Answer analysis:
In the MoveJp3 instruction, V500 represents the speed at which the robot moves, usually in millimeters per second (mm/s).
This speed value is the speed at which the robot moves along the path, ensures that the robot moves accurately according to the specified path, and can be fine-tuned without affecting the speed.
In the instruction above, setting the V500 to 500 mm/s means that the robot will move to the next point at this speed.
