<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.
