9. Stopping time and stopping distance at emergency stop
When the emergency stop button is pressed during robot operation or the power supply to the controller is
turned off, the stopping time and stopping distance or angle of the main 3 axes change depending on the
operation speed as shown below. The following figures show typical time and distance or angle needed for
each axis to come to a stop after a stop signal is initiated when the robot arms are fully extended while 3
types of tip mass (33%, 66% and 100% of maximum payload) are loaded.
