代碼 231415: <location>Encoder 1: Amplitude error track A/B alarm (A^2 + B^2)
問題描述與安全警告
Siemens SINUMERIK 840D CNC 觸發了嚴重的 <location>Encoder 1: Amplitude error track A/B alarm (A^2 + B^2) 警報。需要由合格的操作員或維修技師立即處理,以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前,請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
Message value: Amplitude: %1, Angle: %2 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The amplitude (root of A^2 + B^2) for encoder 1 exceeds the permissible tolerance. Alarm value (r2124, 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 is < 300 mV (obs erve the frequency response of the encoder). A signal level of 500 mV peak value corresponds to the numerical value 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. SINAMICS-Alarms Note for sensors modules for resolvers (e. g. SMC10): The nominal signal level is at 2900 mV (2.0 Vrms). The response threshold is < 1414 mV (1.0 Vrms). A signal level of 2900 mV peak value corresponds to the numerical value of 3333 hex = 13107 dec. Note: The analog values of the amplitude error are not measured at the same time with the hardware fault output by the sensor module. See also: p0491 (Motor encoder fault response ENCODER) Remedy: - check the speed range, frequency characteristic (a mplitude characteristic) of the measuring equipment is not sufficient for the speed range. - check that the encoder cables and shielding are routed in compliance with EMC. - check the plug connections. - replace the encoder or encoder cable. - check the Sensor Module (e.g. contacts). - if the coding disk is soiled or the lighting worn, replace the encoder.
