According to ATP* :

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?


Probably not -- but you can often fool it by strapping the one
unused phase to the nearest of the other two. It is not checking
whether it is different from both of the others, but rather whether
there is something there -- so it can safely shut down when being used
at full rating if one phase of the power feed is lost.

Enjoy,
DoN.
