This parameter is used to set the feed forward gain when executing speed control command. When using speed smooth command, increase gain can improve speed track deviation.

When not using speed smooth command, decrease gain can improve the resonance condition of mechanical system.

In theory, stepping response can be used to explain proportional gain (KVP), integral gain (KVI) and feed forward gain (SFG). Now we use frequency area and time area respectively to explain the logic.
