4-2 Function Mode 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). 4 Functions •You can set hysteresis widths for the window comparator upper and lower limit levels. •You can set limit levels and a hysteresis width individually for FV, FI, and FE inputs. •For the WCFV/WCFI/WCFE output, you can fix the analog input application value to the desired value.
Set values in FV/FI/FE disconnection operation levels b070/b071/b072. If "no" is set, the analog input value is directly reflected. •FVDc/FIDc/FEDc outputs are the same as WCFV/WCFI/WCFE, respectively. 4-63 Parameter No. Function name Data Default setting Unit C021 to C025 Multi-function output terminals P1 to P5 selection 27: FVDc (analog FV disconnection detection) 28: FIDc (analog FI disconnection detection) 29: FEDc (analog FE disconnection detection) 54: WCFV (window comparator FV) 55: WCFI (window comparator FI) 56: WCFE (window comparator FE) C026 Relay output (MA, MB) function selection 05 b060 (FV) Window comparator FV/FI/FE upper limit level Set an upper limit level.
