to measure the motor inductance (Pr 5.24). When this test is complete the current loop gains (Pr 4.13 and Pr 4.14)
are overwritten with the correct values based on the calculations given in Menu 4.
This test can only be used with a motor when the correct phasing angle has been set in Pr 3.25, because rated current is applied in the flux axis
during the resistance measurement. If the phasing angle is not correct the motor may move and the results may be incorrect.
5. Minimal movement phasing test
Short current pulses are applied to the motor to produce a small movement and then to move the motor back to the original position. The size and
length of the pulses are gradually increased (up to a maximum of rated current defined by Pr 5.07) until the movement is approximately at the level
defined by Pr 5.38 electrical degrees.. The resulting movements are used to estimate the phase angle. The test is carried out as follows:
• Current pulses are applied to determine the phasing angle
• An additional test is performed to ensure that the phasing angle is correct. If the test fails there is a delay and then test recommences. This is
repeated twice after which a tunE2 trip is initiated. The delay before recommencing the test is 200ms and then 400ms. These delays allow the
motor to stop moving if the test has initiated movement due to cogging torque.
• A test is performed to ensure that the feedback device direction is correct
• Pr 3.25 (phasing angle) is updated and saved to EEPROM.
This test will operate correctly when the load is an inertia, and although a small amount of cogging and stiction is acceptable, this test cannot be used
for a loaded motor. The test can only be used where the total inertia is less than 0.715 x Trated / Pr 5.38 kgm2
, assuming no additional stictional load,
where Trated is the torque produced by rated current as defined by Pr 5.07 or Pr 21.07. In most cases the motor only moves by the required angle,
however, it is possible for the test to initiate additional movement due to cogging torque. The amount of movement depends on the design of the
motor and is similar to the movement produced by cogging torque when the drive is disabled. If the motor is moving at a speed that is higher than the
zero speed threshold (Pr 3.05) when the test is initiated a tunE3 trip is initiated.
This test can be used with any type of encoder except a commutation only encoder i.e. Ab.Servo, Fd.Servo or Fr.Servo encoders with the lines per
rev set to zero. However, it is also not recommended with Ab.Servo, Fd.Servo or Fr.Servo encoders because the absolute position is not defined until
two valid changes of the commutation signals have occurred after power-up or an encoder trip. Therefore if the test is carried out before two valid
changes have occurred, the movement produced during the test may be quite large and the result may be slightly inaccurate. Once two valid changes
have occurred the test operates in the same way as for other encoder types.

The current controllers are used to perform this test, however, the default gains may be too high. It is not possible to carry out the necessary test to
set up the current controllers before the phasing angle is known. If the gains are too high the minimal movement phasing test may cause an OI.AC
trip. If this happens the current controller gains should be reduced progressively until the test is successful. Once the phasing angle is known, the
stationary test to set up the current controller gains only (Pr 5.12 = 4) may be used to obtain the correct gain values for the current controllers.
6. Current controller gain calculation only
• No current is applied to the motor.
• The current loop gains are calculated based on the value of the motor inductance (Pr 5.24) and resistance (Pr 5.17) and written to Pr 4.13 and
Pr 4.14.
This is intended to be used as a method of setting up the current loop gains from user defined values of motor inductance and resistance. The drive
should not be enabled to perform these calculations. If the parameter is set to 6 it is automatically cleared by the drive once the calculation is
complete. It should be noted that the value changes back to zero within a few hundred milliseconds of being set to 6 by the user.
The auto-tune tests may be aborted by removing the run command or the enable or if a trip occurs. During the auto-tune tests the following trips can
occur in addition to the other drive trips.
*The rS trip is produced if the drive cannot achieve the necessary current levels to measure the stator resistance during the test (i.e. there is no motor
connected to the drive), or if the necessary current level can be achieved, but the calculated resistance exceeds the maximum values for the
particular drive size or it exceeds the maximum of Pr 5.17. The maximum measurable value for a particular drive size can be calculated from the
following formula.

Setting this bit enables dynamic V to f mode which is intended for applications where power loss should be kept to a minimum under low load
conditions. The rated frequency used to derive the voltage to frequency characteristic of the drive is varied with load:
if |active current| < 0.7 x rated active current
motor rated frequency = Pr 5.06 x (2 - (active current / (0.7 x rated active current)))
else if |active current| ≥ 0.7 x rated active current
motor rated frequency = Pr 5.06
Although the rated frequency varies the value shown as Pr 5.06 does not vary from that set by the user.
Closed-loop vector
At light load the losses in the motor can be reduced by reducing the motor flux. When flux optimization is selected the flux producing current in the
motor is reduced under light load conditions so that it is equal to the torque producing current with a minimum limit of half the rated flux producing
current. This optimizes the copper losses in the motor and reduces the iron losses.Flux optimization is disabled if closed-loop vector mode is used
without position feedback (i.e. Pr 3.24 is set to 1 or 3).
0: Ur_S, Stator resistance and voltage offset measured at each start
The stator resistance (Pr 5.17) and the voltage offset (Pr 5.23) are measured and the parameters over-written each time the drive is started. This test
can only be done with a stationary machine where the flux has decayed to zero. Therefore this mode should only be used if the machine is
guaranteed to be stationary each time the drive is enabled. To prevent the test from being done before the flux has decayed there is a period of 1
second after the drive has been in the ready state during which the test is not done if the drive is re-started. In this case, previously measured values
are used. The new values of stator resistance and voltage offset are not automatically saved to EEPROM or the SMARTCARD.
1: Ur, No measurements
The stator resistance and voltage offset are not measured. The user can enter the motor and cabling resistance into the stator resistance parameter.
However this will not include resistance effects within the drive inverter. Therefore if this mode is to be used, it is best to use the auto-tuning stationary
test initially to measure the stator resistance.
2: Fd, Fixed boost mode.
Neither the stator resistance nor the voltage offset are used, instead a fixed characteristic with boost applied as defined by Pr 5.15 is used.
3: Ur_Auto, Stator resistance and voltage offset measured at first drive enable
The stator resistance and voltage offset are measured once, the first time the drive is enabled. After the test has been completed successfully the
mode is changed to Ur mode. The stator resistance and voltage offset are written to the parameters for the currently selected motor map and these
parameters along with this parameter are saved in the EEPROM (and the SMARTCARD if Pr 11.42 = 3 or 4). If the test fails the stator resistance and
voltage offset are not updated, the mode is changed to Ur, but no parameters are saved.
4: Ur_I, Stator resistance and voltage offset measured at each power-up
The stator resistance and voltage offset are measured when the drive is first enabled and at each subsequent power-up. The new values of stator
resistance and voltage offset are not automatically saved to EEPROM or the SMARTCARD.
5: SrE, Square law characteristic
Neither the stator resistance nor the voltage offset are used, instead a fixed square law characteristic with boost applied as defined by Pr 5.15 is used.

This parameter defines the action taken on enable as follows:
0: nonE
No action.
1: Ph Enl
A minimal movement phasing test is performed each time the drive is enabled (i.e. changes from the inhibit state to either the stop or run state). The
test can be used to determine the phasing angle for an absolute or non-absolute type encoder. If the test is completed successfully the drive changes
to the stop or run state as appropriate. The phasing angle parameter is updated to the correct value, but it is not saved to EEPROM or the SMART
card.
2: Ph Init
A minimal movement phasing test is performed the first time the drive is enabled after power-up. The test will only be performed again on enable if the
position feedback device(s) have been re-initialized. Re-initialization occurs for example after a trip specifically related to an encoder where position
information may have been lost. Initialization occurs when parameter 03.48 changes from zero to one. The phasing angle parameter is updated to the
correct value, but it is not saved to EEPROM or the SMART card.
The voltage boost is used in fixed boost mode and square law mode for Open-loop mode, and during the rotating auto-tune test in Closed-loop vector
mode.In open-loop mode the default is dependant on the frame size as given in the table below.
The motor rated full load rpm parameter (Pr 5.08) in conjunction with the motor rated frequency parameter (Pr 5.06) defines the full load slip of the
motor. The slip is used in the motor model for closed-loop vector control. The full load slip of the motor varies with rotor resistance which can vary
significantly with motor temperature. When this parameter is set to 1 or 2 the drive can automatically sense if the value of slip defined by Pr 5.06 and
Pr 5.08 has been set incorrectly or has varied with motor temperature. If the value is incorrect Pr 5.08 is automatically adjusted. Pr 5.08 is not saved
at power-down, and so when the drive is powered-down and up again it will return to the last value saved by the user. If the new value is required at
the next power-up it must be saved by the user. Automatic optimization is only enabled when the frequency is above rated frequency/8, and when the
load on the motor load rises above 5
/8 rated load. Optimization is disabled again if the load falls below half rated load. For best optimization results the
correct values of stator resistance (Pr 5.17), transient inductance (Pr 5.24), stator inductance (Pr 5.25) and saturation breakpoints (Pr 5.29 and Pr
5.30) should be stored in the relevant parameters. Rated rpm auto-tune is not available if the drive is not using external position/speed feedback
(RFC mode).
The gain of the optimizer, and hence the speed with which it converges, can be set at a normal low level when Pr 5.16 is set to 1. If this parameter is
set to 2 the gain is increased by a factor of 16 to give faster convergence.
The rated rpm optimizer is automatically disabled when closed-loop vector RFC mode is selected (Pr 3.24=1 or 3).

Pr 5.17 shows the stator resistance of the motor. The units vary with the drive size to ensure that the full range of likely resistances can be
represented with suitable resolution. The table below shows the units. Therefore 1.000 in the parameter represents the resistance shown in the units
column.
From software version 1.07.00 onwards the maximum value of this parameter increased from 30 to 65 ohms to allow use of the autotune with very
small motors. rS trips will be seen with small motors with a higher resistance than 30 ohms per phase with earlier software versions.
*The maximum switching frequency available is limited for some drive sizes as shown in the table below.

This parameter defines the required switching frequency. The drive may automatically reduce the actual switching frequency (without changing this
parameter) if the power stage becomes too hot. The switching frequency can reduce from 12kHz to 6kHz to 3kHz, or 16kHz to 8kHz to 4kHz. An
estimate of the IGBT junction temperature is made based on the heatsink temperature and an instantaneous temperature drop using the drive output
current and switching frequency. The estimated IGBT junction temperature is displayed in Pr 7.34. If the temperature exceeds 135°C the switching
frequency is reduced if this is possible (i.e >4kHz) and this mode is enabled (see Pr 5.35 on page 131). Reducing the switching frequency reduces the
drive losses and the junction temperature displayed in Pr 7.34 also reduces. If the load condition persists the junction temperature may continue to
rise. If the temperature exceeds 145°C and the switching frequency cannot be reduced the drive will initiate an O.ht1 trip. Every 20ms the drive will
attempt to restore the switching frequency if the higher switching frequency will not take the IGBT temperature above 135°C.
The following table gives the sampling rate for different sections of the control system for different switching frequencies.

Normally the drive will use space vector modulation to produce the IGBT control signals. High stability space vector modulation offers three
advantages in an open loop drive, but the acoustic noise produced by the motor may increase slightly.
• It is possible for instability to occur around motor rated frequency/2 on light load. The drive uses dead-time compensation to reduce this effect,
however, it is still possible that some machines will be unstable. To prevent this, high stability space vector modulation should be enabled by
setting this parameter.
• As the output voltage approaches the maximum available from the drive pulse deletion occurs. This can cause unstable operation with a lightly or
fully loaded machine. High stability space vector modulation will reduce this effect.
• High stability space vector modulation also gives a small reduction in drive heat loss.
Open loop
The maximum modulation level of the drive is normally limited to unity giving an output voltage equivalent to the drive input voltage minus voltage
drops within the drive. If the motor rated voltage is set at the same level as the supply voltage some pulse deletion will occur as the drive output
voltage approaches the rated voltage level. If Pr 5.20 is set to 1 the modulator will allow over modulation, so that as the output frequency increases
beyond the rated frequency the voltage continues to increase above the rated voltage. The modulation depth will increase beyond unity; first
producing trapezoidal and then quasi-square waveforms. This can be used for example to obtain high output frequencies with a low switching
frequency which would not be possible with space vector modulation limited to unity modulation depth. The disadvantage is that the machine current
will be distorted as the modulation depth increases above unity, and will contain a significant amount of low order odd harmonics of the fundamental
output frequency.
As the rated voltage parameter is increased for a given d.c. link voltage the modulation depth is also increased. Therefore if the rated voltage is set to
a level higher than the supply voltage the point at which pulse dropping, over-modulation and quasi-square operation each begin may occur at a
frequencies below the rated frequency.
A suitable field controller gain is automatically set by the drive from the motor parameters. However it is possible by setting this parameter to a 1 to
reduce this gain by a factor of 2 if instability problems occur above base speed.

High speed servo mode is not enabled as default. Care must be taken when using this mode with servo motors to avoid damaging the drive. The
voltage produced by the servo motor magnets is proportional to speed. For high speed operation the drive must apply currents to the motor to
counter-act the flux produced by the magnets. It is possible to operate the motor at very high speeds that would give a very high motor terminal
voltage, but this voltage is prevented by the action of the drive. If however, the drive is disabled (or tripped) when the motor voltages would be higher
than the rating of the drive without the currents to counter-act the flux from the magnets, it is possible to damage the drive. If high speed mode is
enabled the motor speed must be limited to the levels given in the table below unless an additional hardware protection system is used to limit the
voltages applied to the drive output terminals to a safe level.
Ke is the ratio between r.m.s. line to line voltage produced by the motor and the speed in V/1000rpm. Care must also be taken not to de-magnetize
the motor. The motor manufacturer should always be consulted before using this mode.
Due to various effects in the drive inverter a voltage offset must be produced before any current flows. To obtain good performance at low frequencies
where the machine terminal voltage is small this offset must be taken into account. The value shown in Pr 5.23 is this offset given in line to line rms
volts. It is not possible for the user to measure this voltage easily, and so the automatic measurement procedure should be used (see Pr 5.14 on page
122).

With reference to the diagram below, the transient inductance is defined as
σLs = L1 + (L2.Lm / (L2 + Lm))
Based on the parameters normally used for the motor equivalent circuit for transient analysis, i.e. Ls = L1 + Lm, Lr = L2 + Lm, the transient inductance
is given by
σLs = Ls - (Lm
2 / Lr)
The transient inductance is used as an intermediate variable to calculate the power factor in open-loop mode. It is used in the vector algorithm, for
cross-coupling compensation and to set the current controller gains in closed-loop vector mode.
Servo
The transient inductance is the phase inductance for a servo motor. This is half the inductance measured from phase to phase. This value is used for
cross-coupling compensation and to set the current controller gains.
This parameter holds the stator inductance of the motor with rated flux. If the motor flux is reduced the value of stator inductance used by the vector
control algorithm is modified using the motor saturation breakpoints (Pr 5.29 and Pr 5.30). Stator inductance (Ls) = L1 + Lm from the steady state
equivalent circuit. It should be noted that if this parameter is changed from a non-zero value to zero the power factor (Pr 5.10) is automatically set to
0.850. The same applies to the motor map 2 stator inductance (Pr 21.24) and motor map 2 power factor (Pr 21.10).
When this bit is set the drive provides a cross-coupling feed forward voltage as produced by the transient inductance and a frequency based voltage
feed forward term. These voltages improve the transient performance of the current controllers

The level of slip compensation is set by the rated frequency and rated speed parameters. Slip compensation is only enabled when this parameter is
set to 1 and Pr 5.08 is set to a value other than zero or synchronous speed.
When the flux in the motor is reduced below its rated level the level of torque producing current required for a given amount of shaft torque is higher
than the rated level. In speed control the compensation prevents gain reduction at higher speeds. In torque control the compensation maintains the
torque at the correct level for a given torque demand. In some applications using speed control it may be desirable to have a reduction of gain as the
motor flux is reduced to maintain stability. If this is required Pr 5.28 should be set to one. It should be noted that although field weakening is possible
in servo mode, gain compensation is not applied in this mode.
The rated level of flux in most induction motors causes saturation. Therefore the flux against flux producing current characteristic is non-linear. The
effects of saturation are to cause a step increase in torque when operating in torque mode as the speed increases into the field weakening region.

The drive can include the effects of saturation by representing the flux producing current to flux characteristic as a series of three lines as shown
below:
If Pr 5.29 and Pr 5.30 have their default values of 50 and 75, the characteristic becomes one line and there will be a linear relationship between the
drive estimate of flux and the flux producing current. If Pr 5.29 and Pr 5.30 are increased above 50 and 75 the drive estimate of flux can include the
effect of saturation. It is unlikely that information will be available to set up these parameters, and so the values are determined during the rotating
auto-tune test.
This parameter controls the gain of the voltage controller used for mains loss and standard ramp control. If the parameter is set to 1 the gain used is
suitable for applications where the drive is used alone. Higher values are intended for applications where the DC bus of each drive is connected in
parallel and the drive is used as a master for mains loss control. This is intended for use in applications where each drive is locked together using
open-loop frequency slaving. (If motors are locked together using digital-locking, using a master for mains loss control, it is unlikely that the system
will be stable during mains loss unless the power rating of the master is much higher than the combined rating of the slaves. This is due to the lag
created by the master motor inertia).
This parameter shows the motor torque per amp of active (torque producing) current used to calculate the speed controller gains when the automatic
set-up methods are active (i.e. Pr 3.17 = 1 or 2).
Closed-loop vector
The drive calculates the motor torque per amp of active current using the motor parameters as shown below assuming a motor efficiency of 90%.
Rated active current is the active current when the motor current is equal to the rated motor current and is defined at the start of the description of
menu 4.
Servo
The motor torque per amp (Kt) must be entered in this parameter by the user for the automatic gain calculation system to operate correctly, and to
allow the drive to calculate the correct inertia during an inertia auto-tune.

This parameter is used to set up the current controller integral terms when the drive is disabled to prevent current transients when the drive is enabled
with a spinning motor. It is also used to provide a voltage feed forward term if high dynamic performance is selected with Pr 5.26.
The drive thermal protection scheme (see Pr 5.18 on page 124) reduces the switching frequency automatically when necessary to prevent the drive
from overheating. It is possible to disable this feature by setting this bit parameter to one. If the feature is disabled the drive trips immediately when
the IGBT temperature is too high.
This parameter should be set up to give the pole pitch of a linear motor, i.e. the movement of the motor for one cycle of the drive power output
waveforms, if auto-configuration with a linear EnDat encoder is required.

Pr 5.37 shows the actual switching frequency used by the inverter. The maximum switching frequency is set with parameter Pr 5.18, but this may be
reduced by the drive if automatic switching frequency changes are allowed (Pr 5.35=1). Pr 5.37 also indicates if the sample time for the current
controllers have been reduced to allow for SINCOS encoders with lines per revolution that are not a power of two, or closed-loop vector mode
operation without an encoder.
By applying short current pulses to the motor and using the resulting movement the drive can calculate the phasing angle (Pr 3.25 or Pr 21.20). These
begin at as short low level pulses, which are increased in magnitude and length until the required electrical movement define by Pr 5.38 is achieved.
The actual movement may be larger because motor cogging may cause additional unwanted movement. The required movement should only be
reduced if this is necessary as the results become less accurate with less movement. Care should be taken to ensure that the minimum movement is
large enough so that the change of position given by the feedback device can be registered by the drive. For example a 4096 line incremental device
on a 6 pole motor will give a change of position count of 75 for a 5°electrical movement. It is suggested that this test should not be used with a change
of position count of less than 50. Although Pr 5.38 can be reduced to zero the lowest value used by the drive is 1.0 degrees.
The necessary movement can be produced with a lower torque level if the test pulses are extended. If the pulses of torque are smaller then the
acceleration is less, and so the noise and vibration produced by the test are less. The pulse length can be modified with Pr 5.39 (1 = pulse lengths x
2, 2 = x 3, and 3 = x 4). Longer pulses should only be used if noise and vibration are a problem and the motor has low friction and low cogging torque.
As the torque level is reduced the measurement is likely to be affected by cogging and the results may not be accurate.

If Pr 6.09 is set to enable the catch a spinning motor function in open-loop mode or closed-loop vector mode without position feedback (RFC mode)
(Pr 3.24 = 1 or 3) this parameter defines a scaling function used by the algorithm that detects the speed of the motor. It is likely that for smaller motors
the default value of 1.0 is suitable, but for larger motors this parameter may need to be increased. If the value of this parameter is too large the motor
may accelerate from standstill when the drive is enabled. If the value of this parameter is too small the drive will detect the motor speed as zero even
if the motor is spinning.

Stopping is in two distinct phases: decelerating to stop, and stopped.
Once modes 3 or 4 have begun the drive must go through the ready state before being restarted either by stopping, tripping or being disabled.
If this parameter is set to 5 (Disable stopping mode) the disable stopping mode is used when the run command is removed and will allow the drive to
be started immediately by reapplying the run command. However, if the drive is disabled by removing the drive enable (i.e. via the secure disable
input or the drive enable (Pr 6.15)) then the drive cannot be re-enabled for 1s.
Only one stopping phase exists and the ready state is entered as soon as the single stopping action is complete. It should be noted that the stop
condition is detected when the speed feedback is below the zero speed threshold (Pr 3.05) for at least 16ms. If the speed is not stable it is possible
that the stop condition is not detected. In this case the system should be made more stable or the zero speed threshold should be raised.
If coast stop is selected the inverter is inhibited immediately when the run command is removed. If however, hold zero speed is also selected (Pr 6.08
= 1), then the inverter will be re-enabled to hold zero speed. The result is that the inverter is disabled for one sample and then enabled to ramp the
motor to a stop. Therefore is coast stop is required Pr 6.08 should be set to zero to disable hold zero speed.
If stop with ramp is selected the relevant ramp rate is used to stop the motor even if Pr 2.02 is set to zero to disable ramps.
The motor can be stopped with position orientation after stopping. This mode is selected with the position controller mode (Pr 13.10). When this mode
is selected Pr 6.01 has no effect.

There is no mains loss detection and the drive operates normally only as long as the DC bus voltage remains within specification (i.e. >Vuu). Once

mode to stop on loss of the supply. If ramp stop followed by injection braking is selected, the drive will ramp to a stop and then attempt to apply DC
injection. If the main is reapplied the drive restarts after it reaches the ready state provided the necessary controls are still active to initiate a start.
Closed-loop vector or Servo
The speed reference is set to zero and the ramps are disabled allowing the drive to decelerate the motor to a stop under current limit. If the mains is
re-applied while the motor is stopping any run signal is ignored until the motor has stopped. If the current limit value is set at a very low level the drive
may trip UU before the motor has stopped. If the mains is reapplied the drive restarts after it reaches the ready state provided the necessary controls
are still active to initiate a start.
2: ride.th
The drive detects mains loss when the DC bus voltage falls below Vml1. The drive then enters a mode where a closed-loop controller attempts to hold
the DC bus level at Vml2. This causes the motor to decelerate at a rate that increases as the speed falls. If the mains is re-applied it will force the DC
bus voltage above the detection threshold Vml3 and the drive will continue to operate normally. The output of the mains loss controller is a current
demand that is fed into the current control system and therefore the gain parameters Pr 4.13 and Pr 4.14 must be set up for optimum control. See
Pr 4.13 and Pr 4.14 on page 103 for set-up details.
The following table shows the voltage levels used by drives with each voltage rating.
* Vml1 is defined by Pr 6.48. The values given in the table are the default values.
This parameter is provided to allow the user to select several predefined digital input routing macros to control the sequencer. When a value between
0 and 3 is selected, the drive processor continuously updates the destination parameters for digital I/O T25, T26 and T27, and the enable sequencer
latching bit (Pr 6.40). When a value of 4 is selected the destination parameters for these digital I/O and Pr 6.40 can be modified by the user. (Note any
changes made to the destination parameters only become active after a drive reset).
If Pr 6.04 has been set to a value of 0 to 3, then setting Pr 6.04 to 4 does not automatically reconfigure terminals T25, T26 and T27 to their default
functions. To return terminals T25, T26 and T27 to their default functions, one of the following operations should be performed.
• Drive defaults should be restored. See section 5.8 Restoring parameter defaults in the Unidrive SP User Guide for details.
• Manually set Pr 6.04 to 4, Pr 6.40 to 0, Pr 8.22 to 10.33, Pr 8.23 to 6.30, and Pr 8.24 to 6.32.
* With software version V01.10.00 and later, Pr 6.29 can be used as a fast disable parameter. See Pr 6.29 on page 142 for more information.
Pr 6.29 reflects the state of the secure disable input and so it is not necessary to control this with a digital input, but the set up here is provided for
older products. Routing a digital input can be used for fast disabling, see Pr 6.29 for more details.

