: Deactivates dynamic grid support using dynamic reactive current.
Dynamic grid support remains active on account of immunity to inter-
ference.
Reference power
Instantaneous

power
Specifies the power reference for the characteristic curve. 100 % here
corresponds to the nominal power or the actual power at the time the
function was activated, the time when the voltage passes the con-
figured node.

Specifies which voltage is evaluated in a three-phase system.
Hysteresis mode
Off | On
Off:
In non-hysteresis mode, the active power is increased immediately
with dropping voltage.
On:
In hysteresis mode, the power is not increased with dropping
voltage. .
Deactivation gradient
1 - 65,534 [% / min]
If the available power is above the actual output at the time of deactiva-
tion, the power increase back to the maximum power is limited. The
limitation is implemented by an absolute power limitation that in-
creases with a continuous gradient up to the maximum power. The ac-
tual power of the inverter may vary freely below this limit due to a pos-
sible fluctuation in the available power or the target value, but at no
time increases above the absolute power limit.
Deactivation time
0 – 60000000 [ms]
Only evaluated with activated hysteresis mode: Monitoring time during
which the voltage must remain below the lowest configured node be-
fore the function is deactivated.
Settling time
100 – 1,200,000 [ms]
Determines the dynamic behaviour in the event of a change in the act-
ive power set value. With a voltage change, the active power is changed
according to a PT-1 characteristic curve with a settling time of 5 Tau.
Note: The settling time is overlaid with the increasing and decreasing
gradient.
