Adjustment outputs
With these outputs and a potentiometer, the user can obtain a variable analog
voltage for adjusting the Power Drive System during setup.
The voltage, with no load, at these pins is ±15 V DC.
The electrical circuit necessary to obtain a reference voltage and the
recommended resistance values to obtain an approximate range of ±10 V DC
for the Vref are described next:
