6 Servo gain adjustment
6.1 Overview of servo gain adjustment
6.1.1 Overview and process
Servo drivers need to drive motors as quickly and accurately as possible to track instructions from the
host computer or internal settings. In order to meet this requirement, the servo gain must be adjusted
reasonably.
The output value of servo gain is in adaptive mode, but different machines have different requirements
for servo responsiveness. The following figure is the basic process of gain adjustment. Please adjust
according to the current state and operation conditions of the machine.
