I need to adjust the barrier parameter on a T2 lathe control. Anyone know which one it is?

I assume you are looking on the Barrier page (5/7) ?
I have never changed these, and do not have what each represents, but I guess in the absence of any further info. you could experiment by changing the first obvious ones like
BAR: OUT
:IiN
:FCE
AL.

I found it in the manual (One of 15 I got with the lathe). Took a bit to dig it up.

There is a soft key in that menu in the T2 for barrier teach, each tool has a chuck and tail stock barrier you can set.

Hi,on a fanuc 21i-tb lathe the barrier menu is not open.How can i activate it?What is the paramater of it and which byte should i change.
Thank you
