Make sure the VFD of choice will run on single-phase. Some have phase
loss
detection which shuts down the unit if a phase goes down.

Is that a parameter that can be changed through programming?

It's a pretty unusual feature on small (10-20HP?) VFDs. In
20+ years of building and working around industrial
machinery I've never actually run across a small VFD that
wouldn't run on single phase.

Ned,
Why are small of the smaller VFDs rated for single phase? I do know that the
used VFDs that are rated for single phase seem to be going for a premium.
Are you saying that any smaller VFD will convert single phase to 3?
