Analog input selection

The functions to switch the analog input terminal specifications, override function, forward/reverse rotation by the input
signal polarity are selectable.

Analog input specification selection
• Concerning the 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 parameters (Pr.73, Pr.267) and voltage/current input switch
settings (switches 1, 2).

• Change the setting of the voltage/current input selection switch to change the rated specification of terminal 2 or 4.
• Correctly set Pr.73, Pr.267 and voltage/current input switch settings so that the analog signal appropriate for the settings is
input. The incorrect settings shown in the table below cause a failure. Other incorrect settings result in an incorrect
operation.

NOTE
• Check the voltage/current input switch number indication before setting, because it is different from the FR-A700 series
switch number indication.

For voltage input, the input resistance is 10±1 kΩ and the
Terminal 2
maximum permissible voltage is 20 VDC.
For current input, the input resistance is 245±5 Ω and the
Terminal 4
maximum permissible current is 30 mA.
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).
