For data transfer between CNC CPUs and PLC CPUs, we have newly developed a dedicated high-speed bus. Data are transferred at a high-
speed cycle (0.88ms) between the high-speed shared memories of each CPU, so each CPU speed can be fully utilized.
When commanding positioning (G00) and linear interpolation (G01),
the in-position widths can be respectively specified in a machining
program. This enables designation of the optimal in-position width for
each machining pattern, thereby allowing tact time to be reduced.
A wide variety of Mitsubishi PLC MELSEC Q Series' network modules can be used.

The in-position width for positioning (G00) can be set independently
of the width for linear interpolation (G01).
For example, you can shorten the positioning time while maintaining
the depth accuracy by setting the G01's width smaller and G00's
width larger.

Basic performance has been significantly enhanced by combining
the highly responsive current control (High-gain control) and a
high-accuracy servo motor.
In addition to the high-responsive current control, lost motion
compensation and an adaptive-type resonance suppression filter,
etc. are installed. These can realize reduced machining time,
elimination of machine vibration and enhanced machining accuracy.
The connection with the detector is high-speed and highly reliable
serial communication.
The servo axis detects and compensates the spindle's delay directly on
the high-speed optical network to minimize the synchronization error.
Orientation time is reduced
Under MDS-D2/DH2 Series spindle control, position loop control is
constantly maintained. Thus, controlling with the maximum torque is
always possible with no need for position control switching. As
deceleration can be performed with the maximum torque, the
spindle's orientation time has been reduced by 20%.
Heavy cutting performance improved
Heavy cutting performance has been improved due to the position
loop of the spindle control. By lowering impact load fluctuation, the
speed fluctuation rate has been reduced to less than 1/2 of our
conventional system.

This function corrects the actual tool center path inward or outward from
the programmed path by the tool's radius amount.
Tool radius compensation
This function assumes the tool nose to be a half circle of radius R,
and performs compensation so that the half circle touches the
programmed path. This can correct the error caused by the tool nose
roundness.
It is possible to select whether the compensation direction is fixed, or
automatically determined from the tool tip and the specified
movement vector.

Fans inside C70 control module have been removed, as cooling is executed by radiator
fin. Thus, fan-related troubles (electric circuit failures that are caused by fan stop,
inspiring moisture into the panel) can be avoided.
Through a GOT screen operators can backup and restore data to an
SD card, USB memory or CF card inserted into the GOT (Note).
Which data needs to be backed up is automatically determined.
(Note) Available devices vary according to your GOT type.
Quick restoration with module replacement and restoration function in case of troubles
By using a connector on motor's power line, wiring workability has
improved.
Allows for easier wiring
The main base, power supply and extension base are the same as
those used for MELSEC, thus MELSEC Q Series' versatile I/Os and
instrumentation modules are available.
Possible to cut maintenance cost by using the same parts as
MELSEC.
Maintenance parts are the same as for MELSEC,
thus possible to use the same parts.
The absence of fan inside the drive unit can contribute to the avoidance of electric
circuit failures that are caused by inspiring dust, oil-mist, etc. The oil resistance of
radiator fin cooling fans, which are located outside the panel, has been improved by
molding the stator coil (IP65).
With this function, the CNC operation and time information is always
stored, which is used for trouble diagnosis, etc. Operation history
data include the CNC alarms, key inputs and CNC input/output signal
changes, which are stored together with the occurrence times.
These history data are backed up even during power shut-down.
Helps trouble diagnosis with time display
Under this control, a built-in thermistor detects the spindle motor's
temperature to compensate the motor constant fluctuation due to rise of
temperature. It is also possible to monitor spindle motor's temperature
on CNC screen.
Suppresses the output characteristic deterioration when the temperature is low
Monitors cooling fan's rotation, and detects "Fan stop warning" that is
output when the fan stops rotating. Previously, the motor was
stopped in the event of fan stop by the module overheat alarm. With
this "Fan stop warning"; however, the fan can be replaced
systematically without stopping the motor.
Allows systematic fan replacement
Ground fault detection, which was formerly performed all at a time by
a power supply unit, has changed so that the fault can be detected
per motor. As detecting a faulty axis is possible, restore time will be
shorter.

