Motors, acceleration and DOF

I'm a relatively new user of SW Motion Analysis (Engineering Student) and have run into a few issues while working on an assignment.

The teacher for this course went over how to use SW Motion Analysis briefly, but didn't cover some of these aspects;


1) How to include acceleration/decceleration when applying a rotary motor. The assignment is an analysis of a 4-bar mechanism, wherein the driving link is rotating at a given speed (rpm) and is deccelerating at a given rate (rad/s^2). I've added the rotary motor to the analysis, but I have no idea how to incorporate the decceleration.


2) Degrees of Freedome. This might be an interpretation issue, but the assignment asks for "a screen shot of the DOF dialog box with explanation of why the DOF suppressed by the software do not affect your results."  I have not been able to find any information regarding a "DOF dialog box" anywhere; could anyone provide any insight into this?


Any information regarding these issues would be greatly appreciated.
