Brake chopper not ready for operation. | – Switch the device off and on again. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Error: 44.7 (2C07hex | 11271dec) Description: Hardware fault | ||
|---|---|---|
|
| |
Cause | Measure | |
The hardware of the power section has detected a fault. It is not possible to pinpoint the fault. | – Switch the device off and on again. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Error: 44.8 (2C08hex | 11272dec) Description: Current measurement error | ||
|---|---|---|
|
| |
Cause | Measure | |
