Raul,

Zero Rotation is the Pick & Place machine Zero Rotation. So you want to build your library parts in the same rotation as the Zero Rotation as the assembly machine tape and reel or tube.

See the attached document for the standard part Zero Rotations. This information was provided by JEDEC in the JEP95 publication.
