    Fanuc 0TD Phase sequence - if I get it wrong what happens?

    Hi I have a new lathe Fanuc 0-TD controller. As title suggests, if I flick the on switch and the phase sequence is wrong could I destroy the machine?

    I was going to turn on the mains power briefly, check the coolant pump rotation, and reverse if need be.

    Normally the machine will not power up if the phase rotation is wrong, until corrected.
    But IIRC the 0 controller itself does not require correct phase rotation as the earlier systems do.
    Only the 3ph motors external to the system.
