TLE9879QXA40 Electronic Braking

[smidt]

Hi I have a project requiring some form of electronic braking and I am using the TLE9879QXA40 board to power the motor. Is there any way using software or hardware to achieve this.

Hi,

  Here you can follow the "Infineon-TLE987x-Sensorless-Field-Oriented-Control-ApplicationNotes" to control your motor.

Hi Owen, this document does not cover electronic braking. I was wondering if anyone knows how to enable electronic braking using this motor driver.

Hi, @smidt ,

    Here I found a example about electric car parking brake with an Arduino: electric brake ,  so you can use Arduino Uno as your MCUCARD, TLE9879-BLDC-Shield as your inverter card. And this is the library of our  TLE9879 , you can follow the link to build your platform. Hope this can help you.

Hi @smidt,

Please, can I know the hardware platform you are using? Is it TLE9879 EVALKIT, TLE9879 BLDC Shield or the custom board based on the TLE9879?

If you are using TLE9879 EVALKIT or BLDC shield for Sensorless FOC code then you can follow this community thread: TLE9879 static braking BLDC Motor.

And implement following suggestion.

In the emo_RAM.c file, you can make the following changes to the code and you should get the desired results:

if you need a lower duty ratio of PWM, you can make necessary changes with the compare values.

Please, let us know if you have further questions.

Thank you
