Part Number: TMS320F28069F
Other Parts Discussed in Thread: TMDSHVMTRINSPIN

Hi,

I have a TMDSHVMTRINSPIN, a F28069M control card,and a 311v, 1000W PMSM.

I successfully spun with GUI composer,and I get the parameters of the motor.But when I run the lab02b  step by step according to the guide,he identified motor parameters are far from being correct and the motor doesn't spin.

I don't know what the problem is. Can you help me?

Best regards

Yang

    Please follow the instaSPIN lab guide to identify and run the motor step by step, it seems like you didn't set "gMotorVars.Flag_Run_Identify" to "1" to start the motor.

    I followed the instaSPIN lab guide step by step,I followed the guide and set the  "gMotorVars.Flag_Run_Identify"  option to 1, "gMotorVars.Flag_Run_Identify" is 0 because the identification process has been run(I think)

    1. Change the identification parameters based on the specification of the motor.

    #define USER_MOTOR_RES_EST_CURRENT (1.0) // During Motor ID, maximum current (Amperes, float) used for Rs estimation, 10-20% rated current
    #define USER_MOTOR_IND_EST_CURRENT (-1.0) // During Motor ID, maximum current (negative Amperes, float) used for Ls estimation, use just enough to enable rotation
    #define USER_MOTOR_MAX_CURRENT (3.82) // CRITICAL: Used during ID and run-time, sets a limit on the maximum current command output of the provided Speed PI Controller to the Iq controller
    #define USER_MOTOR_FLUX_EST_FREQ_Hz (20.0) // During Motor ID, maximum commanded speed (Hz, float), ~10% rated

    2. Use lab01b and lab01c to verify if the hardware works well. It seems like the inverter didn't have any voltage output to the motor, please make sure that the correct related lab project is imported for this kit.
