A0764 alarm in WEG CFW500 Drive indicates the Frequency Inverter is in Sleep Mode. This means the PID controller has put the drive into a standby state because the process demand dropped below the configured sleep threshold.
Cause:
- The main PID controller is active in automatic mode, and the motor speed remained below the speed programmed in P1036 for the duration set in P1037.
Remedy:
Informational alarm status indicating sleep mode has engaged. To adjust this behavior, modify parameters P1036 (sleep speed) or P1037 (sleep delay time).
