*2 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 switch ON (current input is selected) or applying 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

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 1 for terminal 2 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 2 for terminal 4 in the OFF
position to select voltage input (0 to 5 V / 0 to 10
*2
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.
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.
