I am building my own controller which is using a MX4660 driver. I currently have the ESTOP+ and ESTOP- pins shorted as I am using the Estop circuit of my Masso G3 controller. If I wanted to add the MX4660 Estop, would it be as simple as wiring the two pins to either terminal of my NC Estop button? (The other NC switch of this button is connected to the Masso Estop). Also, what exactly does the MX4660 Estop do when activated (i.e., what happens electronically)?
