Sequence
Create interrupt routine as subprogram
The interrupt routine is identified as a subprogram in
the definition.
Example:
PROC LIFT_Z
N10…
N50 M17
Program name LIFT_Z, followed by the NC blocks,
finally end-of-program M17 and return to main
program.
Note:
SETINT instructions can be programmed within the
interrupt routine and used to activate additional
interrupt routines. They are triggered via the input.
You will find more information on how to create
subprograms in Chapter 2.
Save interrupt position, SAVE
The interrupt routine can be identified with SAVE in
the definition.
Example:
PROC LIFT_Z SAVE
N10…
N50 M17
At the end of the interrupt routine the modal G
functions are set to the value they had at the start of
the interrupt routine by means of the SAVE attribute.
The programmable zero offset and the basic offset
are reestablished in addition to the settable zero
offset (modal G function group 8). If the G function
group 15 (feed type) is changed, e.g. from G94 to
G95, the appropriate F value is also reestablished.
Machining can thus be resumed later at the point of
interruption.
