Fault 11 Temperature monitoring
Subfault: 11.1 Description: Heat sink overtemperature | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Air circulation has been disrupted. Maximum permitted heat sink temperature exceeded. | – Check air circulation. – Ensure sufficient cooling. | |
Fan defective. Maximum permitted heat sink temperature exceeded. | Contact SEW‑EURODRIVE Service. | |
The temperature sensor is defective. Maximum permitted heat sink temperature exceeded. | Contact SEW‑EURODRIVE Service. | |
The capacity utilization is too high. Maximum permitted heat sink temperature exceeded. | – Reduce the load. – Reduce the PWM frequency. – Reduce the ambient temperature. | |
Subfault: 11.7 Description: Wire break at temperature sensor of heat sink | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Wire break at temperature sensor of heat sink. | Contact SEW‑EURODRIVE Service. | |
Subfault: 11.8 Description: Short circuit at temperature sensor of heat sink | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
A short circuit was detected at the temperature sensor of the heat sink. | Contact SEW‑EURODRIVE Service. | |
