 This function enables when Pr. 11-00 bit0 = 1.
 Increase the setting for Pr.11-12 to redcue the command tracking difference, and improve the
speed response. Use this function for speed tracking applications.
 Set Pr.11-01 correctly to get excellent improvement of the speed response.

 This parameter is invalid when Pr. 05-24 = 1.
 This parameter is valid only when Pr. 11-00 bit0 = 1.
 After you finish estimating and set Pr. 11-00 bit0=1 (auto-tuning), use Pr. 11-13 to reduce
overshoot, but a shift of the curve may occur earlier. Set Pr. 11-13 = 0, when the acceleration
time fits the applicable demand, but an overshoot occurs, increase Pr. 11-13 to "the best
acceleration without overshoot".
 Increase Pr. 11-13 to improve the overshoot of speed tracking, but an excessive value may
reduce the transient response.
 Increase Pr. 11-13 to enhance the system stiffness in high-speed steady state, and reduce the
speed transient fluctuation at suddenly loading.
