Fig. 8-2: Details of the plug
The pins used on the connectors (3BC: 14 wires, 8 x 0.20 mm², 2 x 0.75mm², and 4 x 1.25
mm²) are connected to the stand and arm with individual wires.
In the standard specification, pins 7 and 8 are connected as follows:
• To the 3BC connection for the collision sensor on the U arm.
• To the 3BC connection for the collision sensor on the robot controller.
Pins 7 and 8 of the respective 3BC connections on the connector plate and U arm are
connected to each other.
For the wiring, see the following figure, "Connecting diagram for internal connections."
The internal connections of the robot are shown in the following diagrams "Connection
diagram A" and "Connection diagram B".
