How to set jumpers of X-NUCLEO-IHM08M1 for FOC control?

[LIUJINGJING]

I want to use Nucleo-G431RB and X-Nucleo-IHM08M1 3Sh to control a outer rotor BLDC with FOC. Now I am confusing how to set jumpers.

In the introduction of Motor Profile:

However, in the Quick Start Guide and User Manual of X-Nucleo-IHM08M1 3Sh ,

the requirements are like this:

On the X-NUCLEO-IHM08M1 expansion board, set jumpers: J9 open,

JP3 closed.

For 6-step control (X-CUBE-SPN8 FW), set jumpers: JP1 and JP2 open, J5&J6

on the 1-Sh side. Keep capacitor C5 mounted; in case of poor motor current

regulation during startup, reduce its value.

For FOC control (STSW-STM32100 FW), set jumpers: JP1 and JP2 closed,

J5&J6 on the 3-Sh side. Remove capacitors C3, C5 and C7.

Which one should I follow?

Thank you very much!

Hello @LIUJINGJING​ and welcome to the ST Community.

The Motor Profiler settings (picture) are used to estimate the electrical and mechanical parameters of the motor in use and they do not depend on the control algorithm.

To drive the motor with FOC and 3 shunt configuration you must follow the Quick Start Guide and User Manual UM1996 settings.

Let me know if these info are useful to you, if yes please "Select as Best" label to close the topic.

I used the FOC & 3 shunt setting in the parameters estimate in Motor Profiler. Will it influence the eastimate results?
