In the documentation for the STEVAL-CTM009V1 demo board there is a table where the minimum DC bus voltage is listed as 36V, is this really the minimum voltage for the power stage? Why can I not run this board using a motor supply (DC Bus) of 12V ?

I don't need the motor control board, I have my own, I just need the power stage and the capacitor board.

I', not a big expert of this board but I think it is possible to use it with a DC bus voltage of 12V.

Let's try. Maybe is just a documentation error.

Hello Sjenn,

I have to pilot a 12V motor with this board but I'm not sure if it's possible with this board,

Did you succeed to pilot it with 12V?

Thanks in advance,

Hi NBOUM.1

In the end we found a different solution so we never tested the board at 12V - sorry! However in my opinion - FWIW - it will work.

I will see if we can get the board up and runnign and test it at 12v.
