6.1.7 Examples of safety measures
Two emergency-stop input circuits are prepared on the user wiring terminal block of the controller. Create a cir
-
cuit as shown below for safety measures. In addition, the figure shows the normal state which is not in the emer
-
gency stop state.
[Caution] Since we have omitted the information in part because of explanation, there is the section different
from the product. Also refer to Page 95, "(1) External emergency stop connection [supplementary
explanation]" and Page 54, "3.6.1 Connection of the external emergency stop" .
[Note] In the emergency-stop related wiring by the customer, if the coil (is not the contact points) of the relay
prepared by the customer is connected to the controller, please be sure to implement the measure against
the noise by the customer in the coil section. And, please also take the lifetime of noise suppression parts
into consideration.

<Wiring example 1>: Connect the emergency stop switch of peripheral equipment to the robot controller.
The power supply for emergency stop input uses the power supply in the robot controller.
<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.
*1)EMGIN1/2, and EMGOUT1/2 have
the two terminals separately, and
show that they are the two lines.
Always connect the two lines.
*2) 1A/1B, and 2A/2B terminal of
EMGIN is short-circuited at
factory shipments.
*3)5A/5B, and 6A/6B terminal of
EMGIN is short-circuited at
factory shipments.
Notes) If "*2" and "*3" are removed,
it will be in the emergency stop
state.
*4) The emergency stop button of the
robot controller operation panel.
*5) The emergency stop button of T/
B connected to the robot
controller.
*6) Emergency stop input relay.
