ya, i thought the meter was reading funny too.
it reads 13v on the input and 1.56v on the output at 100% speed.
how does the vfd work with this i have no idea.

You are measuring it while running? That never worked for me. I was measuring the output from the speed controller but not hooking it up.

yes while running
my mill say 10v while running full speed.
this thing is very strange.
i dont mind what it does/says as long as it makes parts. lol

I have mine working as of this week like you. I do however got the proper voltage output now though I think I fried a C6 in the process (or a chip in it). Oddly enough the way my Bardac drive is wired is supposedly incorrect according to anyone that reads the manual (some of who I know have extensive electronic backgrounds). But it is working just as it should. I am going to talk to the manufacturer just to verify my safety and use but like you and your voltage issue, it works right and I dont know why. Odd
