Chapter 3 Wiring  ASDA-B2 
3-32     Revision May, 2018 
The DI wiring inputs signal via the relay or open-collector transistor. 
Conditions of DI On / Off: 
ON: 15V - 24V; the input current is higher than 3 mA. 
OFF: below 5V; the input current must not be higher than 0.5 mA. 
 
NPN transistor, common emitter (E) mode (SINK mode) 
C9: Wiring of DI signal. The servo drive applies to 
the internal power. 
C10: Wiring of DI signal. The servo drive     
applies to the external power. 
 
 
 
PNP transistor, common emitter (E) mode (SOURCE mode) 
C11: Wiring of DI signal. The servo drive applies 
to the internal power. 
C12: Wiring of DI signal. The servo drive applies 
to the external power. 
 
 
 
 
  Caution: Do not apply to dual power or it may damage the servo drive.
