When the integral value of the speed control is increased, the position response is increased and the error
magnitude of the speed control is reduced. Vibration and noise occurs easily if the gain is set to an excessive
value.

For smooth change of the speed control command, the increase in gain improves the magnitude of the following
error for the speed. For unsmooth change of the speed control command, the decrease in gain mitigates the
vibration of the mechanism during operation.
