Everything I've read on VFDs says do not feed them from a transformer. Nor can
you put a transformer between the VFD and the motor. Most of them say *nothing*
should be between the VFD and the motor, direct connection only. The one on my
1943 Monarch 12CK lathe recommends a noise filter on the input side to prevent
noise feeding back into the line from the VFD from getting to other stuff on
the circuit.
