Normally you will have the limits wired in as you have them, then an E-Stop button wired to a different input.
The reason I do it that way is my E-Stops are all Double contacts, one side is the 5v for the breakout and Mach and the other is the E-Stop string that cuts power to all contactors in my machine. That way if a limit is hit the drives power is still kept to drives etc , just Mach stops motion, if the E-Stop is hit then Mach stops motion and also the AC to my drives and other motors are cut.
