Relationships between deviation and manipulated variable (output frequency)
(3) Wiring example
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. 60 = 14
• Pr. 64 = 15
• Pr. 65 = 16
• Pr. 88 = 20
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.
