Example 4: Axial deselection of a DRF offset and a $AA_OFF position offset (1)
A DRF offset is generated in the X axis by DRF handwheel traversal. No DRF offsets are
operative for any other axes in the channel.
Program code
N10 WHEN TRUE DO $AA_OFF[X]=10 G4 F5

Example 5: Axial deselection of a DRF offset and a $AA_OFF position offset (2)
A DRF offset is generated in the X and Y axes by DRF handwheel traversal. No DRF offsets
are operative for any other axes in the channel.

12.10 Deselecting overlaid movements (DRFOF, CORROF)
Comment
; A position offset == 10 is
interpolated for the X axis.
; Only the DRF offset and the position
offset of the X axis are deselected;
the DRF offset of the Y axis is
retained.
