9. Basic functions

Frequency setting via Potentiometer on the keypad + Current Analog 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]		5	0/8		0

Select Frq – [Frequency Mode] to 5 {Potentiometer on the keypad and Current Analog input (0-20mA)}. Override function is provided via Main speed and Auxiliary speed adjustment.

Related code: I 1 - I 5, I 11- I 15

When main speed is set via potentiometer and Auxiliary speed via 0-20mA analog input, the override function is set as below.

Group	Code	Parameter Name	Set	Units
			value
I/O group	I 2	[V0 input minimum voltage]	0	V
	I 3	[Frequency corresponding to I 2]	0	Hz
	I 4	[V0 input max voltage]	10	V
	I 5	[Frequency corresponding to I 4]	60.0	Hz
	I 12	[I input minimum current]	4	mA
	I 13	[Frequency corresponding to I 12]	0	Hz
	I 14	[I input max current]	20	mA
	I 15	[Frequency corresponding to I 14]	5.0	Hz

After the above setting is made, if 5V is set via potentiometer and 10mA is applied via I terminal, 32.5Hz is output

Frequency setting via 0-10V + 0-20mA input

Group		LED Display	Parameter Name		Set		Min/Max		Factory	Unit
					Value		Range		Defaults
Drive	0.0		[Frequency Command]	-		-		-		Hz
group
		Frq	[Frequency Mode]		6	0/8		0

Set Frq – [Frequency Mode] to 6 {V1 + I terminal input}.

Related code : I 6 - I 10, I 11 - I 15

Refer to the Frequency setting via Potentiometer on the keypad + Current Analog input (0-20mA) for the setting.
