Error: 44.1 (2C01hex | 11265dec) Description: Error at switched-mode power supply | ||
|---|---|---|
| Response: Remote – critical error | |
Cause | Measure | |
Switched-mode power supply in power section is error. | Contact SEW‑EURODRIVE Service. | |
Error: 44.2 (2C02hex | 11266dec) Description: Overcurrent phase U | ||
|---|---|---|
| Response: Remote – critical error | |
Cause | Measure | |
The connected motor is too large. | Connect a smaller motor. | |
Acceleration too high. | Reduce the acceleration. | |
A short circuit has occurred. | – Remove the short circuit on the motor connection. – Check the motor phases. | |
There is a problem with the output filter. | – Activate the output filter during startup of the drive train. – Check assignment of output filter and inverter. | |
Output stage defective. | Contact SEW‑EURODRIVE Service. | |
