问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>CU: System overload calculated for the complete target topology 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: All objects Reaction: NONE Acknowledge: NONE Cause: A system overload was calculated based on a complete active target topology. Alarm value (r2124, interpret decimal): 2: Computing time load too high. 6: Cyclic computing time load too high. Remedy: - reduce the sampling time. - only use one data set (CDS, DDS). - de-activate the function module. - de-activate the drive object. - remove the drive object from the target topology. Note: After executing the appropriate counter-measure, a new calculation must be initiated with p9974 = 1.