When the drive is enabled with this parameter at zero, the output frequency starts at zero and ramps to the required reference. When the drive is
enabled with this parameter at a non-zero value, the drive performs a start-up test to determine the motor speed and then sets the initial output
frequency to the synchronous frequency of the motor. The test is not carried out, and the motor frequency starts at zero, if the run command is given
when the drive is in the stop state, or when the drive is first enabled after power-up with Ur_I voltage mode, or when the run command is given with
Ur_S voltage mode. With default parameters the length of the test is approximately 200ms, however, if the motor has a short rotor time constant
(usually small motors) the time may be shorter. The drive will set the test time automatically if the motor parameters, including the rated load rpm, are
set up correctly for the motor.
For the test to operate correctly it is important that the stator resistance (Pr 5.17, Pr 21.12) is set up correctly. This applies even if fixed boost (Fd) or
square law (SrE) voltage mode is being used. The test uses the rated magnetizing current of the motor during the test, therefore the rated current
(Pr 5.07, Pr 21.07 and Pr 5.10, Pr 21.10) and power factor should be set to values close to those of the motor, although these parameters are not as
critical as the stator resistance. For larger motors it may be necessary to increase Pr 5.40 (spin start boost) from its default value of 1.0 for the drive
to successfully detect the motor speed.
It should be noted that a stationary lightly loaded motor with low inertia may move slightly during the test. The direction of the movement is undefined.
Restrictions may be placed on the direction of this movement and on the frequencies detected by the drive as follows:
When the drive is enabled with this bit at zero, the post ramp reference (Pr 2.01) starts at zero and ramps to the required reference. When the drive is
enabled with this parameter at one, the post ramp reference is set to the motor speed. When closed-loop vector mode is used without position
feedback (RFC mode), and catch a spinning motor is not required, this parameter should be set to zero as this avoids unwanted movement of the
motor shaft when zero speed is required. When closed-loop vector mode without position feedback (RFC mode) is used with larger motors it may be
necessary to increase Pr 5.40 (spin start boost) from its default value of 1.0 for the drive to successfully detect the motor speed.
This parameter permanently enables the Stop key on the drive such that the drive will always stop when the Stop key is pressed. If keypad mode is
selected this has no effect because the Stop key is automatically enabled.
The sequencer logic has been designed so that pressing the Stop key, whether the Stop key is enabled or not, does not make the drive change from
a stopped to a running condition. As the Stop key is also used to reset trips this means that if the Stop key is pressed when the drive is tripped, the trip
will be reset, but the drive does not start. (This does not apply to the UU trip which cannot be reset by the user, but is automatically reset when the d.c.
link voltage is high enough). Preventing the drive from starting when the stop key is pressed is implemented as follows.
Sequencer latching not enabled (Pr 6.40=0)
If the Stop key is pressed when the Stop key is enabled (Pr 6.12=1) or when the drive is tripped the sequencer run is removed, and so the drive stops
or remains stopped respectively. The sequencer run can only then be reapplied after at least one of the following conditions occurs.
1. Run forward, Run reverse and Run sequencing bits all zero
2. OR the drive is disabled via Pr 6.15 or Pr 6.29
3. OR Run forward and Run reverse are both active and have been for 60ms.
4. The drive is in the UU state.
The drive can then be restarted by activating the necessary bits to give a normal start.

Sequencer latching enabled (Pr 6.40=1)
If the Stop key is pressed when the stop key is enabled (Pr 6.12=1) or when the drive is tripped the sequencer run is removed, and so the drive stops
or remains stopped respectively. The sequencer run can only then be reapplied after at least one of the following conditions occurs.
1. Run forward, Run reverse and Run sequencing bits all zero after the latches
2. OR Not stop sequencing bit is zero
3. OR the drive is disabled via Pr 6.15 or Pr 6.29
4. OR Run forward and Run reverse are both active and have been for 60ms.
5. The drive is in the UU state.
The drive can then be restarted by activating the necessary bits to give a normal start. Note that Run forward and Run reverse together will reset the
stop key condition, but the latches associated with Run forward and Run reverse must then be reset before the drive can be restarted. It should be
noted holding the Run key and pressing the Stop key to reset the drive without stopping does not apply unless keypad reference mode is selected.
This parameter enables the Fwd/Rev key on the drive in keypad mode.
Setting this parameter to 0 will disable the drive. It must be at 1 for the drive to run.
When this parameter is set up correctly for the local currency, Pr 6.26 will give an instantaneous read out of running cost.
If this parameter is one the energy meter (Pr 6.24 and Pr 6.25) is reset and held at zero.

To enable the feature that indicates to the user when a filter change is due Pr 6.18 should be set to the time between filter changes. When the drive is
running, Pr 6.27 is reduced each time the runtime timer hour increments (Pr 6.23) until Pr 6.27 reaches 0, at which point Pr 6.19 is set to 1 to inform
the user that a filter change is required. When the user has changed the filter, resetting Pr 6.19 to 0 will indicate to the drive that the change has been
done and Pr 6.27 will be reloaded with the value of Pr 6.18. Pr 6.27 can be updated with the value of Pr 6.18 at any time by setting and clearing this
parameter manually. If Pr 6.18 = 0, then Pr 6.27 is held at zero and so parameters should be saved after Pr 6.18 has been setup so that this system
will function correctly after the drive is powered down and powered up again.
The powered-up clock always starts at zero each time the drive is powered-up. The time can be changed by the user from the keypad, serial comms
or an application module. If the data is not written with the various parts in the correct range (i.e. minutes are greater than 59, etc). the clock is set to
zero on the next minute. This clock may be used for time stamping the trip log if Pr 6.28 = 0.

The run time clock increments when the drive inverter is active to indicate the number of minutes that the drive has been running since leaving the
Control Techniques factory. This clock may be used for time stamping the trip log if Pr 6.28 = 1.
Pr 6.24 and Pr 6.25 form the energy meter that indicates the net energy supplied to/from the drive in kWh (i.e. energy supplied by the drive - energy
fed back to the drive). For motor control modes a positive value indicates net transfer of energy from the drive to the motor. For Regen mode a
positive value indicates a net transfer of energy from the supply to the drive. The energy meter is reset and held at zero when Pr 6.17 is one.
If the maximum or minimum of Pr 6.24 is reached, the parameter does not roll over, but is instead clamped at the maximum or minimum value.

The trip log includes time stamping for individual trips provided Pr 6.49 is set to one. If Pr 6.28 is zero, the powered-up clock is used for time
stamping. If Pr 6.28 is one, the run time clock is used for time stamping. It should be noted that changing this parameter clears the trip and trip time
logs.
This bit shows whether the drive is in the enable state or not.
Generally this will reflect the state of the enable input and shows the same value as Pr 8.09. However the disabled state can be forced by other
functions within the drive. Pr 8.09 will always follow the enable input state but the Pr 6.29 will be held at zero, indicating that the drive is forced into the
disable state by the following:
1. A digital input is routed to this parameter as described below to provide a fast disable and the input forces this parameter to zero.
2. Any of the following trips are active: OI.AC, PS.10V, PS.24V, OI.Br, OV.
Software V01.10.00 onwards
If the destination of one of the drive digital I/O (Pr 8.21 to Pr 8.26) is set to Pr 6.29 and the I/O is set as an input the state of the input does not affect
the value of this parameter as it is protected, however, it does provide a fast disable function. The secure disable input to the drive (T31) disables the
drive in hardware by removing the gate drive signals from the inverter IGBT's and also disables the drive via the software system. When the drive is
disabled by de-activating the secure disable input there can be a delay of up to 20ms. However, if a digital I/O is set up to provide the fast disable
function it is possible to disable the drive within 600us of de-activating the input. To do this the enable signal should be connected to both the secure
disable (T31) and to the digital I/O selected for the fast disable function. The state of the digital I/O including the effect of its associated invert
parameter is ANDed with the secure disable to enable the drive.
If the safety function of the Secure Disable input is required then there must not be a direct connection between the Secure Disable input (T31) and
any other digital I/O on the drive. If the safety function of the Secure Disable input and the fast disable function is required then the drive should be
given two separate independent enable signals. A safety related enable from a safe source connected to the Secure Disable input on the drive. A
second enable connected to the digital I/O on the drive selected for the fast disable function. The circuit must be arranged so that a fault which causes
the fast input to be forced high cannot cause the Secure Disable input to be forced high, including the case where a component such as a blocking
diode has failed.

In normal operation the sequencer has been designed to operate with Run forward / Run reverse controls, or with a Run control and a forward
reverse selector. If Run forward / Run reverse control is required then bits Pr 6.30 and Pr 6.32 should be used to control the drive (digital inputs should
not be routed to bits Pr 6.33 and Pr 6.34). If Run control with a forward reverse selector is required then bits Pr 6.33 and Pr 6.34 should be used to
control the drive (digital inputs should not be routed to bits Pr 6.30 and Pr 6.32).
The Run forward and Run reverse, or Run sequencing bits can be made latching by setting bit Pr 6.40. The Not stop bit (Pr 6.39) should be one to
allow the sequencing bit to be latched. If the Not stop bit is zero all latches are cleared and held at zero. The jog or jog reverse sequencing bits can
also cause the drive to run provided the motor is stopped when these bits are activated and the normal run sequencing bits are not providing a run
signal.

Digital inputs connected to limit switches should be routed to these parameters if fast stopping is required at a limit. In Open-loop mode the drive will
respond in 4.5ms (500μs digital input filter delay + 4ms software delay) and stop the motor using the currently selected ramp rate. In Closed-loop
vector and Servo modes the drive will respond in 750μs (500μs digital input filter delay + 250μs software delay) and stop the motor with zero ramp
rate (i.e. in current limit). The limit switches are direction dependant so that the motor can rotate in a direction that allows the system to move away
from the limit switch. (In open-loop frequency slaving mode both limit switches are active).

The drive event flags indicate certain actions have occurred within the drive as described below.
Defaults loaded (Bit 0)
The drive sets bit 0 when defaults have been loaded and the associated parameter save has been completed. The drive does not reset this flag
except at power-up. This flag is intended to be used by SM-Applications Solutions Module programs to determine when the default loading process is
complete. For example an application may require defaults that are different from the standard drive defaults. These may be loaded and another
parameter save initiated by the SM-Applications module when this flag is set. The flag should then be cleared so that the next event can be detected.
Drive mode changed (Bit 1)
The drive sets bit 1 when the drive mode has changed and the associated parameter save has been completed. The drive does not reset this flag
except at power-up. This flag is intended to be used in a similar way as bit 0.
Pr 6.42 and Pr 6.43 provide a method of controlling the sequencer inputs and other functions directly from a single control word. If Pr 6.43 = 0 the
control word has no effect, if Pr 6.43 = 1 the control word is enabled. Each bit of the control word corresponds to a sequencing bit or function as

Bits 0-7 and bit 9: sequencing control
When the control word is enabled (Pr 6.43 = 1), and the Auto/manual bit (bit7) are both one, bits 0 to 6 and bit 9 of the control word become active.
The equivalent parameters are not modified by these bits, but become inactive when the equivalent bits in the control word are active. When the bits
are active they replace the functions of the equivalent parameters. For example, if Pr 6.43 = 1 and bit 7 of Pr 6.42 = 1 the drive enable is no longer
controlled by Pr 6.15, but by bit 0 of the control word. If either Pr 6.43 = 0, or bit 7 of Pr 6.42 = 0, the drive enable is controlled by Pr 6.15.
Bit 8: Analog/preset reference
When the control word is enabled (Pr 6.43) bit 8 of the control word becomes active. (Bit 7 of the control word has no effect on this function). The state
of bit 8 is written to Pr 1.42. With default drive settings this selects analog reference 1 (bit8 = 0) or preset reference 1 (bit8 = 1). If any other drive
parameters are routed to Pr 1.42 the value of Pr 1.42 is undefined.
Bit12: Trip drive
When the control word is enabled (Pr 6.43) bit 12 of the control word becomes active. (Bit 7 of the control word has no effect on this function). When
bit 12 is set to one a CL.bit trip is initiated. The trip cannot be cleared until the bit is set to zero
Bit 13: Reset drive
When the control word is enabled (Pr 6.43) bit 13 of the control word becomes active. (Bit 7 of the control word has no effect on this function). When
bit 13 is changed from 0 to 1 the drive is reset. This bit does not modify the equivalent parameter (Pr 10.33).
Bit 14: Keypad watchdog
When the control word is enabled (Pr 6.43) bit 14 of the control word becomes active. (Bit 7 of the control word has no effect on this function). A
watchdog is provided for an external keypad or other device where a break in the communication link must be detected. The watchdog system can be
enabled and/or serviced if bit 14 of the control word is changed from zero to one with the control word enabled. Once the watchdog is enabled it must
be serviced at least once every second or an "SCL" trip occurs. The watchdog is disabled when an "SCL" trip occurs, and so it must be re-enabled
when the trip is reset. It should be noted that when data is transferred from a SMART card to the drive there may be a delay of up to 1.5s for the
comms to respond. Once the comms starts to respond again normally the watchdog will not time out for a further 2s even if it is not serviced. This
period is allowed for the system connected to the comms port to recover if required and to begin servicing the watchdog again.
The drive can operate from either a high voltage supply or a low voltage supply, usually from a battery. Different methods are used to connect the low
voltage battery supply depending on the frame size of the drive. This parameter, which indicates which supply is active, is set up to the correct value
just as the UU trip is reset. A low voltage battery supply should not be used without first consulting the appropriate documentation on the power and
control connections required for this mode.
0: Normal high voltage supply
The drive is operating in normal high voltage supply mode.
SP1xxx, SP2xxx, SP3xxx:
The drive is using the main power terminals to derive its control supplies. The drive will operate normally. Parameters that are saved at power-down
are saved when the supply is removed and a UU trip occurs.
SP4xxx, SP5xxx, SP6xxx, SPMxxx:
The drive is using the main power terminals to derive its control supplies and the battery mode enable power supply input has no supply connected.
The drive will operate normally. Parameters that are saved at power-down are saved when the supply is removed and a UU trip occurs.
1: Low voltage battery supply
The drive is operating in low voltage battery supply mode.
SP1xxx, SP2xxx, SP3xxx:
The drive is using the low voltage auxiliary power input to derive the power circuit supplies (i.e. gate drives, fans, etc). The main power terminals can
be connected to a different supply of any voltage up to the maximum normal supply level. All parameters voltage based parameters are calculated
from the auxiliary supply level and not the supply from the main power terminals. If the auxiliary supply and the main supply are different then these
parameters will not be correct. Parameters that are saved at power-down are not saved when the power is removed in this mode.
SP4xxx and larger:
The drive is using the battery mode enable input to derive the power circuit supplies (i.e. gate drives, fans, etc). A low voltage DC supply is connected
to the DC power terminals. All parameters that are calculated based on voltage are derived from the voltage connected to the power terminals.

For all sizes of drive in low voltage battery mode, 24V must also be supplied via the 24V control board power supply input. The drive will operate
normally except that mains loss detection is disabled, the braking IGBT will only operate when the drive is enabled, and the voltage levels contained
in the following table are used instead of the normal high voltage levels whatever the voltage rating of the drive.

Full scale voltage measurement and the over voltage trip level are defined by DC_VOLTAGE_MAX. However, the maximum level of the low voltage
battery supply voltage should not normally exceed 90% of this value to avoid spurious over voltage trips.
The drive thermal model system normally controls the fan speed, however the fan can be forced to operate at full speed if this parameter is set to 1.
When this is set to 1 the fan remains at full speed until 10s after this parameter is set to zero.
Note when the drive is in the UU state, the fan always runs at minimum speed.
This parameter defines the nominal supply voltage when operating in low voltage mode. The parameter is used to define the braking IGBT switching
threshold and the over voltage trip level for low voltage battery mode (see Pr 6.44).
SP0xxx, SP1xxx, SP2xxx and SP3xxx
Drives in these sizes ranges have a diode rectifier input stage with no direct monitoring system. Mains loss and phase loss detection is derived from
the DC bus voltage. This parameter has no effect.
SP4xxx, SP5xxx and SP6xxx
Drives in these sizes ranges have an active rectifier input stage that is used to control DC bus charging. Mains loss and phase loss detection is
derived from the DC bus voltage. The only status information taken from the input rectifier stage is an over temperature indication which gives an
Oht4 trip if active. This parameter has no effect on this feature. When the control system is leaving the mains loss ride through condition (ACUU) it is
important that no load is applied to the input rectifier until it is fully active. This feature can be disabled by setting this parameter to one.
SPMxxxx
Drives in this size range can use an active rectifier input stage that is used to control DC bus charging. These drives can be operated as a single
power module or the power modules can be operated in parallel. Mains and phase loss detection is derived from the DC bus voltage, but additional
monitoring is provided by the input rectifier controller as follows:
1. An over temperature indication from a single module or any module operating in parallel causes an Oht4.P trip if it is present for more than 0.5s.
This feature is not affected by this parameter.
2. A phase loss indication from a single module or any module operating in parallel causes a PH.P trip if it is present for more than 0.5s. If this
parameter is set to one, the drive is operating in regen mode or the drive is operating from a low voltage supply this feature is disabled.
3. A mains loss indication from any, but not all modules operating in parallel causes a PH.P trip if this condition is present for more than 0.5s. If this
parameter is set to one, the drive is operating in regen mode or the drive is operating from a low voltage supply this feature is disabled.
When the control system is leaving the mains loss ride through condition (ACUU) it is important that no load is applied to the input rectifier until it is
fully active. This feature can be disabled by setting this parameter to one.

The active rectifier status signals are monitored in one of the following ways:
1. When SPMAxxx drives are connected in parallel the status of the individual rectifiers is monitored through the parallel module control interface
system.
2. When SPMDxxx drives are connected in parallel the status of the individual rectifiers is combined and is monitored when the combined status
signals are connected to power module one.
3. When an external rectifier is used, these monitoring features are provided via digital I/O terminals using the rectifier monitoring feature of the
variable selector blocks (see menu 12).
The mains loss detection level can be adjusted using this parameter. If the value is reduced below the default value the default value is used by the
drive. If the level is set too high so that mains loss detection becomes active under normal operating conditions the motor will coast to a stop.
When power modules are connected in parallel various trips can be initiated from the power modules themselves. To aid identification of the source of
the trip the module number of the source can be stored in the module number and trip time log (Pr 10.41 to Pr 10.51). If the drive is a single module
drive (Sp1xxx to SP6xxx) the module number that is stored is normally zero.
However, a SPMAxxxx or SPMDxxxx drive is installed with the interface circuits normally intended for parallel operation, so if a SPMAxxxx or
SPMDxxxx drive is used as a single module then a module number of 1 is stored. If Pr 6.49 is zero the module number is stored in the module
number and trip time log. If this parameter is one, either the powered-up clock or run time clock is stored in the module number and trip time log as
defined by Pr 6.28. It should be noted that changing this parameter clears the trip, and module number and trip time logs.
The drive comms system 128 bytes buffer used with ANSI or Modbus rtu protocols via the 485 connector can be controlled by a Solutions Module
under certain circumstances. This parameter shows which node has control of the buffer (0 (drv) = drive, 1 (Slot1) = Solutions Module in slot 1, etc. If
a Solutions Module has control of the buffer the drive will use an alternative buffer for 485 comms and the following restrictions will apply:
1. Comms messages via the 485 port are limited to a maximum of 32 bytes
2. The 6 pin keypad port will operate correctly with an LED keypad, but it will no longer operate with an LCD keypad
3. Modbus messages using the CMP protocol can only route messages to nodes within the drive. It will not be possible for these to be routed further,
i.e. via CT Net on an SM Applications module.

When a drive with an internal rectifier is used this parameter should be left at zero. For a drive with an active external rectifier (used to control DC Bus
charging) this parameter should be the destination of the output of a variable selector set up for external rectifier monitoring. This allows the
monitoring block to prevent the drive from leaving the main loss ride through mode until the rectifier is fully active and phased forwards. If this feature
is not used the mains loss ride through mode ends as soon as the DC Bus voltage is above the mains loss detection level. The rectifier may still be
phasing forwards and the application of load at this point may cause the DC Bus voltage to fall back below the mains loss detection level again.

5.9 Menu 7: Analog I/O
Hardware
The drive has three analog inputs (AI1 to AI3) and two analog outputs (AO1 and AO2). Each input has a similar parameter structure and each output
has a similar parameter structure. The nominal full scale level for inputs in voltage mode is 9.8V. This ensures that when the input is driven from a
voltage produced from the drive's own 10V supply, the input can reach full scale.
Update rate
The analog inputs are sampled every 4ms except where the destinations shown in the table below are chosen, the input is in voltage mode and other
conditions necessary for short cutting are met.
It should be noted that the analog inputs are always sampled every 4ms in Open-loop mode. However, the window filter applied to analog input 1 (see
Pr 7.26) can be set to a time that is shorter than 4ms. There is no advantage in doing this, as it simply reduces the resolution of the input data, which
is still only sampled and routed to its destination parameter every 4ms.
Analog outputs are updated every 4ms except when one of the following is the source and high speed update mode is selected. In high speed mode
the output operates in voltage mode, is updated every 250μs, special scaling is used as described in the table and the user scaling is ignored.

Pr 4.17 - magnetising current 10.0V = Kc / 0.45
Pr 5.03 - output power
(Closed-loop vector and servo modes only)
The output is the product of the active current and the voltage component in phase with the
active current (vsy x isy).
10V would be produced when:
Active current = Kc / 0.45
Peak phase voltage in phase with the active current = DC_VOLTAGE_MAX / 2

This input operates in voltage mode only where -9.8V and +9.8V at the input correspond with -100.0% and 100.0% respectively in this parameter.
These inputs can operate in different modes defined by Pr 7.11 and Pr 7.15.
In current modes (modes 0 to 5) the minimum and maximum current values given in mA correspond with 0.0% and 100.0% respectively in Pr 7.02
and Pr 7.03. Therefore in modes 2 and 4 the parameter is at 0.0% when the input current is less than 4mA, and in modes 3 and 5 the parameter is at
100.0% when the input current is less than 4mA.
In voltage mode (mode 6) -9.8V and +9.8V at the input correspond with -100.0% and 100.0% respectively in Pr 7.02 and Pr 7.03.
When analog input 3 is in thermistor mode (modes 7 to 9) the display indicates the resistance of the thermistor as a percentage of 10kΩ
For drive sizes SP1xxx to SP5xxx two temperatures are available from the power circuit, and these are displayed in Pr 7.04 and Pr 7.05. For drive
sizes SP0xxx, SP6xxx and SPMxxxx three temperatures are available from the power circuit, and these are displayed in Pr 7.04, Pr 7.05 and Pr 7.36.
If SPMxxxx drives consist of more that one parallel power module the temperatures displayed are the highest value from any of the parallel modules.
If the temperature displayed in Pr 7.04, Pr 7.05 or Pr 7.36 exceeds the trip threshold for the parameter, the drive does not have parallel power
modules and is not a single power module that uses the parallel power module hardware, an Oht2 trip is initiated. This trip can only be reset if the
parameter that has caused the trip falls below the trip reset level. If the temperature exceeds the alarm level a "hot" alarm is displayed. If the
temperature for any of these monitoring points is outside the range -20°C to 150°C it is assumed that the monitoring thermistor has failed and a
hardware fault trip is initiated (Pr 7.04 - HF27, Pr 7.05 and Pr 7.36 - HF28).