Large-capacity CPUs have been added to C70's PLC CPU lines.
Program capacity as well as standard ROM capacity have also been
extended.
The number of sequence programs has been extended up to 124 to
enable the precise management of programs according to product or
process, etc. By subdividing and structuring sequence programs, the
visibility and availability of programs are enhanced.
GOT Screen Design Software (GT Works3) enables simple custom
screen development. Possible to operate machine with the touch
panel screen, instead of the conventional machine operation panel.
PLC ladder program can be edited without GX Works, when "Sequence
program monitor" of GOT2000 or "Ladder edit" of GOT1000 is applied.
With this function, you can also check the operating status of a sequence
program.
CNC monitor has been installed, which allows editing of machining
programs and setting each CNC data.
The CNC monitor can be used simply by installing from GT Works3
thus no need to develop screen. The CNC monitor screen can be
displayed by connecting to the CNC CPU's DISPLAY interface via
Ethernet or by connecting to the main base via bus.
CNC monitor supports only models with display resolution SVGA or
more.

An independent PLC CPU allows suitable selection of the right module for your system's size and purpose, realizing an optimal hardware
configuration.
PLC CPU and each I/O unit, and intelligent units are connected via Q bus; thus, conventionally used power supply, I/O and network modules for
MELSEC Q Series can be used.
Enables configuring the system optimal for your system
Possible to define up to 1200 sets of variables, which are able to
write/read from a PLC CPU. These variable sets can be handled as
system variables in the machining program.
Write/Read is performed using special instructions.
This function is useful when a large number of variable sets are
needed, such as for a grinder.

Even if a pallet is changed, the axis can always be controlled as an
NC axis in the machining area, and as a PLC axis in the setup area,
which enables setup of a rotary axis without stopping machining.
NC axis/PLC axis changeover
An independent axis control by PLC is possible, apart from NC
control axes. PLC axis control is useful for controlling the axis not
involved in machining such as tool magazine and pallet changer.

Environmental protection
This control system is compliant with the harmonized standards of European Machinery Directive: EN ISO 13849-1:2008 Category 3 PL d and EN62061/SILCL2.
In addition to the safety signal monitoring function that monitors redundant signal input/output, this system is equipped with Safely limited speed
(SLS), a function to monitor a moving part speed, and shutoﬀ functions. The operating conditions of these safety functions can freely be
programmed in CNC CPU and PLC CPU ladder circuits, thereby allowing you to build a safety system compatible with Safe operating stop (SOS), Safe
torque OFF (STO) and Safe brake control (SBC).
Other safety related functions
European Safety Standards CE Marking (machine directive) prohibits machine protection door from being opened during axis traveling. Door
interlock function decelerates and stops all the control axes when door open signal is input from PLC, and then performs Ready OFF to shut
down the driving power inside the servo drive unit to disable the motor driving.
Door interlock
Application of the power regeneration system which allows energy
generated during deceleration to be efficiently used as a power supply.
Use of low-loss power devices enables reductions in loss of power.
Energy loss of spindle motors during high-speed operation has been
substantially reduced. Drive current of servo motors has also been
reduced by downsizing the motors while increasing the torque.

C70, which is open equipment, must be installed within a sealed metal control panel (IP54 or higher). C70 must also be used and stored under the conditions listed in the specifications table above.
The following environmental conditions are also required for the layout design.
• No large amount of conductive dust, iron filings, oil mist, salt, or organic solvents
• No direct sunlight
• No strong electrical or magnetic fields
• No direct vibrations or shocks to the C70
(Note 1) This indicate at which point this equipment is assumed to be connected between a public power distribution network and local machinery equipment.
Category II applies to equipment for which electrical power is supplied from fixed facilities. The surge voltage withstand level for the rated voltage of up to 300V is 2500V.
(Note 2) This index indicates the degree to which conductive material is generated in terms of the environment where the equipment is used.
Pollution level 2 means that only non-conductive pollution can occur. However, a temporary conductivity may be caused by accidental condensing.
(Note 3) Do not use or store the C70 under pressure higher than the atmospheric pressure of altitude 0m. Doing so may cause an operation failure.

