First, thank you to all of the great posts on my set up, they made the install very easy!
I finally got the parts in and purchased and am up and running, but the motor makes a high pitched whine when running. It seems to be power related and not speed related. (Stays the same at all speeds or frequencies.) Once the FM50 stops the power output the whine stops. Motor is running forward correctly and I did check the programing to make sure it was supposed to run forward.
Could I have something else wire wrong? Or is this just normal with this set up or three phase motors? The POT I have is working correctly, a little too sensitive but working correctly.
