CHAPTER 1 Using the Robot Safely
(18)Protective bonding
WARNING
Be sure to ground the robot and controller to prevent electrical shock.
(19)Always connect the robot to the specified controller.
WARNING
The controller for the YK120X series robots (YK120X, YK150X) is designed to
provide 24V output and the model name "RCX142-T" is shown on the serial
number label (see Fig. 2-5). Do not connect other controllers to the YK120X
series robot. If operated from a controller other than the RCX142-T, the robot's
motors may be damaged.
(20)Avoid fastening any cable or tube prepared by the user with the
machine harness, user signal wires or air tubes of the robot.
WARNING
Do not utilize the machine harness, user signal wires or air tubes of the robot to
fasten any cable or tube prepared by the user, as this may break the robot
harness wires or user signal wires causing malfunction of the robot. This will
also result in poor positioning accuracy.
(21)Do not use the robot in locations subject to strong vibrations.
WARNING
Do not operate the robot in locations subject to strong vibrations. The robot
installation bolts might work loose and the robot topple over. The bolts on the
robot body itself might also loosen, causing parts to fall off, etc.
(22)Be sure to make correct parameter settings.
!
CAUTION
The robot must be operated with correct tolerable moment of inertia and accel-
eration coefficients according to the manipulator tip mass and moment of iner-
tia. If this is not observed, premature end to the life of the drive units, damage to
the robot parts or residual vibration during positioning may result.
(23)Do not use the robot for tasks requiring motor thrust.
!
CAUTION
Avoid using the YK-X series robots for tasks which make use of motor thrust
(press-fitting, burr removal, etc.). These tasks may cause malfunctions of the
robot.
