CV3100 series and MINI series high performance general purpose inverter instruction manual
6.7 Process PID control parameter
Analog feedback control system:
Pressure given quantity input through AI1 and 4-20mA signal feedback from pressure
sensor input through AI2 are connected with PID adjustor built-in to compose the
close loop control system, shown as Diagram 6-20:

PID function as followings：
PID gives comparison to the system ration and feedback quantity which was detected
from the sensor to the object controlled, proceeding with operation of proportion,
integral and differential coefficient to their deviation in order to adjust the inverter
output frequency, applying for process control of physical quantity, such as flow,
pressure, temperature and so on, the system network shown as Diagram 6-21:
