HSO Requirement for P-NUCLEO-IHM03 kit

[Zek_De]

Hi everyone,
I am trying to activate HSO option for sensorless control which as much as I know this feature is to start motor without moving, but I cant activate HSO option with these option in attached.

I cant find the problem. Thanks in advance.

Hello Zek_De,

Unfortunately, the P-NUCLEO-IHM03 kit is not compatible with the HSO option that requires phase voltage sensing.
You will need to use dedicated hardware boards: STEVAL-LVLP01 and B-G473-ZEST1S-B, which are supported in X-CUBE-MCSDK-6.
Please also refer to the HSO startup guide located in Documentation/HSO_Startup_Guide.pdf.

Best regards,

Fouad

according to workbench also I can use these, right?
EVALSTDRIVE101
NUCLEO-IHM09M2
B-G473E-ZEST1S
Because I can select these 3 in workbench application.

Hello @Zek_De

As previously mentioned, if your goal is to generate a sensorless project with HSO enabled, we kindly recommend selecting the following:

Power board: STEVAL-LVLP01
Control board: B-G473E-ZEST1S

Best regards,
Fouad
