5. Налаштування та встановлення
Proper installation is crucial for optimal servo performance. Follow these general guidelines:
- Монтаж: Securely mount the servo in your RC vehicle or robotic application using the provided screws. Ensure there is no obstruction to the servo's movement.
- Servo Horn Attachment: Select the appropriate servo horn (e.g., 25T) for your application. Attach it firmly to the servo output shaft.
- Електропроводка: Connect the servo's 3-wire cable to your receiver or control board. Typically, the brown/black wire is ground, red is positive voltage, and orange/yellow/white is the signal wire. Ensure correct polarity.
- Джерело живлення: Verify that your power supply voltage is within the servo's operating range (4.8V-8.4V). Overvoltage can damage the servo.
- Початковий тест: Before full operation, perform a basic test to ensure the servo responds correctly to control inputs and moves freely without binding.

6. Інструкція з експлуатації
The Aideepen 40KG servo operates based on Pulse Width Modulation (PWM) signals. The controllable angle range is 0° to 270° with a PWM signal range of 500-2500µs. Ensure your control system (e.g., RC transmitter, microcontroller) is configured to output signals within this range.
- Сигнал керування: The servo's position is determined by the width of the pulse signal. A pulse width of 1500µs typically corresponds to the center position (90°), 500µs to 0°, and 2500µs to 270°.
- Рух: The servo will move to and hold the position commanded by the control signal. If the signal changes, the servo will smoothly transition to the new position.
- Захист від перевантаження: Avoid artificially or mechanically hindering the servo's output shaft, as this can lead to damage or burnout.

7. Технічне обслуговування
Regular maintenance helps extend the lifespan and ensure reliable performance of your servo:
- Gearbox Cleaning: Periodically inspect and clean the gearbox. Apply a small amount of silicone grease to the gears if necessary to reduce friction and wear.
- Дротові з'єднання: Check all wire connections for looseness or damage. Secure any loose connections.
- Монтажні гвинти: Ensure all mounting screws are tight. Vibrations during operation can cause screws to loosen over time.
- Захист навколишнього середовища: While waterproof, avoid prolonged submersion or exposure to harsh chemicals. Clean any dirt or debris from the servo body after use in dusty or wet conditions.
8. Вирішення проблем
Ось деякі поширені проблеми та їх можливі рішення:
- Q1: Why does my high-torque servo buzz?
A: Digital servos often buzz due to constant position correction. To reduce this, ensure no mechanical binding, add a ferrite ring to the signal wire, or switch to analog mode if supported by your system. - Q2: How to maintain for long lifespan?
A: Monthly cleaning of the gearbox (use silicone grease), checking wire connections, and tightening mounting screws are recommended. - Q3: What causes servo jitter and how to fix it?
A: Common causes include electrical interference (keep away from ESCs), bad signal connections (check wiring), or a low-quality transmitter/receiver. - Q4: How to troubleshoot a non-responsive servo?
A: Diagnosis steps include checking voltage with a multimeter, testing with a different receiver channel, trying a known-good servo in the same port, and inspecting for burnt components or unusual smells.
