<Wiring example 4>: Connect the emergency stop switch of peripheral equipment, and the door switch to two controllers, and it
interlocks. Connect the enabling device to the robot controller.The power supply for emergency stop input
uses the power supply of peripheral equipment. Monitor the emergency stop state by the peripheral
equipment side.
<Operation of the emergency stop>
If the emergency stop switch of peripheral equipment is pushed, the robot will also be in the emergency
stop state. And, if the emergency stop switch of OP or T/B is pushed in the state of the power of con -
troller OFF, peripheral equipment state can be the emergency stop also.

*4) Refer to the Standard specification manual or the Special specification manual for the enabling device.
*5) The emergency stop button of the robot controller. (Only specification with the operation panel.)
*6) The emergency stop input detection relay uses the controller's internal safety relay control. If the emergency stop input detection relay
is switched OFF, emergency stop is detected and the safety relay is also switched OFF.

*1)Each of the connectors, EMG1 and EMG2, are assigned with the
same pin number, creating two systems for each terminal. It is
absolutely necessary to connect the two systems.
If necessary to stop two robots simultaneously by one emergencystop
switch please use the 4 contact type emergency stop switch.
*2)The T/B emergency stop button connected with the controller.
*3)Emergency stop input relay.
