ST Motor Profiler on Custom board based on B-G431B-ESC1

[alessandro239955_stm1]

Hi all,

I am designing a motor controller board based on the B-G431B-ESC1 board.

What are the requirements to be able to use the ST Motor Profiler on my custom board?

Let's make the assumption that I am using the same schematics (same parts as the B-G431B-ESC1 board) but different layout.

Is it sufficient to configure the board using the MotorControl Workbench 5.4.4 in order to be able to use the Motor Profiler?

Best,

Alessandro

Hello Alessandro,

About your first question:

• yes, B-G431B-ESC1 is supported by the Motor Profiler delivered since last MCSDK5.4.4 and yes if your design is fully aligned with our board (pinout) the profiling should work exactly the same way.

About the second one:

• The profiler and MCWorkbench are 2 different tools. So no need to use the MC Workbench for the profiling phase.
• In a second step, when the profiling phase is completed, parameters from the profiler will be used by the MC Workbench to configure your project.

Thanks and best ergards,

Claire

Thank you for your response.

Is it possible to change the shunt resistor value? Assuming that the pinout of my custom board is the same, what happens if I change the shunt resistor? Is it possible to tell the profiler that a different shunt has been used?

Unfortunatly no Alessandro, you cannot change the shunt resistance value.

Then the gain of the power board will be then different than the gain configured inside the firmware, and it will not work anymore.

And there is no way to tell the profiler that the shunt changed.

Best regards,
