Run jiggle and nosie on TMDSHVMTRPFCKIT and F28035 with servo motor

 Hi  

   I used TMDSHVMTRPFCKIT and F28035 with self servo motor.

    It didn't run smooth on HVPM_Sensorless  level 2 and level 3 build that run jiggle and nosie.

    I didn't clear The servo motor parameters. 

    But It can run fine with Demo code that flash at F28035(control card ) and HVMTRPFCKIT-GUIv1.

    Could you give me The parameters on Demo code ???

    How can I make it run smooth ???

    How can I make it synchro ???

    Regards,

    Jimmy

    Jimmy,

     

      Level 2 and level 3 builds still perform a forced D-axis angle.  The sensorless observer is not being used to find the D-axis angle yet.  Once you get to build level 5, the motor should run smoothly.

     Hi Erc,

         I was still jiggle on level5.

        Maybe , I didn't tune fine PID on current loop.

       Did I tune PID on lsw=1???

       How can I tune it ???

       Check pid1_id.Fdb in the watch windows with continuous refresh feature whether or not it should be keeping track pid1_id.Ref for PID_REG3 module. If not, adjust its PID gains properly.

    Check pid1_iq.Fdb in the watch windows with continuous refresh feature whether or not it should be keeping track pid1_iq.Ref for PID_REG3 module. If not, adjust its PID gains properly.

    Did you update the settings for your motor in HVPM_Sensorless-Settings.h?

    Are you following the user guide on how to tune the Id, Iq, and Speed PI controllers?

     Hi ,

          I have tune Id and Iq .

         But, when I run on level5 , It auto run revers. You see that the smo1.Theta revers with rg1.Out . 

        This servo motor can run very well on HVMTRPFCKIT-GUI-FlashImagev1.out .

    Hi  ,

       I look for DMClib Configuration.

       On System Parameters & Requirements  (i.e. User inputs) field,  I don't known which parameter match with Designed voltage gain constant in switching function , Cut-off frequency of low-pass filter and Deadband requirement for Inverter ???

      Does the DMClib Configuration be used on HVMTRPFCKIT-GUI-FlashImagev1.out??? 

    Regards,

    Hi Chris ,

         I review my servo motor then tune I loop Ok.

        I have a phenomenon. when I enable Realtime Options (Halt the target before any debugger access) on Code Composer Studio , The F28035 responded to Motor  control too late .

       How can I read data on realtime and DCU work fine ???

    Regards,
