4.2.11 External analog input setting (O, OI, and O2)<br />
The inverter has the following three types of external analog input<br />
terminals:<br />
O-L terminal: 0 to 10 V<br />
OI-L terminal: 4 to 20 mA<br />
O2-L terminal: -10 to 10 V<br />

Using the O2 terminal for auxiliary frequency command (reversible) in addition to the O and OI<br />
terminals<br />
03 Disabling the O2 terminal<br />
Note that whether frequency commands are input to the O2-L terminal and whether the motor operation is<br />
reversible depend on the combination of settings of functions "A005" and "A006" and whether function "16"<br />
(AT) is assigned to an intelligent input terminal as shown in the table below.<br />
When the motor operation is reversible, the inverter operates the motor in a reverse direction if the sum of<br />
the frequencies specified by the main frequency and auxiliary frequency commands is less than 0 (even<br />
when the forward operation [FW] terminal is on). Even when no wire is connected to the 02 terminal,<br />
reverse operation of the motor may occur and prolong the acceleration time if the output voltage fluctuates<br />
near 0 V.<br />
