Input power cord: 16AWG L350 mm

Three-phase output line：16AWG L70 mm

Line number line length： 400 mm

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 16V or higher than 64V, the ESC will sound an alarm and not start the motor. This function will fail 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 beeps of "buzz", then push the throttle to the lowest position. If you hear 1 beep of "Do Mi So", it means the throttle stroke is set successfully.
