Siemens A32811 fault code meaning

Series: DCM-6RA80

Encoder 2: Encoder serial number has changed

DC drive

Meaning: The encoder serial number has changed. Only encoders with serial numbers (e.g., EnDat encoders) are checked for changes. - Encoder replacement.

Possible causes

Series: G120-CU250S-2

Encoder 2: Encoder serial number changed

converter

Meaning: The encoder serial number has changed. Only encoders with serial numbers (e.g., EnDat encoders) are checked for changes. - Encoder replacement.

Possible causes

Series: G130-G150, S120-S150

Encoder 2: Encoder serial number has changed

converter

Meaning: The encoder serial number has changed. Only encoders with serial numbers (e.g., EnDat encoders) are checked for changes. - Encoder replacement.

Possible causes

Series: S200

Encoder 2: Encoder serial number has changed

servo drive

Meaning: The encoder serial number has changed. This check applies only to encoders with a serial number (for example, EnDat encoders). - The encoder has been replaced. Note: With position control, the serial number is transferred when calibration starts (p2507 = 2). After encoder calibration is complete (p2507 = 3), the serial number is checked for changes.
