I have a lathe with a 2hp 3 phase motor on it. I switched from a static phase converter to a VFD. The VFD is rated for 3 hp. I am having torque problems. With the static phase converter you could not stop the chuck for anything. With the VFD I can stop the chuck with my bear hands at 1000 rpm. I can stop the chuck alot easier at lower rpm. Its not easy buy I can stop the chuck. I know nothing about vfd's. My friend has 3 of them on 3 different machines for 3 years so I bought the same one on ebay for $140.00. Its a Huanyang Inverter. I set all the parameters. One problem I am having is the name plate on my motor does not tell you the HZ. So I looked at alot of other 2 hp 3 phase motors and they are all about 60 HZ so thats what I set it at. Any help at all would be greatly appercaited The motor I have is a Rockwell 2 hp model 96-320, frame66, 1725 rpm, 6/3-7/3 amps. Its driving me nuts. I don't want to go back to the static converter. Thanks
