Axis %1 has not reached fixed stop

Parameters: %1 = Axis name, spindle number
Definitions: On attempting to traverse against a fixed stop, the programmed end position has been reached or the traversing move-
ment has been aborted. The alarm can be concealed by means of the MD37050 $MA_FIXED_STOP_ALARM_MASK.
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: 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.
Remedy: 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?
Program Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group. Restart part program.

Axis %1 travel to fixed stop still active

Parameters: %1 = Axis name, spindle number
Definitions: An attempt has been made to move an axis while it is in fixed stop or while the deselection function has not yet been
completed.
The alarm can be reprogrammed in the MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).

Remedy: 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?
Program Teileprogramm neu starten.Clear alarm with the RESET key in all channels of this mode group. Restart part program.
Continuation:
20093 Axis %1 standstill monitoring at fixed-stop end point has been triggered
Parameters: %1 = Axis name, spindle number
Definitions: 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 MD11412 $MN_ALARM_REACTION_CHAN_NOREADY (channel not ready).
Reaction: Mode group not ready.
