Inverters/phase converters

I am working on a project that requires a vector drive. The motor is rated at 5hp, as is the drive. This particular drive will not accept single phase input, so I have to have a three phase source for testing of the system. My three phase comes from a rotary converter.
Question: Will a good rotary phase converter work as a supply? I have been told that using any type of phase converter to drive a VFD is not a good idea. My reason for questioning this advice is that the individual did not know much about electricity in general.
I know the third leg voltage of my Arco rotary phase converter runs high when unloaded, but settles right down if it is driving a motor. Would I be safe if I ran a motor in the background to act as a regulator?
$645 is a good price for a vector drive, but it's not so insignificant that I can afford to keep extras around for when I make mistakes.
Any advice would be helpful.
