Depending on the selected mode, only the setting options in the respective
subchapter and these general settings have an effect.
const cos φ
Reactive power default defined by a constant cos φ. The function is limited by the
maximum apparent power and Cos φ minimum, the P/Q priority has no effect.
Parameter Range of val-
ues
Description
"cos φ - Power
Factor"
0 ‑ 1 Set value of Cos φ
"Direction / Ex-
citation"
The current direction corresponds to the
generator counter arrow system.
Over-Excited Over-excited operation = capacitive opera-
tion = reactive power is supplied = reactive
current is fed in lagging the active current.
Under-Excited Under-excited operation = inductive oper-
ation = reactive power is drawn = reactive
current is fed in ahead of the active cur-
rent.
"Time Constant
(τ)"
0.01 s ‑ 60 s Time constant (1 Tau) in seconds [s].
Whenever the set value is changed, this
new set value is not triggered abruptly, but
smoothly in accordance with a PT1 re-
sponse. The time constant describes how
quickly the new set value is reached. (After
three time constants the final value 95 %
is reached)
