【TROUBLE SHOOTING】

Trouble Possible Reason Solution

The connections of battery pack are

not correct

Check the power connections, replace the

connectors or switch

The switch is damaged

After power on, the red LED lights, but motor

cannot run

Throttle signal is abnormal

Check the transmitter and the receiver, and check

the signal wire connection of your ESC

1) The wire connections between

the ESC and the motor need to be

changed

2) The chassis is not suitable for this

ESC

1) The battery has a bad discharge

performance

1) Use a better battery

2) The gear rate is too aggresive so

the motor load is too heavy

2) Use lower KV motor or change the gear rate or

set the "Start Mode" more softly

1) Check the connection of Hall sensor cable to

make it firmly connecting the motor with the ESC

2) The Hall sensors in the motor are damaged,

please change the motor

The motor trembles but cannot start smoothly

1) The connctions are not A-A, B-B

and C-C

2) The ESC is damaged

1) Check the connections

2)Contact the dealer for after-sales service

Check the voltage of the battery pack

The motor runs in the opposite direction

1) Swap any two wire connections between the

ESC and the motor. (Note: This method is ONLY

available for SENSORLESS motor )

2) Please don't use the ESC for this special

chassis

When accelerating quickly, the motor stops or

trembles

The motor stops running while in working

state

The ESC has entered the “ Low

voltage protection mode ” or the “

Over-heat protection mode”

The red LED flashes means Low voltage

protection, please replace the battery pack

The green LED flashes means Over-heat

protection, please wait for some minutes to cool

the ESC

After power on, motor doesn’t work, no sound

is emitted

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

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

Note1：When using the firmware with 15 programmable items, the 9

item will be “Boost Timing”. Otherwise the 9

items will be

“Timing”, and 11

to 15

items will be canceled. The factory default firmware is V2.0_100518STOCK (with 15 programmable items).

The optional firmware versions are as follows:

The ESC firmware with 15 programmable items uses Boost Timing and

Turbo technology, which is a great innovation for STOCK racing. For a

standard 11.5T STOCK motor, powered by 2S Lipo battery, when the ESC

applies the maximum timing to the motor, it runs at an incredible speed

more than 110000 RPM, which is much close to the speed of a MODIFIED

motor (While using traditional technology, such a 11.5T STOCK motor

only runs at about 26000RPM).

But the new technology also has some negative impacts; it brings more

power loss and lower efficiency of the whole system. So it is very

important to set the programmable items of your ESC correctly.

Note2：The 11

item is reserved item, with no function.

Note3：Please check the manufacturer’s website to get information about the latest software for XERUN-XTREME STOCK ESC.

2. Explanation For Each Programmable Item

2.1. Running Mode: With “Forward with Brake” mode, the car can go forward and brake, but cannot go backward, this

mode is suitable for competition; “Forward/Reverse with Brake” mode provides backward function, which is suitable for

daily training.

Note: “Forward/Reverse with Brake” mode uses “Double-click” method to make the car go backward. When you

move the throttle stick from forward zone to backward zone for the first time (The 1

“click”), the ESC begins to brake the

motor, the motor speeds down but it is still running, not completely stopped, so the backward action is NOT happened

immediately. When the throttle stick is moved to the backward zone again (The 2

“click”), if the motor speed is slowed

down to zero (i.e. stopped), the backward action will happen. The “Double-Click” method can prevent mistakenly

reversing action when the brake function is frequently used in steering.

By the way, in the process of braking or reversing, if the throttle stick is moved to forward zone, the motor will run forward

at once.

“Forward/Reverse” mode uses “Single-click” method to make the car go backward. When you move the throttle

stick from forward zone to backward zone, the car will go backward immediately. This mode is usually used for the Rock

Crawler.

2.2. Drag Brake Force: Set the amount of drag brake applied at neutral throttle to simulate the slight braking effect of a

neutral brushed motor while coasting.

2.3. Low Voltage Cut-Off: The function mainly prevents the lithium battery pack from over discharging. The ESC

detects the battery’s voltage at any time, if the voltage is lower than the threshold for 2 seconds, the output power will be

reduced 70%, after 10 seconds the output power will be completely shut off and the red LED flashes in such a way:

“☆-☆-, ☆-☆-, ☆-☆-”. Please stop your car at the track side as soon as possible to avoid obstructing other racing cars.

Please note that the cutoff threshold is basically calculated for each LITHIUM (Lipo) battery cell, so for NiMH battery

packs, if the voltage of the whole NiMH battery pack is higher than 9.0V, it will be considered as a 3 cells lithium battery

pack; If it is lower than 9.0V, it will be considered as a 2 cells lithium battery pack. For example, a NiMH battery pack is

8.0V, and the threshold is set to 2.6V/Cell, so it will be considered as a 2 cells lithium battery pack, and the low-voltage

cut-off threshold for this NiMH battery pack is 2.6*2=5.2V.

There are 6 preset options for this programmable item. You can customize the cutoff threshold by using an advanced

LCD Program Box (Optional equipment) to trim it with a step of 0.1V, so it will be more suitable for all kinds of batteries

(NiMH, NiCd, Li-ion, Lipo, LFP, etc).

2.4. Start Mode (Also called “Punch”): Select from “Level1” to “Level9” as your like, Level1 has a very soft start

effect, while level9 has a very aggressive start effect. From Level1 to Level9, the start force is increasing. Please note

that if you choose “Level7” to “Level9” mode, you must use good quality battery pack with powerful discharge ability,

otherwise these modes cannot get the burst start effect as you want. If the motor cannot run smoothly (the motor is

trembling), it may caused by the weak discharge ability of the battery pack, please choose a better battery or increase

the gear rate.

2.5. Maximum Brake Force: The ESC provides proportional brake function. The brake force is related to the position

of the throttle stick. Maximum brake force refers to the force when the throttle stick is located at the top point of the

backward zone. A very large brake force can shorten the brake time, but it may damage the gears.

2.6. Maximum Reverse Force: Sets how much power will be applied in the reverse direction. Different value makes

different reverse speed.

2.7. Initial Brake Force: It is also called “minimum brake force”, and it refers to the force when the throttle stick is

located at the initial position of the backward zone. The default value is equal to the drag brake force, so the brake effect

can be very smoothly.
