11.3.4 Damping gain (KV)
As the motor load inertia increases, the servo system will require higher damping gain (KV) to reduce position errors during
constant speed and when the motor stops.
When KV is too small, this low damping value will cause large position error fluctuations while the motor is running at constant
velocity and while stopped, holding position. As the next chart shows, an increasing amount of position error occurs during constant
velocity and when stopped. These oscillations seen on the graph will result in motor and system vibration, as well as audible noise.
As seen below show, the position error is reduced as KV increases.
KV=10000 KV=16000