Table 5-4 Power stage temperature 1 (Pr 7.04) in °C
Additional monitoring is used with drives sizes SP6xxx and SPMxxxx to detect failure of the power stage cooling fan. If this fan fails the monitoring
point used to derive power stage temperature 1 that is nearest the fan will rise temperature above it s normal level, but not above the trip temperature
for power stage. This is detected and can initiate an Oht2 trip. The trip thresholds are show below.
Table 5-5 Power stack temperature 2 (Pr 7.05) in °C
Table 5-6 Power stack temperature 3 (Pr 7.36) in °C
The control board temperature is also monitored and displayed in Pr 7.06. If the temperature displayed exceeds 92°C an O.Ctl trip is initiated, and this
trip can only be reset if the temperature falls below 87°C . If the temperature exceeds 85°C a "hot" alarm is displayed. If the temperature is outside
the range from -20°C to 150°C it is assumed that the monitoring thermistor has failed and an HF29 hardware fault trip is initiated.
Drive cooling fan
The drive cooling fan is controlled by the temperature from monitoring points and other actions as follows:
1. If Pr 6.45 = 1 the fan is at full speed for at least 10s.
2. If a Solutions Module indicates that it is too hot the fan is at full speed for at least 10s.
3. For drive sizes SP1xxx to SP2xxx the fan is at full speed if the drive is enabled and the highest power circuit temperature (Pr 7.04 or Pr 7.05) or
the temperature calculated for the case of the IGBT package exceed the threshold for the drive. The fan is at its low speed if this temperature falls
5°C below the threshold or the drive is disabled and the temperature is below the alarm level for Pr 7.04 and Pr 7.05.
4. For drive sizes SP3xxx to SPMAxxxx or SPMDxxx the fan speed is controlled above its minimum level if the drive is enabled and the highest
power circuit temperature (Pr 7.04, Pr 7.05 or Pr 7.36) or the temperature calculated for the case of the IGBT package exceed the lower threshold
for the drive. The maximum fan speed is reached when the highest of these temperatures exceeds the upper threshold. The fan is at its minimum
speed if the drive is disabled and the temperature is below the alarm level for Pr 7.04, Pr 7.05 and Pr 7.36.
5. For drive size SP0xxx the fan is always on when the drive or the braking IGBT are enabled and remains on for 10s after the drive or braking IGBT
is disabled.

The following modes are available for the analog outputs.
In voltage mode the output range is -10V to 10V. If the scaling parameter is 1.000 then -10V and 10V are produced when the source parameter is at -
maximum and maximum respectively. Different scaling can be applied with Pr 7.23. If the result of the scaling produces an output of more than +/-
100% the output is clamped within the +/-10V range.
In current modes with a scaling parameter of 1.000 the minimum and maximum current are produced when the source parameter is at 0 and
maximum respectively. Therefore in 4 - 20mA mode the output is 4mA when the source parameter is zero. Different scaling can be applied with
Pr 7.23. If the result of the scaling produces an output of more than 100% the output is clamped at 20mA.
If high speed update mode is selected and the source for the output is one of the parameters designated for high speed analog output operation (see
start of this section) the output is updated at a higher rate with special scaling. If the parameter selected is not designated for this mode the output is
updated at the normal rate. If speed feedback or power is selected for high speed mode for both analog output 1 and analog output 2 the setting is
ignored for analog output 2. If the high speed mode is selected the output is always a voltage signal.

The following modes are available for the analog outputs.
In voltage mode the output range is -10V to 10V. If the scaling parameter is 1.000 then -10V and 10V are produced when the source parameter is at -
maximum and maximum respectively. Different scaling can be applied with Pr 7.23. If the result of the scaling produces an output of more than +/-
100% the output is clamped within the +/-10V range.
In current modes with a scaling parameter of 1.000 the minimum and maximum current are produced when the source parameter is at 0 and
maximum respectively. Therefore in 4 - 20mA mode the output is 4mA when the source parameter is zero. Different scaling can be applied with
Pr 7.23. If the result of the scaling produces an output of more than 100% the output is clamped at 20mA.
If high speed update mode is selected and the source for the output is one of the parameters designated for high speed analog output operation (see
start of this section) the output is updated at a higher rate with special scaling. If the parameter selected is not designated for this mode the output is
updated at the normal rate. If speed feedback or power is selected for high speed mode for both analog output 1 and analog output 2 the setting is
ignored for analog output 2. If the high speed mode is selected the output is always a voltage signal.

Setting this bit will cause the drive to re-calibrate the full scale level of analog input 1 provided the input voltage is below +1.5V or above +2.5V. This
parameter is cleared by the software automatically when the calibration is complete. If the input voltage is above +2.5V the input voltage itself is used
for calibration, and so after calibration this level will be full scale for the input. If the input voltage is below +1.5V the internal reference is used for
calibration, and so the full scale will be nominally 9.8V after calibration. The calibration level is automatically stored on power-down. It should be noted
that the Analog input 1 offset trim is included in the input voltage when the input voltage itself is used for calibration, but this trim is not included when
the internal reference is used for calibration.
Analog input 1 is filtered using a window filter to remove quantization noise and adjust the resolution of this input. The length of the window can be
adjusted with this parameter. The shortest possible window is 250μs. It should be noted that if this input is not used as a speed reference (Pr 1.36,
Pr 1.37) or as a hard speed reference (Pr 3.22) the sample time affects the resolution. The nominal resolution is given by Pr 7.26 x 500 x 10, therefore
the default setting gives approximately 11 bit resolution.
If an analog input is used with 4-20mA or 20-4mA current loop modes the respective bit (Pr 7.28 - analog input 2 and Pr 7.29 -analog input 3) is set to
one if the current falls below 3mA. If the current is above 3mA with these modes or another mode is selected the respective bit is set to zero.

An offset can be added to each analog input with a range from -100% to 100%. If the sum of the input and the offset exceeds ±100% the results is
limited to ±100%.
This offers a simple control of Pr 7.19 to change the source for the analog output for use from Menu 0. When this parameter is set to 0 or 1 the drive
constantly writes Pr 5.01 or Pr 4.02 to Pr 7.19 respectively.
The IGBT junction temperature displayed in this parameter is the sum of the power circuit 1 temperature (Pr 7.04) and a thermal model of the drive
power stage. The calculated IGBT junction temperature is used to modify the drive switching frequency to reduce losses if the devices become too
hot (see Pr 5.18 on page 124).
If the temperature exceeds 135°C, the switching frequency is reduced provided that this feature has not been reached. The switching frequency can
be reduced from 12kHz to 6kHz to 3kHz, or from 16kHz to 8kHz to 4kHz. If at any time the calculated IGBT junction temperature exceeds 145°C, the
drive initiates an Ohtl.trip. Once the switching frequency has been reduced, the drive will attempt to restore the switching frequency every 20ms
provided the higher switching frequency does not raise the IGBT temperature above 135°C.
In addition to monitoring the IGBT junction temperatures the drive includes a thermal protection system to protect the other components within the
drive. This includes the effects of drive output current and DC bus ripple. The estimated temperature is displayed as a percentage of the trip level in
this parameter. If the parameter value reaches 100% an Oht3 trip is initiated.

5.10 Menu 8: Digital I/O
The drive has eight digital I/O terminals (T22, T24 to T29 and the relay) and an enable input. Each input has the same parameter structure. The digital
inputs are sampled every 4ms, except when inputs are routed to the limit switches Pr 6.35 and Pr 6.36 when the sample time is reduced to 250μs.
The digital input hardware (excluding the secure disable input) introduces a further 100us delay. The secure disable input hardware gives a typical
delay of 8ms (maximum 20ms). The digital outputs are updated every 4ms. Any changes to the source/destination parameters only become effective
after drive reset is activated.

Unidrive SP has a dedicated hardware enable/secure disable input which always controls Pr 6.29. If the enable is inactive the IGBT firing signals are
turned off without software intervention. As default (Pr 8.10 = 0) the drive is in the inhibit mode when the enable is inactive. Setting this parameter to
one causes the enable to behave as an Et trip input. When the input becomes inactive an Et trip is initiated. This does not affect Pr 10.32 (Et trip
parameter), therefore an Et trip can be initiated in this mode either by making the enable inactive or setting Pr 10.32 to one.

This parameter changes the logic polarity for digital inputs and digital outputs, but not the enable input, the relay output or the 24V output.
When this parameter is zero digital outputs are in push-pull mode. When this parameter is one either the high-side drive (negative logic polarity) or the
low-side driver (positive logic polarity) is disabled. This allows outputs to be connected in a wire-ORed configuration.

Menu 9 contains 2 logic block functions (which can be used to produce any type of 2 input logic gate, with or without a delay), a motorized pot function
and a binary sum block. One menu 9 or one menu 12 function is executed every 4ms. Therefore the sample time of these functions is 4ms x number
of menu 9 and 12 functions active. The logic functions are active if one or both the sources are routed to a valid parameter. The other functions are
active if the output destination is routed to a valid unprotected parameter.

If the delay parameter is positive, the delay ensures that the output does not become active until an active condition has been present at the input for
the delay time as shown below.
If the delay parameter is negative, the delay holds the output active for the delay period after the active condition has been removed as shown below.
Therefore an active input that lasts for 4ms or more will produce an output that lasts at least as long as the delay time.

The motorized pot modes are given in the following table.
When this bit is set to 0 the motorized pot output is limited to positive values only (i.e. 0 to 100.0%). Setting it to 1 allows negative outputs (i.e. ±100.0
%).
This parameter defines the time taken for the motorized pot function to ramp from 0 to 100.0%. Twice this time will be taken to adjust the output from
-100.0 % to +100.0 %.

This parameter can be used to restrict the output of the motorized pot to operate over a reduced range so that it can be used as a trim, for example.
These three bits control the motorized pot. The up and down inputs increase and decrease the output at the programmed rate respectively. If both up
and down are active together the up function dominates and the output increases. If the reset input is one, the motorized pot output is reset and held
at 0.0%.

5.12 Menu 10: Status and trips
Indicates the drive is not in the trip state. If Pr 10.36 is one and auto-reset is being used, this bit is not cleared until all auto-resets have been
attempted and the next trip occurs. The control board LED reflects the state of this parameter: LED on continuously = 1, LED flashing = 0.
Indicates that the drive inverter is active.
Open-loop
Indicates that the absolute value of the ramp output (|Pr 2.01|) is at or below the zero speed threshold defined by Pr 3.05.
Closed-loop and Servo
Indicates that the absolute value of speed feedback (|Pr 3.02|) is at or below the zero speed threshold defined by Pr 3.05.
In bipolar mode (Pr 1.10 = 1) this parameter is the same as zero speed (Pr 10.03). In unipolar mode this parameter is set if the absolute value of the
ramp output (Pr 2.01) or speed feedback (Pr 3.02) is at or below (minimum speed + 0.5Hz), or (minimum speed + 5rpm). Minimum speed is defined
by Pr 1.07. The parameter is only set if the drive is running.

This parameter is one if the post-ramp reference (Pr 2.01) is negative, or zero if the post-ramp reference is zero or positive.
This parameter is one if the speed feedback (Pr 3.02) is negative, or zero if the speed feedback is zero or positive.
Indicates that the drive has detected mains loss from the level of the DC bus voltage. This parameter can only become active if mains loss ride
through or mains loss stop modes are selected (see Pr 6.03 on page 135).
Regen
This parameter is the inverse of Pr 3.07.
This parameter indicates that the under voltage condition is active. Normally this condition exists when the UU trip is also active. However, when the
drive first powers up it remains in the under voltage state (i.e. this parameter is active) until the DC bus voltage exceeds the under voltage restart level
(see Pr 6.03 on page 135). As the UU trip voltage level is lower than the under voltage restart level this parameter is active, but a UU trip is not active
at power up until the DC bus voltage exceeds the under voltage restart level.
This parameter is set if the drive output current is larger than 105% of rated current (Pr 5.07) and the overload accumulator is greater than 75% to
warn that if the motor current is not reduced the drive will trip on an Ixt overload. (If the rated current (Pr 5.07) is set to a level above the maximum
heavy duty current (Pr 11.32) the overload alarm is given when the current is higher than 101% of rated current).
Indicates that any of the heat sink temperatures (Pr 7.04 or Pr 7.05) or the control board temperature (Pr 7.06) are above their alarm level.

Contains the last 10 drive trips. Pr 10.20 is the most recent trip and Pr 10.29 the oldest. When a new trip occurs all the parameters move down one,
the current trip is put in Pr 10.20 and the oldest trip is lost off the bottom of the log. Descriptions of the trips are given in the table below. A time stamp
can be stored for each trip (see Pr 10.41 to Pr 10.51). All trips are stored, including HF trips numbered from 17 to 32. (HF trips with numbers from 1 to
16 are not stored in the trip log). UU trips are not stored unless the drive is running when the trip occurs. Any trip can be initiated by the actions
described or by writing the relevant trip number to Pr 10.38. If any trips shown as user trips are initiated the trip string is "txxx", where xxx is the trip
number.
For drives SP4xxx and larger some trips are detected and initiated by the power module hardware (trips 101 -109). These are indicated by ".P" at the
end of the trip string. If the drive is a multi-module drive the number of the module that has caused the trip can be stored (see Pr 10.41 to Pr 10.51).

Trips can be grouped into the following categories. It should be noted that a trip can only occur when the drive is not tripped, or is already tripped but
with a trip with a lower priority number.
Unless otherwise stated trips cannot be reset until 1.0s after the trip has been accepted by the drive.
Power module trips
Trips 101 to 110 are power module trips that are initiated by the drive power electronics module, or modules for a multi-module parallel drive. The trip
identifier for each of these trips is in the form "xxxx.P". If the drive is a single module drive, and does not use the power interface intended for parallel
operation, (SP4xxx to SP6xxx only) OIdC.P, Oht4.P and Unid.P power module trip are possible. When the trip string is displayed the trip source
module number is not displayed and the module number stored in the "module number and trip time log" is zero. If the drive is a multi-module parallel
drive or a single module drive using the power interface intended for parallel operation (SPMAxxxx and SPMDxxxx) all the power module trips are
possible, the trip source module is displayed with the trip string and the module number is stored in the log. A PH.P trip is initiated if some, but not all
parallel modules detect mains loss via their input stage to ensure that the input stages of the remaining modules are not overloaded. If mains loss is
detected by all modules then the normal mains loss system based on DC bus monitoring is used. A PH.P trip occurs if any modules detect phase loss
via their input stage.The normal phase loss system which detects phase loss from DC bus voltage ripple cannot be used in case different phases
have been lost by different modules or if the system is a 12 pulse or higher system.
Braking IGBT control
The braking IGBT continues to operate even when the drive is not enabled (except if the active supply is a low voltage supply, see Pr 6.44), but is only
disabled if any of the following trips occurs or would occur if another trip had not already become active: OI.br, PS, It.br or OV or any HFxx trip.
UU trip
It should be noted that although the UU trip operates in a similar way to all other trips, all drive functions can still operate, but the drive cannot be
enabled. The following differences apply to the UU trip:
1. Power down save user parameters are saved when UU trip is activated except when the main high voltage supply is not active (Pr 6.44 = 1).
2. The UU trip is self-resetting when the DC bus voltage rises above the drive restart voltage level. If another trip is active instead of UU at this point,
the trip is not reset.
3. The drive can change between using the main high voltage supply and low voltage battery supply only when the drive is in the under voltage
condition (Pr 10.16 = 1). The UU trip can only be seen as active if another trip is not active in the under voltage condition..
4. When the drive is first powered up a UU trip is initiated if the supply voltage is below the restart voltage level and another trip is not active. This
does not cause save power down save parameters to be saved at this point.
Priority Category Trips Comments
1 Hardware faults HF01 to HF16
These indicate serious internal problems and cannot be reset. The
drive is inactive after one of these trips and the display shows
HFxx.
2 Non-resetable trips

For SP0xxx, SP1xxx and SP2xxx drives the default value is a suitable value for standard braking resistors that can be mounted within the drive
heatsink as given in the table below. For larger drives the default is 0.00.
This parameter defines the time period that the braking resistor installed can stand full braking volts without damage. The setting of this parameter is
used in determining the braking overload time.
This parameter defines the time between periods when the braking IGBT is on for the full power braking time so that the average power in the resistor
does not exceed the rating of the resistor.
For SP0xxx, SP1xxx and SP2xxx drives the default value is a suitable value for standard braking resistors that can be mounted within the drive as
given in the table below.

The braking resistor temperature is modelled by the drive as shown below. The temperature rises in proportion to the power flowing into the resistor
and falls in proportion to the difference between the resistor temperature and ambient. Under the conditions shown the resistor is heating up just to
100% of its rated temperature during each braking period.
Assuming that the full power braking time is much shorter than the full power braking period i.e. Pr 10.30 < Pr 10.31 /10 (which is normally the case)
the values for Pr 10.30 and Pr 10.31 can be calculated as follows:
Power flowing into the resistor when the braking IGBT is on, Pon = Full braking volts2
/ R
Where:
Full braking volts is defined in the table and R is the resistance of the braking resistor.
Full power braking time (Pr 10.30), Ton = E / Pon
Where:
E is the total energy that can be absorbed by the resistor when its initial temperature is ambient temperature.
Therefore full power braking time (Pr 10.30), Ton = E x R / Full braking volts2
If the average power rating of the resistor is not to be exceeded in the cycle shown in the diagram above, the average power in the resistor is given by
Pav = Pon x Ton / Tp
Where:
Tp is the full power braking period
Pon = E / Ton
Therefore Pav = E / Tp
Therefore full power braking period (Pr 10.31), Tp = E / Pav
The resistance of the braking resistor R, the total energy E and the average power Pav can normally be obtained for the resistor and used to calculate
Pr 10.30 and Pr 10.31.
If the profile of the power flowing from the motor is know then the instantaneous temperature can be calculated at any point by simulating the braking
resistor with the model shown below.
The temperature of the resistor is monitored by the braking energy accumulator (Pr 10.39). When this parameter reaches 100% the drive will trip if bit
1 of Pr 10.37 is 0, or will disable the braking IGBT until the accumulator falls below 95% if bit 1 Pr 10.37 is 1. The second option is intended for
applications with parallel connected d.c. buses where there are several braking resistors, each of which cannot withstand full d.c. bus voltage
continuously. The braking load will probably not be shared equally between the resistors because of voltage measurement tolerances within the
individual drives. However, once a resistor reaches its maximum temperature its load will be reduced, and be taken up by another resistor.

If this flag is set to one then the drive will trip (Et). If an external trip function is required, a digital input should be programmed to control this bit.
A zero to one change in this parameter will cause a drive reset. If a drive reset terminal is required on the drive the required terminal must be
programmed to control this bit.
If Pr 10.34 is set to zero then no auto reset attempts are made. Any other value will cause the drive to automatically reset following a trip for the
number of times programmed. Pr 10.35 defines the time between the trip and the auto reset (this time is always at least 10s for OI.AC, OI.br trips,
etc). The reset count is only incremented when the trip is the same as the previous trip, otherwise it is reset to 0. When the reset count reaches the
programmed value, any further trip of the same value will not cause an auto-reset. If there has been no trip for 5 minutes then the reset count is
cleared. Auto reset will not occur on a UU, Et, EEF or HFxx trips. When a manual reset occurs the auto reset counter is reset to zero.
If this parameter is 0 then Pr 10.01 (Drive ok) is cleared every time the drive trips regardless of any auto-reset that may occur. When this parameter is
set the 'Drive ok' indication is not cleared on a trip if an auto-reset is going to occur.

Each bit in this parameter has the following functions:
Stop on non-important trips
If bit 0 is set to zero then the drive simply trips when a non-important trip occurs. Non-important trips are: th, ths, Old1, cL2, cL3, SCL. If bit 0 is set to
one the drive will stop before tripping when one of these trips is initiated, except in Regen mode where the drive trips immediately.
Disable braking IGBT trips
For details of braking IGBT trip mode see Pr 10.31.
Disable phase loss trip (size 0 only)
The user can disable the phase loss trip in 200V size 0 drives as these are allowed to operate from a single phase supply. If bit 2 is set to zero the
phase loss trip is enabled. If bit 2 is set to one the phase loss trip is disabled in 200V size 0 drives only.
Disable braking resistor temperature monitoring failure detection
Size 0 drives have an internal user fit braking resistor with a thermistor to detect overheating of the resistor. As default bit 3 of Pr 10.37 is set to zero,
and so if the braking resistor and its thermistor is not installed the drive will produce a trip (br.th) because the thermistor appears to be open circuit.
This trip can be disabled so that the drive can run by setting bit 3 of Pr 10.37 to one. If the resistor is installed then no trip is produced unless the
thermistor fails, and so bit 3 of Pr 10.37 can be left at zero. This feature only applies to size 0 drives.
When a value other than zero is written to the user trip parameter the actions described in the following table are performed. The drive immediately
writes the value back to zero. If the value is not included in the table a trip is initiated with the same trip number as the value provided the drive is not
already tripped.

This parameter gives an indication of braking resistor temperature based on a simple thermal model, see Pr 10.30 and Pr 10.31 on page 198. Zero
indicates the resistor is close to ambient and 100% is the maximum temperature (trip level). A br.rS warning is given if this parameter is above 75%

Pr 6.49 = 0
These parameters are used to store the module number if the trip has been initiated by the power module hardware (trips numbers 101 to 110, HF30
and HF31). Pr 10.42 is used to store the module number related to the latest trip stored in Pr 10.20, and Pr 10.43 to Pr 10.51 store the module
numbers related to the trips stored in Pr 10.21 to Pr 10.29. If the drive has only one power module and this module is not using the power interface
intended for parallel operation (SP1xxx to SP6xxx) then Pr 10.42 to Pr 10.51 are always zero. If the drive has more than one parallel power module or
is a single module drive using the power interface intended for parallel operation (SPMAxxxx and SPMDxxxx) then the values in Pr 10.42 to Pr 10.51
can be used to identify the power module that initiated the trip. As these parameters are also used to show Hours.Minutes the module number is
shown with 2 decimal places, i.e. module 1 is shown as 0.01, etc.. Pr 10.41 is always zero.
Pr 6.49 = 1
When a trip occurs the reason for the trip is put into the top location in the trip log (Pr 10.20). At the same time either the time from the powered-up
clock (if Pr 6.28 = 0) or from the run time clock (if Pr 6.28 = 1) is put into Trip 0 time (Pr 10.41 and Pr 10.42). The times for earlier trips (Trip 1 to 9) are
moved to the next parameter in the same way that trips move down the trip log. The time for Trips 1 to 9 are stored as the time difference between
when Trip 0 occurred and the relevant trip in hours and minutes. The maximum time difference that can be stored is 600 hours. If this time is
exceeded the value stored is 600.00.
If the powered-up clock is used as the source for this function all the times in the log are reset to zero at power-up because they were related to the
time since the drive was powered-up last time. If the runtime clock is used the times are saved at power-down and then retained when the drive
powers up again. If Pr 6.28, which defines the clock source, is changed by the user the whole trip and trip time logs are cleared. It should be noted
that the powered-up time can be modified by the user at any time. If this is done the values in the trip time log remain unchanged until a trip occurs.
The new values put in the log for earlier trips (Trip 1 to 9) will become the time difference between the value of the power-up clock when the trip
occurred and the value of the powered-up clock when the latest trip occurred. It is possible that this time difference may be negative, in which case
the value will be zero.

