If the previous owner was using a RPC and it was running fine, I'd have to agree with the others who posted--- that it's the VFD that is the issue.
I've never had a VFD so I can't comment on how "great" they are. Only thing is, I am a fan of rotary phase converters; a properly sized RPC will run any 3-phase motor that you currently own or may purchase in the future. No programing, Yada, Yada, Yada, you get the picture
