• 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).

• 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.

NOTE
• Check the number of the voltage/current input selection switch before setting, because it is different from the switch number
indicated on the FR-F700(P) series inverter.

Description
The terminal 2 input specification (0 to 5 V, 0 to 10
V, 0 to 20 mA) and terminal 1 input specification (0
to ±5 V, 0 to ±10 V) are selectable. Also the
override and reversible operation settings are
selectable.
