Hi!
I have a question regarding R-parameters.

I’ve managed to write a programme that uses the integrated bar loader. I come across the R-parameters 741 and 751. The only information the manual provides is “signal out of material” and “flag out of material”.

What sensor or device sets this to 1?
After each finished part in my program, I check the parameter r741 and if it’s 1, I eject the unused stock and position the new bar.
I cannot get the sensing of bar end (r741) to work, and my stock eject never triggers.

Does anyone here have any insight?

Thanks!
