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.

Description
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).
the Instruction Manual (Applied).) Use Pr.
(Refer to Chapter 4 of
858 to switch terminal functions.
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal
2 or 4 frequency setting signal. Use Pr. 73 to switch between the
input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Use Pr. 868 to switch terminal functions.
Common terminal for frequency setting signal (terminal 2, 1 or 4)
and analog output terminal AM. Do not earth (ground).
Description
1 changeover contact output indicates that the inverter
protective function has activated and the output stopped.
Fault: No conduction between B and C (conduction between A
and C)
Normal: Conduction between B and C (No conduction between
A and C)
