|---|---|---|
| Motor does not turn after unlocking | Throttle idle value below 1100µs | Set idle throttle to 1160-1180µs |
| Motor turns upon power-on | Throttle locked above 1100µs | Lock throttle to ≤1100µs |
| Beeps every 1.5 sec. yellow flashing | Throttle PWM signal missing | Check signal connection |
| Beeps every 0.5 sec. yellow flashing | High throttle detected | Ensure throttle is low before power-up |
| No sound. yellow LED flashes 4 times per 1.5 sec | Motor loop disconnected | Inspect motor wiring |
| No sound. LED flashes long-short-long-short | Power supply voltage abnormal | Check battery voltage & connections |
| Motor does not start | Short circuit / overcurrent detected | Inspect motor connections & copper terminals |
| LED flashes red/green alternately | PWM throttle signal missing | Check throttle connection |
| LED flashes yellow every 0.2 sec | Hardware issue detected | Inspect screws & cooling system |
