ຕັ້ງຄ່າ
- Mounting the Servo: Secure the servo unit to your RC model's chassis using the provided mounting hardware. Ensure it is firmly attached to prevent movement during operation.
- Connecting the Servo Arm: Select the appropriate servo arm for your application and attach it to the servo's output shaft. Use the small screw provided to secure the arm.
- ການເຊື່ອມຕໍ່ໄຟຟ້າ: Connect the servo's three-wire cable to the corresponding channel on your RC receiver or flight controller. The standard color coding is typically: Brown/Black (Ground), Red (Positive Voltage), Orange/Yellow/White (Signal). Ensure correct polarity.
- ການສະຫນອງພະລັງງານ: Connect your receiver/flight controller to a suitable power source (e.g., battery eliminator circuit (BEC) or dedicated servo power supply) that provides the recommended operating voltage (6.0V-8.4V).

ຄໍາແນະນໍາການດໍາເນີນງານ
The Stemedu 70KG Brushless Motor Servo operates based on Pulse Width Modulation (PWM) signals. The pulse width determines the position of the servo arm.
- Pulse Width Range: 500µs to 2500µs.
- ຕຳແໜ່ງທີ່ເປັນກາງ: 1500µs (typically corresponds to 0°).
- Operating Travel: 270° ± 10° (from 500µs to 2500µs).
- Maximum Operating Travel Angle: 358° ± 10° (from 500µs to 2500µs).
- Rotating Direction: Counter-clockwise (CCW) when pulse width increases from 500µs to 2500µs.

ບໍາລຸງຮັກສາ
- ທໍາຄວາມສະອາດປົກກະຕິ: Keep the servo free from dirt, dust, and debris, especially around the output shaft and mounting points.
- ກວດສອບການເຊື່ອມຕໍ່: Periodically inspect all electrical connections to ensure they are secure and free from corrosion.
- ກວດກາເກຍ: While the gears are durable, occasional inspection for wear or damage is recommended, especially after heavy use or impacts.
- ຫຼີກເວັ້ນການໂຫຼດເກີນ: Do not exceed the servo's specified torque limits, as this can lead to premature wear or damage.
- ການດູແລກັນນ້ໍາ: Although IP68 rated, avoid prolonged submersion in corrosive liquids. After use in wet conditions, wipe the servo dry.
ການແກ້ໄຂບັນຫາ
- ເຊີໂວບໍ່ຕອບສະໜອງ:
- ກວດສອບການສະຫນອງພະລັງງານ voltage and current capacity. Ensure it meets the servo's requirements.
- Verify signal cable connection to the receiver/controller.
- Confirm the receiver/controller is powered on and transmitting signals.
- Inspect for physical obstructions preventing servo movement.
- Erratic Movement or Jittering:
- ກວດເບິ່ງການເຊື່ອມຕໍ່ທີ່ວ່າງຫຼືສາຍໄຟເສຍຫາຍ.
- Ensure the power supply is stable and free from voltage ຢອດ.
- Verify the PWM signal is clean and within the specified range.
- Check for excessive mechanical load on the servo.
- ຄວາມຮ້ອນເກີນ:
- Reduce the load on the servo if it's consistently running hot.
- Ensure adequate airflow around the servo, especially in enclosed spaces.
- ກວດສອບການດໍາເນີນການ voltage is not exceeding the maximum 8.4V.
- Loss of Torque:
- Check for worn or damaged gears. Replace if necessary.
- Ensure the power supply is providing sufficient current.
- Verify the servo is not being continuously stalled against an obstacle.
