Hiwonder LX-824HV / LX-224HV High Voltage Bus Servo Instruction Manual

1. Introduction

The Hiwonder LX-224HV and LX-824HV are high-voltage serial bus servos designed for robotics and remote control applications. These servos feature a three-connector design for simplified wiring and operate at 11.1V, which significantly reduces current consumption compared to traditional 7.4V servos. They offer robust performance with metal gears and provide feedback on position, temperature, and voltage to prevent damage.

2. Key Features

• Serial Bus Connectivity: Utilizes serial bus servo connectors for daisy-chaining, simplifying wiring and improving aesthetics.
• High Precision Potentiometer: Provides accurate angle feedback for precise control.
• Reduced Power Consumption: 11.1V operation reduces current by over 60% compared to 7.4V servos, extending service time.
• Protection Features: Supports position, temperature, and voltage feedback to protect the servo from overheating or stalling.
• Dual Operating Modes:
  • Servo Mode: Rotation range of 0-240 degrees.
  • Gear Motor Mode: Continuous rotation range of 0-360 degrees.
• Durable Construction: Equipped with metal gears for extended lifespan and reliability.
• Double-shaft Design: Fixed double-shaft for versatile mounting options.

4. Package Contents

Each servo package includes:

• 1 x LX-824HV / LX-224HV servo (depending on selection)
• 1 x Plastic main servo horn
• 1 x Plastic assistant servo horn
• 1 x Servo wire (20cm)

5. Setup and Wiring

The Hiwonder bus servos are designed for easy integration into your projects, featuring three connection ports for convenient daisy-chaining.

5.1. Physical Installation

The servos are compatible with Hiwonder double-shaft servo frames. Attach the servo to your robot or mechanism using appropriate brackets and screws.

5.2. Wiring

Connect the servos in series using the provided servo wires. The three ports (Right side, Top side, Left side) offer flexibility in wiring layout, ensuring a clean and organized setup.

6. Operation

The Hiwonder bus servos can be controlled via a debugging system or a dedicated servo controller.

6.1. Using the Servo Debugging System (PC Software)

The debugging system allows for detailed configuration and testing of the servos. It supports setting ID numbers, working modes (Servo/Motor), rotation speed, position deviation, LED light control, and various alarm thresholds (temperature, stalling, voltage).

The software provides real-time feedback on current voltage, position, and temperature. It also allows you to manually adjust the servo angle even after power loss.

6.2. Using a Serial Bus Servo Controller

For integrated control, use a compatible serial bus servo controller. This allows for complex movements and coordination of multiple servos, often controlled via a PS2 gamepad or other input devices.

Hiwonder provides control programs for various microcontrollers including 51, Arduino, STM32, and Raspberry Pi.

7. Maintenance

• Regular Inspection: Periodically check all connections for secure fit. Ensure servo horns and mounting screws are tight.
• Cleanliness: Keep the servos free from dust, dirt, and debris, especially around moving parts and ventilation areas.
• Temperature Monitoring: Utilize the temperature feedback feature to ensure servos operate within safe limits, especially during prolonged or heavy use.
• Voltage Monitoring: Monitor input voltage to ensure it remains within the specified 11.1V range to prevent damage.
• Gear Inspection: Although metal-geared for durability, inspect gears for any signs of wear or damage, particularly after impacts or heavy loads.

8. Troubleshooting

• Servo Not Responding:
  • Check power supply connections and ensure adequate voltage (11.1V).
  • Verify serial bus wiring for correct polarity and secure connections.
  • Ensure the servo ID is correctly set and matches the control command.
  • Test with the PC debugging software to diagnose communication issues.
• Erratic Movement or Jitter:
  • Check for loose mechanical connections or damaged gears.
  • Ensure the power supply can provide sufficient current for all connected servos, especially under load.
  • Verify control signals are stable and free from interference.
• Overheating:
  • Reduce the load on the servo.
  • Ensure proper ventilation around the servo.
  • Check for any mechanical binding that might be causing excessive strain.
  • Monitor temperature feedback via the debugging system.
• Stalling:
  • Reduce the load or ensure the mechanism moves freely.
  • Check for obstructions preventing full range of motion.
  • Monitor stalling alarm feedback via the debugging system.

9. User Tips

• When connecting multiple servos, ensure your power supply is robust enough to handle the combined current draw, especially during peak loads.
• Utilize the PC debugging software to fine-tune servo parameters like ID, speed, and position deviation for optimal performance in your specific application.
• Take advantage of the feedback features (voltage, temperature, position) to proactively monitor servo health and prevent potential damage.
• For complex robotic projects, consider using a dedicated servo controller board that can manage multiple servos and simplify programming.
