Siemens F31501 fault code meaning
Siemens / F31501
Series: DCM-6RA80
Encoder 1: Encoder position outside the tolerance range for position tracking
DC drive
Meaning: The distance traveled while the drive/encoder was powered off exceeded the set tolerance window. The reference between the mechanical system and the encoder has been lost.
Possible causes
Source: SINAMICS DCM, Parameter Manual, firmware version 1.5 SP2 (based on 5.1 SP2) P1090
Series: G120-CU250S-2, G130-G150
Encoder 1: Encoder position outside the tolerance range for position tracking
converter
Meaning: The distance traveled while the drive/encoder was powered off exceeded the set tolerance window. The reference between the mechanical system and the encoder no longer exists.
Possible causes
