Series: G210

Encoder 3: Encoder serial number has changed

converter

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.
