Fanuc Auxiliary (AUX) Axis, also referred to as 7th Axis, is an external, supplementary axis or axes that can be added to Fanuc robotic systems which allows a robot to have additional degrees of motion (7th axis, 8th axis, 9th axis, etc.). It is designed to enhance a robot’s capabilities by integrating with the robots existing controller. Robots can be paired with mechanical components like Fanuc Linear Rails, Positioners, or other servo driven components enhancing a robot’s functionality and operational scope. An Auxiliary Axis is designed to function independently or in conjunction with the robot’s primary motion, offering flexible and expanded capabilities.
