| Error ID | Short Name | Description & Common Cause | | :--- | :--- | :--- | | | Overcur Mot | Motor Overcurrent. The motor current exceeded the maximum threshold at constant speed. Check the "over current fact" parameter and nominal current settings. | | 704 | Encoder Fail | Encoder Failure. The feedback signal from the motor encoder is missing. Usually indicates a hardware failure on the encoder or the interface board. | | 705 | Speed Diff | Speed Difference. The difference between the reference speed and the actual feedback speed exceeds the allowed factor ( OVER_SPEED_FACT ). This may also trigger if the motor cannot reach the required speed despite high torque (speed command error). |
