Include vfd failure in your estop chain. Ie, when the vfd's spindle-at-speed pin goes low, drive the iocontrol.0.emc-enable-in low. You may need some logic to have this only happen while the machine is trying to execute a commanded motion, perhaps while motion.in-position is false? I'm not really sure about this part.
