DRV8329AEVM: Position control using LaunchXL F2800137

Part Number: DRV8329AEVM
Other Parts Discussed in Thread: LAUNCHXL-F2800137, , TMDXIDDK379D, C2000WARE

Greeting,

We are developing a bldc controller using DRV8329AEVM + LaunchXL-F2800137.

How can we develop a position control using the same.?

Regards
Amal

  • Hi Amal,

    We don't have any position control software solution for the low-cost F280013x device. Our TMDXIDDK379D has some software solutions that include position loop, this is for higher performance C2000 devices however.

    Are you planning to use a position sensor / encoder device?

    Best,

  • Hi Kevin,

    Thanks for replying.

    We are using encoder(400cpr) and our motor runs at 4000 rpm max.
    We are developing a low cost position controller for agro-machinery automation which may not require ultra high resolution as normal position controllers.
    Does universal motors control lab has any libraries regarding the same?

  • Hi Amal,

    OK understand your goal.

    Does universal motors control lab has any libraries regarding the same?

    Sorry, but it does not have any position loop / controller implemented in the software projects. The Universal Lab focuses on lower performance current / torque and speed control applications. The best suggestion I have is to refer to our other solutions that do implement position control and try to pull the SW / logic into the Universal Lab.

    I can suggest the FCL project below as well, Build Level 5. There is a project for F28004x and F28002x which are more similar devices to F280013x.
