    So far right diagram is 24v coming in from the safety circuit running through bob relay contact to control VFD then into the coil of a seperate relay controlling VFD mains power.
    Left diagram is adding another relay in to control run signal on off simutaneously with power on off once the BOB relay is activated.
    Middle option is to get a 3 or 4 pole relay (4 pole - leaving a space between power and control) to wire it all in as one, but would this cause an issue with interference?

    No Dan you don't want to be turning the VFD On/Off every time you run the spindle. You want the VFD power controled thru the E-stop so if an emergency it's shut down.
    The run signal is used to start/stop the spindle spinning. Use the BOB relay output to control On/off just like Eddy shows lower down. Then have the VFD POWER controlled via a Relay in the 24V E-stop system.
