  • Link to the latest Thanos AASD15A Servo Control Manual and other data sheets click here.  


Thanos Firmware Update

  • A Step-By-Step Guide on updating the Thanos firmware can be found here.



E-Stop Button Setup

  • Connect the E-Stop to the Thanos controller via an Ethernet Cable

  • For E-Stops with LEDs lights (green/yellow/red), set the #2 DIP Switch to ON which will enable the LEDs

  • Video explaining E-Stop functionality here

  • Video on Open vs Closed E-Stop Setup here

  • Video of multiple E-Stops on the AMC-AASD15A here



Actuator to THANOS port connection: 



AASD-15A Servo Settings:

Push MOD until you see Pn000. This enters the parameter mode. Change and check these settings on all motors: 

Pn8 = 300    - Max peak torque % CW

Pn9 = -300    - Max peak torque % CCW

Pn51 = 3000    - Max servomotor speed in RPM

Pn98 = 20    - Pulse Multiplier (electronics gear)

Pn109 = 1    - Smoothing (1=Fixed smoothing, 2=S-Shaped smoothing)

Pn110 = 30    - Smoothing Filter Time

Pn113 = 20    - Feedforward %

Pn114 = 10    - Feedforward Filter Time (ms)

Pn115 = 100    - Gain %

Pn24 = 100    - Torque level for home calibration

Pn52 = 1    

Pn60 = 2

Pn61 = 6

Updating the FTDI (VCP) Driver

1) Go to https://ftdichip.com/drivers/vcp-drivers/ 

2) Select the correct file for your Operating System. For Windows 10 64-bit, it would be the one highlighted below. Note: It may update in the future. 

3) Download the file

4) Extract the file by double clicking on it and moving the files to a new folder on your computer. Be sure to remember where you extract the files.

5) Go to Device Manager and select the COM port that is used for the Thanos controller. It can be any COM port, but it usually appears as 'USB Serial Port (COM8):

6) Right click on the USB Serial Port (COM8) and select 'Update driver'

7) When the window opens, select the second option to 'Browse my computer for drivers'

8) Browse your computer for the folder you extracted the driver files and choose the root folder (you don't need to select the sub-folders)

9) Click Next

10) Your FTDI (VCP) driver is now updated.


 


Electromagnetic Interference (EMI) Issues 

EMI issues on an actuator platform can manifest themselves in numerous ways. The most common are:

  • Unexpected disconnections from the Thanos controller during a race or flight which parks the platform

  • VR headsets will go gray and lose tracking or video

  • Force feedback devices will suddenly become disconnected

  • USB devices randomly disconnect

EMI issues can be a result of a number of different issues including but not limited to: 

  • EMI originating from the actuator servo drivers or motors

  • Unshielded cables

  • Power cables in close proximity to each other

  • Cables laying on top of each other rolled into tight loops creating an antenna

  • Ground loops

  • Improper grounding of the actuator servos and/or platform

  • Noise in the electrical system that does not originate from the actuator platform


How to solve EMI issues can depend greatly on your actuator platform setup; however, some solutions include: 

  • Install an EMI Filter

  • Ensure all cables are properly shielded and grounded both at the servo drivers AND the servo motors

  • Ensure the wall socket is properly grounded

  • Ensure the platform is grounded wherever electronics are mounted

  • Avoid creating a ground loop by having all electronics used by the platform share the same wall socket. This includes your PC, sim gear, monitors, and actuators. 

  • Use Ferrite Rings 

  • Keep VR cables completely away from all other cables. Using a ceiling mounted pulley system works best. 

  • Use high quality powered USB hubs

  • Use an EMI mat under the platform


EMI Filter Installation

Installing an EMI Filter is the critical first step in eliminating EMI issues in an actuator platform. Utilize the Thanos video below.

How I solved (?) the EMI problem in my SimRig

A detailed guide on how to resolve EMI issues has been created by Luis Blando which can be found here.  Additional Guide: EMI Filter Guide by John Spanos 

 



Uninterruptible Power Supply (UPS) and Actuators

If the power is cut off unexpectedly to the Thanos controller which is providing guidance to the actuator -OR- power is cut directly to the servo drivers, the servo motor is no longer able to hold the slider within the actuator in place. This will result in the actuator lowering violently which could lead to potential damage to the actuator and/or personal injury.  The Uninterruptible Power Supply (UPS) and Actuators FAQ/Guide will provide additional information on utilizing a UPS for your actuator platform can be found here

IMPORTANT: Sim Racing Studio / PT Actuator Quick Start Guide 

Follow the guidance in the SRS Quick Start Guide to get started with your platform.


Centering Platform when Parked with Double-Traction Loss 

For PT Actuator 6DOF platforms with Double-Traction Loss (ie. Full Yaw / Sway via two horizontal actuators), the Standby position within the Thanos controller must be set to 50%. Do not change the value within the Thanos controller to center the bottom of the platform.  Note: The measurements provided by PT Actuator (295mm from the edge of the bracket to the edge of the platform) may not be exactly what is needed once your platform is assembled. 


If the bottom platform is not centered when parked, you must manually reposition the Double-Traction Loss actuator brackets. Measure the distance of how far the bottom platform is out of alignment and reposition the horizontal Traction Loss actuator brackets accordingly.


Lubrication of Actuators, Linear Bearings, and Flange Mount Bearings

It is generally recommended to use Super Lube Synthetic Grease or similar NLGI Grade 2 lubricant for the internals of the actuators, linear bearings, and flange mount bearings if servicing is required.
