TMS320F28062F: MotorID fail when testing ACIM

Part Number: TMS320F28062F
Other Parts Discussed in Thread: MOTORWARE

Hi Champs,
My customer is using F28062F and Instaspin for air compressor drives. The motor type is ACIM, and motorware's version is v17. They found motorID would be fail after locking the motor. You can find the phase current as follows during Ls identification, after that the state machine would be turned to error. 
Would you kindly help to suggest how to modify the user.h to identify the motor successfully? They have tried to change the USER_MOTOR_FLUX_EST_FREQ_Hz and USER_MOTOR_RES_EST_CURRENT.
And also they wanted to know do we have plan to develop ACIM motorID without locking the rotor?
Thanks.
 
BR,
Young

    Need to set below parameters properly also in user.h based on motor.
    #define USER_IDRATED_DELTA // 0.00001~0.0001
    #define USER_MOTOR_RATED_FLUX // calculated a initial value used 0.8165*220.0/50.0
    #define USER_MOTOR_IND_EST_CURRENT // negative 10%~20% of rated current of motor

    No solution in short time, but had a plan to develop it in future.
