代碼 232443: <location>Encoder 2: Signal le vel C/D unipolar outside tolerance

Message value: Fault cause: %1 bin Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The unipolar level (CP/CN or DP/DN) for enc oder 2 is outside the permissible tolerance. Alarm value (r2124, interpret binary): Bit 0 = 1: Either CP or CN outside the tolerance. Bit 16 = 1: Either DP or DN outside the tolerance. The unipolar nominal signal level of the encoder must lie in the range 2500 mV +/- 500 mV. The response thresholds are < 1700 mV and > 3300 mV. Note: The signal level is not evaluated unless the following conditions are satisfied: - Sensor Module properties available (r0459.31 = 1). - Monitoring active (p0437.31 = 1). Remedy: - check that the encoder cables and shielding are routed in compliance with EMC. - check the plug connections and contacts. - are the C/D tracks connected co rrectly (have the signal lines CP and CN or DP and DN been interchanged)? - replace the encoder cable.
