T3-B T6-B Manipulator 1. Safety
■ To shut off power to the robot system, disconnect the power plug from the power
source. Be sure to connect the AC power cable to a power receptacle.
DO NOT connect it directly to a factory power source.
WARNING
■ Whenever possible, only one person should operate the robot system. If it is
necessary to operate the robot system with more than one person, ensure that all
people involved communicate with each other as to what they are doing and take
all necessary safety precautions.
■ Joint #1, #2, and #4:
If the joints are operated repeatedly with the operating angle less than 5 degrees,
they may get damaged early because the bearings are likely to cause oil film
shortage in such situation. To prevent early breakdown, move each joint larger
than 50 degrees for about once an hour.
Joint #3:
If the up-and-down motion of the hand is less than 10 mm, move the joint a half of
the maximum stroke for about once an hour.
CAUTION
■ Oscillation (resonance) may occur continuously in low speed Manipulator motion
(Speed: approx. 5 to 20%) depending on combination of Arm orientation and end
effector load. Oscillation arises from natural oscillation frequency of the Arm and
can be controlled by following measures.
■ Manipulator may be heated due to motor heat etc. Do not touch the Manipulator
until temperature falls. After confirming that the temperature of the Manipulator
falls and is not hot when you touch it. Then perform teaching or maintenance.
