Thank you guys, I think I'm going to stick to what I was planning. Use the alarm component to inhibit the feed or turn off the machine via the motion.enable pin and use the external e-stop button to turn off the contactors that feed the servos. I have it this way on the other machines but I can't access to the config right now.
It's funny but being used to only turn on and put the machine to work makes me forget some basic stuff I already did a few years ago. I need to play with this stuff more often I guess :).
