    PWM wiring to Stepperonline T6 Series 1000W AC Servo Motor

    G'day all,
    This is my first post on this forrum (Well any forrum actualy).
    I'm upgrading my converted manual bench top mill spindle drive to a T6 rs 1000W Servo drive and are stumped on how to wire up the driver from the Mach 3 usb board using PWM . Any feedback would be much appreciated as its been a long road .
    I've attached the manuals for the Driver and the Mach 3 Motion card.

    Hi,
    I presume you have programmed the servo drive to be in velocity mode ie 0-10V?

    PS: Correction, on reading the servo manual it does not appear to have an analogue input for speed. Can you see it? It has a Velocity control mode where you send it a number
    of different digital signals and the servo selects one of the pre-programmed speeds, but it is not continuously variable.

    Is this what you intended when you bought the thing?

    Hi,
    it would appear that these servos have Pulse Control (Step/Direction) OR RS485....they DO NOT have analogue input..

    You might have gotten them cheap......but shame it won't do as you thought it would.

    Thanx for the quick respons Craig, Yes i did purchase this with the expectation of being able to control by Mach 3 as a spindle. I spose i need to get another Driver that does analogue then.

    Regards
    Heath

    Hi,
    yes, getting a drive that has an analogue input is one approach.

    Another is to use Step/Direction. This is certainly doable in Mach4 with an Ethernet Smoothstepper. I would presume you can do it in Mach3 also, but it's been so long (ten years) that
    I transitioned to Mach4 I have forgotten much about Mach3.

    If this was possible in mach 3 , then how would it work? Its always good to know all your options before deciding on a coarse to take.

    I've just looked into the easy stepper solution and it looks as though it will work on mach3 using step/dir. Its also a lot cheaper than purchasing another driver.
    Thank you so much for helping me out. :cheers:

    Hi,

    Don't know, don't care, as I have said I have not bothered with Mach3 in ten years.

    In Mach4 you can have Out-of-Band axes, which are not coordinated with regular (X,Y,Z,A,B,C) axes, and can be made to rotate freely at precise speeds.
    That is how I would do it.
