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. (For details, refer to page 155.)
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 inpage 160.)
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 (5V, 10V) 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
2 or 4 frequency setting signal. Use Pr.73 to switch between the
input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Common terminal for frequency setting signal (terminal 2, 1 or 4)
and analog output terminal AM and CA. Do not earth.
