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 Instruction Manual (Detailed) of
the FR-A860.)

Terminal function description
When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 using in Pr.73 when
connecting it to 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.
Input 0 to 5 VDC or 0 to 10 VDC to add this signal to the frequency
setting signal input via terminal 2 or 4. 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 the frequency setting signal input via terminal 2
or 4 frequency setting signal (via terminal 2, 1 or 4) for the and analog
output terminal AM. Do not earth (ground).
For receiving PTC thermistor outputs.
When PTC thermistor is valid (Pr.561  "9999"), 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.
