As the image describes, the Feedforward refers to the generated profiles (Velocity Trajectory(136), Position Trajectory(140))
Thinking of what you are inquirying, you are looking the way of finding proper gains by referencing other data, I guess.
Make sure that internal controller gains should be determined by using experiment approach.

For a XM540 in position controller mode, could I get an explanation of how the first feedforward term is calculated (Referring to the block diagram at 2.4.25 at https://emanual.robotis.com/docs/en/dxl/x/xl430-w250/)? Is the feedforward based on the present motor position and goal position or does it use the previous goal position and the new incoming goal position to calculate a feedforward velocity?
