Protection Mechanisms
1. Undervoltage Protection
- The ESC enters a protection state if the supply voltage falls below the set threshold.
- Output resumes once the voltage stabilizes.
2. Overvoltage Protection
- If the input voltage exceeds the set threshold while idle, the ESC enters protection mode.
- If the motor is running, an alarm notification is triggered instead.
3. Throttle Detection
- Ensures throttle loss detection and return-to-zero detection for added safety.
- Audible alarm triggers upon failure.
4. Sensor Zero-Point Detection
- The ESC automatically detects phase current zero points upon startup.
5. Overtemperature Protection
- If the ESC temperature reaches 90°C, it limits input current based on temperature.
- At 100°C, the system reduces output throttle to prevent overheating.
6. Communication Protocol
- Uses IG-UART_V1.2 at 19200 baud rate, with periodic data broadcasting every 255ms.
Control Signal Standard
- Compatible with Aircraft Model Remote Controllers.
- Supports 50Hz frequency cycle, with high-level times from 1150 to 1950µs.
- Telecontrol signal is optically isolated for enhanced safety.
Throttle Calibration Steps
- Connect ESC PWM signal to the receiver.
- Turn on the remote control and set the maximum throttle position.
- Power on the ESC; confirmation tones indicate successful detection.
- Set the throttle rocker to the preset starting position.
- Confirmation tones indicate maximum and minimum throttle calibration.
- Turn off power to save settings.
Connection Description
