I have a kuka krc2 robot and a fronius welding machine. Did not make mistakes for a long time. But I'm getting an error that I don't understand and it's a strange error. The program runs smoothly on first run.There is 'loop-endloop' inside the program.The program loops for the 2nd time.Performs normal movement commands.The message 'INTERRUPTION 6 NOT DEFINED' appears when the ArcOn is at the beginning of the point.I get the program back to line 'INI'.Once you do this, the problem goes away.In short I always have to run the 'INI' line to run the program.But it should work once.
The error message I got is below.
