i acquired an old Lagun 250 cnc mill. Everything worked when it was setup with its previous owner. It has a 230V 3 phase plug. I don't have 3phase in my shop so i ran a 220V single phase cable to the mill and i bought a single to three phase VFD. I originally assumed i could just wire a receptacle to the output of the vfd and plug the mill in but after looking at the VFD manual it mentioned it is only suitable for running a motor.

looking inside the mill, it seems the 3 phase input goes through two transformers. the first transformer - i'm not sure what it does. the 2nd transformer makes single phase 120v that powers the controls and computer i think.

do i need to disconnect the output of the final transformer and wire that directly to a 120v plug? Where do i inject the VFD output?