*1: The power-on time ratio indicates the ratio of C70 power-on time to one day (24 hours).
(When the total power-on time is 12 hours and the total power-off time is 12 hours, the
power-on time ratio is 50%.)
*2: The guaranteed value is equivalent to the total power failure time which we have calculated
based on the memory's (SRAM) characteristic value provided by the manufacturer under the
storage ambient temperature range of -25 to 75°C (operating ambient temperature of 0 to 55°C).
*3: The actual service value; equivalent to the total power failure time that is calculated based
on the measured value under storage at ambient temperature of 40°C. This value is
intended for reference only, as it varies with the characteristics of the memory, etc.
Replace batteries every five years.
*4: In the following status, the back-up time after power OFF is 3 minutes.
• The battery connector is disconnected. • The battery lead wire is broken.

The number of axes that is within the max. number of control axes, and that does
not exceed the max. number given for the NC axis, spindle and PLC axis, can be
used.
Up to three part systems for the lathe system, and up to seven part systems for the
machining center system.
When axis coordinate data is issued in a machining program command, either the
incremental command method that commands a relative distance from the current
position or the absolute command method that moves to a designated position in a
predetermined coordinate system can be selected.
For decimal point input type I, the minimum digit of a command not using a decimal
point is the same as the least command increment. For decimal point input type II,
when there is no decimal point, the final digit serves as the millimeter unit in the
metric mode, as the inch unit in the inch mode and as the second unit in the time
designation.
This function carries out high-speed transmission of machining programs to the
large capacity buffer memory in the CNC CPU using the FTP function of Ethernet to
run the programs. The operation thus requires an Ethernet connection with an FTP
server such as personal computer or a GOT with FTP server function to which a CF
card is connected.
For the axis command value, the radius designation or diameter designation can be
changed over with parameters. When the diameter designation is selected, the
scale of the length of the selected axis is doubled. (Only half (1/2) of the command
amount moves.)
This function carries out positioning at high speed using a rapid traverse rate with
the travel command value given in the program.
The G code command always moves the tool to the final position in the direction
determined by parameters.
Linear interpolation is a function that moves a tool linearly by the travel command
value supplied in the program at the cutting feedrate designated by the F code.
The unit systems of the data handled in the controller include the metric system and
inch system. The type can be designated with the parameters and machining
program.
This function moves a tool along a circular arc on the plane selected by the travel
command value supplied in the program.
With this function, any two of three axes intersecting orthogonally are made to
perform circular interpolation while the third axis performs linear interpolation in
synchronization with the arc rotation. This control can be exercised to machine
large-diameter screws or 3-dimensional cams.
This function transfers the shape that is on the cylinder's side surface (shape yielded by
the cylindrical coordinate system) onto a plane, and when the transferred shape is
designated in the program in the form of plane coordinates, the shape is converted into
a movement along the linear and rotary axes of the original cylinder coordinates, and
the contours are controlled by means of the CNC unit during machining.
This function converts the commands programmed by the orthogonal coordinate
axes into linear axis movements (tool movements) and rotary axis movements
(workpiece rotation) to control the contours. It is useful for cutting linear cutouts on
the outside diameter of the workpiece, grinding cam shafts, etc.

The rapid traverse rate can be set independently for each axis using the parameters.
This function specifies the feedrate of the cutting commands, and gives a command
for a feed amount per spindle rotation or feed amount per minute.
The manual feedrates are designated as the feedrate in jog mode or incremental
feed mode for manual operation and the feedrate during dry run ON for automatic
operation. The manual feedrates are set using external signals.
This function multiplies the rotary axis' command speed by ten during initial inching.
By issuing a G command, the commands from the block are issued directly by the
numerical value following F as the feedrate per minute (mm/min, inch/min).
By issuing a G command, the commands from the block are issued directly by the
numerical value following F as the feedrate per spindle revolution (mm/rev,
inch/rev).
The feedrate registered by parameter in advance can be assigned by designating a
single digit following address F.
Override can be applied to manual or automatic rapid traverse using the external
input signal supplied.
Override can be applied to the feedrate command designated in the machining
program using the external input signal supplied.
Override can be further applied as a second-stage override to the feedrate after the
cutting feed override has been applied.
By turning ON the external override cancel signal, the override is automatically set
to 100% for the cutting feed during automatic operation mode (memory and MDI).
Acceleration/deceleration is applied to all commands automatically. The
acceleration/deceleration patterns are linear acceleration/deceleration, soft
acceleration/deceleration, exponent function acceleration/deceleration, exponent
function acceleration/linear deceleration and any other that can be selected using a
parameter.
This function performs acceleration/deceleration at a constant inclination during
linear acceleration/deceleration in rapid traverse mode. Compared to the method of
acceleration/deceleration after interpolation, the constant inclination
acceleration/deceleration method improves cycle time.
Thread cutting with a designated lead can be performed. Inch threads are cut by
designating the number of threads per inch with the E address.
By commanding the lead increment/decrement amount per thread rotation, variable
lead thread cutting can be performed.
This function performs tapping through synchronized control of the spindle and
servo axis. This eliminates the need for floating taps and enables tapping to be
conducted at a highly accurate tap depth.
The load applied to the tool can be reduced by designating the depth of cut per
pass and cutting the workpiece to the hole bottom for a multiple number of passes.
Chamfering can be enabled during the thread cutting cycle by using external
signals.
This function enables two or more spindles to perform synchronous tapping at a
time, thereby improving the tapping efficiency.
This function increases the accuracy and shortens the cycle time of synchronous
tapping by making the NC axis follow the spindle using drive unit communication.
The tool can be moved at the rapid traverse rate for each axis separately. Override
can also be applied to the rapid traverse rate by means of the rapid traverse
override function.
The tool can be moved in the axis direction (+ or –) in which the machine is to be
moved at the per-minute feedrate.
The tool can be operated by an amount equivalent to the designated amount
(incremental value) in the axis direction each time the jog switch is pressed.
The machine can be moved in very small amounts by rotating the manual pulse
generator.
The G code command temporarily stops machine movement and sets the machine
stand-by status for the time designated in the program.
Machining programs are stored in the CNC memory.

