    Unhappy old okuma lc20

    we have a old early 1980`s LC20 with OSP5000L controler , the problem we are having is the x axis keeps tripping an alarm #4802E6 x-axis
    servo amp. sometimes resets straight away, other times need to reset 100`s of times untill alarm cleared. any help would be appreciated
    thank you

    check the x axis drive unit (it's the "servo amp"). Could be a problem with IGBT modules or maybe bad contact of connector only.
