Q_of_P
P: Active power (independent values) from -100% to 100% of nomi-
nal power
-
Q: Reactive power (dependent values) from -100% to 100% of nomi-
nal power

5.3.3
Q(S) - Reactive Power as a Function of Apparent Power
See above, Section "Maximum apparent power" (only available if control mode 3 has been selected in the parameter
ModeSelect
).
5.3.4
Q(ext) - Reactive Power as a Function of an External Setpoint
See above, Section "Maximum reactive power" (only available if control mode 5 has been selected in the parameter
ModeSelect
).
5.3.5
PF(P) - Power Factor as a Function of Active Power
This control mode uses the nominal active power to generate a reference value for the power factor (PF) so that the
grid voltage can be controlled at the point of common coupling. The control mode contains two additional parameters
for activation. The control mode is activated when the grid voltage is above the lock-in threshold and deactivated when
the grid voltage is below the lock-out threshold. The threshold for activation must be larger than or equal to the
threshold for deactivation. If this control mode shall always be available, set
lock_in_PPF
=
lock_out_PPF
= 90%
(only available if control mode 6 has been selected in the parameter
ModeSelect
).

PF(U) - Power Factor as a Function of Grid Voltage
This control mode uses the grid voltage to generate a reference value for the power factor (PF) so that the grid voltage
can be controlled at the point of common coupling (only available if control mode 7 has been selected in the
parameter
ModeSelect
).
