6.1 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.
Instructions on configuring the Programmable E-Stop delay can be found within the SPEC
section of the
Instructions for Adept Utility Programs
manual. The default setting is
correct for most applications.
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, Joints 3 and 4 have electromechanical brakes. The brakes are released when
High Power is enabled. When High Power is turned off, the brakes engage and hold the
positions of Joints 3 and 4. There is a Brake Release button for Joints 3 and 4 on the
MB-40R and a Brake Release button on the robot itself. See
“Brake Release Button on
MB-40R” on page 38
for information on the Brake Release button on the MB-40R.
Brake Release Button on Robot
Under some circumstances you may want to manually position Joint 3 or Joint 4. For such
instances, a Brake Release button is provided. When system power is on, pressing this
button releases the brake, which allows movement of Joint 3 and Joint 4.
