| Beep Pattern | Issue | Cause | Solution |
| Beep… (every 1s) | Motor won’t start | Throttle signal lost | Check transmitter/receiver; adjust throttle bottom |
| Fast beep-beep-beep | Motor won’t start | Throttle not at zero | Move the throttle stick to the minimum |
| Beep-beep (every 1s) | Motor won’t start | Battery < 16V | Replace or recharge battery |
| Beep-beep (every 1s) | Motor won’t start | Battery > 64V | Use correct battery |
| Beep-beep-beep (every 1s) | ESC overheating | Temperature > 125°C | Allow ESC to cool |
| Beep-beep-beep-beep (1s) | Overload / abnormal startup | Incorrect propeller or overload | Replace propeller or reduce load |
The DRV 40A ESC provides precise throttle control and smooth propulsion for small to mid–sized UAV builds. Using synchronous freewheeling it improves throttle linearity, reduces switching losses, and enhances efficiency during hover, cruise, or rapid acceleration.
Its CAN-based flight-controller communication enables telemetry support, fault signaling, and integrated multi-motor control for more stable and accurate UAV operation.
Temperature Protection
Throttle Loss Protection: Cuts power after 2 seconds of signal loss and resumes when signal returns.
Startup Protection: Disables output if the motor does not start within 10 seconds until throttle is reset.
It supports batteries ranging from 5S to 14S LiPo.
Yes, the ESC fully supports CAN and PWM control.
Reasons include the throttle not being at zero, incorrect voltage, or a lost signal.
Power reduces at 125°C and fully shuts down at 140°C until cooled.
No, it requires an external power source for onboard electronics.
Common causes include overload, incorrect propeller selection, or activation of stall protection.
