    Not directly. E-Stop is typically a pair of NC contacts, and drive fault is typically an open collector output.

    You could wire all your drive fault outputs to a small auxiliary relay, and then wire that relay in series with the E-Stop.

    Something like this. Pretty much any small relay SPDT relay will work, as long as it has the right coil voltage.

    Yep, that's it. Don't forget the diode to keep the drives safe from back EMF.
