MMOS Direct Drive Wheel controller with DAC, plug and play with AASD servomotors

New Website for Thanos products is now here: thanos-motion.com https://www.thanos-motion.com/products/thanos-tdd-controller/ . Tindie store stock will not be available anymore; will retire this s…

What is it?

MMOS Direct Drive Wheel controller with DAC, plug and play with AASD servomotors. It comes fully assembled and programmed already with the latest MMOS firmware. The new version v2.0 includes jumpers you can cut to redirect the torque signal from the DAC directly to a pin of the STM32 if you want to try the HoanTV firmware instead of MMOS (external ST-link programmer required for this). Also added a Z axis analog input in case you want to use a analog handbrake as well, apart the standard G27 Shifter and Pedals (DB9 connectors).

Uses a ready off the shelve straight (1:1) DB25 cable to hook up the AASD servo drive. Example of recommended compatible servo: 130ST-M15015 220V 2.3KW AC Servo motor 2300W 1500RPM 15N.M. Single-Phase ac drive permanent magnet Matched Driver AASD-30A

Why did you make it?

It was made to reduce the wiring required to make TDD using the STM32 Discovery board. The inspiration to make this came from this post on xsimulator forum.

What makes it special?

I added a 12-bit DAC to convert the PWM signals from the MMOS firmware to pure 0v-3.3v voltage for the torque command, plus I added DB9 connectors to use G27 shifter and pedals (optional).

What is required from the User to setup the Servo drive

The user has to enter the following parameters in the servo drive:

PN002 = 0 (control mode - voltage mode, requires restart)
PN003 = 0 ( Servo enabled? - external)
PN018 = 0 (Take the encoder output pulse AB phase logic - 0-1)
PN051 = 1500 (Motor max RPM - see motor specs)
PN053 = 18 (SigIn 2 port functional allocation -27 - 27)
PN188 = 10 (Analog torque instruction smooth filtering time - 1-500ms)
PN189 = 100 (Analog torque instruction gain 1-300 %/V)
PN190 = -100 (Analog torque instruction offset adjustment -1.5v - 1.5v)
PN191 = 0 (Simulation of torque command direction - try 0 first)
PN198 = 500 (Torque control speed limit - 0-4500rpm)

Enclosure for it?

Sure, download the STL files on Thingiverse

Great Alternative to Other Direct Drive Systems

Was looking for a cheaper alternative to Direct Drive and belt-driven racing wheels when I came across this board and the forum page. I decided to take a chance and try this board. I was not disappointed! In fact, I was more than impressed! I've been using the motor for months now and have put over 100 hours into it which no issues. The setup was easy and the board offers a lot of customization. I even stupidly damaged the micro USB port and I was able to work around it with help from the awesome community around the board. Great product and would recommend to anyone wanting a DD wheel who isn't afraid of a little DIY.

Board received, not installed yet, but...

Hello,
I was following the Thanos boards, and intended to buy the 6DOF controller. Then i stumbled on this great little board in order to make a quite simple OSW wheel.
I ordered the board, ordered all other parts, and im waiting to arrive.
My TDD board got lost at the postal service, and without hesitation, Thanos send me a replacement board.
This is Service witha a capital "S" !! I really love this, and it gives a very good faith in this seller.
Now, the board arrived after all, and the replacement is on its way. I made an arrangement with this seller, as i do not want 2 boards for the price of one!

Board looks well made, but theres no description, manual or something like this, so you really need to get it all from the online information. (which is more than sufficient by the way).

Even though im not able to test yet, i give this setter a A+ without hesitation!
