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.
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.
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.
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.
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?????
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.
Dump the OSP2200 and do an upgrade. Most parts are not available any longer, almost no service guys alive any longer to fix it, and no CRT or memory. Last one I even looked at was ten years ago, and I think the repair bill at that time was 6K. 4K just being 2 boards.
