Fast retraction from the contour (SETINT LIFTFAST, ALF)

Function
For a SETINT instruction 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 instruction includes an
interrupt routine in addition to LIFTFAST:
With interrupt routine:
Without interrupt routine:
Syntax
SETINT(<n>) PRIO=1 LIFTFAST
SETINT(<n>) PRIO=1 <NAME> LIFTFAST

After the fast retraction, the interrupt routine is executed.
Machining is stopped after fast retraction and an alarm is output.
Command: Assign input <n> to an interrupt routine. The assigned
interrupt routine starts when input <n> switches.
Parameter: Input number