M system L system
Spindle
functions (S)
Tool
functions (T)
The spindle rotation speed is determined in consideration of the override and gear
ratio for the S command given in automatic operation or with manual numerical
commands, and the spindle is rotated.
This interface is used to connect the digital spindle (AC spindle motor and spindle
drive unit).
Spindle control can be executed using an analog spindle instead of the digital
spindle.
Constant output characteristics can be achieved across a broad spectrums down to
the low-speed ranges by switching the spindle motor connections. This is a system
under which commands are assigned from the PLC.
Constant output characteristics can be achieved across a broad spectrums down to
the low-speed ranges by switching the spindle motor connections. This is a system
under which the CNC module switches the coils automatically in accordance with
the motor speed.
When an eight-digit number is commanded following the address S (S-99999999 to
S99999999), 32-bit binary data with a sign and the star signal will be output to the PLC.
With radial direction cutting, this function enables the spindle speed to be changed
in accordance with changes in the radial direction coordinate values and the
workpiece to be cut with the cutting point always kept at a constant speed (constant
surface speed).
This function applies override to the rotation speed of a spindle assigned by the
machining program command during automatic operation or by manual operation.
When using a machine tool equipped with several spindles, this function controls
those spindles.
This function enables one spindle drive unit to also be used as the C axis (rotary
axis) using an external signal.
The C axis servo ON signal is used to switch between the spindle and C axis.
This function stops the spindle rotation at a certain position.
In a machine with two or more spindles, this function controls the rotation speed
and phase of one selected spindle (synchronized spindle) in synchronization with
the rotation of the other selected spindle (basic spindle). There are two methods for
giving commands: G code and PLC.
The spindle rotation speed is clamped between max. rotation speed and min.
rotation speed.
The command is issued with an 8-digit number following address T (T0 to
T99999999). The tool function is used to command the tool No. In the lathe
specification controller, the tool compensation (tool length compensation, tool nose
wear compensation) Nos. are also indicated.
When an 8-digit number (M00000000 to M99999999) is assigned following address
M, the 8-digit code data and start signal are output to the PLC.
Four sets of M commands can be issued simultaneously in a block.
When the M00, M01, M02 or M30 command is assigned during an automatic
operation (memory, MDI) or by a manual numerical command, the signal of this
function is output. It is turned OFF after the miscellaneous function finishes or by
the "Reset & Rewind" signal.
These signals inform the CNC system that a miscellaneous function (M), spindle
function (S), tool function (T) or 2nd miscellaneous function (A, B, C) has been
assigned, and that the PLC which has received it has completed the required
operation. They include miscellaneous function finish signal 1 (FIN1) and
miscellaneous function finish signal 2 (FIN2).
The code data and start signals are output when an 8-digit number is assigned
following the address code A, B or C — whichever does not duplicate the axis
name being used.
These commands make it possible to control the axis movement by offsetting the
position of the end point of the travel command by the amount set on the TOOL
OFFSET screen.
These commands function to provide tool radius compensation. Through a
combination with the G command and D address assignment, they compensate the
actual tool center path either inside or outside the programmed path by an amount
equivalent to the tool radius.
Corresponding to the tool No., the tool nose is assumed to be a half circle of radius
R, and compensation is made so that the half circle touches the programmed path.
The nose radius compensation direction is automatically determined from the tool
tip and the specified movement vector.
The standard for the machining center system is 40 sets.
Note that the standard for the machining center system with 3-part systems will be
up to 80 sets/part system, or with 4-part systems or more, up to 40 sets/part system.
For the lathe system, up to 80 sets/part system regardless of the number of part
systems.

