    OKUMA SVP board: 1-1 CPU Alarm bus error

    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
    Experience is what you get just after you needed it.
