Robot Aux Axis Setup

In this video, we’ll walk through the process of setting up an auxiliary (aux) axis using FANUC’s independent axis library. Whether you're working with servo grippers, turntables, drills, or dispensers, understanding how to configure an aux axis is essential for optimizing robotic performance in multi-arm systems.

We’ll use a dual-arm robot setup as our example, where the aux axis is installed in the secondary robot controller. Through ROBOGUIDE simulation, we’ll demonstrate each step clearly, helping you visualize the configuration and understand the logic behind hardware assignments and software setup.

You’ll learn how to:

• Identify and assign hardware, amp, and brake numbers based on fiber optic cable routing
• Select the correct robot model and motion group for your system
• Choose the appropriate motor and configure its parameters, including RPM, current, and gear ratio
• Understand the implications of brake unit configurations and how to separate aux axis brake control from the robot amp
• Modify motor setups and axis configurations using Controlled Start without needing to reload software

Requirements for Setup:

• Dual-arm robot system (e.g., M-710iC/50)
• ROBOGUIDE simulation software
• Independent axis motor (e.g., AiS30)
• Knowledge of motor specs (RPM, nominal max current)
• Familiarity with gear ratios and load inertia
• Optional brake unit if independent brake control is needed

This video is ideal for engineers and technicians looking to expand their understanding of FANUC robot configurations, especially when integrating additional axes for specialized tasks. We’ll also touch on exceptions for certain robot models and how this setup method applies to other aux axis options like extended axis control and general positioners.

By the end of the video, you’ll have a solid foundation for setting up an aux axis and be better equipped to troubleshoot or expand your robotic system. Sign in to watch and take your configuration skills to the next level.
