protective function
- Low voltage protection: off by default (can be customized on).
- High voltage protection: prohibit the motor from starting when the power supply voltage exceeds the allowable value.
- Startup protection: If the startup is unsuccessful, the startup current will be limited, and the startup will be restarted automatically.
- Stall protection: If a stall occurs during normal operation (usually caused by external force), try to restart (note that the stall may damage the ESC when the throtor is high).
- Over-temperature protection: When the temperature exceeds 115°C, the maximum output power will be reduced slowly, up to 40% of the full throttle power, and the original power will be restored after the temperature is reduced.
- Over-current protection: limit the peak current and do not exceed the limit value.
- Overload Protection: When an overload is identified on the motor, the maximum throttle is limited to protect the powertrain.
- Loss of control protection: 200ms after the loss of signal gradually reduce the output power, in 1~2 seconds for rapid throttle reduction to less than 50%, and then slowly reduce the throttle to stop.

About the model
- Default Mode: PWM+CAN (ESC can be used in either PWM mode or CAN mode)
- In default mode, when using PWM signals for control, throttle travel must be calibrated before first use or when replacing the remote control (throttle signal transmitter).
- Calibration Method: Set the throttle signal to maximum value. Powering on will initiate throttle calibration. After 3 seconds, the motor will emit a “♪123 3—” tone.3-3-3 Immediately after this, adjust the throttle signal to its minimum value. The motor will emit the musical tone “♪3-3-5-4”. Once the tone concludes, the throttle travel calibration is complete.正完成。
- In default mode, when using CAN signals for control, refer to the “CKESC-UAVCAN2.1” protocol for ESC control commands.
Safety Notice
- Signal pulse width and frequency must meet specifications. Do not pull or plug/unplug control signal cables while energized. Ensure ESC signal cables are securely connected without looseness to prevent interference signals causing control abnormalities.
- Fireproof plugs may be used for power connections, but ensure connections are secure (poor connections may cause plug erosion or even power failure). Do not use fireproof plugs for output phase wires, and avoid hot-swapping. Ensure stable power supply voltage (for battery-powered systems, ensure batteries have high discharge rates and good low-temperature discharge performance), otherwise ESC damage may occur.
- Ensure that the ESC heat dissipation is good, ESC long-term work in the high temperature state will accelerate the aging of components, significantly reducing the service life of the ESC.
- Do not short-circuit the output phase line before the residual power of the ESC is exhausted, which may cause damage to the ESC.
- When this product is applied to aircraft, the following matters should be noted:
- Please use a properly configured ESC setup to achieve optimal performance (torque efficiency, power output, and safety). Using mismatched motors, propellers (including non-propeller loads or variable loads), or incorrect voltage may result in suboptimal performance or even damage to the ESC.
- Before each flight, it is recommended to inspect all structural components of the aircraft for any signs of loosening, aging, or damage. Ensure that the mounting screws for the arms and propellers are securely tightened.
- Always use a stable load. If the propeller becomes externally locked, immediately reduce throttle or cut power to prevent excessive locked-rotor current from damaging the ESC.
- It is strictly forbidden to overload the product, otherwise the performance and safety of the product cannot be guaranteed.
- Please do not disassemble and modify the product without authorization, otherwise the performance and safety of use and warranty service cannot be guaranteed.
- Avoid introducing interference into the CAN bus during rest periods.
