    Default Yaskawa servopack replaced - tune/adjust?

    My machine (Matsuura MC-510V) came to me with a frozen y axis ballscrew, which had also taken out the y axis servo pack. I repaired the screw and picked up a used servopack (cacr-sr15sb1af), and installed it.

    Machine came back to life and everything seems fine unless I jog the y-axis (only done this manually as I am still learning to program) at 100%. When I try to jog it at 100%, the axis jogs for a split second, and the the servos shut off, with a 310 servo off alarm. There are no errors listed on the packs. X and Z axis are fine. I made no adjustments to the new new (used) servo pack when I received and installed it. Should I?

    I'll admit, I have not gone through the Yaskawa online manuals to see if should be 'tuned' - I can/will, but they are often pretty cryptic and thick. If there's a 'field' procedure to adjust a few pots, that would be preferable, and would probably be good to have posted on the web for others..

    Also - is there a good US source for Mitsubishi IC's (power mosfets) for repair of these packs? I got some shipped from singapore when I tried to repair the dead pack, but shipping was really expensive.

    Thanks in advance,

    Brent
