Programming

Assignment Interrupt signal ↔ part program
The assignment interrupt signal ↔ part program is done with the command SETINT.
Example
Program code
...
N20 SETINT(3) ABHEBEN_Z
...
Together with SETINT additionally the following commands can be programmed:
•
LIFTFAST
When the interrupt signal arrives, a "Fast retraction of the tool from the contour" is executed before the
interrupt routine starts. The motion direction for the fast retraction is specified by the program instruction ALF.
•
BLSYNC
Upon receiving the interrupt signal, the current program block is processed and only then is the interrupt
routine started.
Note
The assignment interrupt signal ↔ part program is cleared when the following happens:
•
•
Priorities
If several SETINT instructions are in the part program and therefore several signals can be simultaneously
received, the assigned interrupt routines must be allocated priorities that define the sequence in which the
interrupt routines are executed:
PRIO=<value>
There are priorities from 1 to 128. Priority 1 corresponds to the highest priority.
Example
Program code
...
N20 SETINT(3) PRIO=2 ABHEBEN_Z
N30 SETINT(2) PRIO=2 ABHEBEN_X
...
The interrupt routines are executed in the sequence of the priority values if the inputs become available
simultaneously (are energized simultaneously): First "ABHEBEN_Z", then "ABHEBEN_X".
