If the input voltage is not within the regulated range, it will take the voltage as an abnor-
mal voltage and then activate the protection, ash Red LED and beep a series of beeps.
2. Sta-up Protection
The ESC will monitor the motor speed (RPM) during the sta-up process. When the speed
stops increasing or the speed increase is not stable, the ESC will take it as a sta-up failure.
At that time, if the throttle amount is less than 15%, the ESC will automatically t to resta
up; if it is larger than 20%, then you need to move the throttle stick back to the bottom
position and then resta up the ESC. (Possible causes of this problem: poor connection/
disconnection between the ESC and motor wires, propellers are blocked, etc.) .
3. ESC Thermal Protection
The ESC will gradually reduce the output but won’t cut it o completely when the ESC
temperature goes above 110. For ensuring the motor can still get some power and won’t
cause crashes, so the maximum reduction is about 50% of the full power. The ESC will
gradually resume its maximum power after the temperature lowers down. In addition, the
ESC temperature cannot exceed 70 when it’s powered on. Otherwise, it cannot be staed
up but ashes Blue LED and beeps a series of beeps to indicate the ESC temperature is
too high. (Here we are describing the ESC’s reaction in the “Soft Cuto” mode, while if in
the “Hard Cuto” mode; it will immediately cut o the power.)
4. Throttle Signal Loss Protection
When the ESC detects loss of signal for over 0.25 second, it will cut o the output
immediately to avoid an even greater loss which may be caused by the continuous high-
speed rotation of propeller. The ESC will resume the corresponding output after normal
signals are received.
5. Overload Protection
The ESC will cut o the power/output and automatically resta itself when the load sudd
-enly increases to a ve high value. If the load still remains high or the motor still remains
out of sync, then it will completely cut o the power/output.
6. Low-voltage Cuto Protection
When the operating voltage goes below the preset cuto voltage, the ESC will gradually
reduce the output but won’t cut it o completely. For ensuring the motor can still get
sucient power to land the aircraft safely, so the maximum reduction is about 50% of the
full power. You need to change another fully charged batte to resume the operation
when the low-voltage cuto protection is activated.
7. Over-current Protection
During use, the ESC will cut o the output immediately if the current exceeds the regula-
ted value and then resume it quickly; the ESC will cuto the output completely and won’t
resume it if the regulated value is exceeded again.
