PARAMETERS
4)Reverse action
Increases the manipulated variable (output frequency) if deviation X = (set point - measured value) is positive, and
decreases the manipulated variable if deviation is negative.
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.

*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. 196 (output terminal selection) setting.
*3 The used input signal terminal changes depending on the Pr. 178 to Pr. 189 (input terminal selection) setting.
*4 The AU signal need not be input.
