Hi All,

I am planning the rebuild of a Hardinge HLV-H and as I only have a single phase supply was going to configure the power electrics in a similar way to that described by Bill Todd. The problem I am facing is identifying a suitable VFD as all the one's I have reviewed so far have a Low Voltage fault code for when a phase is lost. This would therefore cause a fault if I connect a single phase supply to the 3 phase VFD as one phase would be missing. Please correct me if my understanding here is incorrect. I have contacted a number of VFD suppliers and they are telling me that this configuration would not work. Can anyone advise me of a manufacturer that produces VFDs that I could use or have VFDs evolved so this can no longer be done?

I would very much appreciate your kind advise.

Cheers,
Dave
