The servo control inertia feed forward gain. Gain value is relative: “0” meaning no gain, “32767” meaning full gain. KK improves
acceleration control by compensating for the load inertia.
Without KK parameter, Inertia Feedforward Constant.

This parameter sets the jerk filter frequency in Hz . The lower the frequency value the more pronounced the S-curve profile will be.
Setting the value to 0 will disable the filter.
S-curve acceleration/deceleration ramps are beneficial in positioning systems where instantaneous changes in speed may cause the
load to jerk excessively. One example is when the load is connected to the motion actuator via a long movement arm. If the arm is
not sufficiently rigid, changes in speed at the actuator can result in undesirable oscillations and increased settling time at the load.
Smoothed transitions in speed changes can alleviate this unwanted motion and reduce settling time.
