Chapter 4: MotionBlox-40R
Brake Release Button
The Brake Release button is located at the top right of the eMB-40R, as shown in Controls and
Indicators on eMB-40R on page 29. Under some circumstances you may want to manually pos-
ition Joints 3 and 4 without turning on high power. You can use the Brake Release button for
this purpose.
When 24 V power is enabled, pressing this button releases the brakes, which allows move-
ment of Joints 3 and 4. An additional Brake Release button is provided on the robot. For
details, see System Operation on page 87.
NOTE:
If this button is pressed while high power is on, high power will auto-
matically shut down.
Brake Release Connector
The 9-pin Brake Release connector provides low-active input signals to manually release the
brakes on Joint 3 and Joint 4. This can be used as an alternative to the Brake Release button.
The digital inputs on this connector meet the same input level requirements as the XIO inputs.
See XIO Input Specifications on page 41 for details.
