Determines the dynamic behaviour in the event of a change in the cos ϕ
set value. With a change of the active power or the lock-in and lock out
voltage, the cos ϕ is changed according to a PT-1 characteristic curve
with a settling time of 5 Tau.

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.

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.
