 This parameter is valid when Pr.11-00 bit0=1.
 Increase Pr.11-12 to reduce the error of command tracking, and improve the speed transient
response. It is applicable for speed command tracking.
 Set Pr.11-01 correctly to get excellent improvement of the speed response.

PDFF Gain Value
Default: 30
Settings 0–200%
 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.
