2.2.2. Motor and Encoder Connections
Connect the servo motor and its encoder to the designated terminals on the driver. The encoder is a 2500ppr incremental type.
2.2.3. Communication Port (RS485)
The DS-R bus type drive features two standard RJ45 network interfaces for RS485 communication. Use a shielded twisted-pair or network cable for transmission. Up to 31 drives can be networked.
| Pin | Network Cable Color | Signal Definition |
|---|---|---|
| 1 | White/orange | 485+ |
| 2 | Orange | 485- |
| 3 | White/green | GND |
| 4 | Blue | NC |
| 5 | White/blue | NC |
| 6 | Green | NC |
| 7 | White/brown | NC |
| 8 | Brown | NC |
2.2.4. DIP Switch Settings
The DIP switches on the driver allow adjustment of communication station number and baud rate. For the drive at the end of the bus, set DIP switch SW7 to ON to connect a terminating resistance, preventing signal reflection.
3. Operating Instructions
The DS-R series servo driver supports various control modes including position mode, velocity mode, torque mode, internal 16-segment position, internal 16-segment velocity modes, and built-in 31 standard homing modes. These modes can be configured via the Modbus RS485 communication protocol.
3.1. Communication Control
The driver can be controlled via Modbus RS485 communication. This allows for precise control over motor parameters and movement. The video below demonstrates the connection and basic operation of the servo motor and driver system.

5. Maintenance
To ensure optimal performance and longevity of your Lichuan servo motor and driver, follow these general maintenance guidelines:
- Keep the motor and driver clean and free from dust and debris.
- Ensure proper heat dissipation by maintaining adequate airflow around the components.
- Regularly check all electrical connections for tightness and signs of wear.
- Avoid exposing the equipment to excessive moisture or extreme temperatures.
- If any unusual noises or performance issues occur, consult the troubleshooting section or contact technical support.
6. Troubleshooting
If you encounter issues with your Lichuan servo motor and driver, consider the following common troubleshooting steps:
- No Power: Verify the power supply connections and ensure the input voltage is within the specified range (DC24V-50V for the 100W model).
- Motor Not Moving: Check motor and encoder wiring for correct connections. Ensure communication parameters (station number, baud rate) are correctly set via DIP switches or software.
- Communication Errors: Confirm RS485 wiring, especially 485+ and 485- connections. Ensure the terminating resistor (SW7 ON) is correctly set for the last drive in a multi-drive network.
- Overheating: Check for obstructions to airflow around the driver and motor. Ensure the load on the motor is within its rated torque.
- Unusual Noise/Vibration: Inspect mechanical mounting for looseness. Check motor and encoder connections.
For persistent issues, refer to the detailed driver instruction book or contact Lichuan technical support.
7. User Tips
- Proper Grounding: Always ensure proper grounding of the servo system to prevent electrical noise and ensure safe operation.
- Cable Management: Route power, encoder, and communication cables neatly and separately to minimize interference. Use shielded cables where recommended.
- Software Configuration: Familiarize yourself with the driver's software interface for advanced parameter tuning and mode selection to optimize performance for your specific application.
- Start with Low Speeds: When first testing, begin with low speeds and torques to verify correct operation before increasing to desired performance levels.
