I bought a S12ZVML128EVB, and the BLDC is not from Freescale. I had download the software MC9S12ZVML128_BLDC_Sensorless, but it can't rotate the motor. Where to set the parameters? I can't find the motor parammeters in software.</P></BODY></HTML> Thu, 05 May 2016 23:49:18 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Parammeters-setting-about-S12ZVM128EVB/m-p/502986#M12315 zoujiahao 2016-05-05T23:49:18Z Re: Parammeters setting about S12ZVM128EVB https://community.nxp.com/t5/S12-MagniV-Microcontrollers/Parammeters-setting-about-S12ZVM128EVB/m-p/502987#M12316 <HTML><HEAD></HEAD><BODY><P>Hi zoujiahao,</P><P>Could you please specify parameters of your BLDC motor?</P><P>In fact, the MC9S12ZVML128_BLDC_Sensorless code has all settings directly inside MC9S12ZVML128_BLDC_Sensorless.c file.</P><P>The S12ZVML128EVB board contains the SW3 switch (ON/OFF) which drive motor control code. Is this switch in the correct position?</P><P>Please check also default jumper positions on your board.</P><P></P><P>It would be great if you could look at that in FreeMaster and check why it did not run.</P><P></P><P>The motor may not rotate due to DC bus current limit. The maximum current could be modified by DC_BUS_CURRENT_LIMIT and ALIGN_CURRENT_SCALED parameters (both should contain the same value).</P><P>You may also try modifying ADVANCE_ANGLE parameter for tuning Back-EMF detection.</P><P></P><P><BR />I hope it helps you.</P><P></P><P>Have a great day,<BR />RadekS</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
