Siemens SINUMERIK 840D sl Programming Manual

Meaning
CLRINT(<n>): Command: Delete assignment of the interrupt signal <n> to the NC program
(ASUP) defined with SETINT <n>
<n>: Parameter: Number of the interrupt signal
Type: INT
Range of values: 1 ... 32
Example
Program code Comment
N20 SETINT(3) PRIO=2 ABHEB_Z
...
N50 CLRINT(3) ; The assignment between input "3" and inter-
rupt routine "ABHEB_Z" is deleted.
3.3.6 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: After the fast retraction, the interrupt routine is executed.
Without interrupt routine: Machining is stopped after fast retraction and an alarm is output.
