    I have started a Direct Drive wheel using the Thanos TDD board

    I have ordered a 2500 ppr 130st-15015 servo motor and driver direct from mige

    It has 30nm potential and run at less power it should not get hot.

    I will post progress on this thread as the parts come in.

    I am looking for a hub adaptor and frame to mount the motor if anyone has any suggestions

    Today the mige servo motor arrived

    The drive appears different to the one Thanos uses, i think it operates the same.

    Unfortunately the TDD board is held up in Los Angeles and itnhas been delayed

    I have fitted an old kart wheel for now

    I took a 19mm dia wheel hub and bored it out to 22mm.

    A quick polish up on the lathe and the hub adaptor looks good.

    I hope the TDD turns up soon so i can get testing

    Hmm. Not sure at all how you can use the Mige Servo drive. Certainly its not plug and play to the TDD as the AASD-30A Servo drive is!!

    Do you have the Mige manual perhaps?

    I asked for the exact AASD-30A - this is what they sent

    do Mige not make the AASD-30A ??

    I have a copy of the manual - will scan it

    Attached is the pin comnections

    Are they the same as the AASD ?

    Through my questions with Mige I found that no they do not make or supply AASD servos. They have two servo models called MG1000C and DS100S-75.

    The DS100S manual is already on xsim:
    https://www.xsimulator.net/community/attachments/ds100s-manual-pdf.57591/

    and Mige sent me the MG1000C manual.

    When I asked what are the differences between the drives they said:
    "There is no main difference between the DS100S-75 and the MG1000c-30L.

    There are just two different model."

    does your driver look the same as mine ?

    do you use it for a DD wheel ?

    it seems likely i can use this with the TDD board if the wiring is the same, or i can wire the connector to suit

    it looks like i have the DS200

    seems like a nicely built unit

    manual uploaded :)

    I did not buy the mige drivers, I bought AASD drivers from another vendor.

    I agree that you will probably be able to wire the connector to suit.

    Yes, the custom wiring is one problem solved, but what about the torque parameters? I'm not sure if they are the same or if similar ones exist in the Mige servo drive and with what values...

    It shows a 26pin connector... not the same as the DB25 of the AASD servos

    Oh, and the Torque signal is two pins Positive and Negative. It doesn't seem to use a single analog Torque signal input with digital direction pin like the AASD...

    reminds me of the different control strategies used for DC motor controllers - some use 2 pwm pins for cw and ccw - some have a pwm pin and a direction pin

    so I need to understand what the TDD board exactly does and how the code works

    option 14 allows you edit the type of control :)

    "1.Set the mode position command pulse.
    2. To set one of input modes through parameters:
    0: Pulse+Direction

    1: CCW pulse/CW pulse
    2: phase A and phase B quadrature pulse input.

    Remark: CCW: observe from the motor axial direction. It defines CCW in counter clock wise and CW in clock wise

    there is a gain / amplifier for the torque

    the default is 30%
    range from 10% to 100%

    The TDD works exactly same as MMOS... but instead of PWM/DIR it outputs Analog/DIR signals

    The latest 86 page manual attached

    It seems there is a filtering/smoothing function and it may work without a DAC

    The more I read the more it seems a nice solution, it is what mige recommend for thier motors
