A brake is mounted on the motor of Joints #3 and #4 to prevent the shaft from moving
down due to the weight 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 the replacement procedure following the
