Automatic interrupt pointer
In certain applications it can be useful to automatically define a prespecified type of coupling as a search-
suppressed area. The automatic interrupt pointer function is activated with machine data
MD 22680 $MC_AUTO_IPTR_LOCK.
• Bit 0 = 1: Electronic gearbox with EGON
• Bit 1 = 1: Axial leading value coupling with LEADON
This program section begins with the last executable block before the activation and ends with the deactivation.
The automatic interrupt pointer is not active for couplings that were activated or deactivated via synchronized
actions.
Example: To declare axial master value coupling as search-suppressed:
A program abort within search-suppressed program section (N200 - N500) always provides the interrupt pointer
with N100.
Table 9-4
N100 G0 X100 ;
N200 EGON(Y, "NOC", X, 1,
1)
; search-suppressed program section starts
N300 LEADON(A, B, 1) ;
... ;
N400 EGOFS(Y) ;
... ;
N500 LEADOF(A, B) ; search-suppressed program section ends
N600 G0 X200 ;
CAUTION
Using an overlap of the "programmable interrupt pointer" and
"automatic interrupt pointer" via machine data, the NC selects the largest possible search-
suppressed area.
A program may need a coupling for almost all of the runtime. In this case, the automatic
interrupt pointer would always point to the start of the program and the SERUPRO function
would in fact be useless.
