3-7-1 Auto-tuning
Auto-tuning rotates the Servomotor with a load connected (mechanical system), and au-
tomatically adjusts the position loop gain, the speed loop gain, and the speed loop in-
tegration time constant. When adjustments cannot be made by auto-tuning, refer to
3-7-2 Manually Adjusting Gain.
