What would you need to do if the fault LED is illuminated on the SOP panel?

When the fault LED is illuminated on the SOP (Standard Operating Panel) of a FANUC robot, pressing the fault reset button is the appropriate action to take. This button is specifically designed to clear faults that may have occurred during operation. Faults can be triggered by various issues, such as overloads, errors in programming, or mechanical obstructions. Pressing the reset button allows the system to acknowledge and clear the fault condition, enabling the robot to resume its operations safely without needing to restart or change configurations.

Other actions, such as restarting the robot or changing the operational mode, might not address the underlying issue indicated by the illuminated fault LED. Additionally, simply increasing the power supply does not resolve the fault itself and could lead to further complications. Thus, using the fault reset button is a directed and effective method for handling the fault indication on the SOP panel.
