This corresponds with the "Model Filenames" section. This setting uses the numbers -1 to 18 and determines which model is used. If no models are used, this number should be set to -1, otherwise from 0 to 18. In this case you want the number corresponding with the spinner prm.

These numbers range from 0 to 1. This is the axis (X,Y, or Z) on which the spinner model should rotate. It is possible to combine 2 or 3 axis to achieve unique angles.

Numbers less than 1 or greater than 1 will cause the model to be scaled to that size when turning. An input of 2 will cause the spinner to not only rotate, but at full rotation, become twice it's original size. An input of 0.5 will cause the model, at full rotation, to be scaled to half of it's original size.

This is the velocity (or speed) of the spinner rotation. A value of 1 means that the spinner will spin once in 1 second. A value of 2 means 2 rotations in one second, and so forth. A negative value will make the spinner spin in the opposite direction.
