Okuma LH35 OSP2200

[Ray Nielsen]

Hello, I am new to all this, so hopefully won't make a fool of myself. My trade is auto machinist and have had all my experience (40 years) on manual machines. I have always wanted to get into CNC , so recently I purchased an Okuma LH35 with OSP2200 controller. I was advised to be very careful because the controller and all its components are obsolete. The machine itself is in excellent codition and for what I paid and the type of work I intend to do it was certainly worth the risk. It was working fine when it was demonstrated to me and when it was relocated into my factory.
I have spent some time cleaning it all up, painting etc and now I cannot input any data. Everything still works fine on the output ie can manually operate it, use the block function and run the program that is still stored. Just can't input anything like zero and tool off sets, speeds etc.
I know its a big ask, but can anyone give me any advice on where to go.
Regards Ray

Have you got the "Edit" lockouts enabled ?

the keyed switches ( on front of the control ) that stop un-authorised changes to running programs
- these are mainly used for a production type environment, or larger shops

Thank you. My control panel doesn't have any key switches , but I guess the switches with the idiot covers on them could be the same thing. I will have a closer look at them .

is the machine/control anything like LS-N 'Big 10'? Like this one....

If yes I have the manual here (in storage for 20+ years ;-)
From memory there is no RS232 interface, you have to load the program via a paper tape. so you would need a tape punching machine or teletype with tape attachment.
I operated that when I was an apprentice in 1986 and when the company went broke and sold off everything I grabbed the manual as a souvenir :-D
It has (or had) OSP2200 control so yours should be similar.

Looking back now it was very simple compared to current CNCs but at the time I didn't really know much and I read the manual from cover to cover multiple times and it helped a lot, although back then I was only running programs that were already written, and making simple changes not writing any programs from scratch. The usage of it is very different from current machines though. anyone who knows the latest stuff wouldn't know where to start with that old clunker
