Probably the easiest way would be to use a shot pin of some sort if you can mount such a thing. You would rotate the spindle slowly and release the pin and whan it came round to the hole it would pop in and lock the spindle. You could have a limit switch to show when it was engaged (and disengaged) and that could then be used to stop the VFD.
