Chapter 9 Tuning
9.1 Overview
9.1.1 Basic Conception
Tuning is a process of satisfying the Servo performance by adjusting the Servo parameters. The key is to
grasp the adjustment method of the Servo parameters and correctly evaluate the Servo performance.
Tuning Flow
Tuning is is usually an iterative process, and Figure 9-1 shows the general flow.

Parameter Classification
There are two types of parameters in the tuning.
 Function Parameters: refers to some application function selections or switches that may improve
Servo performance.
 Adjustment Parameters: increasing or decreasing these parameters may improve Servo performance.
Servo Performance
In general, the indicators used to evaluate Servo performance are bandwidth, response time, overshoot,
steady state error, anti-load disturbance, speed ripple fluctuation, torque ripple, and so on. Table 9-1
shows the comparison of the graphics before and after tuning in the example indicators.
