External Analog Input Setting (O, O2, And Oi) (A005, A006, C001 To C008) - Hitachi SJ700B Series Instruction Manual

Chapter 4 Explanation of Functions
4.2.11 External analog input setting (O, OI, and O2)
The inverter has the following three types of external analog input
terminals:
O-L terminal: 0 to 10 V
OI-L terminal: 4 to 20 mA
O2-L terminal: -10 to 10 V
The table below lists the settings of the external analog input terminals.

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