    Exclamation OKUMA MC4VA OSP5000

    Hello,
    I have OKUMA MC4-VA with OSP5000 control and YASKAWA VARISPEED 626MT2B drive.
    From couple of days I have a big problem:

    when I tried to stop spindle it does not stop but slow down and rotate all the time 20-70rpm but not stable
    MDI and RESET, STOP or ORIENTATION buttons does not work, Only way to stop spindle is turn controll off..

    I have no idea where is the problem, can someone help me?
    Thank you

    congratulations / you finally achieved 100% spindle time

    many shops have to work really hard to reach at least 70%, but voila, you did it like a charm

    is easy to reach the top, but can you stay there ?



    sorry defcom, i have no clue
