Question

IHM08M1 with NUCLEO-H743ZI2 board in FOC mode.

Hi! 

I need to control a BLDC motor in FOC mode. I have a NUCLEO-H743ZI and IHM08M1, I know that they are not compatible with the ST morpho connector. But I decided to connect them manually with wires.

On IHM08M1 board I removed capacitors C3, C5, C7, closed jumpers JP1&JP2, and soldered JP5&JP6 to 3Sh.

On Nucleo board I configured advanced TIM1 with 3 Channels: 

TIM_CH1, TIM_CH1N, 

TIM_CH2 TIM_CH2N,

TIM_CH3, TIM_CH3N

And wired them to the power board.

When I trying to generate PWM signal, there are any outgoing signal on any of 3 Phases.

Do I miss something?

Thank you!

Dear @VKost.2​ 

Sorry for the late answer.

As I understand it is important to configure dead time and channel polarities for this power board. I took TIM1 configuration from ST Workbench generated project and it worked nice.
