FF (feed-forward) gain
Axis-specific parameter number Unit Input range Default value (reference)
61 - 0 to 500 0
This parameter sets the FF (feed-forward) gain of the position control system.
Setting this parameter increases the servo gain and improves the response of the position control loop.
Use this parameter if you want to improve the response of the mechanical system whose mechanical rigidity is
low or load inertia ratio is high.
A reference range is 10 to 50. Increasing the value set in this parameter decreases the deviation and improves
the response.
Note that setting a large value may generate vibration or noise.
