LAUNCHXL-F28027F: Motor Identification Problem -FETLA_OC

Part Number: LAUNCHXL-F28027F
Other Parts Discussed in Thread: DRV8301, BOOSTXL-DRV8301

Hi TI community,

I have been undertaking a project where I am required to control the speed of a custom-made rotary pump (3 phase BLDC) using a LAUNCHXL-F28027F & BOOSTXL-DRV8301. I have tried to complete Lab02b & Lab02c (GUI) but I am getting the following fault and I cannot enable the system to begin the identification sequence. I have taken a look at the DRV8301 data sheet; however, I am still unsure what exactly is causing this issue and i do not want to disable the OC protection. Could someone please help me find a solution to my problem?

Best Regards,

Riley

Motor Details: Max: 5000rpm, 1 A, 15V.

  • 1. I guess you changed the setting of DRV8301, it seems the OC_ADJ_SET is too small to cause the overcurrent fault. You may increase the OC_ADJ_SET based on your h/w board and motor.
    2. You might set the right USER_MOTOR_RES_EST_CURRENT, USER_MOTOR_IND_EST_CURRENT, USER_MOTOR_MAX_CURRENT and USER_MOTOR_FLUX_EST_FREQ_Hz based on the motor specification. The USER_MOTOR_FLUX_EST_FREQ_Hz in user.h may be too small for identification.
