I went to home depot for the switches, housings and conduit. I think I have about 10 bucks in it. I am using a $0.99 half watt linear 10k pot from Radio Shack and a $1.25 knob! My VFD is a Minarik open frame type. No programming. No Cabinet. No user controls. Mounted it on the back of the lathe cabinet down by the floor (where it is cooler) All the parameters are adjusted with pots on the device. I just disconnected my Rotary Phase Converter and connected the VFD. I use the Drum Switch for off on and reverse. If I want the braking, I use the switch on the wall. The F/W wall switch can be used for a gentle brake, stop, and gentle start the other direction. Not really needed. I made a little mark by the pot where the 60 hz setting is. I leave it there unless I really need to change the speed. 60 HZ is where the motor is happiest. Once in a while, if I slam the drum switch from forward to reverse and back the VFD will fault. I just reach up, flip the enable switch off, then on and go on my merry way. I had to crank it up just a bit when it started tripping on heavy cuts. I have a lot of faith in the engineers that design those things. I have adjusted the over current at the minimum to make it work. I'm not worried about hurting anything. I have another unit sitting on the shelf. (Got 2 used units for $85). I have been using this unit for about a year now. As soon as I find a deal on a 3 phase motor that will fit my mill, I will use the second one.
