Functions
Window Comparator (Disconnection Detection FVDc/FIDc/FEDc)
•The Inverter activates the window comparator output when the FV/FI/FE analog input value is
within the upper and lower limit levels of the window comparator. This function allows you to
monitor analog input based on the desired level (e.g. to detect a disconnection).

Note: The main circuit DC voltage level, while the function is running, may fall below the b052 set value depending
on the proportional gain and integral time settings.
