During the automatic load inertia recognition process, if vibration occurs, the load
inertia identification should be stopped immediately;

7.3 Gain adjustment
In order to optimize the responsiveness of the servo drive, the servo gain set in the servo drive
needs to be adjusted. Servo gain needs to set multiple parameter combinations, which will affect
each other. Therefore, the adjustment of servo gain must consider the relationship between each
parameter.
Under normal circumstances, high-rigidity machinery can improve the response performance by
increasing the servo gain. But for machines with lower rigidity, when the servo gain is increased,
vibration may occur, and then affects the increase in gain. Therefore, selecting appropriate servo
gain parameters can achieve higher response and stable performance.
The servo supports automatic gain adjustment and manual gain adjustment. It is recommended to
use automatic gain adjustment first.
7.3.1 Automatic gain adjustment
Automatic gain adjustment means that through the rigidity level selection function [P03-02], the
servo drive will automatically generate a set of matching gain parameters to meet the
requirements of rapidity and stability.
