官方故障排除步驟
Parameters: %1 = Axis name, spindle number Definitions: The signals of the currently active position actu al value encoder (NC/PLC interface signal DB31,... DBX1.5 = 1 (Position measuring system 1) or DB 31,... DBX1.6 = 1 (Position measuring system 2)) are missing, do not have the same phase, or exhibit grounding/short-circuit. The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready). For PROFIdrive only: MD36310 $MA_ENC_ZERO_MONITORING >100 replaces the existing PowerOn alarm by the Reset alarm 25010. Reaction: Mode group not ready. The NC switches to follow-up mode. Channel not ready. NC Start disable in this channel. Axes of this channel must be re-referenced. Interface signals are set. Alarm display. NC Stop on alarm. Channel not ready. Remedy: Please inform the authorized personnel/service depar tment. Check measuring circuit connectors for correct contacting. Check encoder signals and replace the encoder if faults are found. Monitoring can be switched off by setting MD36310 $MA_ENC_ZERO_MONITORING[n] to 100 (n = encoder number: 1,2). Program Continuation: Switch control OFF - ON.
