I, too, have a variable speed machine.? The original VFD was a TECO but it went bad and I purchased something else from FactoryMation.? My VFD is kept at 60 Hz and I use the variable speed crank to change RPMs.? That way I don't lose any power.? I had tried a cheap Chinese one after the TECO failed but, among other things, the terminal connections were too small to take standard crimp-on connectors.
