What to do if WEG CFW11M G2 show ground fault?
- DDanny ShepherdAug 28, 2025
If WEG DC Drives display a Ground Fault (F074), it indicates a short circuit to the ground in one or more output phases. Inspect for ground faults in wiring.

What to do if WEG CFW11M G2 show ground fault?
If WEG DC Drives display a Ground Fault (F074), it indicates a short circuit to the ground in one or more output phases. Inspect for ground faults in wiring.
What causes WEG DC Drives to show DC link overvoltage?
A DC Link Overvoltage (F022) on WEG DC Drives is caused by a supply voltage that is too high, resulting in voltage on the DC link exceeding the maximum value. Ensure that the supply voltage is within specified limits.
How to fix WEG CFW11M G2 DC Drives output overcurrent fault?
The F071 fault on WEG DC Drives, which indicates an output overcurrent, is often due to load inertia being too high or the acceleration ramp being too fast. Decrease load inertia or adjust ramp settings to resolve this.
What to do if WEG CFW11M G2 show IGBTs overload fault?
If WEG DC Drives show an IGBTs Overload Fault (F048), it means the inverter output current is too high. Reduce the inverter output current.
What to do if WEG DC Drives show motor overload?
If your WEG DC Drives display a motor overload (F072), it means the load on the motor shaft is too high. You should reduce the load on the motor.
