PWM temporarily stops outputting for 30 ms, and then continues to output normally. If
time that hardware triggers a second time of over-current short to ground is shorter
than 30 ms, PWM stops outputting.
Manual reset
5 seconds after software checks output current is smaller than 50% of rated current
Yes
Check the motor insulation value with megger. Replace the motor if the insulation is
poor.
Troubleshoot the short circuit.
Replace the cable.
If the motor cable length exceeds 100 m, decrease the setting value for carrier
frequency.
Take remedies to reduce stray capacitance.
Verify the wiring and grounding of the communication circuit. It is recommended to
separate the communication circuit from the main circuit, or wire in 90 degree for
effective anti-interference performance.
Cycle the power after checking the status of motor, cable and cable length. If GFF still
exists, return to the factory for repair.

Over-current at stop
Action and Reset
300% of the drive's rated current
Time that triggers a second time of over-current is shorter than 30 ms
PWM temporarily stops outputting for 30 ms, and then continues to output normally. If
time that hardware triggers a second time of over-current is shorter than 30 ms, PWM
stops outputting.
Manual reset
5 seconds after output current is smaller than 37.6% of rated current
Yes
Verify the wiring of the control circuit and the wiring/grounding of the main circuit to
prevent interference.
Check if other fault codes such as cd1–cd3 occur after cycling the power. If yes, return
to the factory for repair.
