Example
In the above example, the status of the input terminals X(02) to X(05) is captured and output to the output terminals Y(00) to Y(03).
Yw value
Command Description Argument
Outputs data to the output terminal variable in
units of words.
Reflect each bit in corresponding output.
Value: any variable or constant
Format
Flowchart method Text language method
Yw : <value>
Note The output terminal variable is a variable that controls the status of the inverter's output termi-
nal. The following settings are required. The numerical order of the output terminal variables
follows the numerical order of the set general-output numbers.
Set the Multi-function Output 11 to 13 Selection (C021 to C023) and the Multi-function Relay Output (RY) Func-
tion Selection (C026) to 35 to 41 (MO1 to MO7: General-purpose output).
When the data is assigned in units of words, zero is read out for the upper byte data and unset input terminal
variables. If there is any setting, the setting is ignored.
<Assignment example>
Yw 1 (bit 0) to Y(00) MO1 (multi-function No. 35)
Yw 2 (bit 1) to Y(01) MO2 (multi-function No. 36)
Yw 4 (bit 2) to Y(02) MO3 (multi-function No. 37)
Yw 8 (bit 3) to Y(03) MO4 (multi-function No. 38) (only if expanded I/O for LX is used)
Yw 16 (bit 4) to Y(04) MO5 (multi-function No. 39) (only if expanded I/O for LX is used)
Yw 32 (bit 5) to Y(05) MO6 (multi-function No. 40) (only if expanded I/O for LX is used)
Yw 64 (bit 6) to Y(06) MO7 (multi-function No. 41) (only if expanded I/O for LX is used)

Block number
Operation
1 Assigns the value of Xw (value of input terminal) to U(00).
2 Divides the value of U(00) by 4 (2-bit right shift) to assign X(02) to bit 0.
3
Performs a logical AND operation on U(00) and 15 (binary: 00001111) and changes the bits higher than X(06) to zero.
4 Assigns U(00) to Yw.
5 Jumps to the block 1: loop_ unconditionally.
