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 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

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.

CAUTION

■

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.

Do not mount Joint #4 motor unit on the other joints

since

specification is different from that of Joint #2 or #3

motor units. Marking is applied on the motor case of

Joint #4 motor.

■

Never disassemble the motor and encoder. A disassembled motor and encoder

will cause a

positional gap and cannot be used again.
