A0768 alarm in WEG CFW701 Drive indicates a Broken Belt Detected. This means the inverter senses high motor speed with unusually low torque, suggesting the mechanical transmission belt has snapped.
Cause:
- Parameter P1046 is programmed in 1, the motor is running faster than the speed programmed in P1047, and the motor torque is remaining below the torque value programmed in P1048 for the time programmed in P1049.
Remedy:
Check the mechanical coupling belt/pulley state. Verify the parameter configurations for P1046, P1047, P1048, and P1049.
