问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Drive: APC filter natural frequency > Shannon frequency 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: %1 Drive object: SERVO Reaction: NONE (OFF1, OFF2, OFF3) Acknowledge: IMMEDIATELY (POWER ON) Cause: One of the filter natural frequencies is greater than the Shannon frequency. The Shannon frequency is calculated according to the following formula: 0.5 / (p0115[1] * x) Fault value (r0949, interpret hexadecimal): Bit 0: Filter 1.1 (p3711, p3713), x = 1 Bit 4: Filter 2.1 (p3721, p3723), x = p3706 Bit 5: Filter 2.2 (p3726, p3728), x = p3706 Bit 8: Filter 3.1 (p3731, p3733), x = p3707 Bit 9: Filter 3.2 (p3736, p3738), x = p3707 Bit 16... 32: Data set number (starting from zero) Remedy: - reduce the numerator or denominator natural frequency of the filter involved. - reduce the speed controller sampling time (p0115[1]) or the sub-sampling (p3706, p3707). - switch out the filter involved (p3704).
