Can anyone tell me if there is any likely problem with running a 415v 3-phase input VFD off the 415v output of my rotary phase converter?
Trying to come up with the best solution for my lathe, which is currently running (unsatisfactorily) a 415v 3ph motor off a 240v single-phase input, 240v 3ph output, VFD. Now that I have the 415v available via the transformer in the RPC, I'd like to feed it to the lathe. One option is to replace the 240v VFD with a 415v model and plug it straight into the RPC, the other option would be to restore all the lathe switchgear and wiring to the original 3-phase configuration and run it off the VFD that way. I'd much prefer the 415v VFD option but not sure if a VFD would be happy with the 'artificial' 3-phase.
