代码 232126: <location>Encoder 2: Amplitude AB too high
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Encoder 2: Amplitude AB too high 警报。需要由合格的操作员或维修技师立即处理,以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前,请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
Message value: Amplitude: %1, Angle: %2 Drive object: All objects Reaction: A_INFEED: NONE SERVO: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2) VECTOR: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2) Acknowledge: PULSE INHIBIT Cause: The amplitude (root of A^2 + B^2 or |A| + |B|) for encoder 2 exceeds the permissible tolerance. Fault value (r0949, interpret hexadecimal): yyyyxxxx hex: yyyy = Angle xxxx = Amplitude, i.e. root from A^2 + B^2 (16 bits without sign) The nominal signal level of the encoder must lie in the range 375 mV to 600 mV (500 mV -25/+20 %). The response threshold for (|A| + |B|) is > 1120 mV or the root of (A^2 + B^2) > 955 mV. A signal level of 500 mV peak value corresponds to the numerical value of 299A hex = 10650 dec. The angle 0... FFFF hex corresponds to 0... 360 degrees of the fine position. Zero degrees is at the negative zero crossover of track B. Note: The analog values of the amplitude error are not measured at the same time with the hardware fault output by the sensor module. SINAMICS-Alarms Remedy: - check that the encoder cables and shielding are routed in compliance with EMC. - replace the encoder or encoder cable.
