"Return Gradi-
ent 2 Mode"
Off Deactivates the use of
"Return Gradient 2". Rais-
ing the effective power
from the reduced value to
the device rated output
takes place according to
"Return Gradient 1".
On Activates a different rate
of change at which the in-
verter increases the ef-
fective power from the ori-
ginal value to the device
nominal output. Raising
the effective power from
the original value to the
device rated output takes
place according to "Return
Gradient 2".
"Return Gradi-
ent 2"
0.01 ‑ 100 [%/s
]
Rate of change at which
the inverter increases the
effective power from the
original value to the device
nominal output.

Actual power at the moment the limit
value is exceeded
P
red
Reduced power
(1) "Gradient Overfrequency"
(2) "Deactivation Time"
(3) "Return Gradient 1"
(4) "Return Gradient 2"
(5) "Initial Delay"
At P
red
the grid frequency returns to the per-
missible range. After the end of the waiting
time (2), the power is increased to the initial
value P
m
with "Return Gradient 1". The power
is then increased to the device nominal out-
put P
n
with "Return Gradient 2" (4).
