10.2 Replacing the Ball Screw Spline Unit
A brake is mounted on the motor of Joints #3 and #4 to prevent the shaft from moving down
and rotating 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).
Move the shaft down to its lower limit before the replacement procedure following the
removal steps.

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.
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) Detach the wires/tubes from the end effector, and remove the end effector.
(5) This step is only for Cleanroom-model.
Remove the bellows. For details, refer to
Maintenance: 9. Bellows
.
(6) Remove the Arm Top Cover and Arm Bottom Cover.
For details, refer to
Maintenance: 3. Covers
