What part of Iowa? I'm just across the river at the NE corner.
Ed.
I used to run an SL-3 with Yasnac control. Had to load the programs from paper tape.
I’ll help if I can, but I’ve probably killed all the brain cells where that info was stored.
Those machines are real beasts that take no prisoners when things go wrong. Stay out of the line of fire of spinning work and chuck. Keep your hands out of the pinch zones everywhere. What does it have by way of a chuck? If it's a typical drawbar-actuated 3-jaw power chuck, it won't be real handy for onesy-twosy type work, as you'll need to be constantly resetting or reboring jaws to fit different work.
I never did but have something newer and similar with a Fanuc OT, pretty sure there is someone here who still has one
that is alive and kicking. First it is a Fanuc, that is great as they are the post popular, still supported with many repair houses specializing in older controls. Spare control parts are all over E-bay. The lathe is an 8 positioned barrel turret slant bed with a Fanuc controller, a very common combination. You will easily get help here even from people like me that never were in the same room as that model.
P.S. Even though my machine is a different make and a Fanuc OT the control panel looks very similar.
1st question to ask is do you have the manuals for the machine. You will find the Mori operators and programming manual very helpfull. You should also have a parameter listing for the machine as well as the Mori ladder diagram booklet and th emachine wiring diagrams. If you dont have these, look in the rear electrical panels to see if they are there. If not, and you have access to the previous owner, contact them and beg, borrow or steal any documentation they have. Without the ladder diagrams and parameter list, working on the machine is going to be difficult. You may be able to get the parameter list from Mori.
I've seen lots of Mori's from the late 80's resprayed to make them look like the 90's colors. I think a lot of shops did that to make it look like they had more modern machines. Certainly says something about Mori quality that all one had to do to make them cutting edge again was to change the color.
That's a real nice machine. 11T is a good control. It should do anything a new one can.
besides the paint, the only other deficiency I see is no chip conveyor.
It’s almost comical how well built these lathes are.
The “H” designation is for High Speed, IIRC you can wind it up to 4k. We had a SL4H and a TL5 from 1980. In comparison to the Hitachi and Ikegals of the day the spindle centre line is up higher, more ergonomic. Someone felt otherwise sticking it on those 3” rounds.
Any word on why the headstock cover is off it?
I actually have the chip converyor. Any chance you would have an avenue for getting a programing book? I'm striking out
Oh come on its not that bad!

BTW, a 20HP RPC is not big enough for that lathe. You might be able to run it in lower gears, but you need a 30-40 HP RPC to feed that lathe. It should have a 15/20HP spindle. You need twice the RPC motor to lathe motor ratio.

You don't need the programming book. It programs like any other lathe. You may want the Mori operators manual. That will tell you all about errors and alarms and maintenance stuff. The most important books are the wiring manuals and ladder. Without those you kinda have a paperweight. You can get all the Fanuc manuals for free as PDF's or you can buy them affordably on Ebay. I would suggest investing some time to track them down from the place you got the lathe from.

Check to see if there is a number on the face of the cabinet locks, I have extra keys, and they may all be the same. Do you have the key for the "edit" switch on the control?
I have a 15 HP homemade RPC that easily runs a 10 HP lathe spindle when I am leaning on it hard enough to knock a programmed 1600 RPM down to almost 1500 rpm. The load meter on that thing stopped working a long time ago. I haven't measured the draw in a heavy cut. It doesn't have gears, maybe that is the difference. It is very well balanced. On most cuts it is probably barely using 4 HP.
Agree on not needing a programming book, he just needs an M-code list.
I have owned and run almost the exact same SL2-H on an RPC. My RPC is comprised of two 30HP motors. My small mills (under 15HP spindles) will run fine on just a single 30HP idler. My 1985 20HP Okuma lathe will not run on 30HP. It needs the 2nd idler started. I just added a little live tooled Hardinge SP42 with a 10HP Fanuc spindle and a collet nose and I bet that will run just peachy on only one 30HP idler running.
And it's not steady state that's a problem with RPC's. The small problem is the current to accelerate the spindle, but the real big problem is the dynamic braking. RPC's will not push the braking enrgy back onto the grid through the generated leg well at all so you get an overvoltage condition on decel.
Sorry if you thought I didn't believe what you said, that was not the case. So what your saying is that model of machine has a higher than normal inrush current, than headstock spindles with similar horsepower.
