Normal mode: Pull the trigger inward for forward operation, and push the trigger forward for backward operation.
There is no brake for the transition between going forward and backward. With low heat, this mode is suitable
to use in confined spaces.
Brake mode: It is the common mode. Pull the trigger inward for forward operation. When the operation of the
trigger is changed from pulling inward to pushing forward, the ESC will perform the brake operation. Return
the trigger to the neutral position currently, and then push the trigger forward again. The ESC will perform the
reverse operation.
Racing mode: Pull the trigger inward for forward operation, and push the trigger forward for brake operation.
There is no reverse operation on ESC.
Climbing mode: Pull the trigger inward for forward operation, and push the trigger forward for reverse operation,
When the trigger is at the neutral position, the ESC will perform the brake operation.
Battery Type
When using different types of batteries, change the state of Jumper cap 3 to make the battery type match the
actual battery. Insert Jumper cap 3 when using a lithium battery, and remove Jumper cap 3 when using a non-
lithium battery. Wrong state of Jumper cap 3 may cause serious over-discharge of the battery and damage the
battery. Be sure to check Jumper cap 3 to confirm the battery type of the ESC before use.
BEC output
Different servos may have different requirements for the working voltage. Change the state of the Jumper cap
4 to select the BEC output voltage. You can choose the appropriate BEC output voltage according to the use
requirements of the connected equipment. Remove Jumper cap 4 when using a common 5V servo, and BEC
will output 5.5V voltage. Insert Jumper cap 4 when using high voltage servo, and BEC will output 7.5V voltage.
Be sure to check Jumper cap 4 to confirm the right BEC output voltage before use. Otherwise, wrong BEC
output voltage selection may damage the servos.
Part 5. ESC status
COOL 9030 ESC has two indicator lights, red and green, to display the current operating status of the ESC.
The power light is used to indicate the current self-check and power supply status of the ESC system, and the
color of the light is green. The status light is used to indicate the current self-check and operating status of the
ESC system, and the color of the light is red. At the same time, the indicator lights have three states: on, off
