Siemens A7001 fault code meaning

Series: 6RA70

Connection between the electronic board and EEPROM on the A7009 backplane

DC drive

Meaning: Whether the parameter values stored in EEPROM are within the permissible range. Whether the data is stored correctly in EEPROM. For this purpose, the values are read back and checked for correctness after transfer to the module. Whether the checksum of the nonvolatile process data in EEPROM is correct. Possible causes for all fault types: Excessive interference associated with EMC (e.g., due to contactors without protection, unshielded cables, or insecure shield connections). r047, indices 002 ~ 016: Connection fault between 1 and EEPROM. Possible fault causes:
