    York YTK VSD fault

    working on a york yt, vsd,phase c, over current trip (@24 amps) book says if fault continues an output pole is most likely the culprit. Question is what are they calling an output pole, is it a gate driver board

    If you don't know the difference between the two, I suggest that you employ the assistance of someone who does. The mistakes made on this type eqpt have lots of numbers to the left of the decimal point on the check that pays for them, and at worst can get folks seriously injured. Besides, this isn't an open forum question.

    KLOVE's point too:

    ...These
    basic instructions, though time-consuming, cover
    fusing, wiring and motor lead length and provide a
    great deal of reduction in failure of the drive system
    [4].
    With the change to asset management, predictive
    maintenance conferences are focusing on managerial
    education and the tactical steps required in following
    through with this approach [3,5,6]. This
    management shift from cutting expenses to
    increasing efficiency is changing the maintenance
    professional’s perspective from a “replace the
    broken” to a more proactive root cause analysis that
    identifies problems prior to failure. Leading
    manufacturers have identified that electrical
    component replacement (motors and drives) is the
    third highest operational expense, behind wages and
    energy. Hence, they are investing in training and
    equipment to attach the problem.
    The drive exposes the motor to millions of impulses,
    thus requiring effective maintenance and installation
    of both the motor and drive [7]. Line and load
    reactors, line traps and MOV Surge Arrestors [8] are
    protective devices that are needed even though their
    payback is not immediately apparent. ~~~~ WOW!