Return
The machine coordinate system is used to express the prescribed positions (such
as the tool change position and stroke end position) characteristic to the machine,
and it is automatically set immediately upon completion of the first dog-type
reference position return after the power has been turned ON or immediately after
the power has been turned ON if the absolute position specifications apply.
By issuing a G code, the program coordinate system (zero point of program) can be
changed on the workpiece coordinate system.
After turning the power ON, even without executing the reference position return,
the basic machine coordinate system and the workpiece coordinate system are set
automatically.
When multiple workpieces with the same shape are to be machined, these
commands enable the same shape to be machined by executing a single
machining program in the coordinate system of each workpiece.
An external workpiece coordinate offset that serves as a reference for all the
workpiece coordinate systems is available outside the workpiece coordinates. By
setting the external workpiece coordinate offset, the external workpiece coordinate
system can be shifted, and all the workpiece coordinate systems can be
simultaneously shifted by an amount equivalent to the offset.
This function is for assigning a coordinate system on the workpiece coordinate
system currently being selected. This enables the workpiece coordinate system to
be changed temporarily.
The coordinate system of the rotary axis ranges from 0 to ±360°. Note that,
however, it can be displayed from 0 to 359.999.
By issuing a G code, it is possible to specify the planes for the arc, tool radius
compensation, coordinate rotation and other commands.
Using the CNC monitor, the coordinate system (current position and workpiece
coordinate position) can be set to "0" by screen operations.
Using the CNC monitor, the position counter display can be changed to "0" by
screen operations.
This function enables the tool to be returned manually to the machine's default
position (reference position).
By commanding the G code during an automatic operation, the 1st reference
position return is executed. If an intermediate point is commanded, a positioning is
made to the point at rapid traverse rate, then each axis returns to its 1st reference
position.
As in automatic 1st reference position return, by commanding the G code during an
automatic operation, an axis returns to a certain point of the machine (2nd/3rd/4th
reference position).
By issuing a G code, a machining program, which has been prepared so that the
tool starts off from the reference position and returns to the reference position, can
be checked to see whether the tool will return properly to the reference position.

When "/" (slash code) is programmed at the head of a block, and the optional block
skip input signal from the external source is turned ON for automatic operation, the
block with the "/" code is skipped.
When "/ (n:1 to 9)" is programmed at the head of a block, and the optional block
skip input n signal from the external source is turned ON for automatic operation,
the block with the "/n" code is skipped.
The commands for automatic operation can be executed one block at a time (block
stop) by turning ON the single block input signal.
F code feed commands for automatic operation can be switched to the manual
feedrate data of the machine operation board by turning ON the dry run input
signal.
When the machine lock input signal is set to ON, the CNC operations can be
executed without actually moving the NC axis.
When the "External input" signal or "Miscellaneous function lock" signal is turned
ON, the output signals of M, S, T, and B (2nd miscellaneous function) will not be
output to the PLC. This is useful when checking only travel commands in a program
check.
The program No. of the program to be operated automatically can be designated
and called up.
Blocks can be indexed by setting the program No., sequence No. and block No. of
the program to be operated automatically.
With the input of the automatic operation start signal (change from ON to OFF),
automatic operation of the program that was found by an operation search is
started by the controller (or the halted program is restarted).
This function enables the controller to be reset.
When the feed hold signal is set to ON during automatic operation, the machine
feed is immediately decelerated and stopped.
If the "Search & Start" signal is input when the memory mode is selected, the
designated machining program is searched and executed from the beginning.
Manual interrupt is a function that enables manual operations to be performed
during automatic operation.
The handle command can interrupt and be superimposed onto a command without
suspending automatic operation, and the machine can be moved by rotating the
manual pulse generator during automatic operation.
When resuming a machining program after a suspension due to tool damage or
other reasons, this function searches the program and the block to be resumed and
enables machining to be resumed from the block.
The program absolute positions are updated by an amount equivalent to the
distance by which the tool is moved manually when the manual absolute switch
signal is turned ON.
This function suspends the thread cutting cycle if a feed hold signal has been input
during thread cutting cycle.
If tapping is interrupted by a reset or emergency stop signal that is input during
tapping and the tap is left engaged inside the workpiece, the tap tool engaged
inside the workpiece can be rotated in the reverse direction so that it will be
disengaged by inputting the tap retract signal.
On the screen of the CNC monitor, the M, S and T (and B when 2nd miscellaneous
function is enabled) commands can be executed by setting numerical values and
pressing [INPUT].
This function enables MDI programs to be executed during automatic operation in
the single block stop status. When the modal status is changed in the MDI program,
the modal status in the automatic operation mode is also changed.
This function enables manual operations to be performed during automatic
operation by selecting an automatic operation mode (MDI or memory) and manual
mode (handle, step, jog or manual reference position return) simultaneously.
(Arbitrary feed based on the PLC is also possible.)

