Pr0.04=( load inertia/motor rotational inertia)×100
%
Notice:
Set inertia ratio according to actual load inertia. When both are uniform, actual motor velocity loop
responsiveness and gain settings will be consistent. If inertia ratio is greater than actual value,
velocity loop gain settings will be higher and vice versa.
