Encoder (PG) Feedback Loss

The encoder cable is disconnected or wired incorrectly.

Examine for wiring errors or disconnected wires in the encoder cable, and repair problems.

The encoder is not receiving power.

Examine the encoder power supply.

The holding brake is stopping the motor.

Release the holding brake.
Note:

  • The drive detects this error if it does not receive the speed detection pulse signal from the encoder in the detection time set in F1-14 [Encoder Open-Circuit Detect Time].

  • If the drive detects this error, the terminal assigned to H2-01 to H2-03 = 10 [MFDO Function Select = Alarm] will activate.

  • If the drive detects this error, it will operate the motor as specified by the stopping method set in F1-02 [PG Open Circuit Detection Select].
