Description
The temperature of the rectifier unit at drive unit position arg is too high.
Consequences
No operation can be performed until the rectifier has cooled down. The system enters the "motor off" state.
Possible causes
- The cooling fan may be faulty, or there may be poor airflow.
- The ambient temperature may be too high.
- The system may be in an excessively high torque state for a long time during system operation.
Recommended actions
- Verify that the fan is running and airflow is not blocked.
- Verify that the ambient temperature does not exceed the rated temperature of the cabinet.
- If possible, rewrite the user program to reduce the number of hard accelerations and hard decelerations.
- Reduce static torque caused by gravity or external forces.
