5. 3. 8 Setting PID control
<FPld: PID1 set value>
■ Function
This parameter is applied to process control including keeping airflow, pressure, and the amount of
flow constant.
The set value and the feedback signal (4 - 20 mA, 0 - 10 V) from the detector are compared, and the
frequency is changed toward the set value.
■ Parameter setting
■ Reference of setting
1) Selecting set value and feedback input
Set the set value of PID control with <F389: PID1 set value select> and the feedback input
value with <F360: PID1 feedback input select>.
• For <F389>, do not set the signal used for <F360>.
• When the feedback value and the set value match, the signal can be output. Assign function
"144: PID 1, 2 frequency command agreement" to the output terminals.
