For safety, connect the E-STOP button so it removes power from all machine parts that may create a direct or indirect hazard: drive power, and any actuators such as cylinders, pumps, solenoid valves, a plasma source, or other powered equipment. The E-STOP safety circuit must be designed for the specific machine and implemented by a qualified person in accordance with current regulations. It is not a CNC control function. The CNC controller may remain powered, but the E-STOP activation should be reported to the controller via a dedicated input. WARNING: Even if the controller supports emergency stop functions, it must not be used as the only safety measure. The diagram below is for reference only and should be treated as an example.

When connecting the E-STOP contact to a controller input, configure it in the software by assigning the selected input pin and—if you use an NC contact—enable signal inversion (DI Invert). This ensures that when the E-STOP button is pressed, the input status indicator turns green.
