Over current

Abnormal increase

in current.

1. Check whether the motors horsepower corresponds to the

AC drive output power.

2. Check the wiring connections between the AC drive and

motor for possible short circuits.

3. Increase the Acceleration time.

4. Check for possible excessive loading conditions at the motor.

5. If there are any abnormal conditions when operating the AC

drive after short-circuit being removed, it should be sent back

to manufacturer.

Over voltage

The DC bus voltage

has exceeded its

maximum allowable

value.

1. Check whether the input voltage falls within the rated AC

drive input voltage.

2. Check for possible voltage transients.

3. Bus over-voltage may also be caused by motor regeneration.

Either increase the decel time or add an optional brake

resistor.

4. Check whether the required brake power is within the

specified limits.
