Chapter 3 Wiring
This chapter details the wiring method of servo drive, the definition of each signal and
standard wiring diagram.
3.1 Wiring of Delta’s Servo System
3.1.1 Wiring Diagram of Peripheral Devices (connect to Delta’s Servo
Motor (Communication Type))
Installation Notes:
1. Check if the power and wiring among R, S, T and L1c, L2c are correct.
2. When connecting to Delta’s 20bit rotary motor, please 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 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.
