11 -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.
11 +The servo gains are composed of multiple parameter sets, including position loop gain, speed loop gain, filter coefficients, and load inertia ratio. These gains affect each other, requiring balanced adjustment of all parameter values during servo tuning."
