The AC drive detects an 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 (Pr.10,
Pr.12).
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.
