Lns Bar feeder

I want to know if someone can tell me how to program a Lns bar feeder on a lathe with control Fanuc 18-t. Right now I'm missing the pages of my lathe's book that talk about the bar feeder programming codes. All I can do is stop the spindle, open the chuck, make the bar feeder push the bar and there nothing more (it keeps pushing). Would be great to have a program exemple.

Thank you

is it a hydrobar or magazine? if its a hydrobar then it is normal for the unit to just push, you have to position the turret with a bar stop to control the bar length. with a magazine it is more complicated.
