As far as I understand, this is a followspot manually driven by a lighting technician, thus there are no DMX channels available on it's profile to control the move. A workaround could be to add DMX rotators to the fxiture and once patched, you can control the fixtures movement with a console.
In this link, you may find a short video tutorial on motion control.

Wow, exactly what I was looking for ! Sorry for my question, it was in tutorial videos and I watched it but before buying, many times before buying !

Thanks, that helps.
