Hi

I bought a very old lathe. I'm trying to restore it to former glory and trying to get it into working shape. I am a IT specialist, so not much experience on lathes etc.

I do not have any diagrams of this lathe, nor any manuals. I've been searching and trying to find information (even pic's of working ones) and have not been succesfull.

I did decide that I won't use the tape reader and have bought a BTR.

I have a huge pile of cable, a hydraulic motor, cooling pump and the original "brain" box and the lathe.

I connected 380V 3 phase, and powered up, the hydraulics, nor cooling pump are connected. The console's lights came up. It said Out of tape or something similar. According to the guy who sold me the lathe, all the motors were tested and working.

Now this is to where I can take it.

Is there anybody that can help me. I can post pictures etc.

I will run this lathe on MasterCam XR2.

I will greatly appreciate, I've tried getting manuals, but at an average of $300 each, they're out my reach.

Thanx alot.

What control is on it? some Okuma's were fitted with Fanuc 6T. If it has Fanuc, do you have the parameters etc?
Al.

When the time comes, I can help with OSP-2200 programming.

I'm actually not sure. What I could get on the Net is that apparently Okuma started using Fanuc controllers a few models later.

I've looked on all the boards, which seem to be VME to find any information, to no avail. I also sent a ton of mail to Okuma/Fanuc to see if they can give my any info. The only thing I could get a name on is that it has a Sanyo Denki Tape Reader. The servo motors are Yaskawa.

Where can I look to see if it is Fanuc? I greatly appreciate your trouble. I'll take some photographs tommorrow and post them. If it can help....

Thanx a million

Here is a list of machine alarms that might help get you through the start up: http://www.homestead.com/mtsspecialservices/2200L_Alarm_List.pdf

Good Luck,

i am so glade that i finally find something usefull on the internet that can help me to fix my problem.
it's been a long time since i buy my okuma lsn-10 osp-2200 lathe but almost 6 years i can't get this thing started :(
i buy this as a undamaged and in a good condition mashine that has work in a workshop in switzerland,but from the first start i know that something was not ok.
many peopels and professionals try to fix the problem but nothing happend
1 year after my father and i buy this mashine we make a decision to call switzerland and tell about the problem and we came to the final decision to bespeak the binary and the program tape from japan.
and anybody now what happends next :P
the tapes dont fix the problem :(
after that,we send the tape reader to switzerland and the say that the tape reader are intact.
we also try to program the osp2200 with the klik klak switches on the front table of the osp2200 and nothing happends
we also detect that the tape do not stop on the position he should and he wont stop until i press reset.
now i find mastercam x2 and predator dnc on the internet and i am not sure that this programs can fix my problem-i also have a rs-422 connector on the osp2200
i almost forget-on the main display are no error codes just sevens and nines on all lamps and they dont changes all 6 years :)
i have the complet user guide of this mashine and we try everything step by step but nothing
soo if anybody can halp me to fix my problem then please write in this treath and i will be the happiest man on the world:) really
PS-sorry for my english,i try my best:rainfro:

have really nobody an answer for my question-please post if somebody can help me
thanx ;)

I have an okuma LS-N Big 10 sitting in sotage if you need a parts machine. Located in pennsylvania. Please get this thing out of here. LOL

hehe jagermeister you are really funny :)
look at my profile and you will see were i live LOL
no really-in what a condition are your lsn-10 and have you the osp2200???
thanx

The machine was in running condidtion when pulled from service. everything worked. It had a Mark Century 550 control.

and why you wont to get your machine out of your sotage???
my lsn-10 is ok (i think so) what i need is a specialist who knows exactly what's wrong with my osp2200 or an elektrical shema
but thank you jagermeister for your offer

I have just printed this post out, i will have my OKUMA rep to have a look at it. then i'll let you know.

ok thank you rhino
if they are any indistinct in my post then let me now and i wil write exactly and step by step everything that im try

anything new about my okuma???

Well

I'm a little bit further. My machine powers up. The spindle is turning, the chuck is opening and closing, the turret turns correctly. The servo's are intact.

But I devoled a new problem. When ever I want to jog the axes, the Z axes just jump quickly from left to right (like it's loking for a position, which can't be found) and then stops and flash a Error 3, according to the alarm list provided in an earlier post it is a parity problem or the limits are outside of the feedback device. I've spoken to the Okuma agents in South Africa (not really anxious to help). Anyway, I swopped the encoders, as well as the drives. But exactly the same thing happen. When I disconnect the encoder, the servo runs extremely smooth until it hits the limit switch

I need to check some more, but at this stage I feel like it is the positioning card that is buggered, do you guys reckon the same, or might it be something else?

I can't get nothing registered on the keypads either, but one "expert" said I first need to get the axes right before anything else will happen.

I just feel that I'm quite close to actually cutting.

As always, all help is dearly appreciated.

