Re: VFD question

Unless I'm mistaken, you're mixing metifores.

The VFD itself generally is able to reverse the rotation and the
reversing starter is no longer needed. (The initial direction of
rotation can be sellected on three phase by reversing two of the
phase legs, but after that the VFD should be used).

If using a three phase VFD on single phase, with a three phase motor,
check with the manufacturer on sizing. Some can be used for their
rated hoursepower, some have to be de-rated by as much as 1/2. I am
told that it has to do with the size of capacitors the manufacturer
elected to use. At a given HP, a single phase hookup will draw more
current per phase than a three phase feed.
