Barfeeder programming

[sitti]

Dear All,

I have problems with programming Miyano BNC 34C5 lathe machine (Fanuc controller) with an LNS Quick Load Servo III barfeeder.
Could somebody send me an example, what is the exact way to control the loading of the new bar?
If the bar is in the lathe machine, then it is no problem, I can feed the part length. But when the barfeeder reaches the end of bar position, the lathe should jump to a sub-program, which is for the bar loading. But I have no idea how to check in the part program, if there is end of bar or not. On Mori Seiki machines I know, that it is with /2....
Any idea?
Thank you in advance,
Adam

If this is a Fanuc control you caould use some Macro B logic to count the number of bars cut and then jump to the sub program one you reach a specific number.
