AB phase feedback signal doesn’t have parameters to set; it is motor encoder signal 1:1 
output, 2500 pulse/circle. 
 
 
 
5-12. I/O signal distribution 
5-12-1. Input signal distribution 
Parameter range: P5-10~P5-25 
00: no meaning 
y: 0 always open 
 1 always close 
x:  input  terminal 
no. 
Not distribute to terminal 
input 
Input  always  open  signal 
from SIx 
Set  the  signal  to  be  always 
valid 
Input  always  close  signal 
from SIx 
Note: if the distributed terminal has other signal, set the signal to other terminal or set to unused. 
 
Example: take the input signal /CLR (P5-24) of DS2-21P5-AS as an example to explain 
the terminal distribution. 
 
 
 
 
 
Wiring example of input signal 
Clear the pulse offset at the moment of SI2 and 
0V pass through 
Clear the pulse offset at the moment of SI2 and 
0V cut off 
Note: the default input of SI1 is /SON, make sure to distribute P5-10(/SON) to other terminal or set to 
unused. 
DS2-21P5-AS:  CN0-11  is  +24V  terminal,  CN0-7  is 
SI1 terminal. For the example, distribute /CLR signal 
to SI1.
