TMS320F280049C: The built-in TRAJ in the FAST estimator

Part Number: TMS320F280049C

Hi,

The forum post at TMS320F280049C: MotorID - C2000 microcontrollers forum - C2000™︎ microcontrollers - TI E2E support forums  mentions that “This Traj is just for identification to control the Id current.” However, I noticed that lab05 also uses the built-in Traj for speed control after motor identification. Based on my testing, the built-in Traj appears fully capable of performing the functions of an independent Traj, and I successfully ported it to lab07. So what is the exact reason for using an independent Traj? Or am I missing something?

Thank you!