This parameter may be used to scale the value of Pr 0.30 seen via the LED keypad (not via serial comms). Any parameter routed to Pr 0.30 may be
scaled. Scaling is only applied in the status and view modes. If the parameter is edited via the keypad it reverts to its un-scaled value during editing.
This parameter defines which menu 0 parameter is displayed on power-up.
Used to define the unique address for the drive for the serial interface. The drive is always a slave.
ANSI
When the ANSI protocol is used the first digit is the group and the second digit is the address within a group. The maximum permitted group number
is 9 and the maximum permitted address within a group is 9. Therefore, Pr 11.23 is limited to 99 in this mode. The value 00 is used to globally address
all slaves on the system, and x0 is used to address all slaves of group x, therefore these addresses should not be set in this parameter.
Modbus RTU
When the Modbus RTU protocol is used addresses between 0 and 247 are permitted. Address 0 is used to globally address all slaves, and so this
address should not be set in this parameter.
This parameter defines the communications protocol used by the 485 comms port on the drive. This parameter can be changed via the drive keypad,
via a Solutions Module or via the comms interface itself. If it is changed via the comms interface, the response to the command uses the original
protocol. The master should wait at least 20ms before sending a new message using the new protocol. (Note: ANSI uses 7 data bits, 1 stop bit and
even parity; Modbus RTU uses 8 data bits, 2 stops bits and no parity).

There will always be a finite delay between the end of a message from the host (master) and the time at which the host is ready to receive the
response from the drive (slave). The drive does not respond until at least 1ms after the message has been received from the host allowing 1ms for the
host to change from transmit to receive mode. This initial delay can be extended using Pr 11.26 if required for both ANSI and Modbus RTU protocols.
Note that the drive holds its own transmitters active for up to 1ms after it has transmitted data before switching to the receive mode, the host should
not send any data during this time.
Modbus RTU uses a silent period detection system to detect the end of a message. This silent period is either the length of time for 3.5 characters at
the present baud rate or the length of time set in Pr 11.26, whichever is the longest.
If this parameter is zero the drive is a standard Unidrive SP product. If this parameter is non-zero then the product is a derivative product. Derivatives
can have different defaults from the standard product and restrictions on the values allowed for some parameters.
The drive software version consists of three numbers xx.yy.zz. Pr 11.29 displays xx.yy and zz is displayed in Pr 11.34. Where xx specifies a change
that affects hardware compatibility, yy specifies a change that affects product documentation, and zz specifies a change that does not affect the
product documentation.

If any number other than 0 is programmed into this parameter user security is applied so that no parameters except Pr 11.44 can be adjusted with the
LED keypad. When this parameter is read via an LED keypad and security is locked it appears as zero. The security code can be modified via serial
comms etc. by setting this parameter to the required value, setting Pr 11.44 to 2 and initiating a reset by setting Pr 10.38 to 100. However security can
only be cleared via the LED keypad.
This parameter defines the drive mode. If this parameter is changed from the current drive mode, Pr x.00 is set to 1253, 1254, 1255 or 1256, and then
the drive is reset the drive mode is changed to the mode defined by this parameter. After the mode change the default settings of all parameters will
be set according to drive mode. The drive mode will not be changed if the drive is running. If the parameter value is changed and a reset is initiated,
but Pr x.00 is not equal to 1253, 1254, 1255 or 1256, or the drive is running, this parameter is set back to the value for the current drive mode and the
drive mode is not changed.
This parameter indicates the continuous current rating of the drive for Heavy Duty operation. See section 5.6 Menu 4: Torque and current control on

The drive software version consists of three numbers xx.yy.zz. Pr 11.29 displays xx.yy and zz is displayed in Pr 11.34. Where xx specifies a change
that affects hardware compatibility, yy specifies a change that affects product documentation, and zz specifies a change that does not affect the
product documentation.
This parameter can be used to initiate a ConF.P trip if the number of power modules actually connected together in a multi-module drive is different
from the expected number. This can be used for example to detect if the control connection between modules has been disconnected. If Pr 11.35 is
set to the default value of zero, this feature is disabled and ConF.P trips will not occur. If the feature is required, Pr 11.35 should be set to the actual
number of power modules and parameters should be saved. When the drive subsequently powers up the number of power modules is checked and if
the actual number of modules is different from Pr 11.35 a ConF.P trip is initiated.
V01.09.01 and earlier
This parameter indicates the number of modules installed in a system. If the drive cannot be used in a multi-module system the value is always 1.
This parameter shows the number of the data block last parameter or difference from default data block transferred from a SMARTCARD to the drive.
Data blocks are stored on a SMARTCARD with header information including a number to identify the block .The header information also includes the
type of data stored in the block (i.e. the file type), the drive mode if this is parameter or difference from default data, the version number and a
checksum. This data can be viewed through Pr 11.38 to Pr 11.40 by increasing or decreasing Pr 11.37. This parameter jumps between the data
numbers of the data blocks present on the card.

If this parameter is increased above the highest data block on the card it can have the special values given below:
1000 - shows the space left on the card for data blocks in 16 byte pages
1001 - shows the total space available on the card for data blocks in 16 byte pages
1002 - shows the state of the read-only (bit 0) and warning suppression flags (bit 1)
1003 - shows the product identifier
It should be noted that 16 bytes are reserved at the beginning and the end of the card that cannot be used to hold data. Therefore a 4096 byte card
has 4064 bytes (254 x 16 byte pages) available to hold data. Compatible cards from 4Kbytes to 512Kbytes may be used with the drive. The first 16
bytes on the card hold the card header information including the read-only flag, which can be set to make the whole card read-only, and the warning
suppression flag, which can be set to prevent C.rtg and C.Optn trips when data is transferred to the drive from a card. The card header also contains
the product identifier which is described later.
The actions of erasing a card, erasing a file, creating a new file, changing a menu 0 parameter, or inserting a new card will set Pr 11.37 to 0.
Various SMART card actions can be initiated via Pr x.00 or the copying (Pr 11.42) and reseting the drive as given in the table below:
The data, and the format of the data, is different depending on the method used to store it on a SMART card. The different formats are described
below. In addition to data transfers a compare function is provided.
If 8yyy is entered in Pr x.00 and the drive is reset data block yyy on the SMARTCARD is compared with the data in the drive. If the compare is
successful Pr x.00 is simply set to 0. If the compare fails a trip is initiated and parameter x.00 is not cleared. This function can be used with all data
block types except the option type (18).
Parameter file type data block
This type of data block is created when 3xxx in Pr x.00, the copying parameter (Pr 11.42) or auto/boot mode is used to initiate the transfer. The data
block (referred to as a parameter file) contains the complete data from all user save (US) parameters except those with the NC coding bit set.
Parameter RAM is used as the source of this information. Power-down save (PS) are not saved to the SMART card. When the data is transferred
back to a drive, it is transferred to the drive RAM and then the drive EEPROM. A parameter save is not required to retain the data after power-down.
Before the data is taken from the card, defaults are loaded in the destination drive using the same default code as was last used in the source drive.
Difference from defaults type data block
This type of data block is created when 4xxx in Pr x.00 is used to initiate the transfer. This data block format (referred to a difference from defaults file)
is different depending on the software version. The data held in the data block has changed between different software versions as follows:
Before V01.07.00
Parameters that are different from the last defaults loaded. The parameter must have the following attributes: NC=0 (clonable), ND=0 (has a default)
and US=1 (user save).
V01.07.xx
Parameters that are different from the last defaults loaded. The parameter must have the following attributes: NC=0 (clonable), ND=0 (has a default)
and US=1 (user save). In addition to these parameters all menu 20 parameters except Pr 20.00 if they are different from their default value.
V01.08.00 onwards
Parameters with the following attributes: NC=0 (clonable) and US=1 (user save), and menu 20 parameters except Pr 20.00 if they are different from
their default value. If a parameter is user save (US), but has no default (ND) it is saved on the card whatever its value.
It is possible to transfer parameters between drives with each of the software version dependant formats, however, the data block compare function
does not work with data produced by the different formats.
The data density is not as high as a parameter file type data block, but in most cases the number of differences from default is small and the data
blocks are therefore smaller. This method can be used, for example, for creating drive macros. Parameter RAM is used as the source of this
information.

When the data is transferred back to a drive, using 6yyy in Pr x.00, it is transferred to the drive RAM and then to the drive EEPROM. A parameter
save is not required to retain the data after power-down.
Onboard Application Lite user program data blocks
This type of data block is created when 5xxx in Pr x.00 is used to initiate the transfer. The Onboard Application Lite user program from a drive may be
transferred to/from internal flash memory from/to a SMART card. If the user program is transferred from a drive with no program loaded the block is
still created on the card, but contains no data. If this is then transferred to a drive the drive will then have no user program.
When transferring data between drives the following should be noted:
Parameter transfer failure
When parameter or default difference data is transferred to the drive the parameters are automatically saved to drive EEPROM. If the transfer from
the card fails for any reason the drive produces the appropriate trip. If the failure occurs after the transfer has begun, it is possible that some, but not
all the parameters will have been updated with the card data. However, if the transfer fails the parameters are not saved to drive EEPROM, therefore
only the RAM values will be incorrect. If the drive is powered down and then powered up again the original drive parameters will be restored.
Read-only function
Data blocks with numbers from 1 to 499 can be created or erased by the user. Data block with numbers 500 and above are read-only and cannot be
created or erased by the user. The whole card may also be protected from writing or erasing by setting the read-only flag. If the card or a data block
on the card is read-only, then the operation to erase the whole card is disabled.
Changing the drive mode
If the destination drive has a different drive mode to the parameters on the card, the drive mode will be changed by the action of transferring
parameters from the card to the drive. The only exception is that the mode cannot be changed to a mode that is not allowed for the particular
derivative of drive, e.g. Regen mode is not allowed with the Unidrive ES derivative. If an attempt is made to change to a disallowed mode the drive
produces a C.Typ trip.
Different voltage ratings
If the voltage rating of the source and destination drive are different then the parameters are transferred with the exception of rating dependent
parameters (RA attribute set, see table below), which are left at their default values. In this case a C.rtg trip is given as a warning that this has
happened. It is possible to suppress this warning trip for any data transfer to the drive, including a boot transfer at power-up by setting the warning
suppression flag for the whole card.
Different Solutions Modules installed
If the categories of the Solutions Modules installed to the source drive are different to the destination drive then the parameters are transferred with
the exception of the parameters in the menus of the modules that are different. These parameters are left at their default values. In this case a C.Optn
trip is given as a warning. It is possible to suppress this warning trip for any data transfer to the drive, including a boot transfer at power-up by setting
the warning suppression flag for the whole card.
Different current rating with a parameter file type data block
If the current ratings of the source and destination drive are different and the parameters stored as a parameter file (not differences from default) then
rating dependant parameters are set to their defaults and a C.rtg trip is produced as described above where the voltage ratings are different. It is
possible to suppress this warning trip for any data transfer to the drive, including a boot transfer at power-up by setting the warning suppression flag
for the whole card.
Different current rating with difference from defaults type data block
If the current ratings of the source and destination drives are different, but the parameters are stored as a difference from defaults file, the rating
dependant parameters are transferred from the card to the drive and the appropriate maximums are applied. The C.rtg is still produced unless it is
suppressed. To ensure that the performance of the destination drive is similar to that of the source drive, the speed controller gains and current
controller gains are scaled as shown in the table below. Note that the gain scaling is only applied when the data block number is less than 500.

Effects of variable maximums if ratings or options are different
It should be noted that if ratings of the source and destination drives are different, or the Solutions Modules installed to the source and destination
drives are different, it is possible that some parameters with variable maximums may be limited and not have the same values as on the card. For
example the user current maximum scaling (Pr 4.24) is rating dependent and could be set to its default value when it is transferred between drives of
different ratings, but this could also affect the torque reference (Pr 4.08) as this uses Pr 4.24 as its maximum. Also different position feedback
Solutions Modules can apply different limits on the speed references, therefore these can be affected when parameters are transferred between
drives with different position feedback Solutions Modules installed where the Solutions Module is being used for the drive position feedback.
Unexpected rating changes
Some drive ratings may change between software versions, for example the derating factor for multi-module drives has changed between versions
V01.08.01 and V01.09.00. These changes will cause a C.rtg trip when parameters are transferred between drives of different software versions
where the rating has changed.
Product identifier
When a SMART card is used with software version V01.11.00 onwards it must have the correct product identifier in the card header to give full
functionality with the drive. The product identifier is written to the card when the whole card is erased.
If the identifier does not match the drive product and the card contains any data blocks a C.Prod trip is produced. Also if the following functions are
initiated a C.Acc trip is produced and the card or drive data is not affected: erase file, transfer data block from card to drive, or transfer data block from
drive to card. It is still possible to use Pr 11.37 to browse information about the whole card (i.e. Pr 11.37 = 1000 to 1003), but it is not possible to see
the data block information (i.e. Pr 11.37 < 1000). It is also possible to change the card header information (i.e. read-only flag and warning suppression
flag). This feature allows the read-only flag to be cleared so that a card can be erased to be used with the product that performs the card erase.
If the card does not contain any data blocks (i.e. an erased card) and the identifier does not match that of the drive then the drive will automatically
change the identifier on the card to match when it is first inserted.

* Modes 1 and 2 are not US (i.e. not saved when drive parameters are saved), mode 3 and 4 are US.
Therefore this parameter can only be saved to EEPROM if it has a value of 0, 3 or 4.
Reading (1)
Setting Pr 11.42 to 1 and resetting the drive will transfer the data from the card into the drive parameters and then the drive EEPROM, provided data
block 1 exists and is a parameter file for the current drive mode. All smart card trips apply. When the action is complete this parameter is automatically
reset to zero.
Programming (2)
Setting Pr 11.42 to 2 and resetting the drive will save the parameters to a card, i.e. equivalent to writing 3001 to Pr x.00. If the data block already
exists it is automatically over-written. When the action is complete this parameter is automatically reset to zero.
Auto (3)
Changing Pr 11.42 to 3 and resetting the drive will save the complete parameter set from the drive parameters to the card, i.e. equivalent to writing
3001 to Pr x.00. If the data block already exists it is automatically overwritten. If the card is removed when Pr 11.42 is set to 3, Pr 11.42 will be set to
0. The action of setting Pr 11.42 to 0 when a card is removed forces the user to change Pr 11.42 back to 3 if auto mode is still required. The user will
need to set Pr 11.42 to 3 and reset the drive to write the complete parameter set to the new card.
When a parameter in menu zero is changed via the keypad and a card is installed the parameter is saved both to the drive EEPROM and the card.
Only the new value of the modified parameter is written to the EEPROM and the card. If Pr 11.42 was not cleared automatically when a card is
removed, then when a new card is inserted that contains data block 1 the modified parameter would be written to the existing data block 1 on the new
card and the rest of the parameters in this data block may not be the same as those in the drive.
When Pr 11.42 is equal to 3 and the parameters in the drive are saved, the card is also updated, therefore the card becomes a copy of the drive
parameters. At power up, if Pr 11.42 is set to 3, the drive will save the complete parameter set to the card. This is done to ensure that if a card is
inserted while the drive is powered down the new card will have the correct data after the drive is powered up again.
Boot (4)
When Pr 11.42 is set to 4 the drive operates in the same way as with Pr 11.42 set to 3 and automatically creates a copy of it parameters on a SMART
card. Pr 11.42 has the NC (not clonable) attribute, and so it does not have a value stored on a SMART card in the normal way. However, when data is
transferred to a card from the source drive the value of this parameter is held in the header of parameter or difference from default file type data
blocks so that the destination drive can detect when boot transfer is required on power-up (i.e. the source drive had this parameter set to 4). If a card
is present at power up, and it has Pr 11.42 stored as 4 in the header of a parameter file or difference from default file as data block 1 then the following
actions are taken.
1. The parameters from data block 1 are transferred to the drive and then saved in drive EEPROM.
2. If data block 2 exists and is type 17 the user program from this data block is transferred to the drive.
3. Parameter Pr 11.42 is set to zero after the data transfer is complete.
It is possible to create a difference from default bootable file by setting parameter Pr x.00 to 2001 and resetting the drive. This type of file causes the
drive to behave in the same way at power-up as a file created with boot mode set up with Pr 11.42. The difference from default file has the added
advantage of including menu 20 parameters. A bootable difference from default file can only be created in one operation and parameters cannot be
added as they are saved via menu zero.
When the drive is powered up it detects which Solutions Modules are installed before loading parameters from a SMART card which has been set up
for boot mode. If a new Solutions Module has been installed since the last time the drive was powered up, the drive produces a SLx.dF trip and then
proceeds to transfer the parameters from the SMART card. If the parameter data in the card includes the parameters for the newly installed Solutions
Module then these are also transferred to the drive. Once the transfer is complete the drive parameters are automatically saved to the drive
EEPROM. The SLx.dF trip can be reset either by resting the drive or powering down and then powering up again. Because the parameters are
transferred to the drive after detecting the Solutions Modules it is possible to fit the required Solutions Modules to a drive (corresponding to the
modules installed when the SMART card data was stored) and transfer the parameters to the drive including those for the Solutions Modules.

Setting this parameter to a non-zero value and resetting the drive loads defaults as follows. This parameter is automatically reset to zero when the
action is complete.

The keypad can adjust this parameter even when user security is set.
When this bit is set to one the motor 2 parameters in menu 21 become active instead of the equivalent parameters in other menus. Changes will only

reset to zero.

The threshold detector compares the modulus of the source input value (defined by Pr 12.03, Pr 12.23), converted to a percentage of its maximum
value, with the threshold level (Pr 12.04, Pr 12.24). If the value is greater or equal to the threshold plus half the hysteresis band (Pr 12.05, Pr 12.25)
the output becomes active, or if the value is less than the threshold minus half the hysteresis band the output becomes inactive. The output may be
inverted if required by setting the invert flag (Pr 12.06, Pr 12.26). The result is routed to the destination (defined by Pr 12.07, Pr 12.27).

The variable selectors allow two source values (defined by Pr 12.08, Pr 12.28 and Pr 12.09, Pr 12.29) to be combined as defined by the mode
(Pr 12.10, Pr 12.30) to produce an output (Pr 12.12, Pr 12.32) which can be routed to the destination parameter (defined by Pr 12.11, Pr 12.31). The
actions of the variable selector are defined by the mode parameter as given below. If the mode parameter is changed or the variable selector is
disabled because neither source is routed to a valid parameter all the internal state variables (i.e. time constant accumulator, etc). within the selector
are reset. When the Sectional control mode is selected the function is also reset, and the output is held at zero, when the control (Pr 12.15 or
Pr 12.35) is zero. It is active when the control has a non-zero value.

Sectional control
The sectional control function is intended to apply scaling and a speed offset to a 16 bit position value to generate a new 16 bit position value. The
output can be used as an input to the position controller (menu 13) or to generate an encoder simulation output via the SM-Universal encoder plus
module. This function can be selected for either variable selector, but the description below relates to variable selector 1.
The position input can be derived from any parameter, however it is intended to be used with a position value that has a range from 0 to 65535. The
input is scaled so that as Pr 12.13 is varied between -4.000 and 4.000, the proportion of the input position change added to the accumulator varies
from 0.000 to 2.000 (the change of position input value is added without scaling if Pr 12.13 is 0.000). The remainder from the scaling division is stored
and then added at the next sample to maintain an exact ratio between the position input and the position output, provided the speed input is zero. The
controller only takes the change of position from the input source parameter, and not the absolute value, so that when the controller is first made
active the output does not jump to the source position, but only moves with any changes of source position after that point in time.
The range of the output of the accumulator is 0.00% and 100.00%. Unlike other functions the value is not simply limited, but rolls under or over
respectively. Although the output destination can be any parameter it is intended to be used with a position value that has a range from 0 to 65535.
The speed input defines a speed offset with a resolution of 0.1rpm. Full scale of the source parameter corresponds to 1000.0rpm. Scaling may be
applied using Pr 12.14 to give a full scale value of 4000.0rpm. The speed input is added to the accumulator to move the output position forwards or
backwards with respect to the position input.
This sample time for this function is 4ms x number of menu 9 and 12 functions active. Extending the sample time does not cause any overflow errors
within the function, however, care must be taken to ensure that the input or output positions do not change by more than half a revolution within the
sample time, i.e for a sample time of 4ms the input or output speed should not exceed 7500rpm, for a sample time of 8ms the speed should not
exceed 3750rpm, etc. If the output of this function is to supply a reference to the position controller in menu 13 it must be the only user function in
menu 9 or 12 enabled. If another function is enabled the input to the position controller will only change every 8ms (i.e. every 2 samples of
the position controller) and the speed reference applied to the drive could be very noisy.
The diagram below shows how the variable selector in Sectional control mode can be used to provide a position reference for the drive and act as a
source for encoder simulation to give the position reference for the next drive in the system.

The input reference is provided by the previous drive in the system via the SM-Universal Encoder Plus module and is used as the position source
(Pr 12.08) for the variable selector. The destination of the variable selector is the local position reference for the menu 13 position controller
(Pr 13.21). Pr 13.21 counts up or down based on the delta position from the variable selector and rolls over or under at 65535 or 0. If the controller is
set up to ignore the local reference turns then Pr 13.21 can be used as the position controller reference. If Pr 13.21 is also used as the encoder
simulation source the local reference can also be used to give the reference for the next drive in the system. With this arrangement a ratio is provided
between the input reference and output reference within the variable selector. An addition ratio can be provided within the position controller between
the position in Pr 13.21 and the position reference used by the position controller. The variable selector speed reference can be used to move the
position reference forwards or backwards with respect to the input reference.
11. External Rectifier (SPMC/U) Monitor
This mode is intended to monitor an external rectifier system (SPMC/U) to provide over temperature monitoring, phase loss detection and mains loss
detection. The variable selector inputs should be routed to digital inputs on the drive or a Solutions Module, which are connected to the (SPMC/U)
rectifier status outputs. The external rectifier monitor produces a number of actions depending on the state of the inputs as given in the table below.
The OK/healthy state becomes active immediately both inputs are high, but the other states only become active when the required inputs have been
active for at least 0.5s. The high state is defined as a value greater than or equal to half the source maximum and the low state is defined as a value
less than half the source maximum (with the scaling parameters set to 1.000). If digital inputs are used as the sources and the scaling parameters are
1.000, high is therefore defined as 1, and low is defined as 0. The variable selector output gives 0% if the rectifier is OK/healthy, otherwise it gives
100%. The output should be routed to Pr 6.51 (rectifier not active) so that the drive is not allowed to leave the main loss condition if the rectifier is not
fully phased forwards.
For more information about Oht4.P and PH.P trips, refer to the Unidrive SPM User Guide.
5.14.1 Brake control function
The brake control function can be used to control an electro-mechanical brake via the drive digital I/O. A brake control function is provided for open-
loop operation of induction motors (Open-loop mode) and an alternative brake control function is provided for closed-loop operation of induction
motors or servo motors (Closed-loop vector and Servo modes). The parameters that are common to both brake control functions (Pr 12.40 and
Pr 12.41) are described below. The other parameters used by each of the brake control functions are then described in the section for the appropriate
function.
This parameter should be used as a source for a digital output to control an electro-mechanical brake. This parameter is one to release the brake and
zero to apply the brake. Digital I/O can be automatically configured to use this parameter as a source (see Pr 12.41).

