    Arduino. Yep those are very high on my list of things to toy with, just wasn't sure what I'd use it for but now I have a plan!

    Sorry last stupid question. Using this approach with that sensor would I measure current on then single phase input side of the vfd or on the output side or does it even matter?

    Output side - you want the line current. You could use the current sensor to measure the frequency of the current, then scale that to read spindle speed... just for fun.
