TMS320F28027F: DRV8305

Part Number: TMS320F28027F
Other Parts Discussed in Thread: DRV8305,

Hi,

I am using TMS320F28027F and DRV8305 for development of sensorless BLDC Controller. My application requires motor to run in clockwise / counter-clockwise direction with max RPM 150000. I have checked  BLDC motor specifications and it is capable to run upto 150000.

In USER.H for user IQ FULL SCALE FREQ I have entered value 1300 so motor can rotate upto 78000.  

#define USER_IQ_FULL_SCALE_FREQ_Hz        (1300.0) 

But to run at 150000 I need to increase that value. What is the maximum value that can be written for USER_IQ_FULL_SCALE_FREQ_Hz .

After increasing user full scale frequency value will motor run at 150000 rpm?

Thank you
