3.2 Classification and function of signal terminals 
3.2.1 Pulse signal 
Open collector (24V voltage) input signal is P+ (pin 3) / D+ (pin 6) 
Input signal of differential mode (5V voltage) is P+ (pin 2) / D+ (pin 5) 
 
The wiring diagram of P + D, CW, CCW and AB phase interface circuit is as follows: 
Open collector (24V voltage) 
PLC, CNC and SCM                      servo driver 
 
Note: 
(1) The supply voltage range of P-/P+24V and D-/D+24V is 18V~25V. If it is below 18V, there 
may be pulse and direction anomalies. 
(2) In order to resist interference, twisted-pair shielding wire must be used. 
 
Differential mode (5V voltage) 
  PLC, CNC and SCM                      servo driver 
 
Note: In order to resist interference, twisted-pair shielding wire must be used. 
 
 
 
When the upper 
device  adopts 
collector  open 
circuit  output, 
use  this 
connection 
method,  please 
pay  attention  to 
suspending  P+ 
5V and D+ 5V. 
When the upper 
device  uses  5V 
differential 
signal  output, 
the  graphic 
connection 
method  is 
adopted,  please 
pay  attention  to 
suspending  P+ 
24V  and  D+ 
24V.