The following tables show the automatic parameter changes that occur to set up digital I/O2 (T25) and the relay output (T41/42) after drive reset when
Pr 12.41 has been changed. The changes are done in two stages: the first stage restores the I/O used as defined by the initial setting of Pr 12.41 and
the second stage sets up the I/O as defined by the new setting of Pr 12.41.

The brake control functions are provided to allow well co-ordinated operation of an external brake with the drive. While both hardware and
software are designed to high standards of quality and robustness, they are not intended for use as safety functions, i.e. where a fault or
failure would result in a risk of injury. In any application where the incorrect operation of the brake release mechanism could result in injury,
independent protection devices of proven integrity must also be incorporated.

The control terminal relay can be selected as an output to release a brake. If a drive is set up in this manner and a drive replacement takes
place, prior to programming the drive on initial power up, the brake may be released.When drive terminals are programmed to non default
settings the result of incorrect or delayed programming must be considered. The use of a Smartcard in boot mode or an SM-Applications
module can ensure drive parameters are immediately programmed to avoid this situation.

The current magnitude is compared to an upper and lower threshold by a comparator with hysteresis to give torque present and drive output open
detection functions respectively. The upper and lower threshold currents are given as a percentage of motor current defined by Pr 5.07 (or Pr 21.07 if
motor map 2 is selected). The upper threshold should be set to the current level that indicates that there is magnetizing current and sufficient torque
producing current in the motor to deliver the required amount of torque when the brake is released. The output of the comparator remains active after
this level has been reached unless the current subsequently falls below the lower threshold which should be set to the required level to detect the
condition where the motor has been disconnected from the drive. If the lower threshold is set greater or equal to the upper threshold, the upper
threshold applies with a hysteresis band of zero. If Pr 12.42 and Pr 12.43 are both set to zero then the output of the comparator is always one.
The frequency comparator can be used to detect when the motor frequency has reached a level where the motor can produce the required amount of
torque to ensure that the motor rotates in the demanded direction when the brake is released. This parameter should be set to a level slightly above
the motor slip frequency that is likely to occur under the highest expected load that is applied to the motor when the brake is released.
The brake apply frequency threshold is used to ensure that the brake is applied before the motor frequency reaches zero and to prevent the motor
rotating (in the reverse direction due to an overhauling load for example) during the brake apply time. If the frequency falls below this threshold, but
the motor is not required to stop (i.e. reversing direction without stopping), provided the Reference on parameter (Pr 1.11) remains at one, the brake
is not applied. This prevents the brake from activating and de-activating as the motor passes through zero speed.

The pre-brake release delay is used to allow time for the motor torque to reach the required level before the brake is released. This time should allow
for the motor flux to reach a significant proportion of the rated level (2 or 3 times the rotor time constant of the motor), and the time for slip
compensation to become fully active (at least 0.5s). During the Pre-brake delay period the frequency reference is held constant (Pr 2.03 = 1).
The post-brake release delay is used to allow for the brake release time. During this period the frequency reference is held constant (Pr 2.03 = 1), so
that there is no sudden increase in motor speed when the brake actually releases.

If the current magnitude falls below the lower current threshold the brake is applied immediately. The lower threshold should be set to the required
level to detect the condition where the motor has been disconnected from the drive. If this parameter is set to zero the loss of current will not cause
the brake to be applied. However, the flux detection and current threshold latch will be reset when the drive is disabled.
When stopping, the drive reference can be removed (i.e. Pr 1.11 = 0), but the brake will remain energized (open) until the motor has remained at a
speed below the brake apply speed for the delay defined by Pr 12.46. The delay prevents rapid activation and de-activation of the brake when fine
control of a motor is required close to zero speed.
See Pr 12.45.
The post-brake release time is used to allow for the brake release time. From the time that the drive is enabled and then during this period the speed
reference is held constant at zero, so that there is no sudden increase in motor speed when the brake actually releases.
The brake apply delay is used to allow for the brake application time. During this period the Hold zero speed parameter (Pr 6.08) is one, and so the
drive is enabled with zero speed reference. This ensures that the motor remains stationary while the brake is being applied.

If this parameter is zero then ramp hold only is applied when the drive is not active and until the end of the post-brake release delay to ensure that the
speed reference remains at zero until the brake has released. If this parameter is set to one the position controller (see menu 13) is also enabled
(Pr 13.10 = 1) and the local position reference source is selected (Pr 13.04 = 4(LocAL)) during the period when ramp hold is active. Provided the
default, non-absolute mode, is selected the position controller can help to limit the movement of the motor when the brake is released. When Pr 12.49
is changed from one to zero Pr 13.04 and Pr 13.10 are automatically set to zero.

5.15 Menu 13: Position control
Menu 13 provides a position control system for the drive in open-loop mode and closed-loop modes (closed-loop vector and servo). The position
reference can be taken from the drive encoder, from a position feedback module or from a local reference defined in this menu. The reference
includes a relative jog function that can be used to advance or retard the position reference at a defined speed and a ratio that can scale the
reference. The feedback position can be taken from the drive encoder or from a position feedback module. As well as giving position control the
controller can provide shaft orientation within one revolution in conjunction with the drive sequencer (see section 5.8 Menu 6: Sequencer and clock on
page 134). The sample time for the position controller is 4ms and the output is supplied to the speed or frequency reference every 4ms.
Open–loop mode
The position controller outputs are a velocity feed forward and a speed reference (both in 0.1rpm units). When the position controller is selected (i.e.
Pr 13.10 is non-zero) these values are converted to 0.1Hz units and combined as shown below, before being written to the velocity feed forward
parameter (Pr 1.39). The velocity feed forward select (Pr 1.40) is always one when the position controller is selected. When the position controller is
de-selected (i.e. Pr 13.10 is changed to zero) Pr 1.39 and Pr 1.40 are set to zero. In open-loop mode the motor control must pass through the drive
ramp system, and so for stable operation short ramp times are normally required.
Closed-loop modes
The position controller outputs are a velocity feed forward and a speed reference (both in 0.1rpm units). When the position controller is selected (i.e.
Pr 13.10 is non-zero) these values are written directly to the velocity feed forward (Pr 1.39) and hard speed reference (Pr 3.22) respectively. Also the
hard speed reference select (Pr 3.23) is forced to a one and the velocity feed forward select (Pr 1.40) is set to one when a controller mode giving
velocity feed forward is selected. When the position controller is de-selected (i.e. Pr 13.10 is changed to zero) Pr 1.39, Pr 1.40, Pr 3.22 and Pr 3.23
are set to zero.

For normal position control the position changes from the reference and the feedback are accumulated in an integrator during each sample. The
integrator is large enough to guarantee that the position controller will operate with a position error within the range -32,768 revolutions to +32,767
revolutions before rolling over. The position error is displayed in Pr 13.01, Pr 13.02 and Pr 13.03. Pr 13.01 shows the turns error, Pr 13.02 shows the
error within a revolution in 1/216
counts per revolution units and Pr 13.03 shows the fine position error in 1/232
counts per revolution units. These
values are both positive and negative and so they can be used to show the following error with different levels of resolution.
For orientation mode the error between the orientation position and the position feedback source is shown in Pr 13.02.
The reference and feedback positions can be taken from the drive encoder or a position feedback Solutions Module in one of the Solutions Module
slots. The reference can also be taken from the local reference parameters. If the reference and feedback sources are the same the position
controller cannot be enabled. If a Solutions Module slot is selected as a source, but the module is not a position feedback category Solutions Module
the position controller cannot be enabled. Orientation mode can always be enabled in closed-loop modes.

An exact ratio can be applied to the position reference with these two parameters. The ratio cannot be changed when the drive is enabled without
causing abrupt changes of position. Although it is possible to set up ratios with a high gain or even with a denominator of zero, the drive limits the
resultant gain of the ratio block to 4.000.
The gain of the position controller is controlled with this parameter. The standard units within the drive for position are in 232 counts per revolution and
the standard units for speed are 0.1rpm, however the position controller gain is given in rads-1
/rad. These units are consistent with units such as
mms-1/mm or ms-1/m often used for linear control applications. An error of 1 radian (10430 counts in the position error (Pr 13.02)) gives a speed
reference of 1rads-1
(9.5rpm) when this gain is 1.00.
This parameter is used to set the position controller mode as shown in the following table.

Rigid position control
In rigid position control the position error is always accumulated. This means that, if for example, the slave shaft is slowed down due to excessive
load, the target position will eventually be recovered by running at a higher speed when the load is removed.
Non-rigid position control
In non-rigid position control the position loop is only active when the 'At Speed' condition is met (see Pr 3.06 on page 53). This allows slippage to
occur while the speed error is high. It may be necessary to increase the ‘At Speed’ window in Pr 3.06 and Pr 3.07 with some lower resolution
feedback devices.
Velocity feed forward
The position controller can generate a velocity feed forward value from the speed of the reference encoder. The feed-forward value is passed to menu
1, and so ramps may be included if required. Because the position controller only has a proportional gain, it is necessary to use velocity feed-forward
to prevent a constant position error that would be proportional to the speed of the reference position.
If for any reason the user wishes to provide the velocity feed forward from a source other than the reference position, the feed forward system can be
made inactive, i.e. Pr 13.10 = 2 or 4. The external feed forward can be provided via Menu 1 from any of the frequency/speed references. However, if
the feed forward level is not correct a constant position error will exist.
Relative jogging
If relative jogging is enabled the feedback position can be made to move relative to the reference position at the speed defined by Pr 13.17.
Orientation
If Pr 13.10 is 5 the drive orientates the motor following a stop command. If hold zero speed is enabled (Pr 6.08 = 1) the drive remains in position
control when orientation is complete and holds the orientation position. If hold zero speed is not enabled the drive is disabled when orientation is
complete.
If Pr 13.10 is 6 the drive orientates the motor following a stop command and whenever the drive is enabled provided that hold zero speed is enabled
(Pr 6.08 = 1). This ensures that the spindle is always held in the same position following the drive being enabled.

When orientating from a stop command the drive goes through the following sequence:
1. The motor is decelerated or accelerated to the speed limit programmed in Pr 13.12, using ramps if these are enabled, in the direction the motor
was previously running.
2. When the ramp output reaches the speed set in Pr 13.12, ramps are disabled and the motor continues to rotate until the position is found to be
close to the target position (i.e. within 1/32 of a revolution). At this point the speed demand is set to 0 and the position loop is closed.
3. When the position is within the window defined by Pr 13.14, the orientation complete indication is given in Pr 13.15.
The stop mode selected by Pr 6.01 has no effect if orientation is enabled.
Orientation is only possible with a suitable feedback device such as an absolute encoder (sincos encoder with communications or communications
only encoder), incremental encoder with a marker pulse or a 2 pole resolver.
When this parameter is set to one and the position controller mode (Pr 13.10) is 1 or 2, the position error integrator is loaded with the absolute
position error defined by the position sources when the position controller is disabled. (The position controller is disabled under the following
conditions: when the drive is in the inhibit, ready or tripped states; either the reference or feedback position sources from Solutions Modules are
invalid; the position feedback is not correctly initialized (Pr 3.48 = 0); the position control mode (Pr 13.10) is changed; this parameter (Pr 13.11) is
changed; or the position error reset (Pr 13.16) is set to one). Therefore when this parameter is one the position controller operates on the absolute
position from the reference and feedback. If the feedback device is not absolute then the absolute position is the change of position since the drive
was powered-up.
When this parameter is zero or the position control mode is not 1 or 2 the error integrator is loaded with zero when the position controller is disabled
therefore the position controller operates on the relative position changes of the reference and feedback from the point when the position controller is
re-enabled.
It should be noted that the value of this parameter does not affect the operation of the marker reset for any position source. If the marker position reset
disable (Pr 3.31 for the drive encoder, or similar for Solutions Modules) is zero, the position controller takes the position source including the effect of
the marker. When a marker event occurs the position and fine position are reset to zero, but the turns are not affected. If the marker position reset
disable is one then the marker events have no effect on the position source used by the position controller.
This parameter limits the velocity correction applied by the position controller. In closed-loop modes this value is also used as the reference during
orientation.

Pr 13.13 defines the position as a 1/216

reference for orientation in 1/216

is used. This allows all three parts of the local reference position to be changed without data skew problems.
The local reference consists of a turns, a position and a fine position value. When Pr 13.24 is zero the reference is a 48bit position made from these
three values.
If Pr 13.24 is set to one the local reference is a 32bit position made from the position and fine position values. The position delta, used as the input to
the position controller, is calculated correctly even when the turns are ignored as the 32bit position is treated as a roll-over/roll-under counter. This
feature can be used, for example, with the local reference when only the position (and not the turns or fine position) is available. This feature is not
available when absolute mode is selected (Pr 13.11 = 1).

Subject to the limits the PID controller output is given by
output = error x [P + I/s + Ds/(0.064s + 1)]
Where:
error = reference - feedback
P = proportional gain = Pr 14.10
I = integral gain = Pr 14.11
D = differential gain = Pr 14.12
Therefore with an error of 100% and P = 1.000 the output produced by the proportional term is 100%. With an error of 100% and I = 1.000 the output

To enable the PID controller the drive must be OK/healthy (Pr 10.01 = 1) and the PID enable (Pr 14.08) must be one. If the option enable source
(Pr 14.09) is 00.00 or routed to a non-existent parameter the PID controller is still enabled provided Pr 10.01 = 1 and Pr 14.08 = 1. If the optional
enable source (Pr 14.09) is routed to an existing parameter the source parameter must be one before the PID controller can be enabled. If the PID
controller is disabled the output is zero and the integrator is set to zero.

If Pr 14.18 = 0, the upper limit (Pr 14.13) defines the maximum positive output for the PID controller and the lower limit (Pr 14.14) defines the
minimum positive or maximum negative output. If Pr 14.18 = 1, the upper limit defines the maximum positive or negative magnitude for the PID
controller output. When any of the limits are active the integrator is held.
The value written to the destination parameter is (PID controller output x scaling) + PID main reference.
When this parameter is set to 0 the integrator operates normally. Setting this parameter to 1 will cause the integrator value to be held. Setting this
parameter does not prevent the integrator from being reset to zero if the PID controller is disabled.

5.17 Menus 15, 16 and 17: Solutions Module slots
Pr x.00 and Pr x.01 are always present in menus 15, 16 and 17. Pr x.01 indicates which type of module is present (0 = no module installed). When a
module is installed the drive provides the relevant menu (menu 15 for slot 1, 16 for slot 2 and 17 for slot 3) depending on the Solutions Module
installed. The possible categories are shown below.
Most modules include a processor and parameters are updated by the processor in the Solutions Module. However, dumb modules do not contain a
processor and all parameters are updated by the drive processor. Dumb Solutions Modules are SM-Encoder Plus, SM-Encoder Output Plus, SM-
Resolver and SM-I/O Plus.
Dumb Solutions Module parameters are read/written by the drive background task or at the combined update time for time critical parameters. The
combined update time depends on the number and type of dumb Solutions Modules installed to the drive. For each Solutions Module the update rate
of these parameters is specified as 4ms, 8ms, etc. The combined update time is the total of the update times for all dumb Solutions Modules installed.
For example, if a module with 4ms update time and a module with 8ms are installed to the drive, then the combined update time for the time critical
parameters of each module is 12ms.
In the parameter tables the update time added by the type of module is given, for example 4ms for the SM-Encoder Plus or 8ms for the SM-I/O Plus.
When parameters are saved by the user in the drive EEPROM the option code of the currently installed module is saved in EEPROM. If the drive is
subsequently powered-up with a different module installed, or no module installed where a module was previously installed, the drive gives a Slot.dF
trip. The menu for the relevant slot appears for the new module category with the default parameter values for the new category. The new parameters
values are not stored in EEPROM until the user performs a parameter save.

5.17.1 SM-Universal Encoder Plus
The Solutions Module checks for various errors as shown below.
Table 5-13 Solutions Module error status values for SM-Universal Encoder Plus
+These trips can be enabled/disabled by Pr x.17
1. If the terminations are not enabled on the A, B or Z inputs the wire break system will not operate. (Note that as default the Z input terminations are
disabled to disable wire break detection on this input).
2. Phase error for a servo type encoder is to detect that the incremental pulses have been counted incorrectly. The error is detected if the
incremental position moves by 10°C with respect to the position defined by the UVW commutation signals. The trip is initiated if the error is
detected for 10 consecutive samples.
3. Phase error for SINCOS encoders with comms is detected by interrogating the encoder every second via comms to compare the incremental
position determined from the sine waves with the incremental position via comms. If the error is Š 10×C for 10 consecutive samples the trip is
initiated.
Encoder initialisation will occur when trips 1 to 8 are reset. This causes an encoder with comms to be re-initialized and auto-configuration to be
performed if selected.
It is important that a break in the connections between the drive and the position feedback device can be detected. This feature is provided either
directly or indirectly as listed.
When the drive is reset this parameter is cleared for the relevant Solutions Module

Wire break detection is difficult with these devices. However, if power supply monitoring is enabled the drive will be
looking for a one at the start of the message and a zero to indicate that the power supply is okay. If the clock stops
or the data line is disconnected the data input to the drive may stay in one state or the other and cause a trip.

The new parameters values are not stored in EEPROM until the user performs a parameter save. When parameters are saved by the user in the drive
EEPROM the option code of the currently installed Solutions Module is saved in EEPROM. If the drive is subsequently powered-up with a different
Solutions Module installed, or no Solutions Module installed where one was previously installed, the drive gives a Slot.dF trip

When operating with an Issue 3 SM-Universal Encoder Plus, the software must be of version 03.xx.xx. When operating with an Issue 4 SM-Universal
Encoder Plus, the software must be of version 04.xx.xx.
Failure to comply with the above can result in Solutions Module failure.
Provided the set-up parameters for the position feedback are correct this parameter shows the speed in rpm, this parameter is filtered to give a
readable indication of speed.

These parameters give the position with a resolution of 1/232
Provided the set-up parameters are correct, the position is always converted to units of 1/232

Example:
A 1024 line digital encoder produces 4096 counts per revolution, and so the position is represented by the bits in the shaded area only.
When the feedback device rotates by more than one revolution, the revolutions in Pr x.04 increment or decrement in the form of a sixteen bit roll-over
counter. If an absolute position feedback is used the position is initialized at power-up with the absolute position.
If a linear encoder is used the turns information is used to represent the movement by the number of poles defined by Pr 5.11. Therefore if the number
of poles is set to two, one revolution is the movement by one pole pitch.
It may be required that Pr x.04, Pr x.05 and Pr x.06 are reset to zero this can be carried out by changing the encoder type Pr x.15 with all counters
being reset.
An incremental digital encoder may have a marker channel and when this channel becomes active (rising edge in the forward direction and falling
edge in reverse) it may be used to reset the encoder position and set the marker flag (Pr x.07 = 0), or just to set the marker flag (Pr x.07 = 1). When
the position is reset by the marker, Pr x.05 and Pr x.06 are reset to zero.
The marker flag is set each time the marker input becomes active, but it is not reset by the Solutions Module, and so this must be done by the user.
The marker function only operates when Ab, Fd, Fr, Ab.SErvo, Fd.SErvo, Fr.SErvo, SC.SErvo type encoders are selected with Pr x.15.
This parameter has a different function depending on the type of encoder selected with Pr x.15 and Pr x.16.
Ab, Fd, Fr, Ab.SErvo, Fd.SErvo, Fr.SErvo, SC, SC.SErvo
It is sometimes desirable to mask off the most significant bits of the revolution counter with these types of encoders. This does not have to be done for
the drive to function correctly. If Pr x.09 is zero the revolution counter (Pr x.04) is held at zero. If Pr x.09 has any other value it defines the maximum
number of the revolution counter before it is reset to zero.
Example, if Pr x.09=5, then Pr x.04 counts up to 31 before being reset. If Pr x.09 is greater than 16 the number of turns bits is 16 and Pr x.04 counts
up to 65535 before being reset.
SC.HiPEr, SC.EndAt, SC.SSI and Pr x.16 = 1 or 2 (Rotary encoder)
Pr x.09 must contain the number of bits in the comms message used to give the multi-turn information. For a single turn comms encoder, Pr x.09 must
be set to zero. As well as setting the number of comms turns bits this parameter also sets up a mask on the turns displayed in Pr x.04 as described
above.
With SC.HiPEr or SC.EndAt encoders it is possible for this parameter to be obtained automatically from the encoder (see Pr x.18). If Pr x.09 is greater
than 16 the number of turns bits is 16.
SC.HiPEr, SC.EndAt, SC.SSI and x.16 = 0 (Linear encoder)
When a linear encoder is selected no mask is placed on the turns information displayed in Pr x.09, and so this parameter always displays the turns
information as a full 16 bit value with a maximum of 65535. Linear SINCOS encoders with comms are normally specified with a length for each sine
wave period and the length for the least significant bit of the position in the comms message. Pr x.09 should be set up with the ratio between these
two lengths so that the Solutions Module can determine the encoder position during initialisation.
The Linear encoder comms to sine wave ratio is defined as follows:
With SC.HiPEr or SC.EndAt encoders it is possible for this parameter to be obtained automatically from the encoder (see Pr x.18).
EndAt, SSI
Pr x.09 must contain the number of bits in the comms message used to give the multi-turn information. For a single turn comms encoder, Pr x.09
must be set to zero. As well as setting the number of comms turns bits this parameter also sets up a mask on the turns displayed in Pr x.04 as
described above. It is possible for this parameter to be obtained automatically from the encoder (see Pr x.18). If Pr x.09 is greater than 16 the number
of turns bit is 16.

It should be noted that if the Pr x.19 the Feedback Filter is used where, the speed feedback is provided by either an EndAt or SSI encoder connected
directly to the module, it is necessary for the encoder to provide at least 6 bits of turns information. This is not a problem when the position is defined
by the absolute position from the encoder at initialisation and then accumulated delta positions (Pr x.16 = 0), however, if the absolute position is taken
directly from the encoder (Pr x.16 > 0) the encoder must provide at least 6 bits of turns information.
If the Feedback filter Pr x.19 is not used turns information from the encoder is not required.
When Ab, Fd, Fr, Ab.SErvo, Fd.SErvo, Fr.SErvo or SINCOS signals are used the equivalent number of encoder lines per revolution must be set-up
correctly in Pr x.10 to give the correct speed and position feedback. This is particularly important if the encoder is selected for speed feedback with Pr
3.26. The equivalent number of encoder lines per revolution (ELPR) is defined as follows.
For any type of linear encoder one revolution is the motor pole pitch multiplied by the number of poles set up in Pr 5.11.
Ab, Fd, Fr, Ab.SErvo, Fd.SErvo and Fr.SErvo
The incremental signal frequency should not exceed 500kHz.
SC.HiPEr, SC.EndAt, SC.SErvo, SC and SC.SSI
The absolute maximum sine wave signal frequency is 166kHz (version 3.x.x) 250kHz (version 4.x.x).
The encoder port is designed to give 10 bits of interpolation resolution at 115kHz. The resolution is reduced at frequencies higher than 115kHz and at
peak to peak differential voltages less than 1 volt. The total resolution in bits per revolution is the ELPR plus the number of bits of interpolated
information.
The table below shows the number of bits of interpolated information at different frequencies and with different voltage levels at the drive encoder
port.
200kHz and 250kHz are not available with hardware versions less than 4.x.x
If the position feedback device is a rotary SINCOS encoder with comms the position supplied via comms gives a number of counts per revolution that
is a power of two and the resolution is defined by the single turns comms bit (Pr x.11).
When Pr x.11 is adjusted an "Initialisation failed - 7" trip is produced, because the encoder requires re-initialisation.
EndAt, SSI
Where encoder comms alone is used as position feedback, the equivalent lines per revolution (Pr x.10) is not used in setting up the encoder interface.
It is possible for the drive to set up this parameter automatically from information obtained from an EndAt encoder (see Pr x.18).
The equivalent lines per revolution in Pr x.10 can be divided where required using Pr x.46 line per revolution divider.
Example 128.123 lines per revolution would be set as 128123 in Pr x.10 and 100 in Pr x.46 giving 128123 / 1000 = 128.123
Where encoder comms is used for initial setting of absolute position (SC.HiPEr or SC.EndAt), the comms resolution in bits must be set correctly,
either by the user or the drive (see Pr x.18), in Pr x.11. The comms resolution may be higher than the resolution of the sine waves per revolution.

