The external emergency stop function of controls the contactor and turns off the power by directly receiving 

signals from the emergency stop switch.

Besides the emergency stop input from the NC controller, double-protection when an emergency stop 

occurs can be provided by directly inputting an external emergency stop to the EMGX of CN9 connector 

on the servo/spindle drive unit. Even if the emergency stop is not input from CNC for some reason, the 

contactors will be shut off by the external emergency stop input from the EMGX of CN9 connector. 

When the external emergency stop input and contactor are installed, compliance with "EN60204-1 

category1" is basically possible.

1. Always input the external emergency stop signal to the drive unit controlling the contactors.

2. The emergency stop signal input to the CNC side cannot be used as a substitute for the external 

emergency stop function.

3. To provide double-protection when an emergency stop occurs, the emergency stop input of NC 

and the external emergency stop input are always wired from same emergency stop switch.

Stop Categories in EN60204-1

Category 0 : The power is instantly shut off using machine parts.

Category 1 : The drive section is stopped with the control (hardware/software or communication 

network), and then the power is instantly shut off using machine parts.

(Caution) Refer to the Standards for details.

Refer to Section 9.2.5.4.2 in EN60204-1: Safety of Machinery Electrical Equipment of Machines - Part
