Adaptive logic board for variable speed drive of heating, ventilation, air conditioning and refrigeration systems

An adaptive logic board for variable speed drive. A HVACamp for heating, ventilation, air conditioning and refrigeration; an adaptive logic board (100) of a variable speed drive (52) VSD of an R system includes a signal sensing circuit (154) configured to receive an input signal from a sensor (120, 130) of the VSD. The signal sensing circuit includes a filter (190) configured to regulate the input signal. The filter includes a variable resistive element (184) configured to adjust a cutoff frequency of the filter. The filter is configured to attenuate a waveform in the input signal having a frequency exceeding the cutoff frequency to generate an adjusted signal. The adaptive logic board further includes a controller (164) configured to receive the adjusted signal and to receive the adjusted signal based on the HVACamp; a parameter of the R system adjusts the variable resistive element to adjust the cut-off frequency of the filter. 用于变速驱动的自适应逻辑板。一种用于加热、通风、空气调节和制冷HVAC&R系统的变速驱动(52)VSD的自适应逻辑板(100)包括配置成从所述VSD的传感器(1
