MOTIX™ MCU

Hi:

   I Bought a suit of  TLE9879EVALKIT,and after I finished the wiring job, and switch on DC24V power, down loads the BLDC Demo prog to the MCU, But I found that BLDC motor can't run. I checked every thing ,not found anything wrong, finally I got some info from the web, I adjusted the Power supply voltage to 22.0Vdc,than the BLDC motor can rotate. So  I want to know why the TLE9879EVALKIT can't run over 22V?

HI. everyone

I was in trouble.

When I make a bldc MOTOR, if I use one POWERSUPPLY it works and if I use another POWERSUPPLY it doesn't work.
The POWERSUPPLY that works is 30V, 10A (success) and the other POWERSUPPLY is 30V, 20A (failure). Suspected SLEEPMODE or STOPMODE.
Could you please let me know if there is a problem with the code?
thank you

Everybody is good!

I would like to ask, TLE9842-2QX, the power supply voltage of single chip is 12V, then I set the GPIO port as out-of-PP mode, what is the output voltage V? There is no content about GPIO port voltage control in the manual.

Thanks！

Hi I am working on  bldc motors , and I used the software code exemple in keil library (FOC) to drive the motor in sensorless mode and I want to know   how much ressources it takes to run  this exemple code (RAM, flash memory and CPU)? is it possible to get these informations ? .

thank you .

Best regard.

Hello everyone,

I have spent many hours working on a single BLDCSHIELDTLE9879TOBO1 evaluation board mated to an Arduino Uno R3, trying to run the setParameter() function to change the parameters of the control algorithm within the TLE9879 device.

The TLE9879 device was programmed at the factory, I haven't changed it, and I have no desire to do so....

I tried running the "BLDC Single motor test" example, and then adding "shields->setParameter(FOC_START_ACCEL,1);"  at various points after "shields->setMode(FOC);" is called. I have tried adding "BOARD1" to the setParameter command but this has no affect either..

I get an acknowledgement in the serial data coming back to my PC stating that the parameter has changed, but there is no difference in the way that the evaluation board behaves.

I have tried this approach of changing multiple different parameters, within both the BEMF and FOC modes, but nothing seems to affect the behaviour of the shield...

I hope that someone can help... 😀

Kind regards,

Peter
