Overlaid movements $AA_OFF settable (SW 6 and later)

Overlaid movements up to SW 5.3
Whatever the current tool and processing level, an overlaid movement is possible for each
axis of the channel via the system variable $AA_OFF. The offset is retracted immediately,
whether the axis is programmed or not. This allows a clearance control to be implemented.
The type of calculation is defined with the axial machine data as follows:
MD36750 $MA_AA_OFF_MODE (Effect of value assignment for axial override in case of
synchronized actions)
Bit0 = 0: proportional calculation (absolute value)
Bit0 = 1: integrating calculation (incremental value)

; Subroutine for clearance control ON
; Polynomial definition: The offset is applied in
the range 0.2 to 0.5
; Clearance control active
; Disable axis X when limit value is overshot
; Subroutine for clearance control OFF
; Cancel clearance control synchronized action
; Cancel limit range check
; Main program
; MD36750 is set to 1 before Power On for
integrating machining
; Limiting value for the offset:
; Clearance control ON
; Clearance control OFF
