Pin 1

E-Stop Signal - To be used when using MPG E-Stop pendant button

Pin 2

E-Stop Signal

WARNING: To avoid damage to equipment or hazard to personnel, the system installer should wire the E-Stop button so that pressing the E-Stop button disables all drives and actuators on the machine. The E-Stop relay output on the MASSO should be wired to disable the axis drives and the spindle drive circuits.

Simple one E-Stop button wiring

The below wiring example shows how to wire and use only one E-Stop button. The E-Stop button is wired to ESTOP terminal Pin 2.

INFORMATION: In the below example E-Stop button on the MPG will not work.

Wiring only one E-Stop on MPG pendant

The below wiring example shows how to wire and use only the E-Stop button on the MPG pendant. Pin 1 on the ESTOP terminal is wired to positive of the power supply to get the MPG E-Stop button working.

Wiring multiple E-Stop buttons and MPG pendant E-Stop button

The below wiring example shows how to wire and use multipe E-Stop buttons and MPG pendant E-Stop button. All E-Stop buttons are wired in series to Pin 1 on the ESTOP terminal through the positive of the power supply. When any of the three external E-Stop buttons or MPG pendant E-Stop button is presses, MASSO will display an E-Stop alarm on the screen and the "ES" (E-Stop output) singnal will go LOW.

Wiring E-Stop output signal to relay

A special output signal "ES" (E-Stop output) is available on the outputs terminal. This output is internally hardwired to the E-Stop button signals and goes LOW when the E-Stop button is pressed.

CAUTION: This output must be used to control a relay and then the relay must be able to disable all drives and actuators on the machine. The user should not rely on the software to stop the axis, spindle or other actuators in case of an emergency and must disable all drives electrically.

Here is a great video from CNCnutz explaining the entire process
