QSINK (Negative) logic/SOURCE (Positive) logic (When an external power supply is used)
The PLC terminal is used to connect to an external power supply or to insulate a terminal from other input or output terminals. As for input terminals, turn the SW1 slide switch to the PLC position.

QSelecting the functions of the VIA and VIB terminals between analog input and contact input
The functions of the VIA and VIB terminals can be selected between analog input and contact input by changing parameter settings (H). (Factory default setting: Analog input)
When using these terminals as contact input terminals in a sink logic circuit, be sure to insert a resistor between the P24 and VIA terminals or between the P24 and VIB terminals. (Recommended resistance:
When using the VIA terminal as a contact input terminal, be sure to turn the VIA switch to the V position. If no resistor is inserted or the VIA slide switch is not turned to the V position, contact input will be left always ON, which is very dangerous.
Switch between analog input and contact input before connecting the terminals to the control circuit terminals. Otherwise the inverter or devices connected to it may be damaged.
