6.4.1Setting frequency command characteristics

H	: Analog input/logic input function selection
	: VI/S3 reference point 1 setting (%)		: V1/S3 point 1 frequency (Hz)
H		H
	: VI/S3 reference point 2 setting (%)		: V1/S3 point 2 frequency (Hz)
H		H

• Function

By changing the setting of H, the function of the VI/S3 terminal can be switched between 0~(5)10Vdc voltage input and 4~20mAdc current input. The H to H parameters are used to adjust the output frequency according to the analog signal (voltage: 0~(5)10Vdc, current: 4~20mAdc) from an external device.

■Parameter setting

Title	Function	Adjustment range	Default setting
	Analog input/logic input	0: Voltage signal input (0~10(5)Vdc)	0
H		1: Current signal input (0(4)~20Adc)
	function selection
		2: Contact input
H	VI/S3 reference point 1	0～100(%)	0
	setting (%)
H	VI/S3 point 1 frequency (Hz)	0.0～200.0(Hz)	0.0
H	VI/S3 reference point 2	0～100(%)	100
	setting (%)
H	VI/S3 point 2 frequency (Hz)	0.0～200.0(Hz)	*

Note 1: Do not specify the same value for input points 1 and 2. If you do so, the error message “GTT” will be displayed.

*The value is changed according to the set-up parameter condition. (VFNC1 (S)-□□□□P□-W type)
