    AC power does not use positive and negative.

    RM - but a SMPS puts out DC you need an AC output. You need a 20-80V AC power source. Put up an image of the output of the SMPS....Peter

    Yes, you have a DC power supply, and a drive that requires AC power.

    A DC power supply (30 to 110VDC) will work too, according to the manual. As long as it has enough power.

    COD - Can you show image of where in manual it says DC is OK? Why do they say AC when they could have said AC/DC??? Found it but does seem odd.... Peter

    it mentions it in 3 places but does not say which polarity to use so maybe does not matter???

    Polarity does not matter. Input power goes to a diode bridge inside the servo, so you can connect "+" and "-" whichever way you like.

    I'd buy a toroidal AC supply. Something like a dual output 40v unit and wire it in series to output 80v AC.
    A 60v DC might be a dissapointment.

    Such as:

    Or for a powerful system:

    As no one else has mentioned it - that is a SERVO driver and you have said you are using STEPPERS with encoders elsewhere ? ? ? Servos maybe AC powered - steppers are most certainly DC powered and polarity connections will be important yo ensure rotation direction is as commanded and not reversed!

    We are talking about the power supply connection, not the motor connection. AC/DC power has nothing to do with the motor type, it depends on whether the driver has a built-in rectifier. This particular one does, so it can be powered with either AC or DC.
