Signals
The window comparator function outputs turn ON when You can also monitor each analog
input by comparing it to a threshold value. This feature allows the inverter to detect discon-
nected signal wiring, loss of power at a signal transmitter, etc. When the input is below the set
threshold value, the inverter substitutes the threshold value for the input. The related parameters
are given in the following tables.
The following signal diagram shows the window comparator output generated from input
signals and comparator settings listed along the Y axis.
