6.3.3 General-purpose contact output terminals

You can assign functions "44" (MO1) to "49" (MO6) to terminals 11 to 15 (C021 to C025) and the alarm
relay terminal (C026) to use these terminals as general-purpose output terminals for the easy sequence
function. The table below lists the inverter terminal functions and program variables corresponding to the
terminal functions.
When a general-purpose output function is assigned to one of these output terminals, the data stored in
variables "Y (00)" to "Y (05)" or "Yw" can be output to the terminal. If the easy sequence function is
disabled or a program that does not use variables "Y (00)" to "Y (05)" and "Yw" runs, the output terminals
will be ineffective even when functions MO1 to MO6 are assigned to the terminals.
You can also assign functions other than MO1 to MO6 to the output terminals and operate the terminals
for those functions even while a sequence program is running.

6.3.4 General-purpose analog input terminal (O terminal)

You can use the O terminal as a general-purpose analog input terminal. By referencing the data stored in
variable "XA (0)", the data (ranging from 0 to 10000) input via the O terminal can be fetched .
Switching the O terminal to a general-purpose analog input terminal does not require any special setting.
Even when the O terminal is used to input frequency commands, the O terminal can also function as a
general-purpose analog input terminal. Note that the handling of data fetched via the O terminal depends
on the settings made by the [O]-[L] input functions (A011 to A015).
The figure below shows the relationship between the input voltage and the value to be fetched (when the
settings of functions "A011" to "A015" are the defaults).

6.3.5 General-purpose analog input terminal (OI terminal)

You can use the OI terminal as a general-purpose analog input terminal. By referencing the data stored in
variable "XA (1)", the data (ranging from 0 to 10000) input via the O terminal can be fetched.
Switching the OI terminal to a general-purpose analog input terminal does not require any special setting.
Even when the OI terminal is used to input frequency commands, the OI terminal can also function as a
general-purpose analog input terminal. Note that the handling of data fetched via the OI terminal depends
on the settings made by the [OI]-[L] input functions (A101 to A105).
The figure below shows the relationship between the input current and the value to be fetched (when the
settings of functions "A101" to "A105" are the defaults).
