    vfd programming is a fairly tall order. many vfd's have similar features, however, not all features are listed or available for programming. the features (and their programmability) are listed in the IOM of the vfd. as for troubleshooting, i have found the IOM to be pretty helpful in almost all cases. just look up the fault code and it will tell you what the vfd thinks the problem is...please keep in mind, that what the vfd thinks the problem is, isn't always what the real problem is.
    "Right" is not the same as "Wise".

    Don't step on my favorite part of the Constitution just to point out your favorite part.

    It varies greatly with the VFD manufacturer. The parameters are endless on most VFD's, you can order a VFD that is defaulted to a certain application like pump or air handler.
