Code M01-0280: APLC password mismatch

Problembeschreibung & Sicherheitswarnung

Die Mitsubishi M800/M80 CNC hat einen kritischen APLC password mismatch-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

Details The APLC authentication password is inconsistent. Remedy  Contact the machine tool builder. High-cycle sampling disabled 0290 Details  The drive unit's hardware or software does not conform to the high-cycle sampling mode.  High-cycle data are not used even when high-cycle samp ling has been set.  High-cycle sampling was attempted while the axis targeted for high-cycle sampling was moving.  High-cycle sampling was attempted during speed monitor mode.  High-cycle sampling was attempted while any of the following operations is bein g executed: Dog-type zero point return, absolute position setting, synchronous tapp ing, spindle synchronization, hobbing, tool spindle synchronization IC. Remedy  The software or hardware does not conform to the function. Contact service center.  Set data for high-cycle sampling.  Execute high-cycle sampling af ter stopping the axis ta rgeted for high-cycle sampling.  Execute high-cycle sampling after cancelling the speed monitor mode.  Execute high-cycle sampling after stopping the currently executed functions. N/A during high-cycle sampling 0291 Details  An attempt to activate "Speed monitor mode" was made during the high-cycle sampling mode.  An attempt to change the gear signal was made during the high-cycle sampling mode.  An attempt to execute spindle orientation was made during the high-cycle sampling mode.  Spindle detach was attempted during the high-cycle sampling mode.  Any of the following operations was attempted during the high-cycle sampling mode: Dog-type zero point return, absolute position setting, spindle/C axis ch angeover, synchronous tapping, spindle synchronization, hobbing, or tool spindle synchronization IC. Remedy  Change the speed monitor mode signal back, finish high-cycle sampling, and then select the speed mon- itor mode.  Change the gear signal back, finish high-cycle sampling, and then change the gear.  Change the spindle orientation signal back, finish high-cycle sampling, and then execute orientation.  Change the spindle detach signal back, finish high-cycle sampling, and then carry out spindle detachment.  Execute the operation after terminating high-cycle sampling. Invalid cmd during param write 0292 (Axis name) Details A function which is unavailable during parameter write was commanded.  Spindle/C axis changeover  Speed observation mode signal ON  High-speed synchronous tapping  PLC axis indexing Remedy  Cancel the write of the parameter.  Command the following functions after the parameter write is completed. - Spindle/C axis changeover - Speed observation mode signal ON - High-speed synchronous tapping - PLC axis indexing SP orient. Z detection error 0301 Details Z phase detection has failed to be completed durin g execution of proximity-switch orientation. Remedy  Check for a failure of the proximity switch.
