if 100% of Base Current Reference is given, the drive will feed 100% power to the grid.
The situation is the same with the frequency reference set to 52 Hz and with 2.000 Hz
drooping.
Base current reference can be used together with selection
3
of P2.11.5
StartPowerMode: Isochron.Gen. This selection will keep the drive frequency reference
same as the grid frequency, and the power that is fed or taken from the drive is solely
defined by the Base Current Reference parameter.
