Note

: In the above table, the mixed prompt mode of the power light and the status light means that the two 

prompts of system states  are executed simultaneously. The  prompts of power  light and the status light  are 

independent, which means the two prompts of system states can be executed independently. 

 
 

5.3 Mixed prompt of motor and light 

In the mixed prompt mode of the motor sound and indicator light, the red light works, but the green light doesn't. 

At the same time, when there is a battery over-voltage warning or battery under-voltage warning, the system 

state prompt will remove the motor sound prompt, and only retain the indicator light prompt. In the two system 

states  of  system  high  temperature  warning  and  system  low  temperature  warning,  the  time  interval  of  two 

consecutive motor sounds is 1.5 seconds, while in the two system states of throttle signal loss and abnormal 

throttle signal, the time interval of two consecutive motor sounds is 2.5 seconds. 

 

In this ESC system, the system states corresponding to the mixed prompt of the motor sound and indicator 

light are as follows: 

 

Motor sound and red indicator light 

System state 

Four consecutive short beeps 

System high temperature warning 

(Above 85

Flash once every 0.2 second 

Three consecutive short beeps 

System low temperature warning 

(Below -40

Flash once every 0.4 second 

One short beep 

Throttle signal loss 

Flash once every 0.6 second 

Two consecutive short beeps 

Abnormal throttle signal 

Flash once every 0.8 second 

 

Meanwhile, when in the normal operating state mentioned above, the motor will respond to the signal. But in 

other  abnormal  operating  state  mentioned  above,  ESC  will  terminate  the  operation  of  the  motor,  with  no 

response  to  signal  input.  At  this  time,  the  system  can  only  enter  the  normal  operating  state  after  the 

corresponding fault is eliminated.
