Figure 5.1: Terminal layout and connection points for the servo driver.
Terminal Descriptions
| Name | Terminal Symbol | Elaboration |
|---|---|---|
| Main loop power supply | R, S, T | Connect external AC power supply: Three-phase AC380V (85%~110%) / 60Hz or Single-phase/three-phase AC220V (85%~110%) 50/60Hz. |
| Brake resistance terminal | P, BK | When connecting external brake resistance, ensure it is used in parallel with the internal brake resistance. Select appropriate resistance value and power to avoid burning out the driver. |
| Motor connection terminal | U, V, W | U: Output to motor U-phase power supply V: Output to motor V-phase power supply W: Output to motor W-phase power supply |
| Ground terminal | or PE | Motor housing ground terminal and Driver ground terminal. Ensure proper grounding for safety. |
After completing all wiring, double-check connections for security and correctness before applying power.
6. Operating Instructions
Once the driver is correctly installed and wired, follow these general steps for operation:
- Power On: Apply the specified AC input voltage (220V, 3/1PH, 50/60Hz) to the main loop power supply terminals (R, S, T).
- System Initialization: Allow the driver to complete its internal initialization sequence. Refer to your specific motor and control system documentation for any required parameter settings or calibration.
- Motor Control: Use the connected control system (e.g., CNC controller, PLC) to send command signals to the servo driver for motor movement.
- Monitoring: Observe the motor's behavior and any indicator lights on the driver for normal operation.
- Power Off: Disconnect power from the main loop power supply when operation is complete or for maintenance.
7. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your servo driver.
- Cleaning: Periodically clean the driver's exterior, especially cooling fins and fan (if present), to prevent dust accumulation and ensure proper heat dissipation. Use a soft, dry cloth.
- Connection Check: Regularly inspect all wiring connections for tightness and signs of wear or corrosion. Re-tighten as necessary.
- Environmental Conditions: Ensure the operating environment remains within specified temperature, humidity, and vibration limits.
- Professional Inspection: For complex issues or internal inspection, consult a qualified technician.
8. Troubleshooting
If you encounter issues with the servo driver, consider the following common troubleshooting steps:
- No Power: Check the main power supply, circuit breakers, and all power connections.
- Motor Not Moving: Verify control signals from the host controller, motor wiring (U, V, W), and ensure no emergency stop is active.
- Overheat Error: Check for proper ventilation, clean cooling fins, and ensure ambient temperature is within limits. Reduce load if possible.
- Overcurrent/Overvoltage Error: Inspect motor and load for abnormalities. Verify input voltage stability.
- Unstable Operation: Check for loose connections, electrical noise interference, or incorrect parameter settings in the control system.
If the problem persists after basic troubleshooting, contact technical support.
