Protection Functions
| Short Circuit Protection | When triggered, ESC shuts down output and automatically restores after 100ms |
| Stall Protection | Requires throttle return to zero to restore operation after stall detection |
| Voltage Protection | Prevents motor start if battery voltage is below 16V or above 64V (disabled during flight) |
| Temperature Protection | Reduces output power at 125°C, cuts off at 140°C, restores when temperature drops below 80°C |
| Throttle Loss Protection | Cuts power if throttle signal is lost for more than 2 seconds |
| Startup Protection | Shuts down output if motor isn't started within 10 seconds of throttle increase |
Throttle Calibration
Connect motor first, push throttle to maximum, then power up. After hearing two beeps, pull throttle to minimum. A "DO Mi so" sound indicates successful throttle range setting.
