Over-current
Abnormal increase in current.
1. Check if the motor power corresponds with the AC
motor drive output power.
2. Check the wiring connections to U/T1, V/T2, and
W/T3 for possible short circuits.
3. Check the wiring connections between the AC motor
drive and motor for possible short circuits, and for
short to ground.
4. Check for loose contacts between the AC motor drive
and the motor.
5. Increase the Acceleration Time.
6. Check for possible excessive loading on the motor.
