Hello,

I am using TI DSP f28335. Using that i am running a three phase motor. I am utilizing the CCS example code from 

PMSM: FOC Sensorless (Delfino F2833x).

I set the base frequency as 60 Hz and speed reference as 0.5. I am expecting the output of the inverter voltage should be following the speed command and should read 30 hz in the voltage waveform. But i measure the frequency as 15 Hz in the voltage waveform (filtered inverter output). 

Please suggest me if i am expecting wrong thing or if i need to edit the program. Note that, i operating at build level 3.

Would appreciate your quick response.

Thanks

Arafat
