TEST POINTS FOR PCTENTIOMETERS 
Once the poientiometer adjustment is complete, the resistance values can be measured for future 
adjustments. Test points of the potentiometerw ipers are provided and are located next to all four 
potentiometers. Make sure the power is off, then measure the resistance between ground and test 
points.

These modesc an be selectedb y the DIP switchesa ccordingt o the chart in the functionabl lockd iagram.

* Open loop mode 
* Tachometer mode 
* HALL velocity mode 
See section "G" for more information. 
VELOCITY CONTROL USING HALL SENSORS 
(HALL velocity mode) 
The frequencyo f HALL sensors is proportionatlo the motor speed. In B80A amplifiers eries internal 
circuitry decodes velocity information. This analog signal is available for closed loop velocity control. 
HALL velocity mode can be selected by the DIP switches according to the chart in the block diagram. 
Since the frequency of HALL sensor signals is not very high, this mode does not provide good velocity 
control below speeds 300 RPM. The optimal response can be achieved by adjusting Pot 1 loop gain. 
Increasei t by turning Pot 1 clockwiseu ntil the motor breaks into oscillation,t hen turn it back slighfly. 
Changingt he velocityl oop integratorv alue (SWg)m ight improvet he response. The polarityo f velocity 
signal should be the same as the polarity of input signal. For positive input signal the velocity monitor

See section "G" N/A TEST POINTS FOR PCTENTIOMETERS Once the poientiometer adjustment is complete, the resistance values can be measured for future adjustments. Test points of the potentiometerw ipers are provided and are located next to all four potentiometers. Make sure the power is off, then measure the resistance between ground and test points. OPERATING MODE SELECTION These modesc an be selectedb y the DIP switchesa ccordingt o the chart in the functionabl lockd iagram. " Current mode * Open loop mode * Tachometer mode * HALL velocity mode See section "G" for more information. VELOCITY CONTROL USING HALL SENSORS (HALL velocity mode) The frequencyo f HALL sensors is proportionatlo the motor speed. In B80A amplifiers eries internal circuitry decodes velocity information. This analog signal is available for closed loop velocity control. HALL velocity mode can be selected by the DIP switches according to the chart in the block diagram. Since the frequency of HALL sensor signals is not very high, this mode does not provide good velocity control below speeds 300 RPM. The optimal response can be achieved by adjusting Pot 1 loop gain.

The polarityo f velocity signal should be the same as the polarity of input signal. For positive input signal the velocity monitor Sold & Serviced By:
