PROGRAM THE ESC

FEATURES

Thanks for purchasing our Electronic Speed Controller (ESC). High power system for RC model can

be very dangerous, so please read this manual carefully. In that we have no control over the correct

use, installation, application, or maintenance of our products, no liability shall be assumed nor

accepted for any damages, losses or costs resulting from the use of the product. Any claims arising

from the operating, failure of malfunctioning etc. will be denied. We assume no liability for personal

injury, consequential damages resulting from our product or our workmanship. As far as is legally

permitted, the obligation to compensation is limited to the invoice amount of the aected product.

Note: “Forward/Reverse with Brake” mode and "Foward 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 rst 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 eect of a neutral brushed motor while coasting.

2.3. Low Voltage Cut-O: The function mainly prevents the lithium battery 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 o and the red LED ashes 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 cuto threshold value in the programmable item list is calculated for 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-o 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 cuto threshold by using the Multifunction

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).

Please always keep in mind that the customized value is not for each Lipo battery cell, it is for

the WHOLE battery pack.

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

soft start eect, while level9 has a very aggressive start eect. 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

eect as you want. If the motor can not 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 driverline.

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

Dierent value makes dierent 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 eect can be very smoothly.

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 running function, which is suitable for daily training.

At any time when the throttle is located in neutral zone (except in the throttle calibration or

parameters program process), hold the “SET” key for over 3 seconds, the red LED and green LED will

ash at the same time , which means each programmable item has be reset to its default value.

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

Dierent value makes dierent 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 eect can be very smoothly.

2.8. Throttle Neutral Range: Please refer to the following picture to adjust the neutral range as you like.

2.9. Timing: The "timing" item is usable for both sensored and sensorless brushless motors.

Please select the most suitable timing value

according to the motor you are just using.

Generally, higher timing value brings out

higher power output, but the whole eciency

of the system will be slightly lower down.

Note: For ESC rmware later than 091218A, if

the ESC works with a MODIFY moter, please

don't choose timing values larger than 18.75°, otherwise the motor maybe over heat and damaged.

2.10. Over-Heat Protection: If the function is activated, the output power will be cut-o when the

temperature of the ESC or the internal temperature of the sensored brushless motor is up to a

factory-preset value for 5 seconds. When the protection happens, the Green LED will ash.

● When the ESC is over-heat: The Green LED ashes as “☆-, ☆-, ☆-” (Single ash).

● When the motor is over-heat: The Green LED ashes as “☆-☆-, ☆-☆-, ☆-☆-” (Double ash).

Note: The motor over-heat protection function is only available for the sensored brushless motor made

by the same manufacturer of the ESC. For motors made by other manufacturers, this function maybe

not available or the protection point doesn’t match the design of the ESC, please disable the over-heat

protection function in such a case.

● Compatible with all sensorless brushless motors and most of sensored brushless motors such as

LRP, SpeedPassion, Novak, etc.

● Seamlessly change to sensorless working mode when the sensor cable is broken.

● Excellent start-up, acceleration and linearity features.

● Built-in BEC has a powerful output to supply all the electronic equipments.

● Firmware can be updated through an USB adapter on the Multifunction LCD Program Box

(Optional equipment).

● User programmable. Easily programmed with the “SET” button on the ESC and also compatible

with the 3 digital LEDs Program Card and the Multifunction LCD Program Box.

○ 3 running modes (Forward mode, Forward/Reverse mode, Rock Crawler mode)

○ 4 steps of maximum reverse force adjustment.

○ Proportional ABS brake function with 4 steps of maximum brake force adjustment, 8 steps of drag-brake force

adjustment and 4 steps of initial brake force adjustment.

○ 9 start modes (Also called “Punch”) from “very soft (Level 1)” to “very aggressive (Level 9)”.

○ 8 steps of timing adjustment to suitable for all brushless motors.

○ Multiple protection features: Low voltage cut-o protection / Over-heat protection / Throttle signal loss

protection / Motor blocked protection.

1. Connect the ESC, motor, receiver, battery and servo correctly.

A. Sensored brushless motor wiring

When using brushless motor with Hall Sensor，it is necessary to connect the sensor cable to the

“SENSOR” socket on the ESC, and ESC can automatically identify the motor type (sensored or

sensorless) by detecting the signal coming from the SENSOR socket.

WARNING! For sensored brushless motor, the #A, #B, #C wires of the ESC MUST be connected

with the motor wire #A, #B, #C respectively. Do not change the wires sequence optionally!

