6.4 Faults at the power supply module
6.4.1 Fault 49 Power supply module
Subfault: 49.1
Description: Unknown supply unit
Response: Remote – critical fault
Cause Measure
Failed to identify supply unit Contact the SEW-EURODRIVE Service.
Subfault: 49.2
Description: EEPROM memory – hardware faulty
Response: Remote – critical fault
Cause Measure
EEPROM cannot be read; initialization error. Contact the SEW-EURODRIVE Service.
Subfault: 49.3
Description: Internal voltage supply
Response: Remote – critical fault
Cause Measure
At least one internal supply voltage is faulty. Switch the power off and on again. Contact the
SEW‑EURODRIVE Service if the error is still present.
Subfault: 49.4
Description: DC 24 V supply voltage
Response: Remote – critical fault
Cause Measure
24V supply below min. specified 24V input voltage Check the 24V supply, switch power supply off and on again.
Contact the SEW‑EURODRIVE Service if the error is still
present.
Subfault: 49.5
Description: Fault in hardware component of analog to digital conversion
Response: Remote – critical fault
Cause Measure
Measured DC link values outside valid range or voltage supply
of transducers defective.
Contact the SEW-EURODRIVE Service.
Subfault: 49.6
Description: CRC error – power section data
Response: Remote – critical fault
Cause Measure
Device not yet calibrated. Contact the SEW-EURODRIVE Service.
Initialization error Contact the SEW-EURODRIVE Service.
Subfault: 49.7
Description: EEPROM data error
Response: Remote – critical fault
Cause Measure
Calibration data not plausible. Contact the SEW-EURODRIVE Service.
Subfault: 49.8
Description: DC link overvoltage
Response: Remote – critical fault
Cause Measure
Maximum permitted DC link voltage limit exceeded – Check brake chopper function, braking resistor, and regener-
ative energy.
– Check project planning of the axis system.
