* 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.

When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications of terminal 2 when connecting it
to terminal 10E.
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.
Set the voltage/current input switch in the ON position to select
current input (0 to 20mA).
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the
maximum output frequency at 20mA 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 from among
input 4 to 20mA (initial setting), 0 to 5VDC, and 0 to 10VDC. Set
the voltage/current input switch in the OFF position to select
voltage input (0 to 5V/0 to 10V).
functions.
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal
2 or 4 frequency setting signal. Use Pr. 73 to switch between the
input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Common terminal for frequency setting signal (terminal 2, 1 or 4)
and analog output terminal AM and CA. Do not earth (ground).
1 changeover contact output indicates that the inverter protective
function has activated and the output stopped.

Switched low when the inverter output frequency is equal to or
higher than the starting frequency (initial value 0.5Hz). Switched high
during stop or DC injection brake operation.
Switched low when the output frequency reaches
within the range of ±10% (initial value) of the set
frequency. Switched high during acceleration/
deceleration and at a stop.
Switched low when stall prevention is activated by the
stall prevention function. Switched high when stall
prevention is cancelled.
Switched low when an instantaneous power failure
and under voltage protections are activated.
Switched low when the inverter output frequency is
equal to or higher than the preset detected frequency
and high when less than the preset detected
frequency.
