Set Pr. 73, Pr. 267, 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.

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.
