Frequency of the max-
imum deactivation
threshold
45 - 50.2 (Hz)
Frequency of the min-
imum deactivation
threshold
45 – 50,2 (Hz)
Deactivation range lower limit:
Only evaluated in mode 1.
The function is deactivated if the frequency returns to the deactivation
range and remains in this range for the duration of the deactivation
time.
Deactivation range upper limit:
Only evaluated in mode 1.
The function is deactivated if the frequency returns to the deactivation
range and remains in this range for the duration of the deactivation
time.
P(f) deactivation time
0 – 3600 [s]
Only evaluated in mode 1.
The function is deactivated if the frequency returns to the range
between the minimum and maximum deactivation threshold and re-
mains in this range for the duration of the deactivation time.
P(f) deactivation gradi-
ent
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.
Maximum dynamic
gradient frequency
50.22 – 70.5 [Hz]
Minimum dynamic
gradient frequency
45 – 50 [Hz]
Dynamic gradient maximum frequency:
If dynamic gradient mode is activated, the gradient is calculated in order
to guarantee a linear power adjustment and reach the maximum char-
ging power if the frequency rises to the maximum configured frequency.
Dynamic gradient minimum frequency:
If dynamic gradient mode is activated, the gradient is calculated in order
to guarantee a linear power adjustment and reach the maximum feed-in
power if the frequency drops to the minimum configured frequency.
P(f) settling time
200 – 2,000 [ms]
Determines the dynamic behaviour in the event of a change in the act-
ive power limit. In the event of a change in frequency, the active power
is altered subject to a PT-1 characteristic curve using a settling time of 5
Tau.
The settling time is overlaid with the increasing and decreasing gradient.

1 – 65534 [% / min]
Specifies the dynamic response on changing the active power for power
increase and decrease. With a voltage change, the active power is
changed with the specified gradient.
Note: The gradient is overlaid with the settling time.

FRT
Dynamic grid support (Fault Ride Through)
A generation plant’s ability to remain immune to voltage drops and voltage spikes in the supply system is a key
element in establishing a reliable energy supply. Immunity to interference ensures that brief disruptions do not
result in a loss of generation capacity in a larger range of an interconnected grid. Grid support by a fast feeding
of residual current also limits the spatial extent of the incident.
With its dynamic grid support by way of immunity, the device has this characteristic. The ability to remain on
the grid is particularly relevant. The protective settings also determine the device’s ability to remain on the grid
or not. Protective settings take the upper hand over the capacity of immunity to interference.
