This proportional constant is set for the error value gain. In case of I=0, D=0, it
is only for proportional control.
*CD150 Proportional Constant (P)
**
Set Range:0~1000.0% Unit:0.1% Factory Setting:100.0
The integral time (I) is set for the responding speed for PID. The larger the
I value is set the slower the responding speed will be. To the contrary, if the
responding speed is quick but the integral time value is set too small, it will
cause oscillation.
*CD151 Integral Time (T)
**
Set Range:0.1~1000.0S
Unit:0.1S
Factory Setting:.5.0
This differential time (D) is set for the depression operation of PID. The larger
the D value is, the more obvious the depression operation will be. When D is set
to zero, this f unction is invalid.
*CD152 Differential Time (D)
**
Set Range: 0.00~10.00s Unit: 0.01s
Factory Setting: 0
This target value can be set through external voltage signal or the digital
operator.100% target value is corresponding to the analog frequency at +10V.
PID closed-loop control is usually used in the process control with physical
quantity not changing fast, such as the controls of pressure and temperature,
etc. The feedback signal is usually taken f rom temperature transmitter, or
pressure transmitter, etc. Under PID control, the feedback signal input path is
the analog current signal of 4-20mA.
PID closed-loop control is valid when Multi-input PID is started.
