From KAVAN RC Wiki
Start-up protection: The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time, if the throttle amount is less than 15 %, the ESC will try to restart automatically. If it is larger than 20 %, you need to move the throttle stick back to the bottom position first and then restart the ESC. (Possible causes of this problem: poor connection/disconnection between the ESC and motor wires, propellers are blocked, etc.)
ESC thermal protection: The ESC will gradually reduce the output but won’t cut it off when the ESC temperature goes above 120 °C. To ensure the motor can still get some power and won’t cause crashes, the maximum reduction is about 60 % of the full power. (Here we are describing the ESC’s reaction in soft cut-off mode, while if in hard cut-off mode, it will immediately cut off the power.)
Throttle signal loss protection: When the ESC detects loss of signal for over 0.25 seconds, it will cut off the output immediately to avoid an even greater loss which may be caused by the continuous high-speed rotation of propellers or rotor blades. The ESC will resume the corresponding output after normal signals are received.
Overload protection: The ESC will cut off the power/output or automatically restart itself when the load suddenly increases to a very high value. (A possible cause of sudden load increase is that propellers are blocked.)
Low voltage protection: When the battery voltage is lower than the cut-off voltage set by the ESC, the ESC will trigger the low-voltage protection. If the battery voltage is set to soft cut-off, the battery voltage will be reduced to a maximum of 60 % of the full power. When set to hard cut-off, the output is cut off immediately. After the throttle returns to 0 %, the ESC will drive the motor to sound the alarm.
Abnormal voltage input protection: When the battery voltage is not within the input voltage range supported by the ESC, the ESC will trigger the Abnormal input voltage protection, and the ESC will drive the motor to sound the alarm.
