Protections

Power on safety

If the throttle is not in the neutral position after power on, the motor will emit alarm. The motor can not be started until

protection

the neutral position throttle is detected.

If the voltage is lower than the set low-voltage protection threshold, ESC will automatically reduce the output power

Low voltage

for protection. After running for several seconds, the motor will stops, it can restart when the throttle returned to

protection

neutral position. The above operation can be repeated.

ESC will cut oﬀ output if it fails to start the motor within 3 seconds by accelerating throttle. you need to move the throttle

back to the neutral position and restart the motor.( The possible causes : Bad connection or disconnection between

ESC & motor , propellers are blocked, etc)

When ESC temperature is higher than 100 ℃,it will reduce output power (throttle will be limited below 40%) for protection,

Over heat

make the motor has enough power for return , when the temperature drops to 80℃ , ESC will return to normal working.

ESC detects the loss of throttle signal for over 1 seconds during motor running, it will cut oﬀ output immediately to avoid

an even greater loss caused by the continuous high speed rotation of motor. ESC will return the corresponding output

loss protection

after the signal is restored.

Alarm tone: (To judge the abnormal cases via alarm tone )

1. Alarm of throttle signal is not detected:

ESC detects no signal when power on, motor will emit the alarm tone "B-、B-、B-"(emits every 2 seconds).

2. Alarm of throttle not in the neutral position:

Throttle not in the neutral position, motor will emit "B-B-B-B-" ( urgent short tone).

3. Alarm of voltage out of range:

The ESC detects that the battery voltage is higher than rated voltage when power on, , motor will emit"B-B-, B-B-, B-B-"(emits every 1.5 seconds).

4. Alarm of narrower throttle range:

when throttle range is set too narrow, motor emits "B-B-B-"( urgent short tone, stop after 2 seconds). You must set throttle range again.

Operation instruction

●It is suggested that users should do extra waterproof to get better waterproof eﬀect. If there is water on ESC after use, please dry the

water before use ,in order to avoid damaging the product).

●There is diﬀerent with remote controls , some receivers generate signals when the remote control is not turned on. To avoid injury,

please turn on the remote control ﬁrst and then power on the ESC at any time.

ATTENTION

●

It is recommended to calibrate throttle range for the ﬁrst time

let the ESC acquire and memorize the throttle output signal of the remote control. This operation only needs to be carried out once,

and needs to be repeated when replacing the remote control.

●

Before normal start-up, according to the actual number of battery cells used, it is recommended that the user should select the ﬁxed number of

battery cells via programming. In combination with the low voltage protection, it can eﬀectively prevent the battery from over discharge.

Throttle Range calibration

Note: the following are the diagrams of pistol or stick remote control with neutral position (zero point), which are recommended for Unidirectional

and Bidirectional running modes; in addition, stick remote control without neutral position can be selected for unidirectional operation.

*In some speciﬁc cases, the ESC can work under 2S . For 2S, when the battery voltage is lower than 6V,

Parameter description

1. Running Mode:

[1]Unidirectional(default): It can only move forward, no eﬀect when move the trigger or stick from forward to reverse.

[2]Bidirectional: When move the trigger or stick from forward to reverse, the motor will immediately reverse after it stops running. （The maximum

throttle of forward and reverse is equal)

2.Motor Running Direction:

[1]Normal(default)：Default motor rotation direction；

[2]Reversed：Change the direction of rotation of the motor.

3. Low Voltage Threshold:

[1]No [2]2.6V [3]2.8V [4]3.0V(default) [5]3.2V [6]3.4V

In order to keep the battery at a safe minimum voltage (for LiPo batteries). The ESC monitors the battery voltage all the time, when the voltage goes

below the threshold,ESC will be protected immediately. Please set to "Disabled" if you're using NiMH batteries.

4. Start Acceleration:

[1]Level 1 [2]Level 2 [3]Level 3(default) [4]Level 4 [5]Level 5

It can be adjustable from 1 to 5,set a high value to have a quick start-up response, but requires high discharge capacity of the battery.

5. Motor Timing:

[1]0° [2]3.75° [3]7.5° [4]11.25° [5]15°(default) [6]18.75°

As usual, 15° applies to all the outer rotor motors , but for improving eﬃciency ,recommend that set low timing for 2 poles motor( most inner rotor

motors), set high timing for 6 poles and high poles motors( most outer rotor motors). If need high speed motor, you can set high timing. Some motors

should set special timing, if not sure, you'd better to set timing as motor manufacturer recommended ,or set 15°.

Note: After changing timing, please test on the ground before running.

6.BEC Voltage:

[1]6.0V(default) [2]7.4V

BEC can be selected according to the actual demand.

7.IiPo Cells:

(Available for LiPo battery only)

[1] Auto(default) [2]2S [3]3S [4]4S [5]5S [6]6S .

Auto:The number of battery cells will be automatically determined according to the current voltage every time the ESC is restarted or powered on;

if "Auto" is selected, please always pay attention to the battery voltage to avoid battery over discharge.

2-6s (recommended): Users are advised to select a ﬁxed value according to the actual number of batteries used. With the low voltage protection ,

the battery can be eﬀectively prevented from over discharge.

8.Restore factory default:

When the beeping indicates the "Restore default settings", move the throttle trigger or stick to

under this mode,then motor emits special tone "♪765765" which means default settings are restored.

9.Exit:

When the beeping indicates the "Exit" mode, move the trigger or stick to the neutral position in 3 seconds, then motor emits special tone "♪765765",

it will exit the programming mode.

Speed Up Function

Speed Up Function is suitable for sudden increase of motor rotation speed in the ﬁnal sprint to get faster running speed.

Plug the speed up

function wire

Speed up function eﬀective conditions:

1) It is required that the maximum value of channel shall be greater than 1500us.

2) The setting value of motor timing should be less than 26.25 ° in order to be eﬀective; if the motor timing is set to 26.25 ° then the speed up function

is invalid.

Possible causes

Bad connection between ESC and battery.

Bad soldering cause bad contact.

Low voltage of the battery.

Water got in, damage or other quality

problems with ESC.

ESC doesn't calibrate throttle range.

Bad connection between ESC and motor, or

bad soldering.

Bad motor.

Battery voltage out of range

No throttle signal from receiver.

Throttle trigger or stick doesn't in the
