Before performing any replacement procedure, turn OFF the robot control system and then pull out
the power plug from the power source. Performing any replacement procedure with the power ON
is extremely hazardous and may result in electric shock and/or malfunction of the robot system.
(7)
Do not insert or pull out the motor connectors while the power to the robot system is turned ON.
Inserting or pulling out the motor connectors with the power ON is extremely hazardous and may
result in serious bodily injury as the Robot may move abnormally and may result in electric shock
and/or malfunction of the robot system.
(8)
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.
(9)
Joint #1, #2 and #4: repeatedly operating the joint in a motion angle less than 5 degrees may result
in shortage bearing oil film and shorten the service life of joint. To avoid shortening the service life
of joint, please move the joint over 50 degrees for about 5 to 10 times per day.
(10)
Joint #3: if arm
’s vertical
move distance is shorter than 10mm, please move the joint over half of
the maximum motion range for about 50 times per day.
(11)
When the robot is operating at a low speed (about 5~20% of rated speed), continuous vibration (or
sympathetic vibration) may occur as the direction of arm and end effector load. The following
measures may reduce vibration caused by natural vibration frequency of arm.
•
Change operating speed
•
Change teaching point
•
Change the load of end effector
(12)
Vibration of the front end of the arm may increase when J3-axis upper side or lower side is moving,
according to the weight and inertia of the grippers. This is due to an increased distance between
the end and head of the shaft, which leads to a change in inertia. Adjust speed etc. according to
item 11 when this vibration causes a negative effect on robot operation.
(13)
Do not touch Joint #3 and Joint #4 directly by hand during greasing and teaching. Touching Joint #3
and Joint #4 frequently may cause rust.
(14)
Please remove any tape of seal on oil paint surface with care, as this might incur damage to the
paint.
(15)
Please be advised that robot joints and parts may become hot after operation with high payload or
speed that can cause minor skin burn. Only perform maintenance once these parts have cooled
down.
