Sinumerik Alarm 20094 Axis %1 function has been aborted
Parameters:
%1 = Axis name, spindle number
Definitions:
The function has been aborted. The possible reasons for this are:
• Because a pulse disable has occurred, the torque can no longer be provided.
• The PLC has removed the acknowledgments. The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reactions:
– Mode group not ready.
– Channel not ready.
– If the axis is a single axis when this alarm is triggered, the alarm is only effective for this axis (not effective for e.g. the channel or mode group)
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
Remedy:
Check whether
• there is a pulse disable from the infeed/regenerative-feedback unit or from the PLC?
• the acknowledgement bits have been deleted by the PLC even though NCK has not requested deselection?
Program Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
