(*2) Dumping attribute refers to the oscillation generated at the time of stepping. The larger the attribute, the greater the vibration. By making the dumping time short, vibration convergence becomes faster, which shortens the set's waiting time, and thus stabilizes the operation. Also, the current application time is shortened to realize low current consumption.
