To actuate an emergency stop on the entire system using the emergency stop switch on the teaching pendant, use a
SIO converter.
You can also reflect the operation of the teaching pendant’s emergency stop switch when a gateway unit is used.
Notes on power supply and emergency stop circuit
*1 Refer to the specification list for the load current of one controller.
*2 The input current at the EMG- terminal of each controller is 5 mA. If the relay contact CR is to be connected to
the EMG- terminals of multiple controllers, check the contact capacity of the relay.
*3 When the teaching pendant is plugged into the controller, the controller automatically recognizes the
connection.
