代码 231811: <location>Encoder 1: Encoder serial number changed

Message value: Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The serial number of the motor encoder of a synchronous motor has changed. The change was only checked for encoders with serial number (e.g. EnDat encoders) and build-in motors (e.g. p0300 = 401) or third-party motors (p0300 = 2). Cause 1: The encoder was replaced. Cause 2: A third-party, build-in or line ar motor was re-commissioned. Cause 3: The motor with integrated and adjusted encoder was replaced. Cause 4: The firmware was updated to a version that checks the encoder serial number. Note: With closed-loop position control, the serial number is accepted when starting the adjustment (p2507 = 2). When the encoder is adjusted (p2507 = 3), the serial number is checked for changes and if required, the adjustment is reset (p2507 = 1). See also: p0491 (Motor encoder fault response ENCODER) SINAMICS-Alarms Remedy: Re causes 1, 2: Carry out an automatic adjustment using the pole positi on identification routine. First, accept the serial number with p0440 = 1. Acknowledge the fault. Initiate the pole position identification routine with p1990 = 1. Then check that the pole position identification routine is correctly executed. SERVO: If a pole position identification te chnique is selected in p1980, and if p0301 does not contain a motor type with an encoder adjusted in the factor y, then p1990 is automatically activated. or Set the adjustment via p0431. In this case, the new serial number is automatically accepted. or Mechanically adjust the encoder. Accept the new serial number with p0440 = 1. Re causes 3, 4: Accept the new serial number with p0440 = 1.
