6 Gain Tuning
6 Gain Tuning
6.1 Overview
Set the gain parameters of the servo drive to proper values so that the servo drive can drive the motor as
quick and accurate as possible based on internal references or commands sent from the host controller.

Example of gain settings
The gain is defined by the combination of multiple mutually-affected parameters (including position loop
gain, speed loop gain, filter and inertia ratio). Set these parameters to proper values to keep a balanced
performance.
NOTE
Perform a trial run through jogging before gain tuning to ensure the motor can work normally.
The following figure shows the general process of gain tuning.
Start
Inertia auto-
tuning
Gain
auto-tuning
Manual gain
tuning
End
Use offline or online inertia
auto-tuning. See Chapter 6.2
for details.
If gain auto-tuning cannot
fulfill the application needs
,
perform manual gain tuning.
See Chapter 6.5 for details.
Vibration
suppression
See Chapter 6.3 for details on
gain auto-tuning.