If i remember right does this model of okuma use absolute encoders?
If yes, the encoders must show value inside machine work envelope when machine power is turned on.
Some old okuma lathes I have seen have machine origin position about 1,5m outside from machine! so you can not position machine axis physicaly in machine origo, the encoder position must be in right value straight from start up.

Regards Mika

Hi

Yes, they do have absolute encoders.

I finally got one Okuma engineer to talk to me on the phone for about 3 minutes. He thinks that the problem does not lie with the encoding or machine position, but with the tacho. Now I've actually took off the tacho, damn there can't be much wrong with it, it has a copper disc (tracked) and 5 magnets. Brushes seems OK, so now I'll start tracing and see if I get any voltage on the Tacho and its wires.

I must be honest I'm getting a little discouraged now. I'm so close, and now I sit with a machine which jumps on one axes. Everything else is now fine and working. Oh, that was a little lie, my front turrent is spitting out H fluid, think I burst a pipe the other night.

By the way, when my z axes jumps around, it actually is encoding / recording the position. I measured the distance from where I turned it to 0 and it actually is spot on!

I really need to get tjis now up and running. Got a PMAC (Delta Tau) ready for a transplant, but then I'll have to get rid of the encoders, and they seem so damn nice.

Anyway will keep posting.

ANd again thanks for the help.

Yopower, pm me, I found some electrical diagrams, which I can scan and send to you if you still need them.

Regards & keep well

What is the head bore on this machine?

hmm were can i read this-head bore???

hole through the spindle

you can place nothing true the spindle
there is no hole
the spindle is hidraulic

hello everyone,im still not further with my machine,i have done some tests with the osp 2200,the voltage an the cpu voltage are now in proper range.the binary tape stops at the last holes but the no1 control tape just want to stop stop at the last holes.
what i explore on the main switch board is that 2 leds dont work properly one light al the time and one newer,but when i place the memory switch in the up position then they work.but with the PC switch in up position-on then they dont work.i am 99% sure that a circuit board are bad.have anybody any idea???
i newer come to this conclusion without help from a friend from america and i thank him so much

Hello everybody

i have to update this treath with my newest results

i find some used pcb boards in finland and buy the
memory module (16K)
mother board
3D Board
Switch board and pcb board behind the switch panel

After i plug in the new boards i first try the flickering method (that dont work with my original boards)and try to feed the memory with the control tape NO1
The tape dont stop at the last transport holes so i try bootstraping the machine and load the binary tape.everything work just fine to the binary tape.and then when i try to load the control tape NO1,the tape dont stop at the end and just runs trough,i try everything about 50 times but i ever get the same results.
i think that there could be a problem with the 1F2C pcb Board that controls the work of the tape reader.but if so,why the biary tape stop at the correct place and the other tapes not.i also receive the tapes of the new memory module.
have anybode an idea what could be the problem here?????
i would really appreciate any kind of answer.
Thanks guys:D

Ok guys i got finally this machine started:rainfro:
sorry mods for updating this thread again but i just want to help some people (if there are still someone like me that uses osp2200) who maybe have the same problems so i can help them,cause the machines are really rare but reliable and still good working after 30 years.
i manage to fix my problems but i had to change all of the pc boards in my osp 2200.
after that everything went good and now i have a fully funktional machine:)
so if anybody have a problem with a osp2200 i would really like to help them
dont hesitate to contact me at

yupower1@hotmail.com
or
boracompany@gmail.com

Regards to everybody who read this thread

Respect to the CNCZone Forum

just keep on to do such a nice job

hey guys , anyone know the motor and controller specs on the LS-N ?

horsepower , maximum speed , and controller type , ie MOSFET , IGBT , inverter or star delta etc ???

hi
i have all manuals,do you maybe know if there are this specs writen,so i can look and scan you this pages
regards
Bora

hello

i dont know what page they are on

i am looking at if i can use the motor and controller in an electric vehicle

the horsepower for the motor should be there at least

is there a page for specifications or power consumption ?

any detail or pictures to connect to the motor controller ?


thankyou if you can help

Hello Friend
is me again with my old okuma :))))))))))))

my machine is running but i have still problems to use all of his options and i can only use G0 G1 G2 G3 and one tool

i will write again my problems and what kind of work iv'e don't on the machine



It's a long time ago since we bought the machine unfortunately in a bad condition.first we did,we order original tapes from okuma switzerland a tried every option to load the binary,#1 and #2 tape but with no success,only the binary loadet but the two others never.

After that i made contact to a man in USA and first of all we checked the voltages and everything else that have to be check't on the machine and we came to a conclusion that the memory board is death 100%

Then i found a man in finland who had 2 of the okumas and he was willing to send the memory,mother,switch and #3 board to serbia for a really fair price.

the boards arrive'd and i imediatelly change my old boards with the new ones.
unfortunately no luck.

i ordered the other 8 bards from finland and so i changed all pc boards on my okuma

bootstrap good
binary tape good
control tape #1 good
control tape #2 good

i power up the machine and i saw the first time only zeros on the display :)))))


after that i had to learn how to use and to program that machine and so i discover that some options are not working.

