2.2 Wiring Diagram
Refer to the following diagram for proper connection of the servo motor and driver. Ensure all connections are secure before applying power.
Figure 2: T3D-L15A/L20A AC Servo Driver Wiring Diagram.
- CN1 (Upper Computer Command Port): Connects to CNC, PLC, or other upper-level control devices.
- CN2 (Motor Encoder Port): Connects directly to the motor encoder.
- CN3/CN4 (RS485 Communication Port): Located on the top of the drive, used for RS485 communication.
- L1/L2 Terminal: Main power input terminal. Connect to a single-phase 220V AC power supply.
- NC Terminal: This terminal should not be connected.
- P/D/C Terminal: Braking resistor connection terminal. P and D are connected together. Use the internal braking resistor.
- N Terminal: Do not connect this terminal. Incorrect connection may cause damage to the drive.
- U/V/W/PE Terminal: These four wires (U, V, W, and PE) of the motor power line must be connected to their corresponding terminals on the driver. Ensure correct polarity and connection to prevent damage.
- CHARGE Indicator: Indicates the drive power status.
2.3 Power Supply
The servo motor kit requires a 220V AC power supply. Ensure the power source meets the specified voltage and current requirements for stable operation.
2.4 Control Signal Cable
The control signal cable is available with an optional 5V or 24V pulse signal selection. Select the appropriate voltage based on your control system's requirements.

5. Troubleshooting
This section outlines common issues and potential solutions for the RWRAPS AC Servo Motor Kit.
| Issue | Possible Cause | Recommended Action |
|---|---|---|
| Under Voltage | Input power supply voltage is too low. | Check the 220V AC power supply. Ensure stable voltage. |
| Over Voltage | Input power supply voltage is too high or regenerative voltage. | Verify the 220V AC power supply. Check braking resistor connection if applicable. |
| Over Load | Motor load exceeds rated capacity. | Reduce the mechanical load or verify motor sizing for the application. |
| Over Current | Excessive current draw, possibly due to short circuit or motor damage. | Inspect motor wiring for shorts. Check motor for damage. |
| Encoder Exception | Encoder cable disconnected or damaged, or encoder malfunction. | Check the encoder cable connection (CN2). Replace cable or encoder if damaged. |
| Position Error | Deviation from target position, often due to tuning issues or external interference. | Review servo tuning parameters. Check for mechanical binding or external forces. |
If these troubleshooting steps do not resolve the issue, contact RWRAPS customer support for further assistance.
