4.3 Using the Brake Release Button
Brakes
The robot has a braking system which decelerates the robot in an emergency condition,
such as when the emergency stop circuit is open or a robot joint passes its softstop. The
braking system will not prevent you from moving the robot manually once the robot has
stopped (and High Power has been removed).
In addition, Joint 3 has an electromechanical brake. The brake is released when High
Power is enabled. When High Power is turned off, the brake engages and holds the
position of Joint 3.
Brake Release Button
Under some circumstances you may want to manually position Joint 3 on the Z-Axis
without turning on High Power. For such instances, a ‘Z’ Brake Release button is located
above the robot status panel (see
Figure 4-2 on page 38 ). When system power is on,
pressing this button releases the brake, which allows movement of Joint 3.
If this button is pressed while High Power is on, High Power will automatically shut
down.
DANGER: When the Brake Release button is pressed, Joint
3 may drop to the bottom of its travel. To prevent possible
damage to the equipment, make sure that Joint 3 is
supported when releasing the brake and verify that the
end-effector and other installed tooling is clear of all
obstructions.
