    I our location, we still have many eddy current
    motor's in use.
    This morning, one of them had a minor motor short
    that worked it's way to the brake and caused some
    high voltage to leak back into the drive causing it to burn up!
    if the Motor was properly grounded, this would not have
    happened.. in any case, damage was done.

    Well, now the next story, we have no more Drives in house, nor
    do we have time to fix any... this was a HOT!!!!!!!! machine and
    had to be running!... So solution!!...
    and they all got a chuckle out of this one.
    used a KB regen drive to operate the clutch and brake along
    with feed back options..
    After a few hours of fast hacking work using a couple of
    DIODES to split the signal between the brake and clutch on the
    output with a load R on both sides, i had that baby running just
    as smooth as it ever did!..
    They were not chuckling at me afterwards!..

    It's a amazing what a little ingenuity will do for you, when
    you're in a jam!
     


  2. So, you either did, or had, a shoddy installation that was allowed to
    fail, then you do a half assed patch and want a pat on the back?
