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?
