Are you talking about boundary conditions? Why not just set the vector components?

They are Euler angles. It depends on the rotation convention you define, but they correspond to angles about the cartesian axes. I assume you are familar with Euler angles, no? Check out the help docs on the subject, they should clear things up for you.
