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


The power supply must be selected in accordance with the power specifications of the detector used.

The used output signal terminal changes depending on the Pr.190 to Pr.192 (output terminal selection) setting.

The used input signal terminal changes depending on the Pr.178 to Pr.184 (input terminal selection) setting.

The AU signal need not be input.
