New 2.2 Vfd For My Mill

Interesting about the different pots and problems. Agree, sounds more like belt/pulley noise and possibly bearings. Looks like it has a variable speed pulley set-up. I would run the motor at something between 30-90 Hz, no lower than 20Hz. You get more cogging, poor performance and overheating problems below this range, and above 90Hz, it starts to not sound so good. It may be possible to tweak some of the VFD parameters to get some further improvement. Probably easiest for you to post the changes you have made, or the program variables. If you need the default set of commands, PM me and I can send them to you if that makes it easier.

about the pots, would you think very old ones would have more problems? these are from the 70's....I have some newer ones. The problem I am having is it seems the motor cant keep up when I turn the dial like a time delay then all of a sudden it will take off and speed way up...Just so much to learn but thanks to people like you guys I will be past the head scratching in no time...lol I will go back and try and remember what all I changed as I went and write them all down or at least make a entire list and compare the different numbers. The default you mentioned are those the ones in the manual?

I use good quality pots from the 70s frequently. As long as they aren't worn out it doesn't matter when they were made.
