I wired it in series with my E-top switches, servo amp fault relays, etc. It works fine to stop the machine when the drive shuts down. (When I started doing rigid tapping that requires the spindle to reverse several times a minute it started tripping a LOT, I finally found out that the "electronic overheat" error meant it thought the motor was overheatin g due to all the reversals. I turned that feature off as the Bridgeport motor is made to take plug reversing all day long.
If you have a normally-closed E-stop switch, just put the NC contacts on the VFD in series with it.
