Cause: Circuit Breaker Error comes when rhe DC bus voltage level is not correct compared to the circuit breaker logic control (start or stop pulse) after the configured timeout. This error indicates a problem with the circuit breaker that protects the motor connected to the drive.
"CbF" fault in Schneider ATV950 drive indicate "Circuit Breaker" error. This means the circuit breaker itself might be faulty or stuck in the open position.
- Verify the circuit breaker logic control "pulse time for start and stop".
- Verify the mechanical state of the circuit breaker.
