OKUMA SVP board: 1-1 CPU Alarm bus error

[robodo]

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?

I think problems with optocoupler "okuma FLC1-B" (okuma FLCI-B)... who know where I can buy it? or may be equivalent part?

Try fiber-optic cable first. It is not uncommon for them to crack and cause faulty communication
