Oh...I failed to mention that running a VFD on SINGLE PHASE may indeed decrease the HP rating, depending on the particular drive.

I think I found the problem. I believe one of the wires for the output (3 phase) didn't connect very well to the VFD. I had taken off the motor and checked the wiring. It was wired for 220 vac (vice 440). While I had the wiring loose I tinned the end of the wiring to make it easier to insert into the terminals. I put everything back together and WOW! I can take cuts now I couldn't dream of before. The adjustable speed is fantastic, and the deceleration rate (adjustable) is excellent (I have it set for .4 seconds). I only need to hook up the remote pot to complete the installation.
I faced some 1.5" crs with an indexable carbide tool at about 1.5 times the speed I used to do it at (due to the capabilities of the lathe at the time) and what a much nicer finish. It's going to be like learning to use the lathe all over again....
