Dear all,
My first time here .

I just started a soft starter project and realized a lot of things different from drive.

One question:

How does the jogging mode be realized in Soft starter? Normally they provide jogging speed x%--y%, but where does the speed value come from?

Thanks for your help!

Hello liloyaya

Welcome to the forum.
Some soft starters do provide a crude reduced speed jog by using a simple form of six pulse cyclo converter.
By only switching some SCRs per cycle rather than all of them, they can provide a magnetic vector rotating by limmited degrees each cycle rather than 360 degrees per cycle.

Best regards,
Mark.
