4-2-8. Close-loop control parameters (Group P7)
Analog feedback control system:
Pressure value is input in VI, and feedback value (4～20mA) of pressure sensor is input to inverter CI then pass through
the internal PI adjustor to form analog close-loop control system, as shown in Fig4-32.

Principle diagram of inverter’s internal PI adjustor is shown below:

The definition of close-loop value, feedback value, difference limit and proportion/integral parameter in Fig 4-33 are the
same to normal PI definition. Please refer to P7.01~P7.11. The relationship between preset value and expect feedback val-
ue is shown in Fig 4-34. The preset value is based on 10V; the feedback value is based on 20mA.
The aim of preset value adjustment and feedback value adjustment is to confirm the their relationship and size, as shown in
