Troubleshooting
Motor does not run
1. Check for blown fuses or tripped circuit breaker.
2. Verify that the speed adjust potentiometer is not set to zero
position.
3. Verify that the enable/disable or run/brake terminals are not
shorted to COM.
4. Verify that the drive is receiving power from the AC or DC
voltage input. The green POWER ON LED should be lit when
AC or DC voltage input is applied.
5. Check that the drive is not in current limit. The red TQ LIMIT
LED must be off. If the red TQ LIMIT LED is on, verify that
the motor is not jammed. It may be necessary to increase the
TQ LIMIT setting.
6. Check that the encoder, if installed, does not draw current in
excess of 20 mADC.
Fuse or circuit breaker blows
1. Check all wiring for shorts, grounds, or misconnections.
2. Check that the drive is configured to match the motor rating.
3. Check that the motor is not jammed or restricted from
movement.
4. Check that the fuse size is correct for the motor being driven.
Motor runs too fast at the maximum speed setting
Check that the MIN SPD and MAX SPD settings are not set too
high (page 28).
