3. Check the LED Status in Normal Running
Ì Normally, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights.
Ì The red LED lights when the car is running forward or backward and it will flash quickly when the car is braking.
Ì The green LED lights when the throttle stick is moved to the top point (end point) of the forward zone or backward
zone.
4. Check the Lipo Cells Setting if You Are Using Lithium Battery
If you are using Lipo battery, we strong suggest setting the “Lipo Cells” programmable item manually to avoid the
over-discharge problem. Please read the instructions on page 6.
In normal case, when the ESC is switched on, the motor will emit several “Beep” tones to express the cells number of
the battery pack. For example, “Beep-Beep-” means 2s Lipo, “Beep-Beep-Beep-” means 3s Lipo, etc.
Alert Tones
1. Input voltage abnormal alert tone: The ESC begins to check the input voltage when power on, if the voltage is
out of the normal range, such an alert tone will be emitted: “beep-beep-, beep-beep-, beep-beep-” (There is 1
second interval between every “beep-beep-” tone).
2. Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone will
be emitted: “beep-, beep-, beep-” (There is 2 seconds interval between every “beep-” tone).
Trouble Shooting
Trouble Possible Reason Solution
After power on, motor doesn’t work,
and the cooling fan doesn’t work
The connections between
battery pack and ESC are not
correct
Check the power connections
Replace the connectors
After power on, motor can’t work,
but emits “beep-beep-, beep-beep-”
alert tone. (Every “beep-beep-” has
a time interval of 1 second )
Input voltage is abnormal, too
high or too low
Check the voltage of the battery pack
After power on, red LED always
lights, the motor doesn’t work
Throttle signal is abnormal Plug the control wire into the throttle
channel of the receiver correctly.
The motor runs in the opposite
direction when it is accelerated
1)The wire connections between
ESC and the motor are not
correct
2)The chassis is different from
the popular design
1) For sensorless motor: Swap any two
wire connections between the ESC and
the motor. Or use the method #2
2) For sensored motor: Please check
the wire connections, they must be A-A,
B-B, C-C respectively. If the connections
are correct, please change the “Motor
Rotation” programmable item to
“CW(Clockwise)”
The throttle signal is lost Check the transmitter and the receiver
Check the signal wire from the throttle
channel of your receiver
The motor suddenly stops running
while in working state
The ESC has entered the Low
Voltage Protection Mode or
Over-heat Protection Mode
Red LED flashing means Low Voltage.
Green LED flashing means Over-heat
When accelerating quickly, the
motor stops or trembles
1) The battery has a bad
discharge performance
2) The gear rate is too small
3) The “Start Mode (Punch)” of
the ESC is too aggressive
1) Use a better battery
2) Use lower KV motor or change the
gear rate
3) Set the “Start Mode (Punch)” to a
softer value
When the throttle stick is in the
neutral range, the red LED and the
green LED flashes synchronously
The motor is a sensored motor,
but the ESC detects abnormal
signal from the sensor, so it
changes to sensorless mode
automatically
1) Check the connection of Hall sensor
cable to make it firmly connect the motor
with the ESC
2) The Hall sensors in the motor are
damaged, please change the motor
