BEST vfd drive connection to Carbide Motion Board

Since @Vince.Fab has joined the spindle club, I thought I’d share how I set up my BEST vfd to drive my spindle motor from the Carbide Motion Board (CMB). I wanted to use the PWM output of the CMB to control the ON/OFF of my spindle as well as the RPM. Unfortunately, the BEST vfd I purchased only accepts a 0-10V control voltage and not 0-5v delivered by the PWM pin on the CMB. To get around this I purchased a module that converts the 0-5v PWM into a 0-10v signal. A link is here (order the Num…

I have the 1000hz version of this and spent the whole day cobbling up a much bigger wired vfd cable to take that out of the equation.

Still only seeing a max 2amp draw at max speed when trying to stop by hand.
