Programming LU400 Simulturn

[Cmac]

I'm familar with programming single turret okuma lathes but need help getting the lower turret cutting. Dont have a post and our hardware key isnt unlocked for an LU. So barring those things how do you get the lower turret cutting. I know G14/13 are for upper and lower but i cant just plug both in and get it to work. Im running an OSP-P100 display. Any help is greatly appreciated.

You need the P codes as well, those are timing codes, so P1 on upper, with a P1 on lower would run at the same time. Also, G110/G111 for CSS on upper or lower turret, since you cant do both.

Cmac, here's a somewhat striped down prog from a LU400. we have controls from 5000 to p200 the programming's the same. fyi, we had trouble with nose comp when we turned it on in the same line with a P code, but that's easily avoided. G110 will give speed priority to A turret, while G111 gives it to B should you be making more passes or want maintain speed on your lower tooling. i've noticed alot of people mix the upper & lower progs together. i prefer to write 2 seperate progs. seems cleaner & easier to me, but a that's personal preference.
anyway, hope this sheds a little light. good luck!
oh, one more thing. you'll notice a P-5 mid way down. your P codes must ascend. so to repeat an earlier proccess, you can stick a neg. code in. kinda restarts the count. keep this in mind if you use sub-programs. when you return to the main prog, you'll need to proceed with higher numbers.

First thanks for the replies. Ok i understand writing a prog. for each turret but how do you select one for each? When i select a program it runs for both turrets regardless of what turret i have selected. Sorry for my incompentence please have patience.

if you're trying to run a turret indepently, you have turret selection buttons on the upper key panel, which it seem you've found, you also have turret interlock buttons on the lower key panel by opt stop & mid-auto. works like machine lock - hold the the interlock release button while you press the button for the turret you want. to return to both turrets, do the same thing. it will then release the turret you've interlocked. even if you've only programmed for one turret, you'll have to use these buttons. hope this helps, i apologize if i'm not understanding what you're trying to do.
