Deselecting overlaid movements (DRFOF, CORROF)

The additive zero offsets set by means of handwheel traversal (DRF offsets) and the position
offsets programmed using system variable $AA_OFF[<axis>] can be deselected using the part
program statements DRFOF and CORROF.
Deselection triggers a preprocessing stop and the position component of the deselected
overlaid movement (DRF offset or position offset) is written to the position in the basic
coordinate system (in other words, no axes are traversed). The value of system variable
$AA_IM[<axis>] (current machine coordinate system setpoint of an axis) does not change; the
value of system variable $AA_IW[<axis>] (current workpiece coordinate system setpoint of an
axis) does change, because it now contains the deselected component from the overlaid
movement.

Non-modal suppression of all programmable and settable
frames
G153 has the same effect as G53 and also suppresses the
entire basic frame ($P_ACTBFRAME).
SUPA has the same effect as G153 and also suppresses:
● Handwheel offsets (DRF)
● Overlaid movements
● External zero offset
● PRESET offset
Modal deactivation of all settable frames (G54 to G57,
G505 to G599) if G500 does not contain a value.
Without axis details, a deletion of the programmable frames
acts.