functions
When the same pattern is repeated during machining, the machining pattern is
registered as one subprogram and the subprogram is called from the main program
as required, thereby realizing the same machining easily. Efficient use of programs
is possible.
In order to execute one integrated function, a group of control and arithmetic
instructions can be used and registered as a macro program.
Using this function, machine tool builder can register their macro programs in the
NC, and a display/edit operation of these programs can be protected with password.
By inputting a user macro interrupt signal from the PLC, the program being
currently executed is interrupted and other programs can be called instead.
Programming can be given flexible and general-purpose capabilities by designating
variables instead of directly assigning numbers for addresses in programs and by
supplying the values of those variables as required when running the programs.
Arithmetic operations (adding, subtracting, multiplying and dividing) can also be
conducted for the variables.
This function calls the macro program using a pre-registered N code. The N No.
and the macro program are registered using parameter settings, and up to eight
can be registered.
The "user macro" option is required.
These functions enable drilling, tapping and other hole machining cycles to be
assigned in a simple 1-block program. Special fixed cycles must always be used in
combination with fixed cycles.
These variables enable direct reading/writing of the data between the CNC
machining program and sequence program.
When carrying out rough cutting, etc. in turning machining, using this function, only
one block is enough for a shape that normally requires several blocks. This is
useful for simplifying maching programs.
Using a program for the left or right side of an image, this function can machine the
other side of the image when a left/right symmetrical shape is to be cut.
With machines in which the base tool post and facing tool post are integrated, this
function enables the programs prepared for cutting at the base side to be executed
by the tools on the facing side.
When it is necessary to machine a complicated shape at a position that has been
rotated with respect to the coordinate system, you can machine a rotated shape by
programming the shape prior to rotation on the local coordinate system, and then
specifying the parallel shift amount and rotation angle by means of this coordinate
rotation command.
This function executes corner processing by automatically inserting a straight line
or arc in the commanded amount between two consecutive travel blocks.
When it is difficult to find the intersection point of two straight lines with a
continuous linear interpolation command, this point can be calculated automatically
by programming the command for the angle of the straight lines.
A series of cuts is performed: first, the tool departs from the center of the circle, and
by cutting along the inside circumference of the circle, it draws a complete circle,
then it returns to the center of the circle.
This function controls the swiveling of the C axis (rotary axis) so that the tool is
always pointing in the normal line direction for movements of the axis which is
selecting the plane during program operation.
This function continuously raises and lowers the chopping axis independently of
program operation. During the grinding operation, chopping can produce a better
surface accuracy than using abrasive grain.
The multi-axis, multi-part system compound control CNC system can
simultaneously run multiple machining programs independently. This function is
used in cases when, at some particular point during operation, the operations of
different part systems are to be synchronized or in cases when the operation of
only one part system is required.
The synchronizing point can be placed in the middle of the block by designating the
start point.
When a workpiece that is relatively long and thin is machined on a lathe, deflection
may result, making it impossible for the workpiece to be machined with any
accuracy. In cases like this, the deflection can be minimized by holding tools
simultaneously from both sides of the workpiece and using them in synchronization
to machine the workpiece (balance cutting). In addition, since the workpiece is
machined by two tools, the machining time is reduced.
This function performs synchronous thread cutting for the same spindle using the
1st and 2nd part systems.
The parameters set from the display can be changed using the machining
programs.
The value of the workpiece coordinate systems selected can be set or changed
using program commands.
The tool offset amounts, that are set from the display can be input using program
commands.
When tapping mode commands are issued, the CNC system is set to the internal
control modes required for tapping.
When a cutting mode command is issued, the CNC system is set to the cutting
mode that enables a smoothly cut surface to be achieved.

