Aluminium Profile Type Router - Initial questions

[CNCRY]

Still no speed control on the spindle when connected to AXBB-E
Cabled as above with VFD>AXBB-E
FOR > O2
DCM > 24V0
VI > AO1
ACM > 5V0 (power out)



When I enter in MDI M3 S2500 - the O2 pit diagnostic lights up and spindle FOR lights up and stops flashing, like this:



But Speed sits at 0!
I checked the voltage between AO1 and 5v0 at S2500 and it seems to be 0 so possibly the issue.

Here are my settings



I noticed "SPINDLE CW" light comes on in UCCNC diagnostics too.
Am I missing some config here or something obvious as I'm stumped!

Thanks
Ryan
