Set the load inertia ratio to the motor rotation inertia by %.
Inertia rate = load inertia/ motor rotation inertia x 100
Load inertia rate is a very important control variable for the servo operation
characteristics. The inertia ratio should be accurately set to achieve optimal servo
operation. The inertial ratio can be estimated by automatic gain tuning. Real-time gain
tuning will estimate the inertia continuously during operation.

Set the overall responsivity of the position controller. Responsivity increases as the set
value increases. Too high responsivity may cause vibration depending on the load.

Set the overall responsivity of the speed controller. Increase the overall system
responsivity, both position loop gain and speed loop gain should be set high. Too high
responsivity may cause vibration depending on the load.

Set the integral time constant of the speed controller. Higher value decreases the error
under the steady state (stop or operation at regular speed). However, excessive state
(acceleration/deceleration) may cause vibration.
