Yokomo BL-EP6 User manual

Thank you for purchasing BL-EP6 from YOKOMO LTD. Please read the Instruction Manual thoroughly
before you use the product. These operating instructions are designed to ensure that you quickly
become familiar with its features and functions and make full use of this product.
■SAFETY NOTE
●It is not a toy and suitable for users older than 14 years old.
●Never allow water, moisture, oil or other foreign materials to get inside ESC, motor, or on the PC Boards. It may damage
the ESC completely.
●Never disassemble the ESC and modify the components on the PC Boards.
●Suggest using the original wires and connectors which are packed in the box.
●Never solder one part for more than 5 seconds as some components will get damaged by high temperature.
●Never run the ESC w/o load at full throttle and it may damage the bearings and other moving parts.
●Please make sure the location where to fix the ESC has good airflow ventilating so that the heat could dissipate quickly.
●To avoid short circuit, please keep the ESC connectors far away from other metal parts.
●Never connect the battery in polarity in reverse.
●Please remove the pinion gear before performing calibration and programming functions with this system. Please keep
your hands, hair, cloth, clear from the gear train and wheels of an armed high performance
●Before you switch on the ESC, please make sure all the cables are well solder with the connectors (It is easy to get loose
when running) . What's more, make sure the cables not touch the moving parts.
●Electronic motor timing will increase the temperatures of ESC and brushless motor. Use extreme caution when setting
up and testing your application to avoid overloading and overheating.
●Incorrect timing setting may cause permanent damage to the ESC and motors. Please choose proper ratio and timing
setting according to motor's instruction.
●To avoid signal interference, please always turn on the transmitter first THEN turn on the speed control. Do the opposite
when powering it off.
●Never use faulty accessories, e.g. motor which may damage the ESC. Always insulate exposed wiring with heat shrink
tubing or electrical tape to prevent short circuits, which can damage ESC too.
●Always disconnect the battery pack from the speed control when not in use to avoid short circuits and possible fire
hazard. When the ESC is switched off, there is still small current and it may cause over discharge of the battery after
some time.
●The ESC can support 4-9 cells NiMH or 2-3 cells LiPo battery.

Note : We will not be responsible for any damage caused by non-compliance with above instruction.

■ESC ON/OFF AND LED INDICATOR
1.ESC ON/OFF: When the ESC is OFF, press the switch once, the red LED will stay on (The factory default motor turbo
timing is 10ｰ), then the ESC is ready to work. When the ESC is on, press and hold the switch for 1 second, the LED will
extinguish and the ESC is OFF.
■How to calibrate the ESC?
1)ESC switch OFF.
2)Connect the ESC to the battery and the motor.
3)Turn on the transmitter.
4)Press and hold the ESC switch for few seconds, the motor will ring long beep once. After that, the red LED will blink the
motor will ring like beep-beep-beep… in a row which indicates it is time to set the neutral position, full throttle and full
brake one by one. You could release the ESC switch now.
5)Keep the throttle trigger in neutral position, press the ESC switch once, the green LED will blink once then extinguish
and the motor will ring beep once which indicates the neutral position has been set.
6)Hold full throttle and press the ESC switch once, the green LED will blink twice then extinguish and the motor will ring
twice like beep-beep which indicates the full throttle has been set.
7)Move the throttle trigger to full brake and hold full brake, press the ESC switch once, the green LED will blink three
times then extinguish and the motor will ring three times like beep-beep-beep which indicates the full brake has been
set.
8)After the calibration is finished, keep the throttle in neutral position, the red LED will stay ON, the ESC and the motor is
ready to work.
CAUTION:
1.After running at full load, the ESC will be very hot. In this case, please turn off the ESC after it cools down.
2.When the motor is running, the ESC can't be powered off by pressing the switch; when the motor stops working, the ESC
can be powered off. In an emergency, please disconnect the battery to power off the ESC.
3.When the motor is running, keep the trigger of the transmitter to full brake for 4 seconds, the ESC will be off.
■CONNECTION
1)Connect the motor sensor harness to
ESC. Insert the 6 pin connector on the
end of the motor's sensor wires into
ESC's sensor harness socket.
2)Connect Throttle lead to ESC and
other end to the Receiver (Throttle
Channel, Ch2)
3)Connect the motor and the ESC.
4)Connect ESC to batter pack.
*Calibration is necessary for the first use
of the ESC, or whenever used with a
new/different transmitter.
Individual transmitter's signals for full
throttle, full brake and neutral vary.
You must calibrate your ESC so that it
will operate more effectively with your
transmitter. Servo（Ch1）

1.Plan Speed Control Placement
Choose a location for the speed control that is protected from debris. To prevent radio interference, place the speed
control as far away from the radio receiver as possible and keep the power wires as short as possible. Select a location
that has good airflow ventilating. If the ESC gets air flow, it will run cooler; and that means it will be more efficient.
2.Mount Speed Control in Vehicle
Use double-sided tape to mount the speed control in vehicle (do not use CA glue).

Instruction for Program Card
●Turn off the ESC.
●Connect the lead from program card’s 3 pins
connector to the program interface pins of the ESC.
(Please refer ESC’s Instruction Manual for details. The
connection methods for different ESC may varies)
●Turn on the ESC to apply power to both ESC and
Program Card.
●All the current settings will be displayed on the
correspond LEDs.
●Press and release button to move between settings.
●Press and hold button to change the value for that
setting.
●Turn off the ESC and disconnect lead from Program
Card.
■Programming Card
Programming Card allows you to modify the most
commonly used settings in your ESC controller all at the
touch of a single button. No computer needed.
Simply connect the
Programming Card to
the throttle lead of the
controller and power the
programming card as
described below. Click the
button to scroll through
and change the indicated
settings. All the settings will
