Make an Itween Event move contantly?

[Avascar]

Hi, I'm creating a constantly moving platform. I don't want to make Itween events loop because the results are twitchy, so I want a never-ending event. Although I'm a bit stuck at this, what event should I use and at what settings?

I'm moving a platform at a certain constant linear speed along the x-axis.

Try the iTween Move Update actions

I attempted to do this, but once it finishes its vector position it moves very slowly.
