Power of the node as a percentage of the maximum power.
For the 1st node, the power must be 0%; for the last node, the power
must be 100%. The power values of the nodes must increase continu-
ously.

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.
Settling time
1 – 120 [s]
Settling time in the event of an abrupt change in the reactive power tar-
get value (e.g. caused by a voltage jump). The transient behaviour cor-
responds to a first-order filter (PT-1) with transient time = 5 Tau.
NOTE: The settling time is overlaid with the increasing and decreasing
gradient.

Downtime
0-10000 [ms]
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 re-
active 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 transient time determines the transient behaviour.

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 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.
