Attention
Please follow local laws and regulations to legally use this product in flight, and be sure to stay away from people, high-tension lines, and
public places.
This product has strong power and high speed propeller operation with certain safety risks. Users must older than 18 years old and have
relevant professional knowledge.
Do not get close to the motor or propeller that rotates at high speed to avoid being cut.
Before flight, please carefully check that all parts are in good condition, propeller and motor are installed correctly, and screws are not loose.
Features
Quick response. it will take only 0.40 seconds from starting motor to full speed running.
Good compatibility and stability with special control algorithm for disc motors.
Synchronous freewheeling technology can bring better throttle linearity, driving efficiency and automatic energy recovery when lowering
motor
speed.
Have output interfaces of RPM and error signal.
With 485 communication interface, can be real-time communication with flight control. (Note: This function should be matched with flight control)
Convenient installation screw holes without considering ESC part front and back sides.
Protection Function
Over Current Protection
Once checking current is more than 320A and lasts 3 seconds, ESC will shut off power output, and will resume normal after making throttle zero.
Short Circuit Protection
Once checking instant current is more than 450A, ESC will power off, and will rework after trouble shooting and powering again.
Stalling Protection
Motor stall will trigger stalling protection. ESC will resume after making throttle zero and powering again.
Voltage Protection
Once checking voltage is less than 40V or more than 105V, ESC will alarm and will not start up motor. But it will be out of effect during flying.
Throttle Loss Protection
When the detected throttle signal is lost for more than 2 seconds, the ESC will automatically shut down. After the throttle signal is restored,
the ESC will work again
Start Protection
When the motor is not started after increasing the accelerator for 10 seconds, the ESC will automatically shut down. After the accelerator is
reset to zero, and the accelerator is pushed again, the ESC will return to normal.
Throttle Calibration
First connect the motor and turn up the throttle to hihest, then power on, turn down the throttle to lowest when hear the ESC "beep beep" two
times. It indicates the throttle calibration has been set successful when hear the ESC make the sound of "Do Mi So" one time.
Temperature Protection
During flight, if the temperature of the ESC is higher than 125°C, it will generate a fault signal and start reducing the output power to 50% of the
maximum value. If the temperature continues to rise to 140°C, the ESC will turn off the output, and the normal output will not be restored until
the throttle setting is reset to zero. When the temperature drops to 80°C, the maximum output power of the esc starts to rise.
