System variable for status: $AA_FXS[ axis ]
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 is deselected. The deselection is not yet completed.

selection/deselection.
