AASD Servo Drive Parameter Configuration and Calibration - hoantv/CarSimulatorFirmware GitHub Wiki

At this point you should have wired up your servo drive, the motor and the controller board (the STM32 board or a TDD board).

Don’t power on your STM32 or TDD board yet.

Follow these steps to setup the parameters of the AASD servo drive:

  1. Engage the Estop button (press it in to ensure the motor is disengaged).
  2. Power on the AASD servo drive.
  3. Don’t plug in the controller board yet.
  4. Set all the parameters on the AASD servo drive to the Initial Values in the Parameters table.
  5. Display the current reference voltage of the servo drive using the Dn017 feature. This the “resting torque command voltage”. Take note of this number (i.e. 0.07).
  6. Reset the reference voltage of the AASD servo drive by doing the following: a. Unplug the DB25 cable from the servo drive. b. Run a short piece of wire between pins 13 and 25 to short the pins. c. Run the Fn007 function on the servo drive (see page 34 of the user manual).
  7. The parameter Pn190 is automatically updated to the correct offset for your drive’s “resting torque command voltage”. The value from Dn017 is multiplied by -10. For example, if Dn017 shows 0.07, your Pn190 should now be set to -70. This should happen automatically.
  8. Start the VNM Wheel Configurator app on your PC.
  9. Plug the controller into the PC via the micro USB port.
  10. Ensure that the Status of the VNM Wheel Configurator app changes from “Disconnected” to “Connected”.
  11. Follow the Initial Config of the VNM Wheel Configurator (Windows App) to configure the firmware.
