Note
It is not permissible to program a new position for an axis if the "Travel to fixed stop" function
has already been activated for an axis/spindle (not an analog spindle). The spindle must be
switched to position-controlled mode before the function is selected.
System variable $AA_FXS[X1] for status
This system variable provides the "Travel to fixed stop" status for the axis specified:
Value = 0: Axis not at fixed stop.
1: Fixed stop successfully approached
(axis is in fixed stop monitoring window).
2: Approach to fixed stop has failed (axis is not at fixed stop).
3: Travel to fixed stop activated.
4: Fixed stop detected.
5: Travel to fixed stop will be de-selected, the de-selection is not yet completed.
Query of the system variables in the part program initiates a preprocessing stop.
As a result of the status query in the part program, it is possible, for example, to react to an
erroneous operational sequence of the "Travel to fixed stop" function.
