I cannot understand the function of the Value Graph. This is a spinning wheel.

The value graph shows an increase in value, then the value stops, then goes the other way. If the value graph is going up, the rotation is moving clockwise; if the value graph is going down, the rotation is moving counterclockwise. There's nothing wrong. You are just looking at the wrong graph. You should be editing the speed graph, not the value graph. 

 

Rotation and Position changes also interact with the frame rate. The motion will stop if rotation is in sync with the frame rate. You cannot

Rotation and Position changes also interact with the frame rate. The motion will stop if rotation is in sync with the frame rate. You cannot just speed up rotation and then slow it down without risking the stroboscopic effect making the wheel look like it is speeding up, changing direction, and changing direction again. 

 

Dan Ebberts has an expression that will overcome the changing direction problem, but you still have to worry about the stroboscopic effect as the wheel accelerates. You will find it here: Frequency and RPM Control.