MDI don't work at all

tool offset also

after loading anykind of program to the memory its impossible to edit the program in the memory -error 79

lap programing also don't work,the machine don't shows any king of errors but shes not doing what she should.

Things that work

tool changer

changing spindel speeds,but only with help of a tape because the mdi dont respond

zero set

working with simple programs and one tool


ok that preatty much all

a big thing that i have to say is that it could be a hardware/software problem
i notice that the machine originaly only have 2 decimals (one nixie tube place on the pc board is empty) and by the original books you have to write programs with 2 decimals

i did that the first time i wrote a small program and run straight in the workpiece :)))))))
fortunately nothing bad happend so i discovered that i have to write programs with 3 decimals.

i also notice that the direct tool offset buttoms are empty by default and maybe my new boards have the options to DTO,there are cables behind the control panel right behind the holes where the DTO buttoms should be.

I think that are enough informations for some specialist and i really hope that someone can help me to fix my problem,i would really appreciate that.

PS:here are some pictures
I will also upload some pictures of the tapes that i have

Regards to all

Bora

Hi,

If you cannot input data from keypad then please check the jumper on Slot IF2 and make sure that K-B is jumpered. This will then enable the keypad. Make sure that the connection next to K-B( on the left ) is cut.

Hi,

I have just noticed the Tapes on your Photos.
Make sure that you only load the correct Tapes for that machine.
Control Tape No.2 is your "Options" Tape. There will only be one of these and not very long. If you have load the incorrect Tapes then you would be lucky to have anything running correctly.
Again, please check that you load the Tapes for that Machine.

Hello Sertec

Thanks for your reply,i check almost everyday this thread for new reply's and anykind of help makes a smile on my face :rainfro:

i pulled out the if2 board and it looks like that K-B is jumpet and jumber next to K-B is cut,but i have also notice that there is no option to change this because this is so made by stock,you understand what i try to say,there are no jumpers like on new computer's,i will also make a few pictures later this day.
I also notice that (K) on the back side is connected to the other jumper but i think that this is normal because this are dubble side printed boards.

About the tapes, i think that there are loadet correctly,#2 tape is almsot 3 times shorter then #1 tape
but there are also big differences between my original tapes and and tapes i bougth with my new boards.i will also make some pictures to clear what im talking about

Regards
Bora

Is your Machine #1144?
If not then please use Original Tapes.
In fact I would use the Original Tapes first.
The Tapes that you bought with the other boards sound like they come from another machine. Don't use them.
Normally if Control Software Loads up ok and the computer runs, and there are still programming issues or machine is not running correctly, could mean that there is a problem with your tapes.
If there were any faults in Slot3~6 then machine would not run or in most cases you would not be able to load Control Software.
IF1 will affect the Panel and some Display functions. - could be a problem
IF2 will affect MDI Input and Tape Reader. - should be ok
IF3 is only Input / Output. - Possible problem but I think Unlikey as you have too many problems for this to be causing them all.
IF4 is ok as you can move axes around.
Are you running CMOS Memory( 16K ) or Core Memory( 2 x 8K )?
If CMOS( 16K ), has Slot 3C been changed to 3D and Modification to Motherboard been done?

Lots to check but we need to start form the beginning now to make sure all is correct.

Cheers

Hi sertec

First of all here are the pictures
right are the tapes i ordered from japan a few years ago and left are they i bought with the new boards

the other two pictures shows the jumpers on the board on front and backside on the IF2

i think this is clear now

http://i264.photobucket.com/albums/ii197/Yupower/Image0099.jpg





ok now to your questions

i have a 16K memory board but im not exactly sure if it is CMOS or core memory but i have all pictures of my new boards and i will upload them later this day.

i also have to say that i changed everyone of my boards including the motherboard and the switch board so i dont think that i have to make some changes on the motherboard.
i also have the 3D board next of the memory board where you can select the sice of the memory board and this is also ok

regards

Bora

ok its me again with some new pictures
i hope that this thread will also help other people who have problems with this machine:)

@sertec
here are all my pictures from my new boards

i have to notice that my old board are tan color so this are newer generation boards and i thank that everysingle one of them are in a good condition.

you told me that i should try to load my old tapes and today i think about that and i know that a few months ago nothing happend because the tapes dont stop on the last transport holes where it should stop if the tapes are properly loadet.

