F0072 fault in WEG CFW500 Drive indicates a Motor Overload. This means the calculated motor temperature model exceeded safe limits due to sustained excessive load.
Cause:
- Parameters P0156, P0157, or P0158 are configured too low in relation to the motor’s operating current.
- Overload on the motor shaft.
Remedy:
Verify motor nominal currents and check P0156, P0157, and P0158. Check mechanical load on shaft.
