I was getting a bit confused about this as well, when I was looking at the Zapp site earlier (and especially as I haven't found decent English documentation for these devices). Thanks for the additional info.
One more question, though - when these boards talk about PWM spindle speed control, I am assuming that they have some kind of PWM->true analogue converter on board, which takes a PWM speed signal from Mach3 and gives a 0-10V (usually) signal that connects directly to the VFD. Is that right? Nothing else needed for Mach3 spindle speed control?

Yep that's correct just set mach3 to output PWM and away you go.!
