: Deactivates dynamic grid support using dynamic reactive current.
Dynamic grid support remains active on account of immunity to inter-
ference.
Reference power
Instantaneous
power | Nominal
power
Specifies the power reference for the characteristic. 100 % to be the
nominal power or the actual power at the instant of activation of the
function, the instant when the voltage passes the configured node.

F
Select the voltage to be rated.
Defines which voltage in a three-phase system is to be evaluated.
Hysteresis mode
Off | On
Off:
In Non-Hysteresis mode, the active power is increase immediately
in cases of falling voltage.
On:
In Hysteresis mode the power is not increased in case of falling volt-
age. .
Deactivation gradient
0 - 65534 [% / min]
If available power is above actual power at the instant of deactivation,
the power increase back to maximum power is restricted. The restric-
tion is implemented by an absolute power limit that is increasing with a
continuous gradient up to maximum power. The actual power of the in-
verter may vary freely below this limit based on possible fluctuation of
the available power or set point, but will never increase above the abso-
lute power limit.
Deactivation time
0 – 60000000 [ms]
Only evaluated in Hysteresis mode On: Observation time for voltage to
remain below lowest configured node before function is deactivated.
Increasing output gra-
dient & Decreasing
output gradient
1 - 65534 [% / min]
Specifies the dynamic behaviour at change of active power change for
power increase. On a voltage change, the active power is changed with
the specified gradient.
The gradient is superimposed with the settling time.
Specifies the dynamic behaviour at change of active power change for
power decrease. On a voltage change, the active power is changed with
the specified gradient.
The gradient is superimposed with the settling time.
Settling time
100 – 1200000 [ms]
Specifies the dynamic behaviour at change of active power set point. On
a voltage change, the active power is changed according a PT-1 charac-
teristic with a settling time equal to 5 Tau.
Note: The settling time is superimposed with the increase and decrease
gradient.
Number of nodes

Power
0.0 -100.0 [%]
Voltage
0.0 -126.0 [%]
Up to 5 nodes configurable for voltage [V] and power [% Pref]. The
power-value of the first and the last value pair is also used as maximum,
minimum respectively active power value which is valid beyond the lim-
its of the characteristic.
