Description
The drive unit at contact arg is close to the temperature limit. The contact is connected to drive unit at unit position arg and node arg to drive module arg .
Consequences
It is possible to continue, but the difference from the maximum allowable temperature is too small to sustain long-term operation.
Possible causes
- The cooling fan is faulty or the airflow is blocked.
- The cooling blades are covered with dust, which reduces the cooling effect.
- The ambient temperature may be too high.
- The torque is too high for a long time during contact operation.
Recommended actions
- Verify that the fan is running and that airflow is not blocked.
- Clean the cooling blades.
- Please check whether the ambient temperature exceeds the rated temperature value of the cabinet.
- If possible, please rewrite the user program to reduce the number of emergency accelerations and emergency decelerations.
- Reduce static torque caused by gravity or external forces.
