Features:
1.Fast response speed, the motor can be completed from idle to full speed in 0.25 seconds
2.Control algorithm specially optimized for disc brushless motors, with higher stability and better compatibility
3.Synchronous freewheeling technology, with better throttle linearity and drive efficiency, and automatic energy recovery when the motor decelerates.
4.Equipped with RPM, error signal output interface
5.Equipped with 485 communication function
Protective function:
1.Voltage protection function: When the ESC is powered on and detects that the voltage is lower than 40V or higher than 105V, the ESC will sound an alarm and not start the motor. This function will be disabled during flight.
2.Temperature protection: When the ESC detects that the temperature is higher than 110°C during operation, an error signal will be output; when the temperature exceeds 140°C, the ESC will shut down the output and return to normal output after the throttle is returned to zero.
3.Throttle loss protection: When the ESC detects that the throttle signal is lost for more than 0.3 seconds, the power output will be turned off. After the signal is restored, the previous power output will be restored.
Throttle stroke setting:
First, connect the motor and ESC, push the throttle to the highest point, then turn on the power and hear 2 "beep" sounds, then push the throttle to the lowest position. If you hear 1 "Do Mi So" sound, it means the throttle stroke is set successfully.

TEST REPORT
Warning sound descriptionFault phenomenon |
Alarm tone |
Possible Causes |
Solution |
The motor cannot start after powering on |
The rapid sound of "beep beep beep" |
Throttle not returned to zero |
Turn the throttle to the lowest point |
The motor cannot start after powering on |
Beep, beep, beep,..." (each interval is 1 second) |
The receiver throttle channel has no throttle signal output |
Check whether the transmitter and receiver cooperate normally; check whether the throttle control channel wiring is normal |
Power-on voltage is lower than 40V |

Battery voltage is too low |
Replace the battery with a suitable fully charged battery |
Power-on voltage is higher than 105V |
"Beep", "Beep", (each interval is 1 second) |
Battery voltage is too high |
Replace the battery with a suitable fully charged battery |
