MAZAK SmoothC - Setting a Tool Load Limit?

Hello! I am trying to program a MAZAK QT-C 200M Lathe, MAZATROL SMOOTHC.

My question is if I can limit how much effort the tool makes. For example, if you pass a certain % of effort, the machine stops, or if the machine performs a certain operation and the effort is equal to zero, I know that the tool broke and also stop the operation.

For this programming it has to be EIA/ISO. I need examples because I found the M Codes but I couldn't understand how to fit in the program, if anyone has this knowledge please help me!!!! Thanks!

Does anyone know where I'm going wrong?

The format looks correct, did you actually try this on your machine or is this just sample code you were given? Overload detection is software option #47 "2nd Aux Functions", it would not be standard on your lathe. Also it will only detect an overload condition, not an underload if a small tool broke. You can monitor any combination of the axes and spindles.
 
I tested this program on my lathe and a linear tracking error appears, probably because I don't have this option on the machine, I hope I can add it, as this will improve the process a lot.
But that was it, I thought that the way I did the program could be wrong.
Thank you, it helped me a lot, if you have anything else about this type of programming, please pass it on, because I couldn't find anything on the internet, thank you very much!!
 
There is a whole separate manual for the function that you should get when you purchase it, that has samples of program format and an explanation of what the different M codes are doing. It looks more complicated than it is to use.
