Question on speed_fr_macro

Other Parts Discussed in Thread: CONTROLSUITE

Hello!

      I am trying to use speed_fr_macro to obtain my motor speed, I have checked the angle input of the macro, which is correct, but just got very low output value, which doesn't linearly change with the change on real motor speed. I can't find any document for this macro, could you provide more info. on this macro( like what is the filter used here, how to select the coefficients) to help me debug it? Thank you!

  • Li Yang,

    The macro code and documentation can be found in the motor control library in controlSUITE. If installed at the default location, the documentation is at:
    C:\ti\controlSUITE\libs\app_libs\motor_control\math_blocks\v4.3\~Docs

    The speed_fr macro is described on pages 130 - 134.

    Regards,

    Richard
