maximum apparent power and by "Cos φ Minimum".

‑
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)
Cos φ (P) - Power dependent Power Factor Characteristic
This function controls the cos φ depending on the momentary effective power
according to a characteristic curve. The characteristic curve is defined by four
data points (1

4). If fewer data points are required, the identical parameters
can be set for two points. The function is limited by the maximum apparent
