8.1
Overview and Flow of Tuning
Tuning is performed to optimize response by adjusting the servo gains in the SERVOPACK.
The servo gains are set using a combination of parameters, such as parameters for the speed
loop gain, position loop gain, filters, friction compensation, and moment of inertia ratio. These
parameters influence each other, so you must consider the balance between them.
The servo gains are set to stable settings by default. Use the various tuning functions to
increase the response even further for the conditions of your machine.
The basic tuning procedure is shown in the following flowchart. Make suitable adjustments
considering the conditions and operating requirements of your machine.
