Emergency stop
The robot arm enters an emergency stop when either an emergency stop button is pressed or when a high-speed
collision occurs. When in an emergency stop:
•The robot arm applies internal brakes to ensure rigidity.
•Attached end effectors and devices release grip and turn off.
•The TeachMate LEDs turn red.
•Forge/OS notifies you the robot is in an emergency stop and the margins are red and display “Robot
Error.”
If an emergency stop occurs because of an emergency stop button, Forge/OS instructs you to turn the emergency
stop button clockwise, releasing the stop. Once the stop is released, the robot arm enters idle mode.
If an emergency stop occurs because of a high-speed collision, Forge/OS instructs you to clear the system through
the teach pendant, connected to the controller of the robot arm. Follow all on-screen instructions to restart the
robot arm from the teach pendant. Once the stop is released, the robot arm enters idle mode.
Protective stop
The robot arm enters a protective stop when it encounters an obstacle that triggers the human-safe force sensors
inside the robot arm. When in a protective stop:
•The robot arm applies internal brakes to ensure rigidity.
•Attached end effectors and devices release grip and turn off.
•The TeachMate LEDs turn yellow.
•Forge/OS notifies you the robot is in a protective stop and the margins are yellow and display “Robot
Warning.”
To clear the protective stop and turn on the robot arm, tap Turn Robot On from the Robot Mode panel, see
section the “Robot Mode” section of the “Control Suite” chapter for more information.
Reduced mode
The robot arm enters reduced mode when a connected safety device detects a condition that causes the robot
arm to slow movement to maintain a safe work environment. Reduced mode can be triggered by a person or
object entering the work area or coming within a defined distance of the system.
•The robot arm continues to execute the task at a reduced speed.
•The TeachMate’s LEDs blink green.
•Forge/OS notifies you the robot arm is in reduced mode by displaying “Reduced Mode” in the margins.
To return the system to Active mode, clear the condition that triggered the safety devices.
