Note1) If functional safety is not ensured (such as when the safety extension unit is not connected and no origin position has been set)
or the robot servos are turned off, the status indicator LED will flash.
CAUTION
The following table shows conditions of dedicated output signals that determine the robot status (shown by
the color and behavior of the status indicator LED).
The status of dedicated output signals is checked from the top to the bottom of the table, and when the con-
dition is met, the status of the robot will be determined accordingly.
Refer to this table when installing an extra status indicator light.
For information on the dedicated output signals, refer to the separate "Instruction Manual: Detailed explana-
tions of functions and operations" and "Collaborative Robot: Detailed explanations of functions and opera-
tions".
