φ (change by analog input):
With the setting AI
3
φ (change by analog input), the target cos-phi is determined by
means of a configurable curve. The parameters refer to 100% of the analog input (10V
or 20 mA). At the AI module, the channel can be set to voltage input (0–10 V) or current
input (0–20 mA) with DIL switches. The range adaption is made using the parameter “AI
2-10V.” When “AI 2-10 NO” is set, the range is 0–20 mA or 0–10 V.
Cos-phi2 (power recovery) has no function in this mode.
The cos-phi1 (power consumption) is used for the baseline between the adaption ramps.
A hysteresis can be programmed using the “hyst.” parameter.
The transition to the new target cos-phi can be attenuated using the “t-delay” parameter.

Function:
With an input voltage of 0V (= 0%) the instantaneous target-cosφ would be 0.95 ind.
With an input voltage of 5V (= 50%) the instantaneous target-cosφ would be 1.0.
With an input voltage of 10V (= 50%) the instantaneous target-cosφ would be 0.95 cap.
