    I am working on a cnc table build for my plasma machine. Certain things need to be done with extra care in regards to EMI..

    I want to know the immunity of PWM signals over a cat 5 wire no longer than

    Why would you expect them to have any particular kind of immunity?
    The pairs are twisted, but not shielded. What does that tell you?

    "cables no longer than..." No longer than what?

    As one may infer from Papabravo's rhetorical question, perhaps a twisted-shielded pair would be more appropriate than CAT 5. Since you have not done this before and might not have an example to follow do not be surprised if noise sneaks in by unanticipated paths.
