Special operation and frequency control
4)Reverse operation
Increases the manipulated variable (output frequency) if deviation X = (set point - measured value) is positive, and
decreases the manipulated variable if deviation is negative.
Set point
5)Forward action
Increases the manipulated variable (output frequency) if deviation X = (set point - measured value) is negative, and
decreases the manipulated variable if deviation is positive.

Pr. 128 = 20
Pr. 183 = 14
Pr. 190 = 15
Pr. 191 = 14
Pr. 192 = 16
∗1
The power supply must be selected in accordance with the power specifications of the detector used.
∗2
The used output signal terminal changes depending on the Pr. 190 to Pr. 192 (output terminal selection) setting.
∗3
The used input signal terminal changes depending on the Pr. 178 to Pr. 184 (input terminal selection) setting.
∗4
The AU signal need not be input.
