Typically, you design a motion (with MotionDesigner) for a Tool/EndEffector. Then, typically, you add more parts, which you join to the ToolPart, to create a more complex kinematicchain. Finally, you use a servomotor to drive a part in the kinematicchain, that has a different motion to the ToolPart. To plot the motion for the servomotor you can use a Measurement FB, add a Graph FB, and then export a list of positional datapoints for the servocontroller. While this is frequently satisfactory, it is preferable to export to the servocontroller a series of polynomials rather than a list of datapoints. The output from the Polynomial Fit FB is the bestfit motion to the data at its inputconnector, but defined as a series of 5th order Polynomials. You can export the Polynomials directly to MotionDesigner. In MotionDesigner, you can further manipulate the Polynomials, as required.
