; Activate static synchronized action:
; By the setting of $R1=1
; for
; the axis Y FXS is activated
; the active torque is reduced to 10%
; and a travel motion to
; direction of the stop started
; once the stop has been recognized
; ($AA_FXS[Y]==4), the torque is
; increased to 30%
; after reaching the stop
; the torque becomes dependent
; on R0 controlled
; deselection in dependence
; on R3 and
; reverse
; normal program run:
; axis Y for the movement to
; activate synchronized action
; Movement of another axis
; Include axis Y again in the
; pathgroup
