7 Detailed Functions
Window Comparator (Disconnection Detection FVDc/FIDc/FEDc)
• The window comparator function generates an output when the FV/FI/FV2 analog input value is
between the set upper limit and lower limit levels, enabling the analog input monitoring at the desired
level to detect a disconnection etc.
• The hysteresis width is provided for the window comparator upper/lower limit level setting.
• You can set upper and lower limit levels and a hysteresis width independently for analog input
terminals FV, FI, and FE.
• The analog input value used when the WCFV/WCFI/WCFE signal is output from an analog output
terminal can be fixed to any value. Set the Analog Operation Level at FV/FI/FE Disconnection
(b070/b071/b072). When set to no, the analog input value will be used "as is."
• The multi-function output signal FVDc/FIDc/FEDc will be output in the same way as the
WCFV/WCFI/WCFE signal, respectively.
