*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. (For details, refer to page 166.)

Change the input specifications of terminal 2 when connecting it
to terminal 10E. (Refer to page 170 for Pr. 73 Analog input selection.)

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
