H : VIA terminal function selection

•Function

This parameter allows you to choose between signal input and contact signal input for the VIA terminal.

[Parameter setting]

	Title	Function	Adjustment range	Default setting
			0: VIA - analog input
		Analog/contact input	1: VIA - contact input (Sink)	0
	H	function selection	1: VIA - contact input (Sink)
	H	function selection
		(VIA terminal)	2: VIA - contact input (Source)
			2: VIA - contact input (Source)

*When using the VIA terminal as contact input terminals in sink logic connection, be sure to insert a resistor between the P24 terminal and the VIA terminal. (Recommended resistance: 4.7kΩ-1/2W)

Note: When using the VIA terminal as a contact input terminal, be sure to turn the VIA (SW3) slide switch to the V position.

+The figure on the right shows an example of the connection of input terminal VIA when it is used as contact input terminal. This example illustrates the connection when the inverter is used in sink (Negative) logic mode.
