CCS/TMS320F28026F: Automotive 48V 1kW Motor Drive Reference Design TIDA-00281

Part Number: TMS320F28026F
Other Parts Discussed in Thread: TIDA-00281

Tool/software: Code Composer Studio

I'm working on BLDC motor controllers.I saw TIDA-00281 48V BLDC referance desing.I want to work on it but I couldn't understand how can we setting its speed or its forward and reverse settings.

I couldn't see any potensiometer or something like that and any button for its forward and reverse settings.Is that all software settings. If I want to add a potensiometer and a button is that possible and if its possible how can I do that.

 

Thank you,

Best regards.

  • On page 40 of the TIDA-00281 reference guide, it explains how to change the motor speed:

    Step 10: To change the commanded speed, click on the value field of SpeedRef_krpm and enter a new value (in kRPM).

    To change the acceleration, click on the value field of MaxAccel_krpmps and enter a new value (in kRPM per second).

    Note that the speed reference can be either positive or negative, affecting whether the motor rotation is clockwise or

    counterclockwise.

     

    If you want to add a potentiometer, you would need to add also software to read the value of the potentiometer (into TMS320's ADC) and use that for a speed command.  This is beyond the scope of the TIDA-00281 reference design.
