Yamaha YK120X User Manual

The robot cable is pre-connected to each robot. Correctly install the other end of
the robot cable to the robot controller. For details on connections to the robot
controller, refer to Fig. 3-7 and the "YAMAHA RCX142 robot controller owner's
manual". After making connections, check the operation while referring to "6
Trial operation" in Chapter 1.

• Before connecting the cables, check that there are no bends or breaks in the

connector pins of the robot cable and that the cables are not damaged. Bent
or broken pins or cable damage may cause malfunction of the robot.

• Ensure that the controller is off before connecting the robot cable to the

controller.

The MOTOR connectors XM and ZM, and YM and RM each have identical
shapes. In addition, the PI connectors XY and ZR have identical shapes. Do
not confuse these connectors when making connections. Wrong connections
may result in malfunction and hazardous situations.

• If the connector installation is inadequate or if there are contact failures in

the pins, the robot may malfunction causing a hazardous situation. Recon-
firm that each connector is securely installed before turning on the control-
ler.

• To attach the PI connector securely, tighten the screws supplied with the

robot.

• Take caution not to apply an excessive load to the connectors due to stress

or tension on the cables.

Lay out the cables so that they do not obstruct the movement of the manipula-
tor. Determine the robot work area in which the robot cables will not interfere
with the load or workpiece picked up by the manipulator. (See "1-2 External
view and dimensions" in Chapter 7.) If the robot cables interfere with the mov-
able parts of the robot, the cables may be damaged causing malfunction and
hazardous situations.

Lay out the robot cables so as to keep the operator or any other person from
tripping on them. Bodily injury may result if someone trips on the cables.
