 You can calculate the load inertia according to the settings of motor parameters, Pr.00-45 Motor
Current at Acceleration and Pr.00-46 Carriage Acceleration. You can use this parameter to
adjust the mechanical inertia ratio.

 After estimating the inertia and setting Pr.03-90 =1 (auto-tuning), you can adjust parameters
Pr.03-12, Pr.03-13 and Pr.03-14 separately by speed response. The larger the value, the faster
the response. Pr.03-91 is the switch frequency between the low speed and high speed
bandwidth.
