Don't understand any of them to be honest, will just keep searching, im sure someone must have the same vfd and uses for a spindle lol

Glad to hear you're getting somewhere.
Starting at 9000rpm isn't 'bad'.
What you need to bear in mind is whenever I see these cheapish spindles they generally say 'don't run it below 8000rpm'. They overheat and die. So in effect you are now prevented from making that mistake.
The relay itself turns on with M3 command yes?.
May be another peramiter for external control related to direction. Or a peramiter that swaps default direction which could explain why fwd ran the wrong way before.

I am just upgrading my cnc router to an AXBB-e from a couple of breakout boards and a spindle board. I am just a little confused over the use or not of a spindle relay. to the vfd. The original setup used a spindle board (opto isolated Digital to Analogue convertor) which had 2 relays relay for the spindle and Coolant. I am using a Huanyang 2.2Kw vfd. In the AXBB instructions it does not use a relay for the VFD and yet I see on the forum people say you should use a relay. Obviously I need a relay for the Coolant pump but should I use a relay for the vfd? Is it purely for the isolation?
Any thoughts?
Thanks, Paul.
