I use a FM50 VFD to run my Millrite, I have used it for about 5 years. The motor is a GE pancake of about 1 hp (the machine is about 25 miles away so I can't be certain). The VFD is 220/1ph input, 220/3 ph output. I have it set up to utilize the original drum switch, FWD OFF REV. It has always worked well but it has the annoying habit of starting to turn in the direction that I select but immediately reverses direction and rotates at a very low speed. If I switch it back to OFF and restart it it will run fine. Sometimes it takes cycling the switch 2 or 3 times before operating correctly, other times it starts normally without any "shutter".
Back when I was researching VFD' s I recall someone on a forum had the same problem and a solution was posted. IIRC it was a setting in the VFD parameters but I don't remember what it was. It is just an annoying problem that I would like to fix. Any suggestions
