 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.

Voltage input Causes an analog signal output circuit failure in an external device
(due to increased loads on the signal output circuit of the external device).
Current input Causes an input circuit failure in the inverter
(due to an increased output power in the analog signal output circuit of an external device).

Terminal 2 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
Terminal 4
permissible current is 30 mA.
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.
