Please inform the authorized personnel/service department.
Check the following:
• Has the axis at the fixed stop also been moved by a traversing movement of geometry
axes?
• Is a selection carried out even though the axis is stationary at the stop?
• Has the deselection process been interrupted by a RESET?
• Has the PLC switched the acknowledgement signals?
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 standstill monitoring at fixed-stop end point has been triggered
%1 = Axis name, spindle number
The position of the axis has been beyond the zero speed window ever since selection has
been completed.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Please inform the authorized personnel/service department.
• Check the mechanical components, e.g. has the stop broken away? Has the part to be
clamped given way?
• Position window for zero speed control too small (37020 MD:
$MA_FIXED_STOP_WINDOW_DEF) (43520 setting data:
$SA_FIXED_STOP_WINDOW). Default is 1 mm in each case.
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 function has been aborted
%1 = Axis name, spindle number
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).
- Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
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?
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
