TMS320F280039C: InstaSPIN library config params documentation

You may find the description about some of these parameters in the InstaSPIN-FOC and InstaSPIN-MOTION User's Guide https://www.ti.com/lit/spruhj1.

BTW, these parameters are used in the FAST library internally, you don't need to change these default value for these parameters if you use the InstaSPIN-FOC.

These parameters are just needed to be adjusted for low inductance high current motor, and only USER_M1_EST_FLUX_HF_SF needs to be tuned as shown in the header file. A motor with a lower flux will use a small value for USER_M1_EST_FLUX_HF_SF.

As described in comments in header file, these parameters you mentioned above are used in internal lib, and you don't need to change these parameters. We may remove or hide these parameters in next release, just keep these parameters for further debugging if these parameters  may need to be tuned for some special motors.
