Chapter 6: System Operation
6.1 Status Panel Codes
The status panel display on the eMB-40R displays alpha-numeric codes that indicate the oper-
ating status of the robot, including detailed fault codes. The chapter on MotionBlox-40R gives
definitions of the fault codes. These codes provide details for quickly isolating problems during
troubleshooting. For more details, see Status Panel on page 30.
6.2 Brake Release Button
The robot has a braking system that 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, 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 eMB-40R and a Brake
Release button on the robot itself. See Brake Release Button on page 37 for information on the
Brake Release button on the eMB-40R.
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.
NOTE:
24 Volt robot power must be ON to release the brakes.
If this button is pressed while high power is on, high power will automatically shut down.
