Brakes
The AdeptThree has "fail-safe" air release brakes on all joints. These
brakes are on whenever
are intended primarily to restrict arm movement when high power is off,
but they also assist in stopping robot motion when the Emergency Stop
circuitry is activated or when there is a robot motion error. These brakes
are not designed to be used as a routine method of stopping robot
motion.
Under some circumstances it may become desirable to manually position

system power is on, pressing the button releases the brakes, which allows
movement of the arm. If this button is pressed while

When the brake release button is pressed, the quill (Joint 3)
may drop to the bottom of its travel. To prevent possible
damage to the equipment, make sure that the quill is
supported while releasing the brake and verify that the
end effector or other installed tooling is clear of all
obstructions.
