コード 232123: <location>Encoder 2: Signal le vel A/B unipolar outside tolerance

Message value: Fault cause: %1 bin Drive object: All objects Reaction: A_INFEED: NONE SERVO: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) VECTOR: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3) Acknowledge: IMMEDIATELY SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Cause: The unipolar level (AP/AN or BP/BN) for enc oder 2 is outside the permissible tolerance. Fault value (r0949, interpret binary): Bit 0 = 1: Either AP or AN outside the tolerance. Bit 16 = 1: Either BP or BN 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: - make sure that the encoder cables and shie lding are installed in an EMC-compliant manner. - check the plug connections and contacts. - check the short-circuit of a signal cable with mass or the operating voltage. - replace the encoder cable.
