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 120°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 PWM mode or CAN mode)
    ①In default mode, if PWM signal is used for control, the throttle travel must be calibrated before first use or replacement of remote control (throttle signal sending device). Calibration mode: Set the throttle signal to the maximum value, turn on the power to start the throttle calibration, after 3s, the motor will emit “♪123 3-3-3-3” After that, immediately set the throttle signal to the minimum value, the motor will emit the music “♪3-3-5-4”, after the music is finished, the throttle travel calibration is completed. The motor will emit music “ ♪3-3-5-4 ”, after the music is finished, the throttle stroke correction is completed.
    ②In default mode, if CAN signal is used for control, the ESC control commands are detailed in the “CKESC-UAVCAN2.1” protocol.

Safety Notice

  • Signal pulse width and frequency must meet the requirements. Don't pull and drag the control signal line, make sure the ESC signal line is connected reliably without loosening, in order to prevent the generation of interference signals leading to abnormal control.
  • The power supply connection can use anti-ignition plug, but make sure the connection is reliable (poor connection will lead to plug ablation and even power failure); do not use anti-ignition plug for the output phase line, and do not plug or unplug it with electricity. Make sure the power supply voltage is stable (if it is battery powered, pay attention to the battery discharge multiplier should be high and the low temperature discharge performance should be good), otherwise it may lead to ESC damage.
  • 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:
    ① Please use a reasonable configuration with the ESC to get the best performance (force efficiency, power, safety). If you use mismatched motors, propellers (not even propeller loads or variable loads) or non-correct voltages, you may not achieve optimal performance or even damage the ESC.
    ② Before each flight it is recommended to check all parts of the aircraft structure for looseness, deterioration or damage, etc. The arm and propeller fixing screws must be locked firmly.
    ③ Be sure to use a stable load, when the propeller is blocked externally, the throttle should be closed or the power should be cut off as soon as possible to prevent the ESC from being damaged by excessive blocking current.
  • 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.
