ocn Over current occurs during constant speed fault in delta VJ series Drive

-

 How can resolve problem ocn Over current occurs during constant speed fault in delta VJ series Drive ?

1. Check if the insulation of the wire from U-V-W to the hybrid servo motor is bad.
2. Check if the hybrid servo motor is stalled.
3. Such errors occur when the red light of PG card flashes. The causes of these errors could be loose contact/ disconnection between encoder, motor drive and motor.
4. When such errors occur at the beginning, during or at the end of pressure/ flow command
