Maybe I'm just dense, but I'm having a hard time getting my head around how to interface Mach3's PWM speed control output, with a VFD. The VFD I have has three speed control inputs, 0-5vdc, 0-10vdc, and 4-20ma. Standard industrial control parameters. Is there a way to take the Mach3 PWM signal, and converts it to 0-10vdc? I'd like to be able to use this VFD if there is a way to interface it with Mach.

Thanks for any help, brain is hungry!
