adding speed to geared axis in MCC

Which is the best way to add a speed component (from feedback) to an axis that is geared to another? The speed feedback component is calculated in a ST program but I want to add this component to the axis in the MCC chart. Is "Start axis position-controlled" with transition behavior "superimpose" inside a "while" correct? (See image below). Or is it going to keep adding one feedback speed over the other?

Superimposed motions are independent motions. Superimposed motions cancel each other. Superimposed motions can be stopped and continued separately. Superimposed motions on a position axis are executed in the superimposed axis coordinate. 3.13.10 Superimposed positioning Superimposed positioning is performed in the superimposed coordinate system of the axis. The target position can be specified as an absolute or relative position in this coordinate system. (For feedback of the target position, see Superimposed motion) The superimposed motion has its own programmable dynamic response parameters. The userDefault settings of the dynamic response parameters are identical to the settings of the main motion. Blending conditions for the superimposed motion are ignored.
