Sinumerik Alarm 20091 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 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).
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:
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 Continuation:
Clear alarm with the RESET key in all channels of this mode group. Restart part program.