SC.HiPEr, SC.EndAt, SC.SSI and x.16 = 0 (Linear encoder)
Pr x.11 must be set up to the total number of bits representing the whole encoder position in the comms message.
This parameter is not used with linear SC.HiPEr encoders as the number of bits used to represent the whole position is always 32.
EndAt, SSI
Pr x.11 must be set to the number of bits used to represent one revolution of the encoder.
Although Pr x.11 can be set to any value from 0 to 32, if the value is less than 1, the resolution is 1 bit. Some SSI encoders (SC.SSI or SSI) include a
power supply monitor alarm using the least significant bit of the position. It is possible for the drive to monitor this bit and produce a trip 6 if the power
supply is too low (see Pr x.17). If the encoder gives this information the comms resolution should be set up to include this bit whether it is being
monitored by the Solutions Module or not.
It is possible for the drive to set up this parameter automatically from encoder information via Hiperface or EndAt interfaces (see Pr x.18).
The motor thermistor if connected to the Solutions Module for temperature monitoring is enabled through this parameter.
Refer to the SM-Universal Encoder Plus User Guide for full details.
The encoder supply voltage present on the SM-Universal Encoder is defined by this parameter as 0(5V), 1(8V), or 2(15V).
This parameter defines the baud rate for the encoder comms when using encoders with either SSI or EndAt interfaces. A fixed baud rate of 9600 is
used with Hiperface encoders and this parameter has no effect. Any baud rate can be used when encoder comms is used with a SINCOS encoder to
obtain the absolution position during initialisation.
When the encoder comms is used and the position within one turn can be obtained in 30μs and the rest of the message including CRC within a further
30μs (60μs total) the encoder position for control is taken during each level 1 interrupt (fast sampling).
If either of these conditions is not met the position is taken every 250μs. The position feedback used for speed control is taken every 250μs
irrespective of the encoder message time. The comms message must not be longer than 200μs otherwise position feedback errors will occur.
Compensation based on the speed over the previous 250μs is applied to correct the position so that it appears to have been taken at the encoder
datum used by all other encoder types.
If fast sampling is used the control position used to define the drive reference frame is obtained every current/torque control sample (switching
frequency selected dependant). If slow sampling is used the control position is obtained every 200μs.
When fast sampling is used the delay introduced into the control system by the encoder is less, and so a higher control system bandwidth will be
possible (position values from the encoder could be used in a position control system).
Also refer to the SM-Universal Encoder Plus User Guide, for further detailed information on operation with encoder serial comms.

The following encoders can be connected to the SM-Universal Encoder Plus.
3, Ab.SErvo: Quadrature incremental encoder with commutation outputs, with or without marker pulse
4, Fd.SErvo: Incremental encoder with frequency, direction and commutation outputs, with or without marker pulse
5, Fr.SErvo: Incremental encoder with forward, reverse and commutation outputs, with or without marker pulse
U, V, W commutation signals are required with an incremental type encoder when used with a servo motor.
The UVW commutation signals are used to define the motor position during the first 120° electrical rotation after the drive is powered-up or the
encoder is initialized.
6, SC: SinCos encoder with no serial communications
This type of encoder can be used for motor control in closed-loop vector mode or servo mode. In servo mode a phasing test must be performed after
every drive power-up or encoder trip.
7, SC.HiPEr: Absolute SinCos encoder using Stegmann 485 comms protocol (HiperFace).
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. The Solutions Module can
check the position from the sine and cosine waveforms against the internal encoder position using serial communications and if an error occurs the
Solutions Module trips the drive. Additional communications with the encoder is possible.
8, EndAt: Absolute EndAt only encoder
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. Additional communications with
the encoder is not possible.
9, SC.EndAt: Absolute SinCos encoder using EndAt comms protocol
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. The Solutions Module can
check the position from the sine and cosine waveforms against the internal encoder position using serial communications and if an error occurs the
drive trips. Additional communications with the encoder is possible.
10, SSI: Absolute SSI only encoder
This type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. Additional communications with
the encoder is not possible. SSI encoders use either gray code or binary format which can be selected with Pr x.18. Most SSI encoders use 13 bit
single turn position information, and so Pr x.11 should normally be set to 13. If the single turn resolution of the encoder is lower then the least
significant bits of the data are always zero. Some SSI encoders use the least significant bit to show the status of the encoder power supply. In this
case the single turn position resolution should be set to include this bit, but the Solutions Module should be set up to monitor it via Pr x.17. Some SSI
encoders use a right shifted format where the unused single turn position bits are removed instead of being set to zero. For these encoders the single
turn position resolution should be set to the number of bits used for the single turn position.
If an Absolute SSI only encoder is used with a data transfer rate of >30μs timing problems may occur, resulting in speed feedback instability.
11, SC.SSI: SinCos encoder using SSI comms protocol
This type of encoder gives absolute position and can be used for motor control in Closed-loop vector or Servo modes. The drive can check the
position from the sine and cosine waveforms against the internal encoder position using serial communications and if an error occurs the drive trips.
12, SC.SErvo: SinCos encoder with UVW communication outputs
The type of encoder gives absolute position and can be used for motor control in closed-loop vector or servo modes. U, V, W commutation outputs
are required with a SinCos type encoder when used with a servo motor. The U, V, W commutation outputs are used to define the motor position
during the first 120° electrical rotation after the drive is powered-up or the encoder is initialized.
The following should be noted:
It should be noted that all SINCOS encoders and encoders using communications must be initialized before their position data can be used. The
encoder is automatically initialized at power-up or when the initialisation parameter (Pr 3.47) is set to 1.
In addition to using all the above encoders types as position feedback from a motor, they may be used as a position reference for the drive position
controller or a position controller application in an Solutions Module etc. When a comms only encoder interface is used, it is possible to instantly
change the position by a large number of turns. This can cause a position error in the drive if the change over a 250μs period appears to produce a
speed of greater than 40,000rpm. Therefore if the EndAt or SSI interface is used to provide a reference the change over each 250μs sample must not
exceed 0.16 turns. If the position is incorrect because the change is too large this can be corrected by re-initializing the encoder interface, Pr 3.47.
If an SSI encoder is used, but is not powered from the drive, and the encoder is powered up after the drive it is possible that the first change of
position detected could be big enough to cause the problem described above. This can be avoided if the encoder interface is initialized via Pr 3.47
enabled, Pr 3.40.
Trips can be enabled/disabled using Pr 3.40 as follows.
This will ensure that the drive remains tripped until the encoder is powered up and the action of resetting the trip will re-initialize the encoder interface.

SC.HiPEr, SC.EndAt, SC.SSI - Rotary encoder select
If Pr x.16 is set to 1 or 2 the encoder is a rotary encoder and the following applies
1. Pr x.09 defines the number of turns bits in the comms message from the encoder and a mask is applied to Pr x.04 to remove turns bits in excess
of those provided in the encoder comms position.
2. Pr x.11 defines the number of comms bits used to define a single turn.
If Pr x.16 is set to 0 the encoder is a linear encoder and the following apply:
1. Pr x.09 defines the ratio between the length of a sine wave period and the length of the least significant comms bit.
2. No mask is applied to the turns displayed in Pr x.04.
3. Pr x.11 defines the number of comms bits used to give the whole position value.
If the position feedback device is SC.HiPEr or SC.EndAt it is possible for the drive to set up this parameter automatically from information obtained
from the encoder (see Pr x.18).
EndAt, SSI - Comms only encoder mode
If this parameter is set to 1 or 2 the drive always takes the complete absolute position for these comms only type encoders. The turns (Pr x.04),
position (Pr x.05) and fine position (Pr x.06) will be an exact representation of the position from the encoder.
If the encoder does not provide 16bits of turns information, the internal representation of the turns used by the position controller in Menu 13 and
functions within the SM-Applications Module such as the Advanced Position Controller, rolls over at the maximum position value from the encoder.
This jump in position is likely to cause unwanted effects.
EndAt
The EndAt format includes a CRC that is used by the drive to detect corrupted data, and so if the position data has been corrupted the drive uses the
previous correct data until new uncorrupted data is received.
If this parameter is set to 0 the drive only takes the absolute position directly from the encoder during initialisation. The change of position over each
sample is then used to determine the current position. This method always gives 16 bits of turns information that can be used without jumps in
position by the position controller in Menu13 and SM-applications modules etc. This method will only operate correctly if the change of position over
any 250μs period is less than 0.5 of a turn, or else the turns information will be incorrect. The turns can then only be corrected by re-initializing the
encoder.This problem should not occur with EndAt encoders because three consecutive corrupted messages at the slowest sample rate (i.e. 250μs)
would be required even at the maximum speed of 40,000rpm before the change of position would be the required 0.5 turns to give possible corruption
of the turns information. If three consecutive messages with CRC errors occur this will cause the drive to produce an EnC5 trip. The drive can only be
re-enabled after the trip is reset which will re-initialize the encoder and correct the absolute turns
SSI
As the SSI format does not include any error checking and it is not possible for the drive to detect if the position data has been corrupted. The benefit
of using the absolute position directly from an SSI encoder is that even if the encoder communications are disturbed by noise and position errors
occur, the position will always recover the correct position after the disturbance has ceased.
Under normal operating conditions and at a maximum speed of 40,000rpm the maximum change of position is less than 0.5 turns, however, if noise
corrupts the data from an SSI encoder it is possible to have apparent large change of position, and this can result in the turns information becoming
and remaining corrupted until the encoder is re-initialized.
If an SSI encoder is used, but is not powered from the drive, and the encoder is powered up after the drive, it is possible that the first change of
position detected could be large enough to cause the problem described above. This can be avoided if the encoder interface is initialized via Pr 3.47
enabled (see Pr x.17). This will ensure that the drive remains tripped until the encoder is powered up and the action of resetting the trip will reinitialise
the encoder interface.

Trips can be enabled/disabled using Pr x.17 as follows:
The binary sum defines the level of error detection as below:
If the SSI power supply bit monitor feature is enabled, ensure that this has been configured for an encoder setup Pr x.09, Pr x.11.
In order for the phase error detection to function correctly the LPR of the SC.HiPEr, SC.EndAt and SC.SSI encoder must be greater than 9 x number
of motor poles (e.g 54 for a 6 pole servo motor).
Trip suppression mode
If bit 3 is set and #3.26 does not select this option module as the feedback device, trips 1 to 6 (encoder trips during normal running) will not trip the
drive. They will still be serviced locally, for example the power supply will be turned off if an overload condition occurs.
When this mode is active and a trip occurs, the option module will set x.49 (freeze encoder position) to alert the user that a trip has been suppressed.
The trip number will still be written to x.50, but a drive trip request will not be made (Slx.Er). The action of resetting the drive resets the flag (x.49) and
the trip (x.50).
SC.HiPEr, SC.EndAt, EndAt
When an SC.HiPEr, SC.EndAt or EndAt encoder is being used, the Solutions Module will interrogate the encoder on power-up. If Pr x.18 is set to one

resulting parameter values are out of range the Solutions Module initiates a trip 7 or 12 to 16 trip to prompt the user to enter the information. The

Linear EndAt encoders
The comms resolution is set to the number of bits required for the whole position within the position data messages from the encoder. The linear
encoder comms to sine wave ratio is calculated from the sine wave period and LS comms bit length. The encoder does not give the equivalent lines
per rev directly, but gives the length of a sinewave period in mm. Therefore the Solutions Module uses the pole pitch (Pr 5.36) and the number of
motor poles (Pr 5.11) for the motor to calculate the equivalent lines per revolution.
ELPR = Pole pitch x Number of motor pole pairs / Length of a sinewave
Normally the Number of motor poles will be set to 2, and so:
ELPR = Pole pitch / Length of a sinewave
It should be noted that the equivalent lines per revolution parameter is only updated when auto-configuration occurs, i.e. when the encoder is
initialized, and that it uses the pole pitch for the active motor. The value for Pole pitch x Number of motor pole pairs is limited to 655.35mm by the
drive. If the pole pitch is left at its default value of zero which would give ELPR = 0, or the result of the calculation is over 50000, the drive will initiate
an Enc15 trip.
The ELPR divider (Pr x.46) is returned to 1 if auto-configuration completes correctly.
Hiperface encoders
The Solutions Module can recognize any of the following devices: SCS 60/70, SCM 60/70, SRS 50/60, SRM 50/60, SHS 170, LINCODER, SCS-KIT
101, SKS36, SKM36, SEK52 and SEK53. If the Solutions Module cannot recognize the encoder type it will initiate 12 trip.
The ELPR divider (Pr x.46) is returned to 1 if auto-configuration completes correctly.
SC.SSI, SSI
SSI encoders normally use gray code data format. However, some encoders use binary format that may be selected by setting this parameter to one.
0 = 0ms, 1 = 1ms, 2 = 2ms, 3 = 4ms, 4 = 8ms, 5 = 16ms
A sliding window filter may be applied to the feedback. This is particularly useful in applications where the feedback is used to give speed feedback
for the speed controller and where the load includes a high inertia, and so the speed controller gains are very high. Under these conditions, without a
filter on the feedback, it is possible for the speed loop output to change constantly from one current limit to the other and lock the integral term of the
speed controller.
It should be noted that if this filter is used where the speed feedback is provided by an EndAt or SSI encoder connected directly to the module, it is
necessary for the encoder to provide at least 6 bits of turns information. This is not a problem when the position is defined by the absolute position
from the encoder at initialisation and then accumulated delta positions (Pr x.16=0), however, if the absolute position is taken directly from the encoder
(Pr x.16 > 0) the encoder must provide at least 6 bits of turns information. If this filter is not used (i.e. Pr x.19=0) turns information from the encoder is
not required.
The speed filter can be used to reduce resolution "stepping" problems with low line per revolution encoder inputs when used through the feedback
reference router also.
The resistance value of the thermistor input can be seen in Pr x.21. The motor thermistor resistance value shown in Pr x.21 is shown in 0.1% of 10kΩ
units. The position feedback when used as a reference can be viewed here.

The feedback reference scaling is applied as follows:
The position feedback can be used as a reference for any unprotected parameter and is the output from the speed filter (Pr x.19). This value is also
displayed in Pr x.03 after further filtering to aid readability.
The filtered reference is converted to percentage of the maximum position feedback reference (Pr x.20) and displayed via the feedback reference (Pr
x.21). This value is to the nearest tenth of a percent and is limited to ± 100.0%. The limited percentage value is then scaled by the feedback reference
scaling (Pr x.22). This scaled value is also to the nearest tenth of a percent and is also limited to ± 100.0%. The value written to the destination
parameter is converted to a percentage of the full-scale value of the destination (Pr x.23) to the nearest tenth of a percent.
The destination is updated every 4ms.
If the destination for the feedback is the hard speed reference (Pr 3.22), a shortcut facility is provided in the drive. In order to invoke this facility, the
maximum feedback reference (Pr x.20) must be set to the maximum currently used for the hard speed reference and the scaling parameter (Pr x.22)
must be set to 1.0000. The destination is updated every 250μs and a value in rpm is written to Pr 3.22 every 4ms for indication only.
If the destination is default or invalid (non-existent or protected) Pr x.21 displays the motor thermistor resistance in 0.1% of 10kΩ units. This operates
even if Pr x.12 (thermistor enable) is not enabled allowing the user to design their own characteristic without trips using the threshold detector.
Example
Speed is 200rpm Pr x.20 is 400rpm so Pr x.21 shows 50%. Pr x.22 is 0.500 so the final percentage value is 25%. The destination is a 16 bit bipolar
parameter which therefore will have 25% * (2^15) = 8192 written to it.
Effect of encoder resolution
A 1024 line encoder as the input produces 4096 counts per revolution. The resolution is one count per 250μs. As one count is 1/4096th of a
revolution, the speed resolution is actually 58.8rpm.
A 4096 line encoder as the input produces 16384 counts per revolution. As one count is 1/16384th of a revolution, the speed resolution is actually
14.6rpm.
To compensate for the resolution of one count per 250μs the speed filter can be used. For example a filter of 4ms divides the resolution by 16, but
could affect the performance of any control loop.
Effect of percentage resolution
Destinations other than the hard speed reference (Pr 3.22) will be rounded to the nearest tenth of a percent. This would give a minimum resolution of
1 rpm if the destination maximum were 1000.0rpm for example.
The simulated encoder output (incremental), Ab, Ab.L, Fd, Fd.L can be scaled using the above parameter.

An encoder simulation output can be generated from any parameter as a source as defined by Pr x.24 (00.00 disables encoder simulation). Although
any parameter can be used, the source parameter is assumed to be a 16 bit position value in the form of a roll-over counter. Therefore only
parameters with a range of -32768 to 32767 or 0 to 65535 are normally used. The marker is simulated when the source rolls over or under.
The sources update rate should be considered when setting up a simulated encoder output, for example with Pr x.05 as the source this has an
update rate of 250μs (shortcut in software) with Pr x.30 this has an update rate of 4ms (averaging is applied for the simulated encoder output in this
example to prevent “stepping effects” being seen on the simulated encoder output).
When the Solutions Module is connected to a high precision encoder (i.e. SinCos) and the source has been selected as the internal position (Pr x.05),
the resolution can be increase to a 24 bit position value by setting Pr x.27 to a one.
Pr x.28 defines the output mode for simulated encoder output as follows.
Modes 6 and 7 are only available with the drive software versions 01.07.00 onwards, and issue 4 SM-Universal Encoder Plus.
If the source is not the feedback device, the simulator waits until all feedback devices are initialized before the starting to output. The wait for
initialisation does not occur if the drive software version is less than V01.08.00.
Also refer to the SM-Universal Encoder Plus User Guide for further detailed information.

This position is taken from the position feedback device and is not affected by the marker or the freeze inputs.
Each time the marker becomes active the non-marker position values (Pr x.29 to Pr x.31) are sampled and stored in Pr x.32 to Pr x.34.
The freeze input to the SM Universal Encoder Plus can take the following forms
• A 485 signal through the encoder marker simulation output pins
• A 24V signal on the freeze 24V input
• A signal on the internal drive and slot freeze line generated by another Solutions Module.
The selection of which mode used is dependent on the value of Pr x.38. The default is 1 that corresponds to only the 24V input to this Solutions

Modes 4 to 7 are only available with the drive software versions 01.07.00 onwards and issue 4 SM-Universal Encoder Plus.
Each time the freeze input on the Solutions Module becomes active the non-marker position (Pr x.29 to Pr x.31) is stored in Pr x.35 to Pr x.37 and the
freeze flag (Pr x.39) is set. The freeze flag is not reset by the module and must be reset by the user. No other freeze conditions will be trapped if the
flag is set.
This parameter enables the Solutions Module to pass the freeze signal internally to the drive and other slots so that when a freeze occurs on the
Solutions Module the main drive position and/or other slots can also be frozen.
When Pr x.41 = 0 freeze occurs on the rising edge of the freeze input. When Pr x.41 = 1 freeze occurs on the falling edge of the freeze input.
In SINCOS mode (6) ONLY with no comms or commutation inputs, the internal differential Sin signal value is written to Pr x.42 as an unsigned
number.
A value greater then 32768 in Pr x.42 requires the user to minus 65536 to get the negative result. 0.675V approximate differential input produces
16384 (the maximum). The value given is quantized to 32 as the ADC produces a 10bit value with the outputs most significant bit in bit14 of the value
in Pr x.42.
0.5V gives approximately 12192 and 0.25V gives approximately 6112.
In AB.SErvo (3), FD.SErvo (4) or FR.SErvo (5) mode, the value in Pr x. 42 is obtained from the rules below. This permits the user to determine the
current segment and status of the commutation inputs (U high equals logic 1, U low equals logic 0):
Pr x.42 = 1000 * segment + 100 * U state + 10 * V state + W state
Example
If the commutation inputs equalled 110 (which is the 2nd segment) then Pr x.42 would be set to 2110.
Segment 9 means that the current commutation input is invalid.
All other modes follow the description for Pr x.44.
This parameter has no effect for SC.SErvo encoders.

In SINCOS mode (6) ONLY with no comms or commutation inputs, the internal differential Cos signal is written to this parameter as an unsigned
number.
A value greater then 32768 in Pr x.42 requires the user to minus 65536 to get the negative result.
In AB.SErvo (3), FD.SErvo (4) or FR.SErvo (5) mode, Pr x.43 equals zero.
All other modes follow the description for Pr x.44.
This parameter has no effect for SC.SErvo encoders.
If Pr x.44 is zero the drive can check the position derived with the sine and cosine waveforms from a SinCos encoder via serial communications.
If Pr x.44 is set to one the checking is disabled and encoder comms is available via the transmit and receive registers. The transmission system can
be used to communicate with encoders provided the mode is either SC.HiPEr or SC.EndAt.
For further detailed information refer to the SM-Universal Encoder Plus User Guide.
At power-up Pr x.45 is initially zero, but is set to one when the encoder connected to position module has been initialized. The drive cannot be
enabled until this parameter is one.
If the encoder power-supply is lost, or the encoder type parameter is changed for an encoder connected to a Solutions Module, and the encoder type
is SC, SC.HiPEr, SC.EndAt or EndAt the encoder will no longer be initialized. When an encoder is no longer initialized Pr x.45 is reset to zero and the
drive cannot be enabled. The encoder may be re-initialized, provided the drive is not active, by setting Pr 3.47 to one. Pr x.45 is automatically reset to
zero when the initialization is complete.
The LPR divider Pr x.46 is used to scale the equivalent lines per revolution in Pr x.10 of incremental and SinCos encoders, without comms, on rotary
motors, and all but comms only encoders on linear motors. (Servo encoders must have the same number and pitch of poles as the motor).
The equivalent line per revolution parameter (Pr x.10) is divided by the value in Pr x.46. This can be used when an encoder is used with a linear
motor where the number of counts or sine waves per pole is not an integer.
Example
128.123 lines per revolution would be set as 128123 in Pr x.10 and 1000 in Pr x.46 giving:
128123 / 1000 = 128.123. If the value is less than 1, the value used will be 1.
When using SinCos encoders with comms, the comms and SinCos positions must be aligned. The comms position resolution may be a multiple of the
analog position resolution. When a linear encoder type has been selected (Pr x.16 = 0) the value in Pr x.09 is this multiple.
The motor pole pitch used to configure EndAt and Hiperface encoders is that of the currently selected motor map.
When setting larger values in Pr x.10 when the Solutions Module is the main feedback device, the drive will limit the maximum speed, which in turn
limits the maximum of some of the drive parameters such as Pr 1.06 and Pr 1.21. If the overall value of the LPR after division is low once more, the
parameters that have been limited will not return to their original values and may need to be increased. An ELPR of 10,000 gives a maximum speed
of 3000rpm.
When operating with an Incremental plus commutation (absolute encoder), Ab.SErvo, Fd.SErvo, Fr.SErvo or SC.SErvo this parameter should remain
at default (Pr x.46 = 1).

