I have a Hitachi sv drive on my lathe (2hp) and can get the spindle speed down to 2 rpm and still has enough torque that I can't stall it.
Customer service is a big plus too. I had a conversation with someone at Hitachi via e-mail, who answered a couple of questions I had about setting up my VFD. I later found out he was the head engineer for the company.


Then again, I've never seen a bad word about the TECO units either......
