Chapter 7 Adjustments
7.1 Overview
The servo drive needs to make the motor faithfully operate in accordance with the instructions
issued by the upper controller without delay as much as possible. In order to make the motor
action closer to the instruction and maximize the mechanical performance, gain adjustment is
required. The process of gain adjustment is shown in Figure 7-1.
Figure 7-1 Gain adjustment process
The servo gain is composed of multiple sets of parameters such as position loop, speed loop, filter,
load inertia ratio, etc., and they affect each other. In the process of setting the servo gain, the
balance between the setting values of each parameter must be considered.
Before adjusting the gain, it is recommended to perform a jog trial run first to ensure that
the servo motor can operate normally!
