Use an SIO converter if it is desired to stop the entire system urgently by emergent stop via the teaching pendant.
The operation on the emergency stop switch of the teaching pendant can also be reflected when a gateway unit is
used as well.
Precautions on power supply and emergency stop circuit
*1 Refer to the specification list for the load current conducted per controller.
*2 The input current to the EMG- terminal per controller is 5 mA. When connecting a relay contact CR to
EMG- terminals of several controllers, make sure to check the capacity of the relay contact.
*3 When the teaching pendant is inserted to a controller, the controller automatically recognizes that it is
connected.
