openinverter forum

Hi, new here so please go easy.

We've just purchased some SDU's and open inverter boards, seems simple enough but we decided to use this in an old T2 so we need to limit the power.

Looking at the parameters, i'm not 100% where to start but asking chat GPT to change parameters it gives me something like this which i doubt is ok to use straight away but wondered if any one could help guide me in the correct direction of where to begin or if someone has already done something like this link me to the forum post as i found nothing in search

boost (dig): Reduce from 2200.00 to around 1000.00 or lower.

fweak (Hz): Reduce from 220.00 to 150.00 or lower.

fconst (Hz): Reduce from 800.00 to 600.00 Hz.

udcnom (V): Reduce from 360.00 V to around 300.00 V.

fslipmin (Hz): Reduce from 2.00 to 1.00 Hz.

fslipmax (Hz): Reduce from 6.00 to 4.00 Hz.

fmax (Hz): Reduce from 600.00 to 400.00 Hz.

Thanks you, Jamie

Oh god, what a load of rubbish

I'd start by dropping fslipmax to 2 or 1.5 Hz and fslipmin to 1.5 Hz as well. Should already get you the reduction.

Thank you, we will try this first - Is there any info you can link me to which will give me some more information on this or be able to calculate it? All good doing it / copying and pasting but would like to learn more about it for my own future reference

Maybe this helps
