Name Description
PF-PFStop** Displacement power fac-
tor cos φ at characteristic
curve point 2
The lower limit is defined
by the parameter PFAb-
sMin.
PF-PFExtStop** Excitation of the dis-
placement power factor
cos φ at characteristic
curve point 2
PF-WStr** Feed-in power in % at
characteristic curve
point 1
PF-WStop** Feed-in power in % at
characteristic curve
point 2
PF-WLockIn- Activation voltage of the
Vtg** cos φ(P) characteristic
curve, in %, relative to
the nominal voltage
PF-WLock- Deactivation voltage of
OutVtg** the cos φ(P) characteris-
tic curve, in %, relative to
the nominal voltage
PF-WLockTm Waiting time for activa-
tion or deactivation of
the cos φ(P) characteris-
tic curve
Q-VDif** Definition of voltage vari-
ation leading to a
change in reactive
power
Q-VArGra** Definition of the reactive
power setpoint change in
one voltage step
Q-VDifTm** Time period for which a
voltage change must be
present before the reac-
tive power setpoint Q-
VArGra changes.
