Which axes are classified as the minor axes in the FANUC system?

In the FANUC system, minor axes are typically those that are not primarily responsible for the main movements of the machine but rather assist in achieving more complex motions needed for precise control. The classification of axes into major and minor categories helps in understanding their functions better in applications like robotics and CNC machining.

In this context, J4, J5, and J6 are considered the minor axes because they typically handle supplementary movements that contribute to the end effector's orientation or positioning without altering the primary pathway defined by the major axes (which are often J1, J2, and J3). This allows more intricate and flexible movements during operations, such as enabling rotation or tilt while the major axes handle the primary linear motion.

Understanding the classification of axes helps in programming and operating FANUC systems effectively, as it allows for optimized configuration of motions based on the task requirements.
