Status messages of active power limitation
Name Display 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.
Errors and warnings relating to the reactive power setpoint
Name Display Description
Q-VArModFailStt Off No mode for specifying the reactive power setpoint has been se-
lected.
Ok A mode for specifying the reactive power setpoint has been selected
and no error is present.
ComFail
The mode VArCtlCom or PFCtlCom has been selected and the ex-
pected signal with a valid reactive power setpoint has been absent
for at least fiveminutes.
AnInFail
The mode VArCnstNomAnIn or PFCnstAnIn has been selected
and the value measured at the analog input is less than 2mA.
ComInvalid
The mode VArCtlCom or PFCtlCom has been selected and there is
invalid content in the power setpoint information.
