2. Programmable Items list
Attention: The italics texts in the above form are the default settings.
3. Programmable Values
3.1. 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 training. The
“Rock Crawler” mode is only used for rock crawler.
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 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 now. When the throttle stick is moved to the backward zone again (The 2
nd
“click”), if the motor speed is
slowed down to zero (i.e. stopped), the backward action will be occurred. The
“Double-Click” method can prevent
mistakenly reverse when the brake function is frequently used in steering.
With
“Rock Crawler” mode, the reverse action will be happened immediately when the throttle stick is moved to
backward zone. Please set the
“Drag Brake Force” to 100% if you choose the “Rock Crawler” mode.
3.2. 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.
3.3. Low Voltage Cut-Off: The function is mainly used to prevent the Lipo battery from over discharging. The ESC
monitors the battery
’s voltage at any time, if the voltage is lower than the threshold, the output power will be
reduced to 50% in 2 seconds. Please drive to the side of racing track as soon as possible and then stop the car,
the ESC will completely cut off the output power in 10 seconds.
3.4. Start Mode (Also called
“Punch”): Select from “Level1 (Soft)” to “Level 9 (Very aggressive)” start mode as
your like. Please note that if you choose
“Level 7” to “Level 9”, you’d better use good quality battery pack with
powerful discharge ability, otherwise these modes cannot get the bursting 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.
3.5. 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.
3.6. Maximum Reverse Force: Sets how much power will be applied in the reverse direction. Different value
makes different reverse speed.
3.7. 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 smooth.
3.8. Throttle Neutral Range: Please see the following illustrations to adjust the neutral range.
3.9. Timing: There are many differences among structures and technical features of different brushless motors; an
ESC with fixed timing cannot be compatible with all brushless motors, so it is necessary to make the timing value
programmable. Please select the most suitable timing value according to the motor you are just using. Generally,
higher timing creates bigger power output, but the whole efficiency of the system will be slightly lower.
3.10. Over-Heat Protection: If the function is activated, the output power will be cut-off when the temperature of
the ESC is higher than a factory preset threshold for more than 5 seconds. When the protection happens, the
Green LED flashes.
4. Reset All Items To Default Values
At any time when the throttle is located in neutral zone (except in the throttle calibration or programming mode),
hold the
“SET” key for over 3 seconds, the red LED and green LED will flash at the same time , which means each
programmable item has be reset to its default value.
【TROUBLE SHOOTING】
Trouble
Possible Reason
Solution
After power on, motor can
’t work, no
sound is emitted
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, motor
can’t work, but
emits
“beep-, beep-, beep-” alert tone.
(Every
“beep-” has a time interval of
about 2 seconds)
Throttle signal is abnormal
Check the transmitter and the
receiver
Check the wire of the throttle
channel
The motor runs in the opposite direction The wire connections between
ESC and the motor need to be
changed
Swap any two wire connections
between the ESC and the motor.
The motor suddenly stops running
while in working state
The throttle signal is lost
Check the transmitter and the
receiver
Check the wire of the throttle
channel
The ESC has entered the Low
Voltage Protection Mode
Replace the battery pack
Random stop or restart or irregular
working state
Some connections are not
reliable
Check all the connections: battery
pack connections, throttle signal
wire, and motor connections, etc.
There
is strong Electro
-
Magnetic interference in flying
field.
Reset the ESC to resume normal
operation. If the function could not
resume, you might need to move to
another area to run the car.
