Hello!

Once again I'm coming to the CNC zone to help me solve an issue. I'm using a Fanuc 35i control.

I have a creep-feed grinder that is encountering a spindle overload. I didn't write the program but I'm stuck fixing it. When the overload happens, a macro executes. This macro retracts the spindle to a safe location then does a soft-reset. When this happens, the program rewinds to the beginning, losing the place in the program where the fault occurs.

My question is this: Does the control store the currently executing line number (N-number) in a parameter than can be extracted? My program has N-numbers on every line.

If it does, I can modify the macro that retracts the spindle and rewinds the program to grab the current line number and put it in a variable before rewinding, letting me know exactly where the fault occurs.

Thanks for reading...

#4114 rings a bell. I use this variable to return to main program at a specific line number. #4314 may be more suitable though. I think 4114 is last N in buffer and 4314 is last N executed.

DP,

Thank you so much for your reply. #4114 does the trick. Exactly what I was looking for....
