ASDA-A2  Chapter 3  Wiring 
Revision February, 2017    3-15 
Installation Notes: 
1.  Check if the power and wiring among R, S, T and DC24V, DC0V    are correct. 
Please refer to Chapter 11 for Specifications. Make sure the input voltage is correct, or it might 
damage the servo drive or danger may occur. 
2.  Check if the output terminal U, V, W of the servo motor is correctly wired. The incorrect wiring 
may disable the operation of the motor or cause the malfunction. 
3.  When applying to the external regenerative resistor, the contact between P  and D should be 
opened and the external regenerative resistor should connect to terminal P  and C. When 
applying to the internal regenerative resistor, the contact between P  and D should be closed 
and the contact between P  and C should be opened. 
4.  When an alarm occurs or the system is in emergency stop status, use ALARM or WARN to 
output and disconnect the power of magnetic contactor in order to disconnect the power of 
servo drive.
