9. Basic functions

Analog Frequency setting via Voltage analog input (0-10V) or potentiometer on the VR terminal

Group		LED Display		Parameter Name		Set		Min/Max		Factory	Unit
						Value		Range		Defaults
Drive	0.0			[Frequency command]	-		-		-		Hz
group
		Frq		[Frequency mode]		3	0/8		0
I/O group		I 6	[Filtering time constant for V1 input]		10		0/9999		10
		I 7	[V1 input minimum voltage]		-		0/10		0		V
		I 8	[Frequency corresponding to I 7]		-		0/400		0.0		Hz
		I 9	[V1 input max voltage]		-		0/10		10		V
		I10	[Frequency corresponding to I 9]		-		0/400		60.0		Hz

Select Frq -[Frequency Mode] to 3 {Frequency setting via V1 terminal}.

The 0-10V input can be directly applied from an external controller or a potentiometer (between VR and CM terminals).

Wire the terminal as shown below and refer to page 9-2 for I 6 - I10.

Analog Voltage Input (0-10V)

Frequency Setting via Analog Current Input (0-20mA)

Group		LED Display		Parameter Name		Set		Min/Max		Factory	Unit
						Value		Range		Defaults
Drive	0.0			[Frequency Command]	-		-		-		Hz
group
		Frq		[Frequency Mode]		4	0/8		0
I/O group		I11	[Filtering time constant for I input]		10		0/9999		10
		I12		[I input minimum current]	-		0/20		4		mA
		I13	[Frequency corresponding to I 12]		-		0/400		0.0		Hz
		I14		[I input max current]	-		0/20		20		mA
		I15	[Frequency corresponding to I 14]		-		0/400		60.0		Hz

Select Frq – [Frequency Mode] to 4 {Current Analog Input (0-20mA)}.

Frequency is set via 0-20mA input between I and CM terminals.

See page 9-2 for I11-I15.
