TMS320F28069M: Motor running problem based on lab11e

Part Number: TMS320F28069M

Dear team:

A customer of mine has abnormalities in the motor when running lab11e. The motor can run normally when it is rotating, but it cannot be switched to reverse. Moreover, when the motor is reversing or at low speed, it will get stuck and vibrate. The following are the motor parameters (data from lab03a):

//! \brief USER MOTOR & ID SETTINGS
#define MY_MOTOR 113
//#define USER_MOTOR HighCurrent_LowInductance
#define USER_MOTOR MY_MOTOR
#elif (USER_MOTOR == MY_MOTOR)
#define USER_MOTOR_TYPE MOTOR_Type_Pm
#define USER_MOTOR_NUM_POLE_PAIRS (2)
#define USER_MOTOR_Rr (NULL)
#define USER_MOTOR_Rs (0.878300548)
#define USER_MOTOR_Ls_d (0.00130555173)
#define USER_MOTOR_Ls_q (0.00130555173)
#define USER_MOTOR_RATED_FLUX (0.0330096558)
#define USER_MOTOR_MAGNETIZING_CURRENT (NULL)
#define USER_MOTOR_RES_EST_CURRENT (1.0)
#define USER_MOTOR_IND_EST_CURRENT (-1.0)
#define USER_MOTOR_MAX_CURRENT (3.0)
#define USER_MOTOR_FLUX_EST_FREQ_Hz (20.0)
// this section defined in user_j1.h or user_j5.h

Is this related to the settings of “offsets”?

Best Regards