there is also a problem with the control tape #2 from my new boards because the tape was in such a bad condition that i had to fix the tape before i load it the first time in the memory
here are a few pictures

i fixed the whole tape and it run trough the tapereader and stop at the end,i think that is a clear sign that the tape is ok now,or maybe not???????
i really dont know i just want to run this machine

regards

Thanks for the Photo's. Jut one thing, can you punch holes where you have used cellotape. Sometimes the Tape Reader will not read thru the cellotape.

i tought about that and i can do that with a soldering gun
i will try this next
do you have any other clues that i could try
thanks for your reply

You are using Core Memory.
Can we go thru the steps again of how you have loaded the Control Tapes.
1. Start by using the switches as per instructions in manual
2. Then load binary Loader
3. Load Control Tape No. 1
4. Set Switches
5. Load Control Tape No.2
6. Power Off.
7. Power On.

do you get this far?

i done all this correct with the tapes of the new boards

the original tapes didn't stop at the end and run straight trough the reader so i went to the new tapes and get this far

ok thats good.

Make sure of the following:

can you set your zero offsets?
can you set tool offsets?
can you edit program?
can you select speeds by MDI( is your machine 12 or 24 speed )?
can you select Tools( what config is your machine( V6 + H4 etc )?

if you can do all of the following then i would say you have a runner.

can you set your zero offsets? ------Yes
can you set tool offsets? ----------- No
can you edit program? -------------- No

can you select speeds by MDI( is your machine 12 or 24 speed )?
------i have 12 speeds and changing speed with the MDI dont work but it changes speeds when i load a program


can you select Tools( what config is your machine( V6 + H4 etc )?
------tool changing works good,it also work when i load a program
but i cannot change tools with the MDI

yes it is a V6 + H4

You say you can set zero offset. ( Front and Rear Turrets )

Can You Type any Number when setting Zero Offset

eg 1234.56 WRITE

then press Slide hold to Calc Position

Please explain how you ran a program

Hello Sertec
here is a link to rapidshare where i upload 2 videoclips,the quality on youtube is to bad so i decide to upload the original one's

http://rapidshare.de/files/47141737/Desktop.rar.html

you can see clearly there that zeroset works good but i can't write anything on the MDI

on the other clip you see a short program with a radius.
before i run any programm i first set the zero on the back of the workpiece by Z
and in the middle by X

i do that with every tool and i write seperate programs for each tool cause as you see tool offset and mdi dont work at all.

i hope that my problem is much clear now

thanks for your help

Ok thanks for the Vids.

Your problem has got to be IF2 - This is the board which controls all MDI Function.
Even when you set your Zero Offset it looks like you cannot enter Data.
So either problem is in IF2 or The Data Keypad.
Can you double check to make sure that K-B is connected and the connection on the left of K-B is cut ( disconnected ).
Please use multimeter to check.

i will check this tomorrow it is late now
thanks for that information

Also if all looks ok then check the wiring from Data Keypad to IF2.
Check connectors at IF2 and make sure all pins have pushed in.
Sometimes the pins will push out or have come loose.

hi sertec

i check everything you say

connectors are in a preatty good condition,cables are also good,the osp2200 case look very healty,there is really no sign that a cable could be snap'ed somewhere.
i also open the data keypad and there are also no sign's that anything bad happend.the pc board behing the mdi where the 10 digit's are is also good.

i will today try to load again the control tapse,but first i will clear the holes and get rid of the cellotape so the reader can easy read the data.

regards
Bora

Hello Sertec

here are the results from my todays research

first of all i cleaned the cellotape from the holes and i read the tapes with the flickering method.
everything went good but i have again the same results,no MDI,no tooloffset function.

then i went to my original tapes,i load them also with the flickering method and both tapes stop at the last transport holes.i restart the panel but the controls dont came up,nothing works,and the digit's show some wierd numbers.

after that i load again the tapes i bougth with my new boards and now im back again where i was :)))))))


i just want to say that i still have my old boards.
a few months ago i tryed to replace the IF2 board with my original IF2 board (thinking that maybe this board is not compatible with my display),as i power up the machine,the Z axis begone to jump violently back and forth and i immediately shut down the system.i install again the new board and everything was ok again,maybe this information gives you a clue?????

i really dont know what to do next :(((((
it looks hopeless.

do maybe someone know how i can contact okuma directly do get some informations?????

thanks to all
regards
Bora

I still believe the problem is the IF2 Board.
Are you able to get another IF2 Board?

hmmm i dont think so because this boards are pulled out from a working machhine-that is what the seller told me i dont think he is lying.

unfortunately he sold all of the remaining parts he had and i dont think that i can find some boards again.
the IF2 board dont look much complex,is it hard to find any damage or bad integrated circuit????
i could maybe use some parts from my old boards if i manage to find any damage,but i have to send them to a professional to check them i dont think that i can do that.

Can you contact me on sertec@surfer.co.nz
I have complete sets of OSP2200 PCB's

cheers

Peter

i installed scype right now
