Motor not spinning and then drive error (fault 4)


As the title says, I'm getting a Fault 4 error.  The motor brushes are good and the relay is acuating when I press Start, but it's just not turning.  Is there a way to isolate the motor and just run it from a 208 outlet?  That would elimate the possibility of it being bad.  I tested the windings and they seem okay as far as I can tell (not open and not shorted to ground).  Any info would be great!
