Good morning everybody,

   

Is there any technique which can emulate the slow-start procedure in the electric motor field?

   

I would like to supply my proc 4 board with Zn-air coin cell batteries, but the inrush current is too big to be supplied by the batteries.

   

I'm also implementing all the power modes, but it obviously starts in active mode.

   

Do you think that starting from a low oscillator speed and then arrive to a full-frequency speed should be a good programming strategy?

   

Any hint is highly appreciated.

   

Thank you in advice!

   

Cheers,

   

Andrea
