PID controller (technology controller)

The PID controller can be used for process control. The connection of PID desired set value and PID
real value of the application with the functions of the frequency inverter enables process control with-
out further components. In this way, applications such as pressure, volume flow or speed control can
be implemented easily.
Starting the PID controller: Set one of the following parameters.
Parameters
Reference Frequency Source 1
or
Reference Frequency Source 2
Desired set value for PID controller: Set one of the following parameters.
Parameters
Reference Percentage Source 1
or
Reference Percentage Source 2
For example: analog desired set value at MFI2A.
(
Reference Percentage Source 1
MFI2A")
Set terminal X12.4 as analog input.
Parameters
Operation Mode MFI2
1
MFI1A: Multifunction input at terminal X12.3.
2
MFI2A: Multifunction input at terminal X12.4.
