LOL sucked in Steve... I also had a couple of LC30's with OSP3000 controllers, been a damn long time since had anything to do with them tho... been wracking the brain thinking if I could help, but so far nada.

no joke. Client ordered training for this Okuma (LC20 OSP3000).
Control hangs up right after 10 minutes of "training"
Your advices are very welcome.
"Reset" is only button, which seems to work.The "tape" indicator blinks while "reset" is pressed.
No reaction to other buttons at all.

What cycle or function are you doing when it 'hangs'?

Most likely a flakey limit switch.

Were you doing a tool change?
Were you clamping / unclamping.
Moving tailstock?
Axis very close to limit? (not very likely)
Barfeeder operation. (if you have one)
Software chuck boundary limits?
Oiler not working or out of oil.
Door switch?
Low hydraulic pressure?
Intermittent foot switch.
Faulty tape reader. You can unplug multiwire cable at the tape reader and machine will still function.

ANYTHING with limit switch contacts.

When some operation that moves something operates a limit switch, if the switch is supposed to change, the machine will wait until it changes, or in some cases time out because the switch never changed as expected.

Check all of the above, and see if certain operations lead up to the fault.
