AXBB has common ground (0V), so it will not work this way. You should use a 24V relay to short your wires. See the AXBB manual how to connect a relay to O2..O8. (O1 is reserved for charge pump, but it works the same way.)

is that my only option to get a relay.

You can also use an optocoupler+resistor instead of the relay.

Do all vfds have to use a relay to connect to this board then.

It's common to use a relay to start/stop the spindle, regardless of what board is used.

Can you recommend 1 then please.
