New Build 1000x600x200mm (newbie)

[JAZZCNC]

I'll be using the C6 with C35 from same site, I checked with their support and they confirmed that they work together so I assume it would work and mach3 could output the required frequency(step) signal, did I miss something? please enlighten me :D

Yes they will work fine. The difference is that with a Step based spindle control you use or lose an Axis output. With PWM then you don't.

Read the manuals how to connect them:

This NOT a Huanyang Vfd.!! The setup is similar but the connection terminals are different names and it's not wise to presume just because they are similair labeled they actual do the same as Huanyang or any other Vfd.

Also looking at the table for VFD you provided the Analog and Digital input Logic (which is 24V not 5v) share the Same ground so maybe can't use this board.? Check with a meter to be sure but normally Analog as it's own isolated common.!

Edit: Also the Spindle 99.9% probably won't have a Ground wire. It may have 4 connections but one won't be used. Again use meter to find one that isn't which is often pin4 (look close they will have numbers)
Regards using the PE: Then take the cable shielding at the VFd end back to PE connection. Leave spindle end shield unconnected.

Some people use the 4th connection in spindle to Ground the spindle but I find it's not required if machine frame is grounded.
