(VFD, PLC, HMI) Filter
VFD Load Filter, VFD Output Filter
MICONinverterfilter is an HMI filter for inverterused to eliminate interfering noise, filtering the input or output to obtain a pure power supply.
The PLC filtercan effectively filter out frequencies at a particular frequency or frequencies outside of that frequency.
What is aninverter filter?
The filter for inverter is used to limit the rate of rising of the inverter output voltage and reduce common mode noise to the motor. In typical applications where DV/DT is limited to 100-500 V//spl mu/s, the resonance frequency of the filter is higher than the switching frequency.
Working Principle of VFD HMI Filter
HMI controls are connected with filters in the standard data-flow way: through input and output ports.
There are three possible ways of VFD HMIfilter connection:
From a filter's output to a control's input – e.g. for displaying an image or a text result.
From a control's output to a filter's input, as data sources – e.g. for setting various parameters in a program with track-bars or check-boxes.
From a control's output to a filter's input, as events – e.g. for signaling that a button has been clicked.
