What is a 'jog' function used for in FANUC robot programming?

The jog function in FANUC robot programming is primarily utilized for manually moving the robot in order to perform setup or adjustments. This feature allows operators to control the robot’s movements in a precise manner, enabling them to position the robot accurately prior to running automated tasks or programs. By using the jog function, users can make fine-tuned adjustments to the robot’s position, check the range of motion, and ensure that the robot is set up correctly before engaging in any production activities. This is crucial for maintaining safety and efficiency in an industrial setting, as it helps prevent errors that could arise from improper positioning.

The other functions mentioned, such as initiating the startup process, programming new tasks, or resetting the robot, serve different purposes and are not specifically related to the manual manipulation of the robot for setup or adjustments.
