What is it?

The controller was built to control AASD15 and similar servo output stages. All controls with step dir can be operated. the AASD15 servomotors are inexpensive servomotors mostly from china, which are used in motion platforms for car races and flight simulation or roller coaster

The control board is delivered fully assembled for the connection of 7 motors.

There are purchase options for the handheld device as a set to assemble yourself or as a finished device. There is also the option to buy the control board with display and encoder. No hand-held device is required, but at least 1 additional switch is required for operation with no handheld. Screw connections for this are available on the board.

Why did you make it?

The controller has been developed for controlling servomotors in motion platforms. I developed this because there was no one on the market that controls the movements of the motors so finely that a flight-like movement emerges.

What makes it special?

Hardware functions

1. Control of 6 + 1 servo motors (7. is not tested actually)
2. Pulse speed up to 550 kHz
3. Step / Dir Mode
4. Query and evaluation of torque (for calibration) and error status
5. Display of parameters via LC display 16x2, full menu
6. Operation via rotary encoder with push button
7. Switch for signal reception
8. Emergency stop switch for the servo functions
9. Serial USB connection for data transfer
10. 32 bit processor
11. Saving the settings to EEPROM
12. LEDs for status and display (external handheld)
13. Housing (to print yourself)
14. optional Handheld device ca be installed 3m away with DB25 cable (optional)
15. LC display and encoder can also be installed on the mainboard
16. Automatic home calibration on power up or re-connection without limit switches
17. Limit switches can be optionally installed for home calibration
18. Protection from exceeding physical limits of the actuator
19. Platform Health check, to ensure all actuators are ready and active
20. Latency as low as 1ms in Mover and Simtools or faster if some tool will support
21. E-stop, Force Offline buttons and switches (Handheld or onboard connectors)
22. USB powered

Software functions

1. Software is menu-driven and easy to use
2. Completely adjustable for your own requirements
3. Monitoring the status of the motors
4. Automatic calibration of the servomotors
5. Service function for repairing or checking the sim rig (moving)
6. Manual moving of each motor individually for testing
7. Adjustable direction for inline or foldback placement of servomotor
8. Screw lead pitch, 4mm, 5mm, 10mm,25mm or other advance per revolution free adjustable
9. Adjustable stroke unlimited
10. Selection of belt reduction ratios or gear ratios freely adjustable
11. Rotating and linear actuators are supported
12. Scaling the output signals (master gain)
13. Real exponential moving average filter for anti-vibration and smooth pulses on the servomotor
14. Advanced full adjustable spike filter to automatically eliminate jolts during crashes or unwanted motion cues
15. Offset value for each motor (especially for rotating actuators)
16. Actuator parking can be set individually.
17. Speeds for calibration, slow speed and high speed freely adjustable (max. 550 kHz)
18. Inverse kinematics: 19.1. 1000 calculations per second (for linear and non-linear actuators ...w.i.p.) 19.2. Geometry for steward platforms with 6 DOF and 6 actuators individually adjustable 19.3. linear timebased Wash-out filter for each axis (adjustable)
19. Evaluation of 24-bit input data (Simtools / Mover)
20. Calculation in 32/64 bit for maximum smoothness of movement
21. 2 different operating modes: direct or inverse kinematics
22. real 24 bit resolution of the actuators
23. regular software Updates possible

the handheld device is delivered without a db24 connection cable. 3-5 meters are tested to work. you need male cable on both sides
