Action in this menu/meaning
If one or more phase/phase or phase/neutral conductor voltages move
above the configured threshold, the inverter changes to zero current
mode. The total current is regulated to virtually zero.

Nominal value of the phase/neutral conductor voltage used as a refer-
ence voltage for formula (1) and (3). Adjustable in the range from level 1
undervoltage protection to level 1 overvoltage protection.
Amplification factor for the negative sequence used in the calculation of
the reactive current using formulae (2) and (4) Can be configured inde-
pendently for drops and spikes.

Dynamic grid support through fast feeding of residual current activated
in the case of voltage events with a voltage change greater than the
dead band.

Standard: The reactive current according to the formulae (2) and (4) is
fed as additional reactive current. The means that sum of the pre-fault
and additional reactive current is fed in.
Only dynamic: The reactive current according to the formulae (2) and
(4) is fed in as absolute reactive current. This means that regardless of
the reactive current before the voltage event, only the reactive current
is fed in according to the formulae (2) and (4) is fed in during the voltage
event.
Mode 1: When calculating the reactive current, the value of the dead
band is not subtracted from the amount of voltage change.
For overvoltage and undervoltage events, formula (2) therefore applies.
Mode 2: When calculating the reactive current, the value of the dead
band is subtracted from the amount of voltage change. For overvoltage
and undervoltage events, formula (4) therefore applies:
