Control circuit specifications
*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. (For details, refer to page 286.)

Connect this terminal to the power supply common terminal of a
transistor output (open collector output) device, such as a
programmable controller, in the sink logic to avoid malfunction by
undesirable currents.

(voltage)
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).

(current)
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).
* Use Pr. 858 to switch terminal
functions.
