Operation selection function parameters

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.

[Cooling]

+X>0 Set point

- X<0

CAUTION

*1.The power supply must be selected in accordance with the power specifications of the detector used.

*2.The output signal terminals used depends on the Pr. 64, Pr. 65 settings. *3.The input signal terminal used depends on the setting of Pr. 60 to Pr. 63.

•The contact input signal (AU Signal) need not be turned on.
