Description
No mode for active power limitation has been selected.
Active power is limited by specification of an upper limit. This limit is
based on Pmax.
Active power is limited by a frequency increase.
Active power is limited by temperature derating.
Active power is limited via a PV current limitation.
Active power is limited via an AC current limitation.
The active power is limited by the maximum apparent power.
The active power is limited due to the priority of the reactive power
setpoint.
The active power is limited due to the intermediate storage of reac-
tive power.
The active power is limited due to the characteristic curve P(V).
The active power is increased via the setpoint due to the DC voltage
being too high.
For the order option "Optiprotect", the active power is limited due to
switch currents being too high.
Description
No mode for specifying the reactive power setpoint has been se-
lected.
A mode for specifying the reactive power setpoint has been selected
and no error is present.
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 five minutes.
The mode VArCnstNomAnIn or PFCnstAnIn has been selected
and the value measured at the analog input is less than 2 mA.
The mode VArCtlCom or PFCtlCom has been selected and there is
invalid content in the power setpoint information.
