I converted my Grizzly 4003 with a Teco FM50 and Lesson 2HP 3PH motor. All works great. Wired up VFD control side to factory apron switch, estop, inch and added a pot dial.
I set my max Hz level to 75 for a little extra speed when needed.
The Lesson is an inverter duty motor.
My question is when I turn the pot dial up fast from 60 hz or below to 75hz, the motor slows down. If I turn the dial slowly from 60 to 75, it ramps up the speed and maintains speed.
I'm guessing it's the way the VFD works or it's the cheap pot dial. Just wondering, I'm no electrician, lol.
