GX series Rev.2
WARNING
■
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.
■
Before performing any replacement procedure, turn OFF the Controller and
related equipment, and then disconnect 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.
■
Do not connect or disconnect the connector of M/C cable while the Controller is
turned ON. Connecting or disconnecting the motor connectors with the power ON
is extremely hazardous and may result in serious bodily injury as the Manipulator
may move abnormally, and also may result in electric shock and/or malfunction of
the robot system.
CAUTION
■
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.
■
Vibration (resonance) may occur continuously in low speed Manipulator motion
(Speed: approx. 5 to 20%) depending on combination of Arm orientation and end
effector load. Vibration arises from natural vibration frequency of the Arm and can
be controlled by following measures.
Changing Manipulator speed
Changing the teach points
Changing the end effector load
