Protection Functions
| Short Circuit Protection | Automatically shuts down output when short circuit is detected. Requires power cycle to restore operation. |
| Stall Protection | Detects motor stalls and requires throttle reset to zero before normal operation can resume. |
| Voltage Protection | Prevents motor start if battery voltage is below 16V or above 80V (disabled during flight). |
| Temperature Protection | Reduces output power to 50% at 125°C and shuts down at 140°C. Normal operation resumes when temperature drops below 80°C. |
| Throttle Loss Protection | Cuts power if throttle signal is lost for more than 2 seconds, restoring power when signal returns. |
| Startup Protection | Shuts down output if motor doesn't start within 10 seconds of throttle increase. Requires throttle reset. |
| Throttle Calibration | Connect motor, set throttle to maximum, power on. After two beeps, set throttle to minimum. Successful calibration is indicated by a "DO Mi SO" tone. |
