Status messages of the reactive power setpoint
Name Display Description
Q-VArModStt Off No mode for specifying the reactive power setpoint has been se-
lected.
VdcMax The reactive power is limited due to DC voltage being too high.
VacLimMax The reactive power is limited due to AC voltage being too high.
VacLimMin The reactive power is limited due to the AC voltage being too low.
SMaxVdcHigh The maximum apparent power value is reduced. If the maximum DC
voltage increases, the reactive power is reduced.
SMax The reactive power is limited by the maximum apparent power.
Tmp The reactive power is limited by temperature derating.
AmpAC The reactive power is limited via an AC current limitation.
P The reactive power is limited due to the priority of the active power
setpoint.
FrtLim The reactive power is limited due to the FRT voltage limit.
