F0763 fault in WEG CFW500 Drive indicates a High Level of the Main PID Process Variable. This means the drive switched off the motor because the process feedback sensor remained above the safe threshold for too long.
Cause:
- Parameter P1030 is programmed for 2, and the process variable value has exceeded the threshold in P1033 for the time programmed in P1034.
Remedy:
Check for high limits in the process line (overpressure, high flow, etc.). Verify parameters P1033 and P1034.
