General operating methods of PID control:
(1) Choose the correct transmitter (with the output specification of standard
current signal 4-20mA).
(2) Set the right target value.
(3) If the output does not have oscillation, increase the proportional constant (P).
(4) If the output does not have oscillation, decrease the integral time (Ti).
(5) If the output do not have oscillation, increase the differential time (Td).
(6) Concrete applications can be referred to the example application
descriptions in Appendix 1.
1. Suppress the Over Output
a: Decrease the differential time (D value)
b: Increase the integral time (I value)
2. Suppress the oscillation
a
:
Decrease the differential time (D value) or set it to zero.
b: Decrease Proportional Constant (P value)
The target value can be set through the selection of the panel or external
analog. The external analog is 0~10V signal or given by the potentiometer.
When CD154=0, the target value of PID is the value set by CD153.
When CD154=1,the target value of PID is the value of the external analog 0-10V
(corresponding to 0-100%), the setting of CD153 is invalid.
