I would like to install a VFD on a Hardinge DSM-A lathe (230V, 7A, 2HP motor, 25 KVA supply transformer on the pole outside) in a machine shop. I have never worked with VFDs before and am learning to do this on my own. The wiring and grounding should be okay and I have read alot about this. I am still trying to determine if I need a line reactor.
Someone at a VFD internet store recommended a Hitachi WJ200-015SF at $283. I have seen the Hy02D223B on a popular internet auction website at around $140, but there seems to be some mixed reviews about this Hy brand.
It would be nice if the VFD could be replaced easily with the same brand unit.
My question: What are some good, reliable, inexpensive VFDs that can work with the Hardinge?
Thanks for your time!
