5.9 (T) Multi-Function Input Terminal Parameters
5.9.1 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.

Setting causing a failure Operation
Switch setting Terminal input
ON (current input) 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).
OFF (voltage input) 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).
