The load inertia can be calculated by the settings of motor parameter, Pr.11-02 Sheave Diameter, Pr.11-14 Motor Current at Accel. and Pr.11-15 Elevator Acceleration. This parameter can be used to adjust inertia ratio of load.

After estimating inertia and set Pr.11-00=1 (auto tuning), user can adjust parameters Pr.11-06, 11-07 and 11-08 separately by speed response. The larger number you set, the faster response you will get. Pr.10-08 is the switch frequency for low-speed/high-speed bandwidth.
