Set Pr.73, Pr.267, and the voltage/current input switch correctly, then input an analog signal in accordance with the setting.
Applying a voltage with the voltage/current input switch ON (current input is selected) or a current with the switch OFF (voltage input is selected)
could cause component damage of the inverter or analog circuits of output devices. (For the details, refer to the FR-A800 Instruction Manual
(Detailed).)

Terminal function description
When connecting the frequency setting potentiometer at an initial
status, connect it to the terminal 10.
Change the input specifications of the terminal 2 in Pr.73 when
connecting it to the terminal 10E.
Inputting 0 to 5 VDC (or 0 to 10 V, 0 to 20 mA) provides the maximum
output frequency at 5 V (10 V, 20 mA) and makes input and output
proportional. Use Pr.73 to switch among input 0 to 5 VDC (initial
setting), 0 to 10 VDC, and 0 to 20 mA. Set the voltage/current input
switch in the ON position to select current input (0 to 20 mA).
Inputting 4 to 20 mADC (or 0 to 5 V, 0 to 10 V) provides the maximum
output frequency at 20 mA and 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 among input 4 to 20 mA (initial
setting), 0 to 5 VDC, and 0 to 10 VDC. Set the voltage/current input
switch in the OFF position to select voltage input (0 to 5 V/0 to 10 V).
Use Pr.858 to switch terminal functions.
Inputting 0 to 5 VDC or 0 to 10 VDC adds this signal to terminal 2 or
4 frequency setting signal. Use Pr.73 to switch between input 0 to 5
VDC and 0 to 10 VDC (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).
For receiving PTC thermistor outputs.
When PTC thermistor is valid (Pr.561  "9999"), the terminal 2 is not
available for frequency setting.
For connecting a 24 V external power supply.
If a 24 V external power supply is connected, power is supplied to the
control circuit while the main power circuit is OFF.
