Operating Instruction - Frequency Inverter 230V / 400V ... - opis.cz

16.3 Technology ControllerThe technology controller, the behavior of which corresponds to a PI controller, isavailable as an additional function in configuration 111 and 411. The connection ofreference and actual value of the application with the functions of the frequency inverterenables process control without further components. In this way, applicationssuch as pressure, volume flow or speed control can be implemented easily.The configuration of the reference percentage source and the assignment of the actualpercentage source are to be considered.Structural image:Technology controllerReferencepercentage source 476-Actual percentage source 478Actual values:Actual percentage value 230Reference percentage value 229For the reference value, the technology controller also demands the assignment of ananalog application value with the parameter Actual Percentage Source 478. The differencebetween reference and actual value is used by the technology controller tocontrol the drive system. The measured actual value is mapped via a signal converteronto the input signal of the reference percentage source.Operation mode1 - Analog Input MFI1A32 -Rep.
