CCS/DRV8301-69M-KIT: Problem with InstaSPIN-MOTION GUI

Part Number: DRV8301-69M-KIT

Tool/software: Code Composer Studio

      Hi.Recently, I bought a DRV8301-69M-KIT + LVSERVOMTR,the motor in LVSERVOMTR is teknic_2310P. When I used InstaSPIN-MOTION GUI in software of MOTORKITSCNCD69MISO(motorkitscncd69miso_v104), I had some problems to control the motor. I firstly test "Motor Identification", it was ok and the motor rotated smoothly. But when i test function "Estimate System Inertia" ,the motor rotated chaotically. Even I passed "Estimate System Inertia" , the next evaluation "Tune the SpinTAC Speed Controller" was also abnormal. In this step, the motor was uncontrollable and  shock severely. I am sure the wire connection is ok, because when I use InstaSPIN UNIVERSAL GUI, the example projects (labs) worked well. I think, maybe the firmware of "appProgram.out" in motorkitscncd69miso_v104 is broken. Where can I get a right "appProgram.out" for testing the complete functions of InstaSPIN-MOTION GUI ? Thanks a lot!

    Hi,

    Most of the TI engineers who respond on this forum are based in Houston.  Many have been affected by the recent hurricane & floods.  This happened last week.

    As a result, please excuse our delays in response.  We should start catching up on responding over the coming week.


    Thank you,

    This GUI is only used for general demonstration. You can use the MotorWare based projects with careful consideration paid to setting up hardware and software scaling for proper motor ID and best performance. The instaSPIN lab guide has the detail description on how to setup and run different labs, you can use lab02b to identify motor parameters and use lab05c to identify the motor inertia in CCS, and then use other lab project to run the motor.

    You can download the GUI software and re-install it if you want to run the motor with GUI again, the appProgram.out will be programmed into controller gain when you run the GUI in \guicomposer\webapps\InstaSPIN_MOTION_F2806xM.

    Thank you for your reply. Yes, I want to use InstaSPIN MOTION for general demonstration.Because I want to evaluate all functions in a single GUI conveniently. I have tried re-install the  InstaSPIN MOTION GUI, whatever from the U disk with the development kit or from the network link you provided. Sine the seperate labs in motorware worked well, maybe there is some problem with appProgram.out in motorkitscncd69miso_v104.

    Refer to the "Quick Start Guide of GUI", you have to run motor parameters identification and inertia identification once first, and then run other SpinTac functions.
    You can download GUI software to extract, and the copy the "InstaSPIN_MOTION_F2806xM" to "\ti\guicomposer\webapps\", the software and app*.out should work well.

    Sorry, I have run motor parameters identification and inertia identification as the "Quick Start Guide of GUI" says, indeed. In motor parameters identification, it looked normal (the motor ran smooth) and passed. But in step of inertia identification, there were problems, the motor could not run and only shaked. And, I have re-install GUI from www.ti.com/.../motorkitscncd69miso, but it failed all the same !

    I am having the same problem here running with instaspin motion GUI, motor can be identified and running smoothly, inertia can be estimated but motor will jerk. Afterthat motor cannot be controlled properly in tuning window and always trigger fault error (red LED on). The motor tends to move intermitently while i set the target speed to zero rpm. May I know have you solved it? Can you please share with me your solution? Thank you.
