Over-excited | un-

Reactive power mode Under-excited relates to inductive load, over-ex-
cited relates to capacitive load.

Power threshold, function is activated if limit value is undershot.
Lock-in time
0 – 60 [s]
Length of time that the active power must remain below the lock-in
power level before control is deactivated.
Lock-out time
0 – 60 [s]
Length of time that the active power must remain below the lock-out
power level before control is deactivated.

F
Set the intentional delay for the start of the Q(U) function.
NOTE: If the voltage switches from a characteristic curve section with
Q=0 to a characteristic curve section with Q≠0 under active control,
then the reactive power setting process is delayed by the set dead
time. Once the dead time has expired, the control circuit is no longer
subject to a delay and the set settling time determines the transient
behaviour.

ing
In addition to configuring the dynamic behaviour using the transient
time corresponding to a first-order filter, the reactive power setting can
be determined by a maximum gradient - this means the maximum
change in the reactive power per time period.

Min. cos-phi Q1 - Min.
cos-phi Q4
In the event of a significant voltage deviation, the maximum reactive
power adjustment range can be limited by a minimum cos φ factor in
order to prevent an excessive reactive power supply and, as a result, a
significant reduction in the maximum active power that can be fed in.
Q1
Minimum cos φ in over-excited operating mode (in-feed).
Q4
Minimum cos φ in under-excited operating mode (in-feed).
Q2
Minimum cos φ in over-excited operating mode (charge).
Q3
Minimum cos φ in over-excited operating mode (charge).
Priority mode
Q priority | P priority
P priority can be selected as an alternative to the standard setting Q pri-
ority. When it comes to P priority, the reactive power adjustment range
is limited subject to the limited apparent power of the inverter and the
active power that is currently available and fed in.
Active curve
1 – 4
Up to four characteristic curves can be configured independently and
one of them can be activated for regulation each time.
Reset the curve
Reset active curve to the factory setting, depending of the country set-
ting.
Number of nodes
2 – 10
Specify the number of nodes for the Q(U) characteristic curve.
