Code 235224: <location>TM: Zero mark synchronization interrupted
Problembeschreibung & Sicherheitswarnung
Die Siemens SINUMERIK 840D CNC hat einen kritischen <location>TM: Zero mark synchronization interrupted-Alarm ausgelöst. Sofortige Aufmerksamkeit durch einen qualifizierten Bediener oder Wartungstechniker ist erforderlich, um Folgeschäden an der Ausrüstung oder verdorbene Teile während des Fertigungszyklus zu vermeiden. Stellen Sie immer sicher, dass standardmäßige Sicherheits- und LOTO-Verfahren befolgt werden, bevor Sie auf Schaltschränke zugreifen.
Offizielle Schritte zur Fehlerbehebung
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.
