If you are using Mach3 then you will may have to play with the Pulley Ratio 100Hz PWM setting is also a good starting number

You need the Breakout Board 0-10v working correct before you connect it to the VFD Drive

Do you have a PDF VFD Manual you can post
I have 12v 5A PSU powering BOB. I know about that. Breakout board is working perfectly before it is connected to the VFD. Every voltage is correct and outputs are working as expected.

VFD manual is attached here.
