Use the model following control
and load oscillation suppression.
To use the Model Following Control properly, you shall adjust the relevant parameters in the order of
Torque Loop → Speed Loop → Position Loop → Model Following Control.
For details on the relevant parameter of Torque Loop, Speed Loop and Position Loop, refers to the section
9.2.3 Manual Tuning. The relevant parameters of Model Following Control are as follows.

The Model Following Control Gain (Pn151) determines the position response performance, and increase
this setting can improve speed of response, but overshooting will be likely to occur.
The Model Following Control Gain Correction (Pn152) determines the damping ratio, and increase this
setting can also increase the damping ratio.
The (speed/torque) feedforward in Model Following Control is a percentage factor that is used to adjust
the output feedforward.
