Flexible NC programming
1.14 Interrupt routine (SETINT, DISABLE, ENABLE, CLRINT)
Deactivate/reactivate interrupt routine, DISABLE, ENABLE
You can deactivate interrupt routines in the NC program with DISABLE(n) and reactive
them with ENABLE(n) (n stands for the input number).
The input/routine assignment is retained with DISABLE and reactivated with ENABLE.
Reassign interrupt routines
If a new routine is assigned to an assigned input, the old assignment is automatically
canceled.
Example:
N20 SETINT(3) PRIO=2 LIFT_Z
...
...
N120 SETINT(3) PRIO=1 LIFT_X
Clear assignment, CLRINT
Assignments can be cleared with CLRINT(n).
Example:
N20 SETINT(3) PRIO=2 LIFT_Z
N50 CLRINT(3)
The assignment between input 3 and the routine LIFT_Z is cleared.
Rapid lift from contour, LIFTFAST
When the input is switched, LIFTFAST retracts the tool rapidly from the workpiece
contour.
