TMS320F28027: Limited explanation about below FAST estimator parameter

Part Number: TMS320F28027

Hi

Could you give more explanation for below FAST estimator parameter?

We are working at 9000RPM (7 antipode), 10Hz, maximum phase current is 70A. Should we fine tune below parameter? How to adjust? Thanks a lot.

    You don't need to change these parameters as the parameter comments first, for high-speed motors, you can try increase the USER_SPEED_POLE_rps value up to 500.0. Please let's know if you meet any question when motor run to high speed. What's the maximum electric frequency and rated frequency for your motor?
