Deselecting Overlaid Movements (Drfof, Corrof) - Siemens SINUMERIK 828D Programming Manual

12.10

Deselecting overlaid movements (DRFOF, CORROF)

Function
The additive work 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 commands
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.
