C2000WARE-MOTORCONTROL-SDK: Universal Motor Control Lab motor parameters identification results abnormal.

Part Number: C2000WARE-MOTORCONTROL-SDK

Hi all:

I am testing Lab4 on HV board. My Motor has parameters as: 2.3Ohm phase to phase resistance; 14.5mH phase to phase inductance; Back EMF 28V/krpm;

I found that whether the motorVars_M1.flagEnableOffsetCalc = false or true in sys_main.c will result in different motor identification result.

When true, Rs=0.001, flux=0.49.

When false, Rs=1.8, flux=0.019.

I think neither of the two group of parameters are right.

If I restart the motor right after identification, they both work fine. But if I copy the results to user_mtr1.h and reload the program, only the first group works. The second group will lead to a overcurrent fault. I tried to copy the PI parameters comes after identification and it still fails.

Can you tell me which part is wrong and how to fix this?
