ASDA-B3 Wiring 3.1.2 Connectors and terminal blocks 3 Pay special attention to the following when wiring: 1. When the power is off, do not touch R, S, T, U, V, W, P , D, C, and since the capacitance inside the servo drive can still contain a dangerously large amount of electric charge. Wait until the charging light is off. 2. Separate R, S, T and U, V, W from other wires. The separation should be at least 30 cm (11.8 inches). 3. When using RS-485, use the shielded twisted-pair cable to ensure the communication quality. 4. When selecting the wires, refer to Section 3.1.6. 5. Do not use any external capacitor, or it might damage the servo drive.
3-5 Symbol Name Description L1C, L2C Power input for the control circuit Connect to single-phase AC power. (Refer to the model specification for the proper input voltage.) R, S, T Power input for the main circuit Connect to three-phase AC power. (Refer to the model specification for the proper input voltage.) U, V, W, FG Motor power connector Connect to the servo motor. Symbol Wire Description color U Red A three-phase main power cable for the motor. V White W Black FG Green Connect to the ground terminal for the servo drive. P , D, C, Regenerative resistor terminal or braking unit Use the built-in resistor P and D contacts are short-circuited, and P and C contacts are left open.
Use an external resistor The resistor is connected to P and C contacts, and P and D contacts are left open. Use an external braking unit Connect the external braking unit to P and of the servo drive. P & D contacts and P & C contacts are left open. Ground terminal Connect to the ground wire for the power and servo motor. CN1 I/O connector (optional purchase) Connect to the controller.