M system L system
To prevent machining surface distortion due to increase in the cutting load when
cutting corners, this function automatically applies an override on the cutting
feedrate so that the cutting amount is not increased for a set time at the corner.
This function decelerates and stops a motor before executing the next block, which
lowers a shock to the machine which is caused by a rapid change of feedrate, and
prevents a corner from being machined round.
This function controls the operation so the lag will be eliminated in control systems
and servo systems. With this function, improved machining accuracy can be realized,
especially during high-speed machining, and machining time can be reduced.

functions
This function compensates the error (backlash) produced when the direction of the
machine system is reversed.
Machine accuracy can be improved by compensating the errors in the screw pitch
intervals among the mechanical errors (production errors, wear, etc.) of the feed
screws.
Machine accuracy can be improved by compensating the relative error between
machine axes, such as a production error or aging.
The coordinate system can be shifted by inputting a compensation amount from the
PLC. This compensation amount will not appear on the counters (all counters
including machine position).
With commands designated during arc cutting, this function compensates
movement toward the inside of the arcs caused by a factor such as servo delay.
This compensates the axis feed error caused by ball screw thermal expansion, etc.
using the values set by the PLC.
This is a high-response and stable position control method using the servo system.
SHG control realizes an approximately three-fold position loop gain compared to
the conventional control method.
Use position feedback with a motor-side detector in ranges with high acceleration to
enable stable control. In ranges with low acceleration, use position feedback with
the machine-side detector (scale). This will make it possible to increase the position
loop gain. A machine-side detector (scale) is separately required.
This function compensates the error in protrusion shapes caused by lost motion at
the arc quadrant changeover section during circular cutting.

When the external skip signal is input during linear interpolation using the G31
command, machine feeding is stopped immediately, the remaining distance is
discarded, and the commands in the next block are executed.
This function realizes skipping by designating a combination of skip signals for each
skip command.
This function moves the tool in the direction of the tool measurement position by the
commanded value between the measurement start position and measurement
position. It stops the tool as soon as it contacts the sensor and calculates the
difference between the coordinates when the tool has stopped and the command
coordinates. It registers this difference as the tool length offset amount for that tool.
Tool life management is performed using the amount of time and the frequency a
tool is used.

Using GX Works, the sequence programs of the MELSEC CPU can be developed
and debugged.
When the servo OFF signal (per axis) is input, the corresponding axis is set in the
servo OFF state. When the moving axis is mechanically clamped, this function is
designed to prevent the servo motor from being overloaded by the clamping force.
This function enables the control axis to be released from control.
The synchronous control is a control method whereby both primary and secondary
axes are controlled with the same travel command by designating the travel command
for the primary axis also to the secondary axis. This function is assumed to be used in
such equipment as large machine tools, which drive one axis with two servo motors.
Multi-secondary-axis synchronous control function serves to drive 2 or more
secondary axes in synchronization with travel commands for the primary axis.
Even when the control axes configuring the machine are mounted at an angle other
than 90 degrees, this function enables it to be programmed and controlled in the
same way as with an orthogonal axis.
Instead of a dog switch on a machine's axis, a hypothetical dog switch is
established using a parameter to set a coordinate position to show the axis name
and the hypothetical dog position. When the machine reaches the position, a signal
is output to the PLC interface.
This function enables the feed directions and feedrates of the control axes to be
controlled using commands from the sequence program.
By setting positioning points (stations) in advance, positioning control can be
performed simply by designating a positioning point No. (station No.)
Up to 20 points (stations) can be set.
Control commands to the CNC system are assigned from the PLC. Input signals
with skip inputs that respond at high speed can also be used.
The status signals are output from the CNC system. They can be utilized by
referencing them from the PLC.
PLC window is used to read/write the operation state, axis information, parameters
and tool data of the CNC through a cyclic transmission area in the CPU shared
memory.
This function enables searching of the program to automatically start from the PLC.
The program No., block No. and sequence No. can be designated. In addition, the
currently searched details can be read.
Refer to manuals of MITSUBISHI Programmable Controller "MELSEC Q series" for
information on the function and the performance.
This middleware makes it easy to develop applications which have a Windows
interface.
APLC (Advanced Programmable Logic Controller) release is a function that allows
the user-generated C language module to be called from NC.
Control operations that are difficult to express in a sequence program can be
created with C language.
The remote monitor tool is a personal-computer-compatible software tool that
monitors information in the CNC module connected via Ethernet.

Limit switches and dogs are attached to the machine, and when a limit switch has
kicked a dog, the movement of the machine is stopped by the signal input from the
limit switch.
This function sets the prohibited area for the tool to enter. There are multiple
choices according to the prohibited range and method.
By limiting the tool nose point movement range, this function prevents the tool from
colliding with the chuck or tail stock because of a programming error.
The machine movement will decelerate and stop as soon as the interlock signal,
serving as the external input, is turned ON. When the interlock signal is turned OFF,
the machine starts moving again.
This function reduces the feedrate to the deceleration speed set by the parameter
when the external deceleration input signal has been set to ON.
Under the CE marking scheme of the European safety standards (machine directive),
the opening of any protective doors while a machine is actually moving is prohibited.
When the door open signal is input from the PLC, this function first decelerates, stops
all the control axes, establishes the ready OFF status, and then shuts off the drive
power inside the servo drive units so that the motors are no longer driven.
Insulation degradation monitor function monitors insulation degradation by
insulation resistance value calculated from leakage current values of servo motors
and spindle motors that are measured with a zerophase-sequence current
transformer (ZCT) (user-prepared), a leakage transducer (user-prepared), and an
analog/digital conversion unit (Q66AD-DG) to assist machine breakdown
prevention.
NC CPU monitors the resistance value and an alarm/warning occurs when the
value becomes less than the preset alarm/limit value. Users can utilize it by PLC
processing or combining with an insulation degradation monitor screen for GOT, a
Japanese sample of which is available (not available in other languages).
This function is used to prohibit changing the set-up parameter.
The edit lock function B or C inhibits machining program B or C (group with
machining program numbers) from being edited or erased when these programs
require protection.
This function allows the display of only a target program (label address 9000) to be
disabled for the program display in the monitor screen, etc.
The safety observation function supports the following features:
(1) Safety signal comparison between two CPUs with redundant input/output of the safety signals
(2) Redundant emergency stop in which more than one CPU monitors the
emergency stop signals to shutoff the drive's main power
(3) Speed monitoring that allows an operator to access a moving part of machine by
opening the door without shutting OFF the power
(4) Door signal observation made by two CPUs for redundantly input door signals
(5) Mode signal observation made by two CPUs by monitoring the door signal
status and speed observation mode signal status
(6) Safe torque OFF (STO) that shuts OFF power to a torque-generating motor
(7) Safe operating stop (SOS) that enables an access to a moving part without
power shutoff through standstill monitoring
(8) Safe brake control (SBC) that safely controls a holding brake through dual-channel brake control signals
(9) Safe stop 2 (SS2) that controls the OFF/ON of the standstill monitor request signal
and the delay process for deceleration through a user’s safety sequence program
This is a maintenance function which is useful for tracing the history and CNC
operation information, and analyzing trouble, etc. This information can be output as
screen displays or as files.
The data sampling function can sample the CNC internal data (speed output from the CNC
to the drive unit and feedback data from the drive unit, etc.) and output it as text data.
This function serves to back-up the parameters and other data of the CNC module.
The data can also be restored.
With this function, the servo parameters can be automatically adjusted by
connecting the CNC and MS Configurator, which is an application that runs on a
regular personal computer. (This tool is free of charge. Please contact us.)
With this function, CNC data necessary for CNC control and machine operation can
be edited by connecting the CNC and NC Configurator2, which is an application
that runs on a regular personal computer.
(Please contact us to purchase a full function version. A limited function version is
also available free of charge.)
With this function, the servo parameters can be automatically adjusted by
connecting the CNC and NC Analyzer, which is an application that runs on a
regular personal computer.
This function saves (backs up) the screen data and each controller (PLC, CNC) data to a
