问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Infeed: DC link voltage alarm threshold 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: Drive object: A_INF, B_INF, S_INF Reaction: NONE Acknowledge: NONE Cause: In operation, the DC link voltage has dropped to bel ow the alarm threshold. The alarm threshold is obtained from the sum of p0279 and r0296. Possible causes include: - line supply voltage dip or an other line supply fault. - overload of the infeed. - for ALM: Incorrect controller parameterization. See also: p0279 (DC link voltage offset alarm thres hold), r0296 (DC link voltage undervoltage threshold) Remedy: - check the line voltage and line supply quality. - reduce the power drawn, avoid step-like load changes - for ALM: Adapt the controller parameterization, e.g. using an automatic line supply identification (p3410 = 4, 5).
