Inventor Studio Rotation

I'm trying to animate rotation of pulleys by using the angle constraint and it works for 2 pulleys but won't allow me to rotate any of them beyond 360 degrees. Is this supposed to happen? Does inventor only allow 360 degrees of rotation in inventor studios? Is there a way I can get passed this besides creating a second animation for both to carry on beyond the 360 degrees? 

 

Is it possible to animate a rotation constraint? I originally used the rotation constraint to set a ratio between a compound pulley train. For some reason I can use the angle constraints to animate 2 of the 3 pulleys but when I try to rotate the third one it gives me an error. I've screenshot the error message. I've also included a photo of a compound pulley train similar to what i'm using because i can't share screenshots of the model i'm using. 

 

Example of what i'm trying to accomplish:

First pulley is a 22 tooth connected to a 16 tooth (second pulley)

Third pulley is a 20 tooth connected to an 84 tooth (fourth pulley)

 

I don't require the second pulley to rotate as it sits on the same shaft as the third and it isn't seen in the animation i'm producing. 

 

As far as rotation goes I need the 84 tooth to rotate 114°, the 20/16 tooth to rotate 479°, and the 22 tooth to rotate 348°. It lets me add the animation to the 84 and the 22 tooth, but even if I add a 360° or less rotation to the 20/16 tooth it gives me the error. None of the pulleys are attached to each other except by the rotation constraint I added but this isn't the problem as I've deleted them to test. Any ideas? Sorry for the lack of supporting information.

There is no limit.  If the motion is valid in the real word - it can be made to work in Inventor.

Attach your assembly here.

Unfortunately i'm not allowed to attach any files for legal reasons.

Can you make up a dummy assembly that exhibits the same behavior?
