Changing the input signal logic
The inverter provides two types of input signal logics: sink input and source input.
When the “PLC” and “12 V” terminals are short-circuited, sink input is available. When the “PLC”
and “G” terminals are short-circuited, source input is available.
The inverter has been set for sink input before shipment.
The following description is provided on the assumption that the inverter has been set for
sink input.
1) Sink
input
This logic indicates that a signal turns ON when a current flows out of an input terminal.
“G” is the common terminal for input signals.
2) Source input
This logic indicates that a signal turns ON when a current flows into an input terminal.
“12 V” is the common terminal for input signals.
