QoDQ-
VArMod** Reactive power setpoint
in the operating mode
"Q at Night" Off Sets reactive power to 0 kVAr
and displacement power factor
cos φ to 1 Off
VArCtlCom Specifies reactive power via ex-
ternal control unit, such as the
Power Reducer Box
VArCnst Specifies reactive power in kVAr
via the parameter QoDQ-VAr
VArCnstNom Specifies reactive power in % via
the parameter QoDQ-VArNom
VArCnstNomAnIn The reactive power setpoint is im-
ported via an analog input.
VArCtlVol Specifies reactive power as a
function of the grid voltage
VArCtlVolHystDb Specifies reactive power as a
function of the grid voltage (Q =
f(V) characteristic curve)
