代码 235224: <location>TM: Zero mark synchronization interrupted
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>TM: Zero mark synchronization interrupted 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: TM41 Reaction: NONE Acknowledge: NONE SINAMICS-Alarms Cause: The zero mark synchronization with the encoder to be emulated was interrupted. Alarm value (r2124, interpret decimal): 0: The encoder is not in the ready state (e.g. encoder parked) 1: An absolute encoder was connected. 2: The encoder r0479[0...2] interconnected with C I: p4420 is already communicating with another TM41 (precisely one TM41 can be interconnec ted with a specific r0479[0...2]). 3: The BICO interconnection to Terminal Modu le 41 (TM41) was removed (CI: p4420 = 0 signal). 4: The encoder connected with CI: p4420 has carrie d out an EDS changeover (this operation is not supported, set p4420 to 0 and interconnect again). 5: The maximum number of revolutions of the encoder was exceeded. 6: Encoder in an invalid state. 7: Encoder in an invalid state. 8: Encoder in an invalid state (the encoder is not parameterized or the interconnected signal source is not in the cyclic state). Remedy: None necessary. - if the encoder changes into the ready state, t hen a synchronization operati on that was previously interrupted is carried out again. - if the synchronization was interrupted due to t he maximum permissible sy nchronization duration, then a new synchronization is not carried out. - for an absolute encoder, no synchronization is carried ou t, the zero mark is always output at the zero revolution of the TM41.
