System Manual
Value/range Explanation
Off Sets reactive power to 0 kVAr
and displacement power factor
cos φ to 1
VArCtlCom Specifies reactive power via ex-
ternal control unit, such as the
Power Reducer Box
PFCtlCom Specifies the displacement power
factor cos φ and the excitation of
the displacement power factor
via an external control unit such
as the Power Reducer Box
VArCnst Specifies reactive power in kVAr
via the parameter Q-VAr
VArCnstNom Specifies reactive power in % via
the parameter Q-VArNom
VArCnstNomAnIn The reactive power setpoint is im-
ported via an analog input.
PFCnst Manual specification of the dis-
placement power factor cos φ
and excitation of the displace-
ment power factor via the param-
eters PF-PF and PF-PFExt.
PFCnstAnIn Specifies the displacement power
factor cos φ at the analog input
QExlSpnt via control unit
PFCtlW Specifies the displacement power
factor cos φ depending on the
feed-in power
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)
VArCtlVolHysDbA Specifies reactive power as a
function of the grid voltage with
activation power
