z Frequency setting via Potentiometer on the keypad + Current Analog input (0-20mA)

	Group		LED Display	Parameter Name		Set		Min/Max		Factory	Unit

			Frq	[Frequency Mode]		5	0/8		0

ƒ Select Frq – [Frequency Mode] to 5 {Potentiometer on the keypad and Current Analog input (0- 20mA)}.

ƒ Override function is provided via Main speed and Auxiliary speed adjustment. ƒ 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
