Analog input specification selection
• For terminals 2 and 4 used for analog input, the voltage input (0 to 5 V, 0 to 10 V) and current input (0 to 20 mA) are
selectable. To change the input specification, change the setting of Pr.73 (Pr.267) and the voltage/current input selection
switch (switch 1 or switch 2).
Voltage input (initial status)
Current input (initial status)
• Change the setting of the voltage/current input selection switch to change the rated specification of terminal 2 or 4.
• Set Pr.73 (Pr.267) and the voltage/current input selection switch according to the analog signal input. The incorrect
settings shown in the following table cause a failure. The inverter does not operate properly with other incorrect settings.
Setting causing a failure
ON (Current input)
OFF (Voltage input) Current input
• Check the number of the voltage/current input selection switch before setting, because it is different from the switch number
indicated on the FR-A700 series inverter.

Causes an analog signal output circuit failure in an external device (due to increased loads on the
signal output circuit of the external device).
Causes an input circuit failure in the inverter (due to an increased output power in the analog signal
output circuit of an external device).
For voltage input, the input resistance is 10±1 kΩ and the
maximum permissible voltage is 20 VDC.
For current input, the input resistance is 245±5 Ω and the
maximum permissible current is 30 mA.