If Pr x.49 is set to one, Pr x.04, Pr x.05 and Pr x.06 are not updated. If this parameter is zero, Pr x.04, Pr x.05 and Pr x.06 are updated normally.
The error status is provided so that the only one option error trip is required for each Solutions Module slot. If an error occurs, the reason for the error
is written to this parameter and the drive may produce a ‘SLX.Er’ trip, where x is the slot number. A value of zero indicates that the Solutions Module
has not detected an error, a non-zero value indicates that an error has been detected. (See Table 5-13 on page 253 for the meaning of the values in
this parameter for the SM-Universal Encoder Plus). When the drive is reset, this parameter is cleared for the relevant Solutions Module.
This Solutions Module includes a temperature monitoring circuit. If the PCB temperature exceeds 90°C (94°C V03.02.00 or later), the drive fan is
forced to operate at full speed (for a minimum of 10s). If the temperature falls below 90°C (94°C V03.02.00 or later), the fan can operate normally
again. If the PCB temperature exceeds 100°C, the drive is tripped and the error status is set to 74.
The SM-Universal Encoder Plus includes a processor with software. The software version is displayed in Pr x.02 and Pr x.51 in the form Pr x.02 =
xx.yy and Pr x.51 = zz.
Where:
xx specifies a change that affects hardware compatibility
yy specifies a change that affects product documentation
zz specifies a change that does not affect the product documentation
When a Solutions Module is installed that does not contain software, both Pr x.02 and Pr x.51 appear as zero.
When operating with an Issue 3 SM-Universal Encoder Plus Solutions Module, the software must be V.03.xx.xx. When operating with an Issue 4 SM-
Universal Encoder Plus Solutions Module, the software must be V.04.xx.xx
Failure to comply with the above can result in Solutions Module failure.

When an SM-Resolver is installed the user parameter menu for the module contains all the parameters for a position feedback category Solutions
Module. However, all parameters are not used by this Solutions Module. In the descriptions below only the parameters used by the module are
described.
The update time for some functions are affected by the number of dumb Solutions Modules installed to the drive. The update time for these functions
is the sum of the update times for all dumb Solutions Modules installed to the drive, called the combined update time. The update time for the SM-
Encoder plus and SM-Resolver modules is 4ms, and the update time for the SM-I/O plus is 8ms.
If the module is selected for motor control the position feedback can be used as the reference or feedback source for the position controller within the
drive or with any application within a SM-Applications module. However, if the module is not selected for motor control the speed (Pr x.03 is always
zero), and the maximum speed must be limited depending on the Solutions Module combined update time so that the resolver position does not
change by more than half an electrical revolution within the sample period. Therefore
Maximum speed (rpm) <0.5 x 60 / Combined update time / (Resolver poles / 2)
e.g with a combined update time of 4ms and a 2 pole resolver the maximum speed is 7500rpm. If this maximum speed is exceeded the resolver
position and freeze position will be incorrect.
Position/speed feedback update rate
If the module is selected for motor control position feedback then the position and speed parameters are updated as defined with each parameter, but
are available within the drive at a faster rate as shown below.
If the module is not selected for motor control position feedback the position and speed are updated as defined with the appropriate parameters.

Pr x.04 and Pr x.05 give the position with a resolution of 1/216
be relevant depending on the resolution of the feedback device. For example if 10 bit resolution is selected the resolver produces 4,096 counts per
counter.
The internal update time for the position Pr x.05 when used as feedback runs at level 1, this being switching frequency dependant as follows.
The internal update time for the speed Pr x.03 when used as feedback runs at level 2 as follows.
This parameter relates to the equivalent lines per revolution of a quadrature encoder that would provide same resolution of feedback. This parameter
should only be set to 256 (10 bit resolution), 1,024 (12 bit resolution) or 4,096 (14 bit resolution). If the parameter is set to any other value the drive
assumes the following: 32 to 256 = 256; 257 to 1,024 = 1,024; 1,025 to 50,000 = 4,096. If the drive is operating in Closed-loop vector or Servo modes
and the resolver is selected to provide speed feedback for the drive (see Pr 3.26) then variable maximum SPEED_LIMIT_MAX is defined in the
following table.
It should be noted that for a 2 pole resolver that this parameter defines the resolution over one mechanical revolution, but for a resolver with 4, 6 or 8
poles the resolution defines the resolution over an electrical revolution of the motor. For example with a 6 pole resolver (and 6 pole motor) the
resolution is over 1
/3 of a mechanical revolution.

The excitation level can be controlled for use with 3:1 ratio resolvers (Pr x.13 = 0), or 2:1 ratio resolvers (Pr x.13 = 1 or 2).
Resolvers with the following numbers of poles can be used with the Solutions Module.

2: 6POLE
3 to 12: 8POLE
A 2 pole resolver can be selected as drive speed feedback with a motor with any number of poles. A resolver with a number of poles greater than 2
can only be used with a motor where the number of revolver poles divides exactly into the number of motor poles i.e. a 4 pole resolver with an 8 pole
motor.

Pr x.24 = Pr x.05
Encoder simulation output is derived from the resolver input via hardware. The resolution multiplier can be set up using Pr x.25 as shown in the table
below. The marker output is active when the resolver position is zero, therefore the marker pulse width is equivalent to one encoder count if the ratio
is 1, but is reduced if the ratio is less than 1.
Some ratios are not possible when the resolver resolution is reduced below 14 bits as shown in the table below.
Pr x.24 = Pr 3.29
Encoder simulation output is derived from the drive encoder port via hardware from the A, B and Z inputs. The drive encoder signals must be digital
and not SINCOS. No ratio is possible, therefore Pr x.25 has no effect.
If Pr x.24 has any value than those above the encoder simulation outputs are not active.

This Solutions Module does not have its own freeze input, therefore the freeze input must come from a SM-Applications or SM-Universal Encoder
Plus. The freeze data is processed every 4ms x number of dumb modules installed. If a freeze has occurred and the freeze flag (Pr x.39) is zero, the
position is stored in Pr x.36 and the freeze flag is set. The freeze flag must be reset by the user before the next freeze event is stored. This function is
only active with 2 pole resolvers.

The update time for some functions are affected by the number of dumb Solutions Modules installed to the drive. The update time for these functions
is the sum of the update times for all dumb Solutions Modules installed to the drive, called the combined update time. The update time for the SM-
Encoder Plus, SM-Encoder Output Plus and SM-Resolver modules is 4ms, and the update time for the SM-I/O Plus is 8ms.
Some functions with the SM-Encoder plus and SM-Encoder Output Plus modules do not function correctly if the update time is too long. The input
frequency should not exceed 500kHz, but in addition the number of encoder counts seen over one sample period should not exceed 32768. Provided
the frequency is within the 500kHz limit, the maximum count cannot be exceeded with Fd and Fr encoders with any sample time, or with Ab encoders
if the sample time is 16ms or less. If the sample time is 20ms then the maximum allowed frequency with Ab encoders is 409.6kHz.
Position/speed feedback update rate
If the module is selected for motor control position feedback then the position and speed parameters are updated as defined with each parameter, but
are available within the drive at a faster rate as shown below.
If the module is not selected for motor control position feedback the position and speed are updated as defined with the appropriate parameters.

An incremental digital encoder may have a marker channel and when this channel becomes active (rising edge in the forward direction and falling
edge in reverse) it may be used to reset the encoder position and set the marker flag (Pr x.07 = 0), or just to set the marker flag (Pr x.07 = 1). When
the position is reset by the marker, Pr x.05 is reset to zero.
The marker flag is set each time the marker input becomes active, but it is not reset by the drive, and so this must be done by the user.
When Ab, Fd, or Fr signals are used the equivalent number of encoder lines per revolution must be set-up correctly in Pr x.10 to give the correct
speed and position feedback. The equivalent number of encoder lines per revolution (ELPR) is defined as follows:
Although Pr x.10 can be set to any value from 0 to 50,000, there are restrictions on the values actually used as follows:
If Pr x.10 < 2, ELPR = 2. If Pr x.10 > 16,384, ELPR = 16,384. Otherwise, Pr x.10 is rounded down to the nearest value that is a power of 2, e.g. if
5,000 is set in Pr x.10, the drive actually uses 4,096
The encoder supply voltage for this Solutions Module is defined by this parameter as 0(5V), 1(8V), or 2(15V).
The following encoders can be connected to the SM-Encoder Plus.

16ms.
The encoder simulation system provides an encoder output with minimal delay from either the drive encoder (Pr x.24 = 3.29) or the encoder
connected to this option module (Pr x.24 equal to any other value). The drive encoder can be an incremental encoder (Ab, Fd, Fr, Ab.Servo,
Fd.Servo, Fr.Servo) or it can be a SINCOS encoder (SC, SC.Hiper, SC.EnDat or SC.SSI). If any other encoder types are selected the output is
undefined. If a SINCOS encoder is being used the encoder simulation is derived from the sine waves and does not include interpolation information.
The ratio between the change of encoder position and the change of encoder simulation output position is defined by Pr x.25. The table below shows
the possible ratios.

Pr x.28 selects the format of the encoder simulation output as shown in the table below.
The marker output is derived directly from the encoder simulation input source marker. The width of the marker pulse is not adjusted with the encoder
simulation ratio, but remains the same width as the input marker. If a mode without marker lock is selected then the relationship between the marker
position and the incremental signals is undefined. If a mode with marker lock is selected the incremental position is shifted when the first input marker
occurs so that with Ab mode the marker is aligned with A high and B high, and with Fd mode the marker is aligned with F high. Marker lock is required
when the system that is receiving the encoder simulation signals requires a defined relationship between the marker and the incremental signals.
Marker lock should not be used if the drive encoder equivalent lines per revolution (ELPR) is not a power of 2 or the ELPR of the encoder simulation
output is less than 1 after the divide ratio has been applied.
Pr x.29 and Pr x.30 are duplicates of Pr x.04 and Pr x.05 respectively and not affected by the marker or freeze inputs.
Each time the marker becomes active, the non-marker position values (Pr x.29 and Pr x.30) are sampled and stored in Pr x.32 and Pr x.33.

This Solutions Module does not have its own freeze input, therefore the freeze input must come from a SM-Applications or SM-Universal Encoder
Plus. The freeze data is processed every 4ms x number of dumb modules installed. If a freeze has occurred and the freeze flag (Pr x.39) is zero, the
position data is stored in Pr x.35 and Pr x.36 and the freeze flag is set. The freeze flag must be reset by the user before the next freeze event is
stored.

while the drive is powered-up.
If Pr x.49 is set to one, Pr x.04 and Pr x.05 are not updated. If this parameter is zero, Pr x.04 and Pr x.05 are updated normally.

not detected an error, a non-zero value indicates that an error has been detected. (See Table 5-15 on page 280 for the meaning of the values in this
parameter). When the drive is reset, this parameter is cleared.
The Solutions Module includes a temperature monitoring circuit. If the PCB temperature exceeds 90°C, the drive fan is forced to operate at full speed

SM-I/O Plus
Parameter update times
The SM-I/O Plus Solutions Module is a dumb Solutions Module and is controlled directly by the drive's main processor. The update time for some
functions are affected by the number of dumb Solutions Modules installed to the drive. The update time for these functions is the sum of the update
times for all dumb Solutions Modules installed to the drive, called the combined update time. This module contributes 8ms to the combined update
time. The update time for dumb Solutions Modules can vary, for example, the update time for SM-Encoder plus and SM-resolver modules is 4ms.
Therefore if an SM-Encoder plus and an SM-I/O plus module are installed to a drive, then the combined update time is 12ms. In this example all
parameters shown as having an update rate of "combined update time" would be updated every 12ms.
When a digital input or an analog input is the source for a parameter outside the Solutions Module menu the data from the input is written to the
destination parameter at the combined update time rate. When a digital output or the analog output is the destination for a parameter outside the
Solutions Module menu, the data is taken from the source parameter at the rate defined by the combined update time.

The menu for the relevant slot appears for the new Solutions Module category with the default parameter values for the new category.
When no Solutions Module is installed in the relevant slot this parameter is zero. When a Solutions Module is installed this parameter displays the
identification code.

The new parameter values are not stored in the drive EEPROM until the user performs a parameter save by setting Pr xx.00 to 1000 and pressing the
stop/reset button. When parameters are saved by the user in the drive EEPROM, the option code of the currently installed Solutions Module is saved
in the drive EEPROM. If the drive is subsequently powered-up with a different Solutions Module installed, or no Solutions Module is installed when
one was previously installed, the drive will trip on SLx.dF or SLx.nF.
This parameter shows the version of software programmed into the Solutions Module. The software sub version is displayed in Pr x.51.
These two parameters display the software version in the form of:
Pr x.02 = xx.yy
Pr x.51 = zz
If the Solutions Module analog input is programmed in any of the modes 2 to 5 (see Pr x.38 on page 302) then this bit is set if the current input falls
below 3mA. This bit can be designated to a digital output to indicate that the current input is less than 3mA.
0: OFF inactive
1: On active
Terminals T5 to T7 are three programmable digital inputs.
These parameters indicate the state of the digital input terminals.
If an external trip is required, then one of the terminals should be programmed to control the external trip parameter (Pr 10.32), with the invert set to a
On so that the terminal must be made active for the drive not to trip.
The digital inputs are set-up in positive logic only. This logic cannot be changed.

This word is used to determine the status of the digital I/O by reading one parameter.
Pr x.20 contains a binary value 'xx'. This binary value is determined by the state of Pr x.04 to Pr x.07. So for example, if all terminals were active the
value displayed in Pr x.20 would be the sum of the binary values shown in the table, i.e. 120.
Destination parameters define the parameter each of the programmable inputs is to control. Only parameters that are not protected can be controlled

Terminal T2 is a voltage/current reference input. The setting of this parameter configures the terminal to the required mode.
In modes 2 and 3, a current loop loss trip will be generated if the current input falls below 3mA, and Pr x.50 will be set to a 2.
If 4-20 or 20-4 modes are selected and the drive trips on current loop loss (cL), analog reference 2 cannot be selected if the current reference is
<3mA. If 4-.20 or 20-.4 modes are selected, Pr x.03 will switch from a OFF to On to indicate that the current reference is <3mA.
If bi-polar operation is required, the -10V reference must be generated and supplied by an external power supply.
Terminal T3 is a voltage/current output. The setting of this parameter configures the terminal for the required mode.
This parameter displays the level of the analog signal present at analog input 1.
In voltage mode, this is a bipolar voltage input where the input range is ±10V.
In current mode, this is a unipolar current input having a maximum measurable input of 20mA. The drive can be programmed to convert the measured
current to any one of the defined ranges in Pr x.38. The selected range is converted to 0.0 - 100.0%.
This parameter is used to scale the analog input if so desired. However in most cases it is not necessary as each input is automatically scaled such
that for 100.0%, the destination parameters (defined by the settings of Pr x.43) will be at maximum.

This parameter can be used to invert the analog input reference (i.e. multiply the input scaling result by -1).
Only parameters that are not protected can be controlled by analog inputs. If a non-valid parameter is programmed to the destination of an analog
input, the input is not routed anywhere. After a modification to this parameter, the destination is only changed when a reset is performed.
The parameter required to be represented as an analog signal by the analog output on Terminal T3 should be programmed in this parameter. Only
parameters that are not protected can be programmed as a source. If a non-valid parameter is programmed as a source, the output will remain at
zero. After a modification to this parameter, the source is only changed when a reset is performed.
This parameter can be used to scale the analog output if so desired. However in most cases it is not necessary as the output is automatically scaled
such that when the source parameter is at its maximum, the analog output will be at its maximum.
The error status is provided so that only one option error trip is required for each Solutions Module slot. If an error occurs, the reason for the error is
written to this parameter and the drive may produce an ‘SLX.Er’ trip (where X is the slot number). A value of zero indicates that the Solutions Module
this parameter for the SM-I/O Lite and SM-I/O Timer). When the drive is reset, this parameter is cleared.
(for a minimum of 20s). If the temperature falls below 65°C, the fan can operate normally again. If the PCB temperature exceeds 70°C, the drive will
trip on SLX.Er, and the error status is set to 74.
The Solutions Module includes a processor with software. The software version is displayed in Pr x.02 and Pr x.51 in the form Pr x.02 = xx.yy and Pr
x.51 = zz.

The performance of the freeze input is highly dependant upon the quality of the signal driving it. If negative edge triggering is used then care should
be taken to ensure that the input is actively pulled low via low impedance. If positive edge triggering is used then care should be taken to ensure that
the input is actively pulled high, or pulled high via a suitably low pull-up resistance.

204: SM-I/O PELV
The new parameter values are not stored in the drive EEPROM until the user performs a parameter save by setting Pr xx.00 to 1000 (or 1001 in the
case of solely using the 24V back-up power supply) and pressing the stop/reset button. When parameters are saved by the user in the drive
EEPROM, the option code of the currently installed Solutions Module is saved in the drive EEPROM. If the drive is subsequently powered-up with a
different Solutions Module installed, or no Solutions Module is installed when one was previously installed, the drive will trip on SLx.dF or SLx.nF.
This module contains two processors, and thus two software versions. Pr x.02 shows the version number of the main module processor. Pr x.51,
which is normally used to give a sub-version number, shows the software version in the slave processor, which operates on the PELV side of the
isolation barrier.
These parameters indicate the input and output states of the terminals.
The performance of the freeze input is highly dependant upon the quality of the signal driving it. If negative edge triggering is used then care should
be taken to ensure that the input is actively pulled low via low impedance. If positive edge triggering is used then care should be taken to ensure that
the input is actively pulled high, or pulled high via a suitably low pull-up resistance
The status of the PELV user power supply is shown in this parameter.

Setting these parameters to On(1) causes the input sense to the destination parameter to be inverted or the output sense from the source to be
inverted.
When digital input 5 is used to provide a freeze function, the invert Pr x.15 will select whether the freeze is applied on the rising (Pr x.15 = Off) or the
falling edge (Pr x.15 = On) of the input signal.
This parameter is only available on drive software V01.10.00 and later.
With Pr x.16 = OFF
The PELV user power supply absent trip is intended to detect when the PELV user supply connected to the module is below 19V. During power-up the
PELV user supply may not be present until after the main drive supply. To avoid unwanted trips in this situation, the PELV user power supply present
trip detection system is disabled until the supply has become active the first time. Therefore if the supply is applied and then removed a trip is initiated.
The trip is also initiated at any time after drive power-up if the supply is not present and the drive becomes active (i.e. Pr 10.02 is one). This condition
prevents the drive from operating if the PELV user supply is not present. The status of the PELV user supply can be monitored from parameter Pr x.06
(Off (0) =inactive, On (1) =active).
With Pr x.16 = On
The state of the PELV user power supply will never trip the drive. The drive can be enabled without the PELV user power supply present but all of the
module IO will be inoperable. Digital and analog inputs will read zero. Digital outputs will be in their inactive state and analog outputs will be at 0mA.
Setting these parameters to On (1) causes the output sense from the source to be inverted.
The freeze input function is enabled for DI5 if the destination parameter for this input (Pr x.25) is set to Pr x.19. Each time the input becomes active (or inactive
if the invert Pr x.15 is on) the freeze flag (Pr x.19) is set, the freeze system in the drive is triggered and held active.
Pr x.19 is updated within 500μs of the change on the freeze input, and the freeze event is registered with the drive after 500μs with a latency of 10μs.
The freeze flag is not automatically cleared when DI5 reverts to its original state. Another freeze event cannot be registered by the drive until all freeze
flags are cleared. If any other I/O destination is set to write to Pr x.19, the parameter value simply follows the data from the I/O and no freeze events
are produced. If this parameter is set by the user, it will not cause a freeze event even if it is the destination for DI5.
A minimum of 500μs must pass between consecutive freeze inputs. If a freeze input should occur less than 500μs after the previous one, the second
will be ignored and have no effect on the drive.

The parameter specified in these parameters by the user is the source parameter when corresponding digital I/O line is set as an output or destination
parameter when corresponding digital I/O line is set as an input. A total of 8 source or destination parameters can be defined. Pr x.21 to Pr x.28
corresponds to bits 0 to 7 (DIO1 to DIO8) respectively.
When the output select parameter for an I/O line is set to On, the I/O is set up as an output as follows:
The drive parameter defined by this parameter is the direction register for the fast update method. Setting the relevant bit to 1 within the direction
register parameter will select the corresponding I/O line to function as an output. If this parameter is set to 0.00 or a non existent parameter then all
I/O lines are defined as inputs for the fast update method. The direction register parameter range may not be large enough to allow all I/O lines to be
controlled. Any bits that cannot be controlled are assumed to be zero and the corresponding I/O lines are defined as inputs for the fast update
method.
The drive parameter defined by this parameter is the read register for the fast update method. When an I/O line is set up as an input for the fast
update method the corresponding bit in the read register shows the state of the input. Bits that correspond to I/O lines that are set as outputs in the
direction register or in the direction registers for the standard update method show the state of the output I/O line. If this parameter is set to 0.00 or a
non existent parameter then no read register is defined. The read register parameter range may not be large enough to allow the state of all I/O lines
to be shown; in this case the value containing the I/O status for all 32 I/O lines will be limited to the read register parameter range before being written
to the read register parameter.

The drive parameter defined by this parameter is the write register for the fast update method. Each bit in the write register will control the
corresponding I/O line provided it has been set up as an output in the direction register parameter. If this parameter is set to 0.00 or a non existent
parameter then all I/O lines set up as outputs are held in the non-active state. The write register parameter range may not be large enough to allow all
I/O lines to be controlled. The value written to the write register is subject to the normal range limiting.
Worked Example
By storing 20.21 in Pr x.43, Pr 20.21 will become the direction register for the digital I/O lines on the SM-IO 32 module. Storing 20.22 in Pr x.47 will
make Pr 20.22 the read register. Storing 20.23 in Pr x.48 will make Pr 20.23 the write register.
Storing a value of 29 (11101 in binary) in Pr 20.21 will make digital I/O lines 1, 3, 4 and 5 (which corresponds to bit 0, 2, 3 and 4) as digital output bits
and the remaining I/O lines will remain as digital input. Now these digital outputs can be written to using the write register Pr 20.23. Storing a value of
23 (10111 in binary) in Pr 20.23 will set digital I/O 1, 3 and 5 high (ON) and digital I/O 4 low (OFF). The write register will have no effect on digital I/O
2 when it tries to set it high (ON) because this digital I/O line has not been set as a digital output line by direction register. The read register, Pr 20.22
will show a value of 21 (binary 10101).
The control of the 32 digital I/O is limited by the range of the controlling parameter. Control of all the 32 digital I/O lines can only be achieved using
software like SyPTLite and SyPTPro. For example, with Pr 18.13 as the write register, 16 digital outputs can be written and with Pr 20.23 as the write
register, all the 32 digital outputs can be written
written to this parameter and the drive may produce an ‘SLX.Er’ trip (where X is the slot number). A value of zero indicates that the Solutions Module
this parameter). When the drive is reset, this parameter is cleared for the relevant Solutions Module.
This Solutions Module includes a temperature monitoring circuit. If the PCB temperature exceeds 85°C (185°F), the drive fan is forced to operate at
full speed (for a minimum of 10s). If the temperature falls below 75°C (167°F), the fan can operate normally again. If the PCB temperature exceeds
90°C (194°F), the drive will trip and the error status is set to 74.
The Solutions Module includes a processor with software. The software version is displayed in Pr x.02 and Pr x.51 in the form Pr x.02 = xx.yy and
Pr x.51 = zz, where:
zz specifies a change that does not affect the product documentation.

