Description
P-WModStt
Off
No mode for active power limitation has been selected.
WMax
Active power is limited by specification of an upper limit. This limit is
based on
Pmax
.
Hz
Active power is limited by a frequency increase.
Tmp
Active power is limited by temperature derating.
AmpPv
Active power is limited via a PV current limitation.
AmpAC
Active power is limited via an AC current limitation.
SMax
The active power is limited by the maximum apparent power.
Q-VAr
The active power is limited due to the priority of the reactive power
setpoint.
QEnsure
The active power is limited due to the intermediate storage of reac-
tive power.
P-Vtg
The active power is limited due to the characteristic curve P(V).
VdcMax
The active power is increased via the setpoint due to the DC voltage
being too high.
AmpPvOptiprot
For the order option "Optiprotect", the active power is limited due to
switch currents being too high.
