Motion sequence for interrupt routines

Interrupt routine without LIFTFAST
Axis motion is braked along the path down to standstill (zero speed). The interrupt routine
then starts.
The standstill position is saved as interrupt position and is approached at the end of the
interrupt routine for
Interrupt routine with LIFTFAST
Axis motion is braked along the path. The
superimposed motion. If the path motion and
speed), the interrupt routine is started.
The position on the contour is saved as interrupt position where the
started and therefore the path was left.

Note
The absolute value through which the geometry axes move when quickly retracting from the
contour can be set using machine data.

LFWP
: X/Y plane
G17
: Retraction in the X direction
ALF=1
: Retraction in the Y direction
ALF=3
: Z/X plane
G18
: Retraction in the Z direction
ALF=1
: Retraction in the X direction

: Retraction in the Y direction
