It sounds to me like you are running on, or beyond, the limits of derating.
Single phase to 575v with transformer and VFD update
Jun 24, 2005

I wired up the single phase 240-600v 1750VA transformer to my used AC TECH 2 hp VFD (with three phase 600V input)to power my 1 Hp Bridgeport this morning. It works, though it causes a lot of radio inteference. I only ran it for a few minutes and not under load so I don't know if the transformer will heat up to much.
Before I do more testing I am going to build a metal enclosure for the transformer and possibly build in a cooling fan.

Stan..something to keep in mind when running a VFD.
AM radio no longer exists in your shop for the most part.
