<p>VELOCITY COMMAND SIGNAL GENERATING APPARATUS Apparatus for generating a velocity command signal representing a predetermined optimum velocity of movement of a selected one of a plurality of movable elements from its actual position to a desired stopping position. The apparatus comprises means responsive to a first signal representative of the distance to be traveled by the selected movable element from its actual position to a desired stopping position for generating a second signal proportional to a predetermined optimum velocity of movement for each of the plurality or movable elements when required to be moved a distance represented by the first signal. A plurality of multiplication means are respectively associated with the plurality of movable elements, each multiplication means being coupled to the means for generating a second signal and being capable when enabled of multiplying the second signal by a constant representative of the particular motion characteristics of the associated movable element in order to form a velocity command signal representing the predetermined optimum velocity of movement for the associated movable element. The apparatus also comprises means coupled to each of the plurality of multiplication means and responsive to a third signal representative of the selection of the selected movable element for enabling the multiplication means associated with the selected movable element.</p> |
