Brakes

Joints 1, 2, and 4 have dynamic brakes that are used only to stop the robot in an emergency

condition, such as when the emergency stop circuit is broken or a robot joint passes its

softstop. These brakes will not prevent you from moving the robot manually once the

robot has stopped (and High Power has been removed).

Joint 3 has an electric brake. The brake is off when high power is enabled. When High

Power is turned off, the brake actuates and holds the position of Joint 3.

Under some circumstances you may want to manually position Joint 3 without turning on

High Power. For such instances, a brake-release button is located on the robot backplate

(see Figure 5-6). When system power is on, pressing the button releases the brake, which

allows movement of Joint 3.

CAUTION: 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 the Joint 3 is supported while releasing the brake and

verify that the end effector or other installed tooling is clear of all

obstructions.
