A brake is mounted on the Joint #3 motor to prevent the shaft from lowering 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).
LS6:
A brake is mounted on the motor of Joints #3 and #4 to prevent the shaft from

Joint #3 motor
Removal
(1) Turn ON the Controller.
(2) Push down the shaft to its lower limit while pressing the brake release switch. Be
sure to keep enough space and prevent the end effector hitting any peripheral
equipment.
LS3:
The brake release switch affects only Joint #3. When the brake release switch
is pressed, the Joint #3 brake is released.
Be careful of the shaft while the brake release switch is being pressed because
the shaft may be lowered by the weight of an end effector.
LS6:
The brake release switch is applied to both Joints #3 and Joint #4.
When the brake release switch is pressed, the respective brakes of the Joint #3
and Joint #4 are released simultaneously.
Be careful of the shaft falling and rotating while the brake release switch is
being pressed because the shaft may be lowered by the weight of an end
effector.
(3) Turn OFF the Controller.
(4) Remove the Arm Top Cover.
