* The belt tensile jig is an assembly jig. Use the jig when adjusting belt tension.
The brake is mounted on each joint to prevent the arm from lowering due to its own weight while the
Controller power is OFF or the motor is OFF status. The brake does not work during replacement.
Be careful when performing maintenance work.
The motors are common for Joints #4, #5, and #6.
The Joints #5 and #6 motors have an identification label for preventing misconnection of the connectors.
The label is not necessary for the Joint #4 motor. (There is no connector identification label for the
Joint #4.)