Product Variants
Different product variants within the SM-Applications range have different functionality and therefore some variants do not use all of the applications
module parameters. Modules that do not support all of the features have had hardware support for the unsupported features removed.
A comprehensive list of differences between the modules can be found in the relevant user guide for the SM-Applications module being used.
.
As some variants do not support all features of the SM-Applications range (for example SM-Applications Lite does not support CTNet) some error
codes and parameters are unused in these variants.
A mark next to the following parameters will indicate whether that parameter is available for a particular variant of the Applications module. The mark

Defines the baud-rate (or bits-per-second) for the on-board EIA-RS485 port. The following are supported:
Note that this parameter is not relevant when the EIA-RS485 port mode is set to 25 (CTSync Master) or 26 (CTSync Slave).
Defines a fixed delay between receiving a message on the EIA-RS485 port and the response being transmitted. This can be useful in 2-wire
configurations where it takes a finite time for the master (host) to switch from transmit mode to receive mode. There is always at least a 1ms delay
and this parameter can be used to extend it.
This parameter allows a 1ms delay to be introduced between the Applications module enabling the EIA-RS485 transmitter and actually commencing
the transmission. This should only be required if it is found that the recipient of the transmission is receiving a corrupted start of message.
This parameter is available on SM-Applications Lite module but is not allowed to be set to a 1 (On). Controls where the output of the DPL PRINT
command is sent. If set to zero (Off), the output is sent to the programming client (SyPTPro) and if set to 1 (On) it will be sent to the EIA-RS485 port.
Defines the scheduling period (tick-time), in milliseconds, for the DPL CLOCK task. A value of zero will disable the CLOCK task.
Prior to version 01.05.00 Unidrive SP the default for this parameter was 0ms (disabled).
Defines the scheduling rate for the POS tasks to suit the application performance and the resource needed to run the user DPL program. The
following values are defined::
Set this parameter in order for the user DPL program to automatically run at power-on/reset. If this is changed and the new setting needs to be used
on power-up ensure that a drive parameter save is performed.

With the Unidrive SP version 01.03.00 and earlier, the display will not show the actual rate, but its aliased number. For instance 250µs will be shown
on the display as 1.
Setting this parameter to 1 will cause the Unidrive SP to trip when certain run-time errors occur within the Applications module user DPL program.
For more information, see the Applications Modules User Guide.
When this parameter is 0, the module will be reset when a drive trip is cleared. When set to 1 the module will be unaffected by a drive trip reset (i.e.
continue running).
When this parameter is 0 the APC data and menu 90 encoder parameters are updated every 250µs.
When this parameter is 1 the APC data and menu 90 encoder parameters are updated immediately prior to every POS task.
When this parameter is 2 the APC data and menu 90 encoder parameters are updated immediately prior to every CLOCK task.
When 3 the APC data and menu 90 encoder parameters are never updated. If these are never updated, more processor resource will become free
.
Defines the action taken if a user DPL program attempts to write an out of range value to a parameter. When set at 1, a run-time trip will occur
(number 44); when set at zero the value will automatically be limited to the maximum/minimum of that parameter.
When set it enables the DPL program watchdog function. The DPL WDOG command must then be executed every 200ms. This can be used to
protect the program against malfunction. If the command is not executed within a 200ms time period the drive will trip on SLx.tO. Please note that the
WDOG command must also be executed once for the watchdog to be enabled. This is normally executed at the end of the Initial task.
Setting this parameter to 1 will initiate an immediate save of all non-volatile Applications module data. This consists of the P/Q/T/U PLC register sets
and optionally menu 20 (depending upon the setting of Pr x.21).
Note that this will also cause a reset of the module and this parameter will return back to zero automatically. Also if the Unidrive SP is tripped, it will be
reset. Menu 81 will not be saved.
Setting this parameter to 1 signals that all non-volatile data of the Applications module will be automatically saved upon an under voltage (UU) trip of
the drive.
Note that when a ‘UU’ save occurs the Applications module will be reset.

If set to 1, menu 20 will be saved/restored along with other non-volatile parameters upon a save request (Pr x.19=1) or power-down save (Pr x.20=1).
If menu 20 is to be restored on power-up the user must ensure that this parameter is saved in the drive before powering down.
Since menu 20 is a global drive menu, only one option installed to the Unidrive SP should be used to store and restore menu 20, therefore if more
than one Applications module is installed to the drive only one should have this parameter set otherwise menu 20 will not be restored correctly on
power-up.
Unlike other setup parameters, parameters Pr x.20 and Pr x.21 are not cached, which means a change to the parameter takes immediate effect.
This parameter allows the user to specify the identity of the CTNet token ring to which a Applications module is connected. In a system incorporating
a single token ring this parameter can be left at its default value. In a system incorporating multiple token rings, separate ID’s should be set for each
ring. The combination of CTNet Token Ring ID and CTNet node address should be unique.
Defines the node address for CTNet. Every node on a CTNet network must have a unique address. Setting this to zero will disable CTNet on this
node.
Specifies the data rate for CTNet. All nodes on the network must be set to the same data-rate. The rates are defined as follows:
Specifies the synchronization message generation rate for CTNet. This message is used to tell all nodes when to transmit cyclic data. Only one node
on the CTNet network should have this parameter set.
The format of the update parameter is SSFF, where FF defines the Fast Cyclic data channel update rate, and SS defines the slow cyclic data rate in
multiples of FF. So if the parameter value is 1510, fast cyclic data is set every 10ms and slow every 150ms. When using easy mode (see below) it is
only necessary to set up the FF (fast cyclic rate).

These parameters define the source and destinations for CTNet easy-mode cyclic data.
More information on CTNet easy mode data can be found in the CTNet User Guide.
Identifies which of the EVENT tasks will be scheduled when a CTNet synchronization message is received or generated. This sync. is generated by a
master node (which can be this node) on the CTNet network at a fixed time-base. The following values are defined:
The status of the CTNet network is displayed in the CTNet Diagnostic parameter. When the Applications module is communicating successfully on
the CTNet network the number of messages per second is displayed
If this parameter is set, then if the user attempts to download a new user DPL program or operating system to this module and the drive is enabled the
download will be rejected and a run-time trip 70 will occur, if the global run-time trip parameter (Pr x.14) is set.
Since downloading stops normal operations of the module it may be considered unsafe to do this if the drive system is running, therefore setting this
parameter will prevent downloading under this condition.
When this parameter is 0 the drive will trip with runtime error 81 if an APC non-recoverable error occurs, such as use of an initialized CAM function.
When this parameter is 1 the drive will not trip when an APC non-recoverable error occurs.

This parameter displays the current module’s synchronization status.
This is used to control the motion sequence user program.
When this parameter is ON (1), the voltage on the Applications module’s digital input 0 (zero) is passed through to the drive’s internal Freeze line.
This can be seen by other classes of SM-Solutions modules. For further information on the Freeze Input refer to the Applications Modules User
Guide.
♣♥When this parameter is set to zero a freeze occurs on the rising edge of the module’s DIGIN0. When it is set to 1 a freeze occurs on the falling
edge of the module’s DIGIN0. For further information on the Freeze Input refer to the Applications Modules User Guide.
♦
When this parameter is set to zero the module will freeze data when it sees a rising edge of a freeze pulse from the drive. When it is set to a 1 the
module will freeze data when it sees a falling edge of a freeze pulse from the drive. For further information on the Freeze Input refer to the
Applications Modules User Guide.

The system status parameter is used to indicate the status of each of the user program tasks and motion profiles. This parameter can give the user
some idea of what the SM-EZMotion module is commanding without being online using PowerTools Pro EZ.
There are six individual digits that indicate the status of different processes. This parameter will display a six digit number that can be used in
conjunction with the graphic below to determine the status of each process. Leading zeros in the value are not displayed.
Examples:
Pr x.48 = 11023 would signify that user programs are currently running on Task 2 and Task 1, and that a Index is running on Profile 1 while a Jog is
running on Profile 0.
Pr x.48 = 104 would signify that a user program is running on Task 0 and Gearing motion is running on Profile 0.

The error status is provided so that only one Solutions Module error trip is required for each Solutions Module slot. If an error occurs the reason for
the error is written to this parameter and the drive may produce a SLx.Er trip, where x is the slot number. A value of zero indicates that the module has
parameter). When the drive is reset this parameter is cleared for all Solutions Modules.
All modules include a temperature monitoring circuit. If the PCB temperature exceeds 90°C the drive fan is forced to operate at full speed (for a
minimum of 10s). If the temperature falls below 90°C the fan can operate normally again. If the PCB temperature exceeds 100°C the drive is tripped
and the error status is set to 74.
Most Solutions Modules include a processor with software. The software version is displayed in these parameters in the form Pr x.02 = xx.yy and
Pr x.50 = zz. Where xx specifies a change that affects hardware compatibility, yy specifies a change that affects product documentation, and zz
specifies a change that does not affect the product documentation. When a module is installed that does not contain software both these parameters
appear as zero.

501: SM-SLM
The new parameters values are not stored in the drive EEPROM until the user performs a parameter save. When parameters are saved by the user
in the drive EEPROM the option code of the currently installed Solutions Module is saved in the drive EEPROM. If the drive is subsequently powered-
up with a different Solutions Module installed, or no Solutions Module installed where one was previously installed, the drive gives a SLx.dF or SLx.nf
trip.
Provided the set-up parameters for the position feedback are correct this parameter shows the speed feedback in rpm. This parameter is filtered to
increase readability.
These parameters effectively give the position with a resolution of 1/232
counter.
The marker offset corrects this position.

SM-SLM
This parameter defines the mode of operation of the drive:
0 - HoSt: Host mode (Torque amplifier only)
1 - Enc.Only: Encoder only mode
Host mode uses an external position controller host and an SM-SLM for the speed loop. The host controller will handle all SLM calculations for
initialisation. The UniSP acts as torque amplifier similar in operation as the MultiAx drive.
Enc.Only mode uses the SLM module for speed feedback and nameplate data only.
The encoder has a marker channel and this is used to correct the absolute position within a revolution after power-up. After passing through the
marker this bit is set and the zero offset parameter is updated with the difference between zero of the encoder position and the marker. This error is
due to the initial angle calculation using the single cycle SinCos. The power-up single cycle SinCos method has a maximum error of ±3°.
This parameter converts the drive phase angle (Pr 3.25) into an SLM EEPROM (CT Coder) nameplate flux offset value. The drive is the electrical
angle offset in degrees. The SLM flux offset is the mechanical offset in 65535 places per revolution offset by 120°.
This parameter is used to set the mask used on the fine position sent from the SLM module to the Solutions Module. 1024 lines results in 6 extra bits
of fine position information being used. This takes the full position resolution to 22 bits. A 2046 line encoder uses 7 extra bits of fine position etc.
Indicates the software version of the SLM module installed to the motor. This is SLM Pr 100 which needs to have been transferred if in HOST mode.
The format is p.vvv where p is the page and vvv is the software version of the page.
This parameter specifies the time delay between the drive power-up and the SLM being available in 250ms units.

The EEPROM CRC check performed by the host is listened to by the SM-SLM which stores parameters ready to transfer to the drive. When Pr x.28
is written to by the host, the appropriate stored EEPROM data is written to the drive parameters. If the host does not wish to use this function, nothing

When loading using Pr x.26 = 1, the parameter set loaded on power-up or restart depends on Pr x.28.
The parameter set is the same as was controlled by Pr x.27 when saving was performed.
In Encoder only mode, a parameter transfer cannot be performed with the drive in either RUN or STOP.

5.21 Menu 21: Second motor parameters
The following parameters are used instead of the normal motor set-up parameters when Pr 11.45 = 1.
When the alternative parameter set is being used by the drive the decimal point after the right hand digit in the 1st row is on.
For more information about a particular parameter, see the equivalent normal motor map 1 parameter.
* The range shown for Pr 1.07 shows the range used for scaling purposes (i.e. for routing to an analog output etc). Further range restrictions are
applied as given below.
Unlike the motor 1 (Pr 1.14) this parameter is not used for T28 and T29 digital input auto-selection (see Pr 8.39 on page 169).

Menu 22 contains parameters that are used to set up the source parameters for menu 0 in addition to those that are set up from within Menu 11.
These parameters define the parameters that reside in the programmable area in menu 0.
Table 5-40 Menu 22 default settings
It should be noted that if the parameter values saved in the drive EEPROM or on a SMARTCARD are all zero for menu 22 the drive will automatically
load defaults for this menu when the drive is powered up or the parameters are transferred from the SMARTCARD. This ensures that defaults are
used for this menu if the saved parameters are from a software version which did not include this menu.

6 Macros
6.1 Introduction
A macro is a simple and easy way of setting up the parameter routing in
a drive for a specific application. It brings specific parameters into the
programmable section of menu 0 for easy access and sets up internal
software routing to give the user I/O terminals the functions required for
the application.
Unidrive classic had several predefined macros available for the
following types of set up.
Table 6-1 Macros that are available
* Only available in closed loop vector or servo operating modes.
Macro 1 – Easy Mode
The Easy mode macro gives the simplest operation of the drive for basic
applications. It is identical to the default condition except that menu 0
has less parameters.
Macro 2 – Motorized potentiometer
The Motorized potentiometer macro enables the drive's own internal
motorized potentiometer to control the speed of the drive via digital
inputs. A digital input selects between an analog speed reference and
the motorized potentiometer reference.
Macro 3 – Preset frequencies / speeds
The Preset reference macro enables the use of preset references to
control the speed of the motor via digital inputs. A digital input selects
between an analog speed reference and the preset references.
Macro 4 – Torque control
The Torque control macro configures the drive for use in Torque control
mode, selectable via a digital input. Analog input 1 is configured for the
torque reference. When in speed control analog 2 is the speed
reference. When in torque control with the drive in closed loop mode
analog input 2 is the speed override reference. Enabling torque mode
with the drive in open loop mode will put the drive in to pure torque
control. In closed loop mode the drive will be put in to torque control with
speed override.
Macro 5 – PID (set-point control)
The PID control macro enables the drive's own internal PID controller to
control the speed of the motor. Analog input 1 is configured for the main
speed reference, analog input 2 is the PID reference and analog input 3
is the PID feedback. A digital input selects between an analog speed
reference and the PID control.
Macro 6 – Axis-limit control
The Axis limit control macro configures the drive for use with limit
switches so that the drive is stopped when a position limit has been
reached. The speed reference can be either unipolar or bipolar.
Macro 7 – Brake control
The brake control macro configures the drive to apply or release a
mechanical brake on a motor in a crane or hoist application. The drive
issues a brake release signal via a digital output when the relevant
conditions are met.
Macro 8 – Digital lock / shaft orientation
Only available in closed loop vector or servo operating modes.
Digital lock:
The drive operates as a slave in a closed loop master-slave system.
The slave motor is digitally locked to the master motor.
Shaft orientation:
The motor speed is controlled in the same way as for default operation,
but the motor shaft can be orientated to a specified angular position
before and/or after running the motor.
This section details how to replicate the Unidrive classic macros in a
Unidrive SP.
The programmable section of Menu 0 is from Pr 0.11 - Pr 0.30 inclusive.
The other menu 0 parameters have fixed functions used in every mode

6.1.1 Fundamental differences between Unidrive SP
and Unidrive Classic
The following Macros simulate the equivalent Macros in Unidrive classic.
The following are exceptions in functionality between the Macros in
Unidrive Classic and Unidrive SP:
• The Unidrive SP Macros run in positive logic, unlike Unidrive Classic
Macros which run in negative logic.
• You do not have access to change Analog Input 1 mode in any
Unidrive SP macro, as analog input 1 is now a dedicated high
precision voltage input, and cannot be turned into a current loop
input.
• The SECURE DISABLE input on Unidrive SP, which is an enhanced
equivalent of the enable input on Unidrive Classic, is now on
terminal 31, unlike Unidrive Classic which uses terminal 30. The
SECURE DISABLE input is also permanently positive logic, unlike
the enable input in Unidrive Classic, which can be changed to
negative logic.
• Macro 3 on Unidrive SP works in a slightly different way to Unidrive
Classic. In the Unidrive Classic Macro 3, the only way in which the
preset speeds can be enabled was to switch digital input F6 to logic
1. In Unidrive SP the software structure has changed, to be in line
with Commander SE. This means that if you switch on either, or both
of the preset selects, then regardless of the state of the preset
enable, the drive will automatically enable the preset speeds as the
speed reference.
• The brake is now an additional feature in Menu 12, with enhanced
features over the Unidrive Classic. It is recommended that the brake
controller in Menu 12 is used instead of Macro 7 - Brake Control.

6.5 Macro 4 - Torque control
Macro 4 Torque control
The Torque control macro configures the drive for use in Torque control mode, selectable via a digital input. Analog input 1 is configured for the
torque reference. When in speed control analog 2 is the speed reference. When in torque control with the drive in closed loop mode analog input 2
is the speed override reference. Enabling torque mode with the drive in open loop mode will put the drive in to pure torque control. In closed loop
mode the drive will be put in to torque control with speed override.

6.8 Macro 7 - Brake control
It is recommended that the brake control in menu 12 is used instead of Macro 7 - Brake control.
Where a safety hazard may exist the drive alone must not be permitted to release the brake. An independent safety interlock must be
provided to ensure safe operation in the event of drive failure or incorrect operation.
WARNING
Macro 7 Brake control
The brake control macro configures the drive to apply or release a mechanical brake on a motor in a crane or hoist application. The drive issues a
brake release signal via a digital output when the relevant conditions are met.

6.9 Macro 8 - Digital Lock
Macro 8 Motorized potentiometer
Only available in closed loop vector or servo operating modes. This macro requires that a feedback solutions module (SM-Universal Encoder Plus,
SM-Encoder Plus or SM-Resolver) is installed in slot 3 of the drive. This macro uses the feedback solutions module in slot 3 as the position
reference and the drives encoder port as the position feedback source.
Digital lock: The drive operates as a slave in a closed loop master-slave system. The slave motor is digitally locked to the master motor.
Shaft orientation: The motor speed is controlled in the same way as for default operation, but the motor shaft can be orientated to a specified
angular position before and/or after running the motor.

7 Serial communications
protocol
7.1 ANSI communications protocol
7.1.1 Introduction
Unidrive SP supports an ANSIx3.28 type comms protocol as supported
by previous Control Techniques products with some modification to allow
access to 32 bit parameters. This chapter describes the implementation
of the protocol for Unidrive SP.
7.1.2 Physical layer and UART
7.1.3 Reading a parameter
The command to read a parameter is:
If the message is correct and the parameter exists the response is:
The length of the data field varies depending on the number of
significant digits required to represent the value of the parameter. The
maximum length is 12 digits including the sign and decimal point if
present. The data field always starts with a sign, minus sign for negative
numbers, or a plus sign for zero and positive numbers. The field may
contain a decimal point, but this will not be before all the numbers in the
field or after all the numbers in the field. The following examples
demonstrate some possible data fields.
If the parameter to be read does not exist the End of transmission
character (Ctl D) is returned.
The checksum is derived by exclusive ORing the message byte together
excluding the STX and the checksum, i.e. Checksum = M1 ^ M2 ^ P1^
P2 ^ D1 ^ D2 ^ ...... Dn ^ ETX. The checksum is an unsigned 8 bit value
and if the checksum is less than 32 then 32 is added to the calculated
checksum.
7.1.4 Writing to a parameter
The command to write to a parameter is:
The following rules apply to the data field:
1. The maximum length is 12 characters.
2. The field may contain leading spaces, but not after any other
character.
3. A sign character is optional. No sign indicates positive.
4. A decimal point is optional. This can appear at any point in the data
field, but not before the sign or before 10 numbers (i.e. the value
written should not have more than 9 decimal places). If the decimal
point is not in the same position as used by the parameter some
accuracy may be lost or extra decimal places added (i.e. if +1.2345
is written to a parameter with one decimal place the result is +1.2, if
+1.2 is written to a parameter with three decimal places the result is
+1.200). It should be noted that parameters can only have 0, 1, 2, 3,
4, 5, or 6 decimal places.
5. The data field can contain up to 10 numbers, but the value even
ignoring decimal points must not exceed the range –231 to 231-1.
If the parameter is written successfully an Acknowledge character (Ctl F)
is returned. If the parameter does not exist, the value written exceeds
the allowed parameter range or the data field rules are not obeyed an
Not acknowledge character (Ctl U) is returned.
The checksum is derived by exclusive ORing the message byte together
excluding the STX and the checksum, i.e. Checksum = M1 ^ M2 ^ P1^
P2 ^ D1 ^ D2 ^ ...... Dn ^ ETX. The checksum is an unsigned 8 bit value
and if the checksum is less than 32 then 32 is added to the calculated
checksum.

7.1.5 Drive address
The drive only acts on messages received that contain a drive address if
the whole drive address or drive group address match the whole
address or the group address in the message, or if the address in the
message is 0 (i.e. a global message). Global or group addressing allows
data to be written to more than one drive with one command. The drive
does not give a response to a global or group write message. Although it
is possible to perform a global or group read, this would result in
messages crashing if more than one drive responds to the command.
7.1.6 Short commands
The following short commands can be used:
This is the same as requesting the value of the last parameter to be read
or written to. The response is the same as for a normal read.
This is the same as requesting the value of the parameter after the last
parameter to be read or written to. The response is the same as for a
normal read.
This is the same as requesting the value of the parameter before the last
parameter to be read or written to. The response is the same as for a
normal read.
Writes to the specified parameter at the same drive address as used by
the last read or write.
All the short commands will only read from the drive or write to the drive
if a valid address has already been sent to the drive in a previous
command. The address is registered as being valid once a read or write
command has been completed provide the address was valid for the
drive even if the parameter does not exist. The valid address is
cancelled if a message is received for a non-valid address or one of the
following occurs:
1. The command is aborted because a non-numerical value is received
in the drive address, menu or parameter numbers.
2. The command is aborted because the two digits for drive address 1st
digit, drive address 2nd
digit, menu number or parameter number are
not the same as each other.
3. EOT is received.
4. A character other than NAK, ACK, BS or STX is sent as a short
command.
5. A character other than ENQ is sent at the end of a read command.
7.1.7 Summary of control characters
7.2 CT Modbus RTU specification
This section describes the adaptation of the MODBUS RTU protocol
offered on Control Techniques' products. The portable software class
which implements this protocol is also defined.
MODBUS RTU is a master slave system with half-duplex message
exchange. The Control Techniques (CT) implementation supports the
core function codes to read and write registers. A scheme to map
between MODBUS registers and CT parameters is defined. The CT
implementation also defines a 32bit extension to the standard 16bit
register data format.

7.2.1 MODBUS RTU
Physical layer
* The drive will accept a packet with 1 or 2 stop bits but will always transmit 2 stop bits
RTU framing
The frame has the following basic format
The frame is terminated with a minimum silent period of 3.5 character
times (for example, at 19200 baud the minimum silent period is 2ms).
Nodes use the terminating silence period to detect the end of frame and
begin frame processing. All frames must therefore be transmitted as a
continuous stream without any gaps greater or equal to the silence
period. If an erroneous gap is inserted then receiving nodes may start
frame processing early in which case the CRC will fail and the frame will
be discarded.
MODBUS RTU is a master slave system. All master requests, except
broadcast requests, will lead to a response from an individual slave. The
slave will respond (i.e. start transmitting the response) within the quoted
maximum slave response time (this time is quoted in the data sheet for
all Control Techniques products). The minimum slave response time is
also quoted but will never be less that the minimum silent period defined
by 3.5 character times.
If the master request was a broadcast request then the master may
transmit a new request once the maximum slave response time has
expired.
The master must implement a message time out to handle transmission
errors. This time out period must be set to the maximum slave response
time + transmission time for the response.
7.2.2 Slave address
The first byte of the frame is the slave node address. Valid slave node
addresses are 1 through 247 decimal. In the master request this byte
indicates the target slave node; in the slave response this byte indicates
the address of the slave sending the response.
Global addressing
Address zero addresses all slave nodes on the network. Slave nodes
suppress the response messages for broadcast requests.
7.2.3 MODBUS registers
The MODBUS register address range is 16bit (65536 registers) which at
the protocol level is represented by i
