Fitting a pot to a Chinese Spindle VFD

[EddyCurrent]

Clive, it sounds like a neat and tidy solution, as an alternative you could have connected a pot to the 0-10v and analogue input. I did this with my pin router but used a 10 turn pot with a scale dial to get precise speed control, not that you actually need it to be so precise. It also means you can mount it remotely if required, such as on the front of a panel.

Yes Eddy I was aware of those pots but I did a bit of research and I deemed it unnecessary to have such precise control over the speed as soon as you set the speed and start cutting I am sure it will change. I find it very easy to adjust the speed to within a couple of hundred revs. My VFD will be outside of my control box, but next to it on the wall. For me the £1.70 spent saves me keep messing with the controls on the VFD ..Clive
