
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-F800 Instruction Manual
(Detailed).)

Sink logic is initially set for the FM-type inverter.

Source logic is initially set for the CA-type inverter.
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 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.
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, CA. 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.
