STEVAL-IPM10B Evaluation Board Purpose of "PWM_Vref" Pin

[Hasan06]

Hello again, dear STMicroelectronics team,

While reviewing the schematic sheets of the STEVAL-IPM10B Evaluation Board, I came across a connector pin labeled 'PWM_Vref' (highlighted with a green circle in the image below). However, I couldn't find this pin mentioned in any of the other schematic sheets.

I would like to ask: What is the purpose or function of this pin?

Thank you in advance for your support.
Best regards,

This is a remnant from the time when the 34-pin motor control connector was defined. At that time, this signal was used for special daughter boards. So you can safely ignore the signal.

Does it answer your question?

Regards
