Translation for "home" in context of machine positioning

I'm translating software used to control a machine. One of the buttons in the software is labelled "home" which brings the machine to it's reference or home position. I'd like to find a find a short, single word (if possible) in Spanish for this button. My translator is stumped on this one. I've come up with "Secuencia de referencia" via Google Translate, but I don't know if that is the most appropriate and it is longer than I'd like. Any suggestions?

Thanks

Hi there!

The usual translation is "Inicio".
