, 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.

Change the input specifications of terminal 2 when connecting it
to terminal 10E.

(voltage)
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).

(current)
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).
