Fast retraction from the contour (SETINT LIFTFAST, ALF)

For a SETINT statement with LIFTFAST, when the input is switched, the tool is moved away
from the workpiece contour using fast retraction.
The further sequence is then dependent on whether the SETINT statement includes an
interrupt routine in addition to LIFTFAST:
With interrupt routine:
Without interrupt routine:
544
Command: Delete assignment of the interrupt signal <n> to the NC program
(ASUP) defined with SETINT <n>
Parameter: Number of the interrupt signal
Type: INT
Range of values: 1 ... 32
Comment
; The assignment between input "3" and inter-
rupt routine "ABHEB_Z" is deleted.
After the fast retraction, the interrupt routine is executed.
Machining is stopped after fast retraction and an alarm is output.
