Problem in motion study - crankshaft

Goodeverning everybody,

 

I want to plot a graph in which the x-axis represents crankshaft rotation (in degrees) and on a y-axis the displacement of the small end(in mm's). I have set up a motion study but I get some strange results. In the screenshot below you can see how I have set-up the analysis. Below this screenshot a result plot. As you can see the crank angle is not correct, it should start at -180 degrees till +180 degrees. This because I have added a motor which makes one rotation. Can anyone tell me what is wrong in my model?

Thank  you very much in advance,

 

Kind regards,

 

Peter
