2. د خوندیتوب لارښوونې
Please read and understand all safety instructions before operating the ESC. Failure to do so may result in injury or damage to the product or property.
- کله چې په استعمال کې نه وي، تل د ESC څخه بیټرۍ جلا کړئ ترڅو د ناڅاپي فعالیدو مخه ونیسئ.
- ډاډ ترلاسه کړئ چې ټولې اړیکې خوندي او په سمه توګه موصل شوي دي ترڅو د لنډ سرکټ څخه مخنیوی وشي.
- Do not operate the ESC in extreme temperatures or conditions beyond its specified limits.
- Keep the ESC away from children and pets.
- Never attempt to modify the ESC. Unauthorized modifications can lead to malfunction and void the warranty.
- Be aware of rotating parts (e.g., motor, propeller) when the ESC is powered on.
- Use only compatible batteries (LiPo 2-4S) and motors with the ESC.
3. تنظیم او پیوستون
Follow these steps to properly connect your DF-MODELS 120A ESC to your RC model:
- د موټرو پیوستون: Connect the three 4mm gold connectors from the ESC to your brushless motor. The order of connection may affect motor rotation direction; if the motor spins in the wrong direction, swap any two of the three wires.
- د بیټرۍ پیوستون: Connect your LiPo 2-4S battery to the ESC's power input wires, which are equipped with a T-Plug connector. Ensure correct polarity (red to positive, black to negative).
- د اخیستونکي اړیکه: Plug the small signal cable from the ESC into the throttle channel of your RC receiver. The ESC's built-in BEC (Battery Eliminator Circuit) provides 6 volts and 10 amperes of power to your receiver and servos, eliminating the need for a separate receiver battery.
- پورته کول: Securely mount the ESC in your model, ensuring adequate airflow around the unit for optimal cooling.

4. عملیاتي لارښوونې
The DF-MODELS 120A ESC offers standard functions for RC vehicle control:
- فارورډ: Provides power to the motor for forward movement.
- بریک: Applies braking force to the motor. The braking strength is adjustable to 25%, 50%, 75%, or 100% of maximum.
- برعکس: Allows the motor to spin in the opposite direction for backward movement.
Refer to your RC transmitter's manual for throttle calibration and adjustment to ensure proper synchronization with the ESC.
5. ساتنه
Regular maintenance helps ensure the longevity and reliable performance of your ESC:
- پاکول: After use, especially in dusty or wet conditions, gently clean the ESC with a soft brush or compressed air to remove dirt and debris. Ensure the cooling fan is free from obstructions.
- د پیوستون چک: Periodically inspect all wires and connectors for signs of wear, corrosion, or damage. Replace any damaged components immediately.
- ذخیره کول: ESC په وچ او یخ ځای کې د مستقیم لمر وړانګو او سختې تودوخې څخه لرې وساتئ.
6. ستونزه حل کول
که تاسو د خپل ESC سره ستونزې سره مخ شئ، نو لاندې عام ستونزې حل کولو ګامونه په پام کې ونیسئ:
- ځواک نشته: Check battery connection, ensure the battery is charged, and verify the T-Plug connector is fully engaged.
- موټر ځواب نه ورکوي: Ensure the ESC's signal cable is correctly plugged into the receiver's throttle channel. Check motor wire connections. Recalibrate the ESC with your transmitter if necessary.
- موټر په غلط لوري روان دی: د ESC سره وصل شوي درې موټرو تارونو څخه هر دوه یې بدل کړئ.
- د ESC ډیر ګرمیدل: Ensure the cooling fan is operating correctly and free from obstructions. Check for excessive load on the motor or an improperly geared setup.
- موقتي عملیات: Inspect all wiring for loose connections or damage. Check for interference from other electronic devices.
