Troubleshooting

Motor will not stop when the speed adjust
potentiometer is full counterclockwise

Turn the MIN SPD trimpot CCW until the motor stops (page 28).

Motor runs in the opposite direction

Open or close the DIR switch so that the motor runs in the
opposite direction.

Motor slows under load

1. Check that the drive has been correctly calibrated for the
motor.
2. Check that the motor is not overloaded.
3. Readjust the GAIN slightly CW until motor runs at proper

speed (page 30).

Motor is unstable under load

Reduce the GAIN setting until motor speed is stabilized (page
30).
