Delta vfd-f series frequency converter maintenance: cf37 AC motor driver detects abnormal line, Isum analog / digital line, Please contact us for maintenance of delta vfd-f series frequency converter: cf38 AC motor driver detects abnormal line, temperature sensor is abnormal, and report for repair Maintenance of delta vfd-f series frequency converter: GFF grounding protection line acts
When the AC motor driver detects that the output terminal is grounded and the grounding current is higher than 50% of the rated current of AC motor driver
Note: this protection is for AC motor drives and not for human bodies
Check whether the wiring with the motor is short circuited or grounded, determine whether the power module of IGBT module is damaged, and check whether the wiring at the output side is poorly insulated
