(2) Wiring the emergency-stop switch
In many cases multiple controllers are used in a single system.
To provide an emergency-stop function for the entire system, the controller circuit is designed in such a
way that a single EMG switch is able to actuate an emergency stop in all connected controllers.
[Internal emergency-stop circuit]
(Note) The current consumption of the internal relay is 10 mA or less.

Cutoff voltage Cutoff current
EMG switch on teaching pendant 30 VDC 3 A
PORT switch 24 VDC 0.1 A
[Example of recommended circuit]
(Note) To cut off the motor drive power supply in conformance with safety category 2, connect 24V to the
EMG terminal and a contactor or other contact device to the MPI/MPO terminals. (Refer to 4.2.3.)
