■ 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 result 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 power cable to a power receptacle. DO NOT
WARNING
connect it directly to a factory power source.
■ Before performing any replacement procedure, turn OFF the robot system 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.
■ Be careful not to apply excessive shock to the motor shaft when replacing the
motors. The shock may shorten the life cycle of the motors and encoder and/or
damage them.
■ Never disassemble the motor and encoder. A disassembled motor and encoder
CAUTION
will cause a positional gap and cannot be used again.
After parts have been replaced (motors, reduction gear units, a brake, 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 Robot
system.
Because of that, it is necessary to perform calibration (encoder rest and calibration) to match
these origins.
Refer to "17. Calibration" to execute the calibration.
