Siemens SINUMERIK 840D sl Programming Manual

The position on the contour is saved as interrupt position where the LIFTFAST motion is
started and therefore the path was left.
The interrupt routine with LIFTFAST and ALF=0 behaves in precisely the same way as the
interrupt routine without LIFTFAST.
Note
The absolute value through which the geometry axes move when quickly retracting from the
contour can be set using machine data.
