Help needed to connect my VFD to the AXBB controller

[CharlieRam]

Cheers Doddy, we are getting somewhere! The forward and reverse now function on the vf d but still no speed do I need to connect the acm to 24v0 too or is it something to so with my ucnc setup as its showing actual speed at 0 even though it's set at 5000?

Nope, that diagram shows the analogue output AO1 referenced to 5V0, so you need to connect 5V0 to ACM (which I believe you said you already did). (or connect 5V0 and 24V0 together).

You could try connecting the VI input to the VFD to the 5V+ supply (obviously, having disconnected it from the AO1 output first). Then M3 should command a 12000RPM output from the VFD (not variable) - that would confirm that the VFD analogue input is correctly configured. And that would leave just trying to work out why both UCCNC and the AXBB aren't playing with the PWM output control. It feels like a UCCNC configuration thing but your screen shot looks basically right. I can dig out my settings for my Starmill (I have UCCNC driving EITHER that or the Sieg, but it's currently wired into the Sieg which has a manual spindle control).
