6.3 Travel to fixed stop
Basic Functions
322 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Deselection
The NC recognizes the function deselection via programming of the command FXS[x]=0. Then an advance stop
(STOPRE) is internally released, since it can't be forseen where the axis will be after deselection.
The torque limitation and monitoring of the fixed stop monitoring window are canceled.
The IS DB31, ... DBX62.4 ("Activate travel to fixed stop") and DB31, ... DBX62.5 ("Fixed stop reached") are reset.
The axis will then change to position control. The followup mode of the position setpoints is ended and a
synchronization to the new actual position is carried out.
A programmed traverse motion can then be executed. This motion must lead away from the fixed stop or else the
stop or even the machine may sustain damage.
A block change is executed after the target position has been reached.

Enabling the fixed stop alarms
With the machine data:
MD37050 $MA_FIXED_STOP_ALARM_MASK
enabling the fixed stop alarms can be established as follows:
All other values ≤ 7 do not suppress any alarms.
Using the parts program command NEWCONF a new setting can be activated.
MD 37050 = 0 Fixed stop not reached (suppress Alarm 20091)
MD 37050 = 2 Fixed stop not reached ( suppress alarm 20091) and fixed stop aborted
(suppress alarm 20094)
MD 37050 = 3 Fixed stop aborted (suppress alarm 20094)
