*1 Set Pr. 73, Pr. 267, and a voltage/current input switch correctly, then input an analog signal in accordance with the setting.
Applying a voltage signal with voltage/current input switch ON (current input is selected) or a current signal with switch OFF (voltage input is
selected) could cause component damage of the inverter or analog circuit of signal output devices.
*2 Refer to Chapter 4 of
the Instruction Manual (Applied).

When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 when connecting it
to terminal 10E. (Refer to Pr. 73 Analog input selection in Chapter 4 of
the Instruction Manual (Applied).)

Inputting 0 to 5VDC (or 0 to 10V, 0 to 20mA) provides the
maximum output frequency at 5V (10V, 20mA) and makes input
and output proportional. Use Pr. 73 to switch from among input 0
to 5VDC (initial setting), 0 to 10VDC, and 0 to 20mA.
Set the voltage/current input switch in the ON position to select
current input (0 to 20mA).

Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA makes input and output
proportional. This input signal is valid only when the AU signal is
ON (terminal 2 input is invalid).
Use Pr. 267 to switch from among input 4 to 20mA (initial setting),
0 to 5VDC, and 0 to 10VDC.
Set the voltage/current input switch in the OFF position to select
voltage input (0 to 5V/0 to 10V).

Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal
