Teaching of FANUC industrial robots is a teaching method using a tool called a teaching pendant. There is a button on the teaching pendant that describes the operating direction of each axis, and you can operate it by using it. The feature is that teaching is performed using a function called a register. The register function is a function that registers a certain position as a reference and allows you to register points simply by entering a numerical value indicating how far the XYZ (up / down / left / right) direction is from that reference point to the next point. The advantage of this function is that it is highly suitable for the teaching “offline teaching” function on the PC. It is possible to create an accurate teaching program on a PC and reduce the work man-hours on site.
