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.
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
signal should be positive. SW7 can be used to set the right polarity.
