BOOSTXL-DRV8323RS: Motor not work in InstaSPIN Projects

Hello,

InstaSPIN-FOC is a sensorless control scheme, and so it should not interface with Hall sensors on the motor.

Does the motor try to spin but shut down? Or does it not spin at all?

Thanks,

Matt

Hello,

Are you using MOTORWARE? 
Which lab are you trying to run?

THanks,
Aaron

Hi,

I am using MOTORWARE.
I try boostxldrv8323_revA example(1b,1c,2c,5a).
I follow the PDF (InstaSPIN Quick Start Guide) build lab and try use guicomposer to control my motor.
But my motor does not work.

The motor is not broken. I have used the another driver-board to control my motor, and it worked successfully.

Thanks,
Jerry

Hi Jerry,

Did lab 2c identify and/or spin the motor at all after hitting "Enable System", calculating the offsets of the board, and then running the motor?

Lab 1 should ensure that the H/W connects and blinks an LED, and then lab 2 should identify the motors correctly. Do these values get updated in the GUI?

Have you tried running the projects in CCS?

Have you validated the PWMs are working for the motor and the ADCs are set up correctly for phase voltages and currents?

If the motor does not spin sensorlessly, then the firmware may not be set up correctly for the BOOSTXL-DRV8323RS. 

Thanks,
Aaron

Hi,Aaron

I check Lab1 the H/W connects and blinks an LED, and then update motor parameters.

But in Lab2, after I press "Enable System", the button will be cancelled after a while. Why is this? Is it because the parameter setting does not meet the regulations?

Thanks,
Jerry

Hi Jerry,

This could be due to a variety of factors, such as the motor current maxing out due to incorrectly identified Rs and Ls parameters, or a fault generated from the DRV device. Unfortunately, I do not have much experience with MotorWARE rather I have more experience with MotorControl SDK (newer version of MotorWARE). I know MotorWARE is not supported anymore since transition to MotorControl SDK. 

Would you be willing to evaluate the LAUNCHXL-F280049C + BOOSTXL-DRV8320RS solution using MotorControl SDK? 

I can forward this thread to the C2000 team for advice or references with debugging MotorWARE, but I'm not sure if people still currently support it. 

Thanks,
Aaron

Hi Aaron,

I want to try to use MotorControl SDK to control BLDC motor.
I hope you can tell me how to port LAUNCHXL-F280049C + BOOSTXL-DRV8320RS to MotorControl SDK.

Btw, does MotorControl SDK provide a method to read RPM using a quadrature encoder?
My motor HALL sensor is broken, but there is a quadrature encoder that can detect the speed.

My main purpose is to control the motor speed and use the encoder to detect the position. I have tested other drives using FOC to control, but the RPM accuracy is ±6, so I want to ask what RPM accuracy the SDK can detec

Thanks,
Jerry

Hi Yanming ,

I am try motorcontrol SDK example.

Ask a question about the connector, because the  BOOSTXL-DRV8323RS is used, I refer to the reason why the PDF(BOOSTXL-DRV8323Rx EVM User’s Guide & BOOSTXL-DRV8320RS EVM User’s Guide) contact pins do not completely correspond, because it is the Launchxl-F28069M, do I need to use the plug-in pins for connection?

Thanks,
Jerry

Sorry, this is my first time to use TI product, so I have some doubts about the pin setting.

I read this document.

Launchxl-F28069M and Launchxl-F280049C (J4,J2) are similar, but why J4-12/GPIO23 (launchxl-f280049c) connect to J4-19/GPIO57 (launchxl-f280049c)? 

InstaSPIN Quick Start Guide
Launchxl-F28069M and BoostXL-DRV8323RS Connection don't break some connections.
Are these pins originally connected like this or are they corresponding to the board?
So change these pins connected that I can use Launchxl-F280049C +  BoostXL-DRV8323RS, I don't have to change the settings of the program so that the board can be controlled.

Can MotorControl SDK support Launchxl-F28069M, I only have this board.
If it can't support, maybe I should be use MOTORWARE or buy a Launchxl-F280049C to control.
I mistakenly thought you were talking about Launchxl-F28069M.

Thanks recovery, but back to the question at the beginning.

I have download and bulid the project, but my motor can't run in the InstaSPIN_UNIVERSAL GUI.

I check Lab1 the H/W connects and blinks an LED, and then update motor parameters.
But in Lab2, after I press "Enable System", the button will be cancelled after a while. Why is this? Is it because the parameter setting does not meet the regulations?

 Aaron say motor current maxing out due to incorrectly identified Rs and Ls parameters, so how can I do? Should I don't setting any motor parameters for all lab project or some setting I forget?

I will buy Launchxl-F280049C and try  MotorControl SDK next week, but I also want to know how to edit the lab to control my motor in MotorWare.

You might run the related labs with CCS directly. The InstaSPIN_UNIVERSAL GUI can't support this kit.

 Please follow the lab guide in the folder below and use the examples download from the link mentioned above.
