Hello,

Guys, can you help me, please?

We have a machine OKUMA LAW-2S 2ST OSP7000L...

Okuma write message:

1-2 CPU ALARM BUS ERROR (SYSTEM BUS PARITY) SSW=0115 ACCESS ADDRESS=001E4664

We try change board from other machine like it, and when we change SVP BOARD 1911-2160 OKUMA works ok!

We buy new board 1911-2160 (E4809-045-158-C), but OKUMA write:

1-1 CPU ALARM BUS ERROR (SYSTEM BUS) SSW=0145 ACCESS ADDRESS=FC080000

We think board new, but it is not working...

Boards very expensive, may be who know what we can do it?
May be need initialization board?
