EA180 Series Servo Drive Users Manual and 24V power supply, especially when power is supplied to several servo drives or brakes at the same time. Insufficient power supply capacity will lead to insufficient supply current, which may cause damage to the servo drives or brakes. 4) Please note that the brake power supply is 24V DC, and its capacity shall meet the power requirements of the brake. For braking power, please refer to the servo motor description. 5) Confirm correct phase sequence and wiring of the U, V and W output terminals of the servo motor. Wrong wiring may cause the motor to fail to run or run disorderly, thus causing alarm and even motor damage.
6) When an external braking resistor is used, the P+ and D terminals shall be open-circuited, and the resistor shall be connected to the P+ and C terminals. If an internal braking resistor is used, the P+ and D terminals shall be short-circuited and the P+ and C terminals shall be open-circuited (refer to Section 2.7). 7) In single-phase 220V wiring, the main power supply terminals are L1 and L2. If there is an L3 terminal, please do not wire on it. 8) CN2 and CN3 are two communication interfaces with exactly the same definition of pins, and you can use either of them.
