    i was disconnecting a CCU unit today in CNC milling machine and two wires disconnected from their holder. 3 holders in total.
    I was told these are connectors for x y z axis in the machine and the problem i have is i dont know what port the cables came out of as no label
    were fixed to cables. U W V is on the connector. can anyone advise me how i would chase down the correct order of connection.
    Thank you

    What is CCU?
    U.V.W. is usually reserved for power in to a controller or 3ph service supply and X.Y.Z. is the 3 phase controlled outputs to a motor etc.
    A little more info on what the CNC machine is is in order?
