I was just browsing through the 29D VFD manual, thinking about your situation. Based on what you've already done, and what you're describing.... I'm convinced that if you read up on, and start tweaking the trim pots.....you'll get it worked out.
I tried looking up the motor, but couldn't find it. Every time I read that it's a 3490rpm motor, I kinda cringe..... maybe because I've never worked with one of those rpm motors connected to a VFD.
That being said, I've found the folks at Wholesale motor to be knowledgeable and helpful.... in all the years I've dealt with them, I can only remember having to leave a message twice....and it was a few days before they called back. Keep trying.... I suspect that if you can talk to one of their tech people....they'll have the problem diagnosed, and give you a fix in no time. Keep us posted on what happens!
