WARNING
■
Do not
connect or disconnect the motor connectors while the power to the robot
system 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 r
esult in electric shock
and/or malfunction of the robot system.
■
To shut off power
to the robot system, disconnect the power plug from the power
source. Be sure to connect the AC pow
er 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.
After parts have been replaced (motors, reduction gear units, brakes, timing belts, ball
screw spline unit, etc.), the Manipulator cannot operate properly because a mismatch
exists between the origin stored in each motor and its corresponding origin stored in the
Controller.
After replacing the parts, it is necessary to match these origins.
The process of aligning the two origins is called “Calibration”.
Refer to Maintenance: 14. Calibration to perform the calibration.
