Please inform the authorized personnel/service department.
• Check the axis type.
• Check MD 37000.
• Is a machine axis movement missing in the approach block?
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 has not reached fixed stop
%1 = Axis name, spindle number
On attempting to traverse against a fixed stop, the programmed end position has been
reached or the traversing movement has been aborted. The alarm can be concealed by
means of the machine data $MA_FIXED_STOP_ALARM_MASK.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- 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.
Correct the part program and the settings:
• Has the traversing block been aborted?
• If the axis position does not correspond to the programmed end position, then correct
the end position.
• If the programmed end position is in the part, the triggering criterion must be
checked.
• Has the contour deviation leading to triggering been dimensioned too large? Has the
torque limit been set too high?
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Axis %1 travel to fixed stop still active
%1 = Axis name, spindle number
An attempt has been made to move an axis while it is in fixed stop or while the deselec-
tion function has not yet been completed.
The alarm can be reprogrammed in the MD ALARM_REACTION_CHAN_NOREADY
(channel not ready).
- 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.
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?
