Drilling Centered Under Shopturn - Siemens SINUMERIK 840D sl Commissioning Manual

You can switch off the alarm display using the following machine data:
MD37050 $MA_FIXED_STOP_ALARM_MASK
= 2
You can set this machine data axis-specifically in the "Machine Data" window in the "Tool
zero" operating area.
If, however, the specified force is reached during the cut-off check (i.e. travel to fixed stop is
successful), alarm 61255 "Error during cut-off: Tool break?" is issued.
Note
The "Travel to fixed stop" function can also be used when gripping the spindle (see above). If
travel to fixed stop does not succeed when gripping, an alarm will of course also be issued.
Instead of alarms 20091 and 20094, the alarm 61254 "Error during travel to fixed stop" will
be issued.
