(without any order). If the motor runs in the opposite direction, please swap any two wire connections.
Note: You can use the transmitter to set the throttle channel to the
“Reverse” direction, and then the motor
will run oppositely. Please calibrate the throttle range again after changing the direction of throttle
channel.
2. Throttle Range Setting (Throttle Range Calibration)
In order to make the ESC match the throttle range, you must calibrate it when you begin to use a new ESC, or a
new transmitter, or after changing the settings of the neutral position of throttle channel, ATV or EPA parameters,
otherwise the ESC cannot work properly.
There are 3 points need to be set, they are the top point of
“forward”,” backward” and the neutral point.
The following pictures show how to set the throttle range with a Futaba
TM
transmitter.
Note2: If you don
’t release the “SET” key after the
red LED begins to flash, the ESC will enter the
program mode, in such a case, please switch off
the ESC and re-calibrate the throttle range again
from step A to step D.
3. The LED Status in Normal Running
a) In normal use, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights.
b) The red LED lights when the car is run forward or backward and it will flash quickly when the car is braking.
c) The green LED lights when the throttle stick is moved to the top point of the forward zone (that is: full throttle).
【ALERT TONES】
1. Input voltage abnormal alert tone: The ESC begins to check the input voltage when power on, if it is out of the
normal range, such an alert tone will be emitted:
“beep-beep-, beep-beep-, beep-beep-” (There is 1 second
time 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 time interval between every “beep-” tone).
【PROTECTION FUNCTION】
1. Low voltage cut-off protection: If the voltage of a Lipo battery pack is lower than the threshold for 2 seconds,
the ESC will cut of the output power. Please note that the ESC cannot be restarted if the voltage of each Lipo
cell is lower than 3.5V.
For NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V but lower than 12V,
it will be considered as a 3S Lipo; If it is lower than 9.0V, it will be considered as a 2S Lipo. For example, if the
NiMH battery pack is 8.0V, and the threshold is set to 2.6V/Cell, it is considered as a 2S Lipo, and the
low-voltage cut-off threshold for this NiMH battery pack is 2.6*2=5.2V.
2. Over-heat protection: When the temperature of the ESC is over a factory preset threshold for 5 seconds, the
ESC will cut off the output power. You can disable the over-heat protection function for competition race.
3. Throttle signal loss protection: The ESC will cut off the output power if the throttle signal is lost for 0.2 second.
【PROGRAM THE ESC】
1. Program Method
Note:
In the program process, the motor will emit
“Beep” tone at the same time when the LED is flashing.
If the
“N” is bigger than the number “5”, we use a long time flash and long “Beep---” tone to represent “5”,
so it is easy to identify the items of the big number.
For example, if the LED flashes as the following:
“A long time flash + a short time flash” (Motor sounds “Beep---Beep”) = the No. 6 item
“A long time flash + 2 short time flash” (Motor sounds “Beep---BeepBeep”) = the No. 7 item
“A long time flash + 3 short time flash” (Motor sounds “Beep---BeepBeepBeep”) = the No. 8 item
And so on.
A) Switch off the ESC, turn on the
transmitter, set the direction of throttle
channel to
”REV”, set the “EPA/ATV”
value of throttle channel to
“100%”, and
disable the
“ABS” brake function of
your transmitter.
(
*Note2
)
B) Hold the
“SET” key and then switch on
the ESC, when the red LED begins to
flash, release the key immediately.
(Please check the picture on the right side)
C) Set the THREE points according to the
steps shown in the picture on the right
side.
1) Neutral point
2) End point of forward direction
3) End point of backward direction
D) When the process of calibration is
finished, the motor can be started after
3 seconds.
