Inertia and tuning servo loop gains
A system is always as controllable as the control loops are tuned. To reach the desired performance for the application must be reconciled with the inertia ratios of motor and load.
To understand inertia relationships, it helps to look at the stiffness of couplings and how it affects the application. Then, a load is not always coupled, but rigidly connected. Simple calculations can help to understand the situation.
