Sorry, I thought the table formatting would work to clarify the values but it didn't

Thanks, perhaps I have not explained my question or perhaps it's just not possible.  To try and clarify, let's say I create a time cam (MATC) where the Master value is time and the Slave value is a rotary angle on my rotary axis.  Let's say the values I need in the cam are: <table> <tr> <td>Master</td><td>Slave</td> </tr> <tr> <td>0</td><td>320</td> </tr> <tr> <td>10</td><td>350</td> </tr> <tr> <td>20</td><td>10</td> </tr> <tr> <td>30</td><td>30</td> </tr> </table> To get to 10 degrees, I'd rather have the rotary motion continue in the same direction, crossing the 360/0 boundary.  Imagine if it was a physical cam, you would continue rotating in the same direction to get to the 10 degree position from 350 degree position rather than moving 340 degrees all the way backwards to the 10 degree position. It occurred to me that I could change the unwind parameter so that I can specify and therefore rotate to angles over 360 degrees but that requires me to do more calculation in my code which creates the angles which are used to generate the cam via MCCP. Does this make more sense ?

If I use a Motion Axis Move (MAM) command on a rotary axis, I can specify "Move Type" to be "Rotary Shortest Path", which will allow me to get from say 350 degrees to 10 degrees by the shortest route, i.e. move 20 degrees rather than by moving 340 degrees. I want to have the same behaviour in a CAM function but I can't work out how to achieve that - MATC accepts the angles but rather than move the shortest path, it takes the absolute path in a positive or negative direction.  Is there a way to achieve "Rotary Shortest Path" in a CAM?
