12.1. Emergency Stop
Description The Emergency Stop or E-stop is the red push-button located on the Teach Pendant.
Press the emergency stop push-button to stop all robot motion. Activating the
emergency stop push-button causes a stop category one (IEC 60204-1).
Emergency stops are not safeguards (ISO 12100).
Emergency stops are complementary protective measures that do not prevent injury.
The risk assessment of the robot application determines if additional emergency stop
push-buttons are required. The emergency stop function and the actuating device must
comply with ISO 13850.
After an emergency stop is actuated, the push-button latches in that setting. As such,
each time an emergency stop is activated, it must be manually reset at the push-button
that initiated the stop.
Before resetting the emergency stop push-button, you must visually identify and assess
the reason the E-stop was first activated. Visual assessment of all the equipment in the
application is required. Once the problem is solved, reset the emergency stop push-
button.
