Troubleshooting and error codes
| Fault | Cause | Remedy |
|---|---|---|
| Overcurrent | Motor current too high. | Reduce the load or increase the motor size. Check motor and cable for faults. |
| Overtemperature | Brake resistor temperature too high. | Ensure adequate ventilation. Check brake resistor connection and size. Reduce braking duty. |
| Communication error | Loss of communication between control unit and module. | Check fiber optic cables. Restart the control unit and module. |
| DC link overvoltage | Excessive braking energy. | Check brake resistor size and connection. Ensure proper braking control. |
