Hello good Morning.
cnc okuma lr 15 osp5000L-G had already given this error.
but he would turn it off and on again and the error would disappear.
however today the machine on call appeared the error


1-1 CPU ALARM BUS ERROR (CYCLE OVER)
and did not disappear any more.


I've done some research on the internet but without great success ...
I do not understand much of these things ...


I leave here some photos
if anyone can help me !!!

Hello. I have the same problem. How did you solve it for yourself?

This is old thread, but I had similar problem before, and I had to change out MB1 and MB2 boards, then re-install all softwares and programs back into the controls....make sure to have backup...

Edit: would recommend contacting okuma dealer also to confirm, everyone's problem can be different. Sometimes it could be a completely different board according to Okuma dealer. We even swapped the backplane to see if that fixed a problem.
