(17) Do not remove, alter or stain the warning labels.
WARNING
If warning labels are removed or difficult to see, necessary cautions may not be
taken, resulting in an accident.
• Do not remove, alter or stain the warning labels on the robot.
• Do not allow the warning labels to be hidden by the device installed to the
robot by the user.
• Provide proper lighting so that the symbols and instructions on the warning
labels can be clearly seen even from the outside of safeguard enclosure.
(18) Protective bonding
WARNING
Be sure to ground the robot and controller to prevent electrical shock.
(19) 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.
(20) Do not use the robot for tasks requiring motor thrust.
! CAUTION
Avoid using the YK-XG series robots for tasks which make use of motor thrust
(press-fitting, burr removal, etc.). These tasks may cause malfunctions of the
robot.
(21) If the X, Y or R axis rotation angle is small
! CAUTION
If the X, Y or R axis rotation angle is smaller than 5° so that it always moves in
the same position, an oil film is difficult to be formed on the joint support bear-
ing, possibly leading to damage to the bearing. In this type of operation, add a
movement so that the joint moves through 90° or more, about 5 times a day.