B. Sensorless brushless motor wiring.

When using brushless motor

without Hall Sensor, the #A, #B, #C

wires of the ESC can be connected

with the motor wires freely (without

any order). If the motor runs in the

opposite direction, please swap any

two wire connections.

Note: For SENSORLESS motor, you

can also set the throttle channel of

your transmitter to the “Reverse”

direction, and then the motor will run oppositely. And please calibrate the throttle range again

after changing the direction of throttle channel. Please keep in mind that this method is ONLY

available for SENSORLESS motor.

ALERT TONES AND LED STATUS

TROUBLE SHOOTING

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 heard: “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 heard: “beep-, beep-, beep-” (there is 2 seconds interval between every “beep-”

tone).

3. The led status in normal running

● Normally, if the throttle stick is in the neutral range, neither the red led nor the green led lights.

● the red led lights when the car is running forward or backward and it will ash quickly when the

car is braking.

● the green led lights when the throttle stick is moved to the top point (end point) of the forward

zone or backward zone.

Trouble Possible Reason Solution

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 )

After power on, the red LED lights,

but motor cannot run

The motor runs in the opposite

direction

The motor stops running while

in working state

The connections of battery pack are not

correct

The switch is damaged

Input voltage is abnormal, too high or

too low.

Throttle signal is abnormal

1) The wire connections between the ESC

and the motor need to be changed

2) The chassis is not suitable for this ESC

The ESC has entered the “Low voltage

protection mode” or the “Over-heat

protection mode”

Check the power connections, replace the

connectors or switch

Check the voltage of the battery pack

Check the transmitter and the receiver,and

check the signal wire connection of your ESC

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.

The red LED ashes means Low voltage

protection, please replace the battery pack

The green LED ashes means Over-heat protection,

please wait for some minutes to cool the ESC

When accelerating quickly, the

motor stops or trembles

When the throttle stick is in the

neutral range, the red LED and the

green LED ashes synchronously

The motor trembles but cannot

start smoothly

1) The battery has a bad discharge

performance

2) The gear rate is too small so the motor

load is too heavy

The motor is a sensored motor, but the

ESCdetects abnormal signal from the

sensor,so it changes to sensorless mode

automatically

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

2) The ESC is damaged

1) Use a better battery

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 rmly connecting the motor with the ESC

2. The Hall sensors in the motor are damaged,

please change the motor

1) Check the connections

2)Contact the dealer for after-sales service

PROGRAM METHODS

1. Program the ESC with LED program box (Optional equipment )

Please refer to the user manual of LED program box.

2. Program the ESC with Multifunction LCD program box (Optional equipment )

Please refer to the user manual of LCD program box.

3. Program the ESC with the SET button on the ESC

Please refer to the instructions at the right side.

Note:

● In the program process, the motor will emit “Beep” tone at the same time when the LED is ashing.

● If the “N” is bigger than the number “5”, we use a long time ash and long “Beep---” tone to

represent “5”, so it is easy to identify the items of the big number.

For example, if the LED ashes as the following:

“A long time ash + a short time ash” (Motor sounds “Beep---Beep”) = the No. 6 item

“A long time ash + 2 short time ash” (Motor sounds “Beep---BeepBeep”) = the No. 7 item

“A long time ash + 3 short time ash” (Motor sounds “Beep---BeepBeepBeep”) = the No. 8 item

And so on.

2. Throttle Range Setting (Throttle Range Calibration ).

In order to make the ESC t the throttle range, you must calibrate it when you begin to use a new

ESC, or a new transmitter, or change the settings such as the neutral position of the throttle stick,

ATV or EPA parameters, etc. Otherwise the ESC can not work properly. There are 3 points need to be

set, they are the “Top point of forward”, the “Top point of backward” and the “Neutral point”.

The following pictures show how to set the throttle range with a Futaba

transmitter.

A. Switch o the ESC, turn on the transmitter, set the

direction of throttle channel to ”REV”, set the

throttle trim to “0”, set the “EPA/ATV” value of throttle

channel to “100%”, and disable the ABS function of

your transmitter.

B. Switch on the ESC when holding the running

button, and release the “SET” key as

soon as possible when the red LED begins to ash.

Note: If you don’t release the “SET” key as soon as the

red LED begins to ash, the ESC will enter the

program mode, in such a case, please switch o the

ESC and re-calibrate the throttle range again from

step A to step D.
