of the end effector while the power to the Controller is OFF or while the motor is in OFF
status (MOTOR OFF).
Note that the brake will not work during the replacement procedure.
Move the shaft down to its lower limit before starting the replacement procedure by
following the removal steps from (1) to (4).

(4) Turn OFF the Controller.
(5) Remove the Arm #1 side cover of the Joint #2 side.
