TMS320F28027F: Tms320f28027f

Part Number: TMS320F28027F
Other Parts Discussed in Thread: DRV8301

Dear sir/Madam,

I have some problems with the motor control. every time I run the motor identification the motor runs good restarting the system also goes well. but If I run it the next day or the system stays off for a while and than starting it again, than the motor hicks up at start rotation, like it is getting overshoot values. so I am looking for possible weird values in our system. I suspect that the some offset re calibration is going wrong, but I don't know. the weird values that I see are the gAdcData; there are some values that goes to - value, see the I values in the screenshot below. I have to mention that the system is used for e-bikes, FOC lab4 torque control.

any support or suggestion is appreciate it.

Kamal

    Are you using a TI hardware kit or custom hardware? Also, you found the system to hiccup when starting fresh using your project based on lab04 with the user.h parameters populated with the values from lab02b/c?

    Hello,

    It is a custom controller. the parameters in the user.h are obtained following the user guide, also used lab02b/c webapp, the evaluation kit DRV8301 and finally troubleshooting following the user guide.

    to be clear the motor runs good once I do fresh troubleshooting, it works bad (hiccups). when I shut down the system for a while and start it again.

    regards,

    Kamal
