Functions
Window Comparator ( WCFV/WCFI) (Disconnection Detection FVdc/FIdc)
The Inverter activates the window comparator output when the FV/FI analog input value is
within the upper and lower limit levels of the window comparator. Analog inputs such as
disconnection detection can be monitored on a desired level.
Hysteresis widths can be set for the window comparator upper and lower limit levels.
Levels and hysteresis widths can be set separately for individual FV/FI inputs.
The analog value to be adopted upon WCFV/WCFI output can be fixed to a desired value. Set
values in FV/FI Disconnection Operation Levels (b070/b071). If "no" is set, the analog input
value will be directly reflected.
FVdc/FIdc outputs are the same as WCFV/WCFI, respectively.
Note: The window comparator upper/lower level settings have nothing to do with the external frequency
start/end settings.
Set the voltage limits as percentages [%] corresponding to 0 to 10 V, and current limits as
percentages [%] corresponding to 0 to 20 mA.
