WARNING
■
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
extremely hazardous and may result
in serious bodily injury as the Manipulator
ormally, and also may result in electric shock and/or malfunction of
to the robot system, pull out 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.
performing any replacement, turn OFF the Controller
uipment, and then pull out the power plug from the power source.
Performing any replacement with the power ON is extremely hazardous and may
result in
electric shock and/or malfunction of the robot system.
CAUTION
■
Be careful not to apply excessive shock to the motor shaft when replacing
s. The shock may shorten the life cycle of the motors and encoder and/or
Never disassemble the motor and encoder.
A disassembled motor and encoder
will cause a positional gap and cannot be used
again.
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: 13. Calibration to execute the calibration.
