Program stack overflow

[tomasss]

Good day,

I use KUKA KRC1 with software V 3.2.6 SPO1

I create new Program structure

Haupt program (haupt981), Polishing program (P981_PM), Glanc program (g981_PM)
I run the robot on automatic cycle and whe the robot made 7 piece that signifies (7x passage all programs). The when the robot jump from (haupt981) to (P981_PM) robot arm will stops  on INI (Inicialization) and in the text window is Program stack overflow. But I dont know where is mistake
every time  jamming up 7 repetition

One of your programs, rather than ending properly, is calling the higher level program again.  You have something like this going on: 

Code:

DEF Program1()
  Program2()
END
DEF PROGRAM 2()
  Program3()
END
DEF PROGRAM3()
  Program1() ; DO NOT DO THIS!!!!  Simply let the program run to the END statement and the pointer will return to Program2 naturally.
END

Except under very specific conditions, a program should never call itself, or the program that called it, or the program that called the program that called it.  What's happening in the example above is that Program3 never ends, but instead calls a new second instance of Program1, which calls a new second instance of Program2, and so on.  The KRC controller can do this, but only up to a limited point -- the stack can only hold so many programs.  When you call one program too many, the error occurs.

Without seeing your code, I can't tell you where your bug is, but it's definitely something like this.

I had wrong program-structure. I solved this problem, thank you for your advice.
