No signal input

: When the ESC is connected to the power supply, if the throttle input signal is not 

detected  by  ESC  or  the  throttle  signal  delay  time  exceeds  the  PWM  signal  delay  parameter,  the 

system will identify the ESC as no signal input state, and the current abnormal state will be prompted 

by the flashing status light and the motor beeping at the same time. 

 

 

Abnormal Signal input

: when the ESC is connected to the power supply, if the throttle input signal 

is not within the midpoint range (The factory default setting of midpoint is 1500 us, and the midpoint 

range is within plus or minus 50 us of the midpoint value, which is 1450 us to 1550 us. When the 

throttle is calibrated, the calibration result shall prevail), the system will identify the ESC as abnormal 

signal input state, and the current abnormal state will be prompted by the flashing status light and 

the motor beeping at the same time. 

 

 

Note

: When the signal is in an abnormal state, set the throttle input signal back to the midpoint range to remove 

the fault prompt.

 

 

Part 3. Throttle calibration

 

This ESC system uses the standard receiver channel signal as a reference by default. However, unexpected 

effects may occur due to the differences in the parameter settings of each receiver and its remote controller 

(such as servo output ratio and servo midpoint value, etc.). Calibrate the throttle at this time so that the ESC 

can be adjusted to the signal output of the receiver to achieve the expected effects.

 

 

COOL 9030 is a two-way ESC, so the throttle calibration method is the same as that of the common two-way 

ESC. The specific steps are as follows

 

 

ESC Calibration Method

 

Preparation 

Connect the ESC, motor, battery, and receiver (Bind the receiver with the transmitter 

in  advance,  and  the  receiver  output  must  be  PWM  signal  output.).  Turn  on  the 

transmitter, and keep other devices powered off. 

Step 1 

Push the throttle stick to the highest position and keep it. Then power on the ESC 

and the receiver. The motor will directly beep twice. (If the motor does not emit beep 

sounds, please refer to the following precautions) 

Step 2 

After two beeps, push the throttle stick to the lowest position and keep it. The motor 

will make two beeps again. 

Step 3 

After two beeps, push the throttle stick to the neutral position and keep it. The motor 

will  emit  a  series  of  beep  sound,  indicating  that  the  ESC  throttle  calibration  is 

completed. 

 

Note

: The order of the position of the throttle stick in the above calibration process is "the highest position  - 

the lowest position - neutral position". If the motor does not directly emit beep sounds when the throttle stick 

is placed at the highest position, change the order of the position of the throttle stick to "the lowest position  - 

the highest position - neutral position" for calibration.
