Código 231131: <location>Encoder 1: Deviation, position incremental/absolute too large

Message value: %1 Drive object: All objects Reaction: A_INFEED: NONE SERVO: ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2) VECTOR: ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2) Acknowledge: PULSE INHIBIT Cause: Absolute encoder: When cyclically reading t he absolute position, an ex cessively high difference to the incremental position was detected. The absolute position that was read is rejected. Limit value for the deviation: - EnDat encoder: Is supplied from the encoder and is a minimum of 2 quadrants (e.g. EQI 1325 > 2 quadrants, EQN 1325 > 50 quadrants). - other encoders: 15 pulses = 60 quadrants. Incremental encoder: When the zero pulse is passed, a deviation in the incremental position was detected. For equidistant zero marks, the following applies: - The first zero mark passed supplies the referenc e point for all subsequent checks. The other zero marks must have n times the distance referred to the first zero mark. For distance-coded zero marks, the following applies: - the first zero mark pair supplies the reference poi nt for all subsequent checks. The other zero mark pairs must have the expected distan ce to the first zero mark pair. Fault value (r0949, interpret decimal): Deviation in quadrants (1 pulse = 4 quadrants). See also: p0491 (Motor encoder fault response ENCODER) Remedy: - check that the encoder cables are routed in compliance with EMC. - check the plug connections. - replace the encoder or encoder cable. - check whether the coding disk is dirty or there are strong ambient magnetic fields. - adapt the parameter for the distance between zero marks (p0425). - if message output above speed threshold, reduce filter time if necessary (p0438).
