2.4 I/O signal allocation function
Default I/O signal allocation can be changed.
2.4.1 Input signal allocation
Desired input signal can be allocated to any input pin of I/O connector. The logic can be changed.
Some allocation limit is applied to specific signals. Refer to "2.4.1.2 Reallocation of input signal”.
2.4.1.1 Using with the default setting
The table below shows default signal allocation.
Default settings of certain model will differ from those shown below. If the default settings
shown in "REFERENCE SPECIFICATIONS Driver module section (SX-DSV03454)" are
different from values shown below, the settings described in "SX-DSV03454" are valid
default values.

(Note 1) Meaning of a-contact and b-contact:
When the current in the input circuit is shut down and the photocoupler is turned OFF, the allocated function is
disabled (OFF state)
When the current flows through the input circuit and the photocoupler is turned ON, the allocated function is
enabled (ON state)
When the current in the input circuit is shut down and the photocoupler is turned OFF, the function is enabled (ON
state)
When the current flows through the input circuit and the photocoupler is turned ON, the function is disabled (OFF
state)
For the purpose of this specification, the status of the input signal is defined as ON when the signal activates the specified
function and OFF when the signal deactivates the specified function.
And when the photocoupler is turned OFF, time to signal detection becomes long and Variation becomes large.
(Note 2) Axis selection indicates the axis that accepts input signals.
Axis A: Only the Axis A accepts input signals.
Axis B: Only the Axis B accepts input signals.
A or B: Both Axis A and Axis B accept input signals.
