Grounding circuit protections.
This message is displayed when the AC drive detects that the output terminal is grounded and that thegrounding current exceeds 50% of the AC drive’s rated current. Note: This is aprotection towards the ACdrive rather than the personnel.
Check whether the connection to the motor is short circuited or grounded
Check whether the IGBT power module is functioning right
Check whether the wiring on the output side is of poor insulation
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
