What are the major axes in the FANUC system?

In the FANUC system, the major axes designated as J1, J2, and J3 typically refer to the primary rotational joints of a robotic manipulator. These axes are crucial for the robot's ability to perform complex movements and tasks in a three-dimensional space.

The J1 axis usually represents the base joint, allowing the robot to rotate around its vertical axis. The J2 axis often corresponds to the shoulder joint, facilitating movement in a primarily up-and-down motion. The J3 axis functions as the elbow joint, enabling further extension and retraction, which adds versatility to the manipulator's movement capabilities. Collectively, these axes form the foundational structure for the robotic arm's reach and flexibility.

Understanding the configuration of these axes is essential for programming and operating FANUC robots effectively, as each joint contributes to the overall articulation and dexterity required for a variety of applications in manufacturing and automation.
