Hi,

Maybe you want to check this ongoing discussion:

> \### if phase resistance and phase inductance are known:
> Will initialize Kp and Ki for q and d current PI controllers automatically based on phase resistance, phase inductance and current bandwidth (default 300).
> Needs to be adapted if Ld and Lq are available in the future.
> ⚠️ What if users have set phase resistance and phase inductance but were using default PI parameters ? Is there an impact ?
> 
> \### if phase resistance and phase inductance are not known:
> Same SimpleFOC default values as before are used.
> \### Users that have already tuned their PIs:
> They will overwrite Kp and Ki from their code.
