6.設置と配線
Proper installation and wiring are crucial for the safe and efficient operation of your ESC. Refer to the diagrams below for correct connections.

図2: 角度付き view of the ZTW Beatles G2 40A ESC, highlighting the main power input, three motor phase wires, and the signal wire for receiver connection.
- バッテリーに接続: Connect the red and black power wires of the ESC to your 2-4S LiPo or 5-12NC battery. Ensure the polarity is correct (red to positive, black to negative).
- モーターに接続: Connect the three black output wires from the ESC to the three phase wires of your brushless motor. The order of connection determines the motor's rotation direction. If the motor spins in the wrong direction, swap any two of the three motor wires.
- 受信機に接続します: Plug the signal wire (usually a three-wire servo connector: orange, red, brown) from the ESC into the throttle channel of your RC receiver.
7. Throttle Calibration
Throttle calibration is essential for the ESC to correctly recognize the throttle range of your transmitter. Perform this procedure before the first use or if you change your transmitter.
- Turn on your transmitter and move the throttle stick to its maximum (top) position.
- バッテリーをESCに接続します。ESCからビープ音が連続して鳴ります。
- Wait for the ESC to emit a specific tone indicating it has detected the maximum throttle position.
- Move the throttle stick to its minimum (bottom) position.
- The ESC will emit another series of beeps, confirming the minimum throttle position has been set.
- Disconnect the battery to exit calibration mode.

8. ESCのプログラミング
The ZTW Beatles G2 40A ESC offers several programmable parameters to fine-tune its performance. Programming can be done either via your transmitter or an optional LCD program card.
8.1. Programming via Transmitter
To program the ESC using your transmitter, follow the throttle calibration steps, but instead of disconnecting the battery after setting the minimum throttle, you will enter programming mode. The ESC will emit a sequence of beeps corresponding to different programmable items. Move the throttle stick to select and confirm settings based on the provided programming chart.
参照 ビデオ 1 for a visual guide on programming via the transmitter.
8.2. Programming via LCD Program Card (Optional)
For easier and more precise programming, an optional LCD program card can be used. Connect the ESC's signal wire to the program card, then power the ESC. The program card will display the current settings, allowing you to adjust parameters directly.

9. SMR (Switch Motor Rotation) Function
The SMR function allows for quick reversal of motor rotation. This feature is primarily intended for use when the aircraft is landing on the ground, as it can effectively shorten the landing distance. It is effective only when the throttle is below 50%.

10. メンテナンス
- すべての配線とコネクタに摩耗、損傷、腐食の兆候がないか定期的に点検してください。損傷した部品は直ちに交換してください。
- ESCを清潔に保ち、ほこり、汚れ、湿気を避けてください。清掃には、柔らかく乾いたブラシまたは圧縮空気をご使用ください。
- 過熱を防ぐために、動作中は ESC の周囲に十分な空気の流れを確保してください。
- Store the ESC in a cool, dry place when not in use.
11。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| モーターが始動しない、または止まる。 | Incorrect throttle calibration, motor wires incorrectly connected, signal loss. | Perform throttle calibration. Check motor wire connections; swap any two if rotation is incorrect. Verify receiver connection and signal. |
| ESCが過熱します。 | Insufficient airflow, motor/propeller combination drawing too much current, incorrect motor timing. | Ensure proper ventilation. Use a smaller propeller or a motor with lower current draw. Adjust motor timing settings. |
| モーターが逆方向に動きます。 | モーター配線の接続が正しくありません。 | Swap any two of the three motor phase wires. Alternatively, use the SMR function if applicable. |
| ESC からの応答がありません。 | No power, damaged ESC, incorrect receiver connection. | Check battery connection and charge. Verify ESC is correctly plugged into the receiver. If issues persist, the ESC may be damaged. |
