How to fix rotational angle for oscillating 2D box in dynamic mesh

I am beginner to learn dynamic mesh model. i have model simple 2D box and my purpose is to rotate small box inside the big one in anticlockwise direction and rotation is to be limited to 30 degree.
I have made use of udf for angular velocity for box as shown in below image, I have put simple formula as omega(2)=theta/time=(30*pi)/(2*180) where time is 2 sec.
but as number of time step increases from 1000 to 10000 the rotation continues in CCK direction but i need only 30 degree then how to stop the continuous rotation of block.
Is there need to change udf, if anyone tried please help me out..!!!
Thanks in advanched
