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.

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.
