Specifications

Instructions

Normal startup procedures

1. Move throttle stick to the bottom position and then switch on transmitter.
2. Connect battery pack to ESC.
3. The long “beep” sound should be emitted, means the bottom point of throttle range has been detected.
4. Several “beep” tones should be emitted to present the amount of battery cells.
5. When self-test is finished, a “♪ 1 2 3” tune should be emitted.
6. Move throttle stick upwards to go flying.

Throttle range setting procedures

(When users change transmitter, throttle range setting is recommended.)

1. Switch on the transmitter, move throttle stick to the top position.
2. Connect battery pack to ESC.
3. Two “beep” sounds should be emitted, means the top point of throttle range has been confirmed and saved.
4. Move throttle stick to the bottom position (within 2s), a long “beep” sound should be emitted, means the bottom point of throttle range has been detected.
5. Several “beep” tones should be emitted to present the amount of battery cells.
6. When self-test is finished, a “♪ 1 2 3” tune should be emitted. Move throttle stick upwards to go flying.

If the throttle stick is neither at the bottom position nor the top position after powered on, it will constantly make “beep” sounds.

If you hold the throttle stick on top position for more than 2 seconds after the top point of throttle range has been confirmed and saved, you will be led to transmitter programming mode.

Programmable Parameters

• D1. Brake Type: six brake types including OFF, Low, Mid-low, Middle, Mid-high and High. Default: OFF.
• D2. Timing Mode: five options: Low: 0°, Mid-low: 8°, Middle: 15°, Mid-high: 23° and High: 30°. Default: Middle: 15°. Low advance timing is recommended for high inductance and low KV motors. High advance timing is recommended for low inductance and high KV outrunner motors. For some high KV motors, if it shakes while rotating in high speed, the High timing mode is recommended.
• D3. Start Force: 13 options: 0.03, 0.05, 0.06, 0.09, 0.13, 0.19, 0.25, 0.38, 0.50, 0.75, 1.00, 1.25, 1.50. Default: 0.75. Select start force according to the load of motor.
• D4. Curve Mode: four options: Off, Low, Middle, High. Default: Off.
• D5. Control Frequency: 2 options: 8KHz and 22KHz. Default: 8KHz. This option is the drive frequency of the motors.
• D6. Low-voltage Protection: 3 options: 2.8V/cell, 3.0V/cell, 3.2V/cell (If there are four options, the fourth option is off the low voltage protection). Default: 3.0V/cell. The system will automatically identify the battery cells.
• D7. Cutoff Mode: two options: Soft-Cut and Cut-Off. Default: Soft-Cut. Soft-Cut option: gradually reduce throttle power to 31% of the current power when the voltage is lower than the programmed low-voltage protection threshold. Cut-Off option: immediate motor shutdown occurs in low-voltage.

When in low-voltage protection, push the throttle stick to the bottom position and then to the top position, the motor will be restarted. But since it is low-voltage condition, the output power is low or stopped at once.

Protection Setting

• E1. Low-voltage Protection: whether to shut down the motor immediately or to lower the power when the input voltage drops below the programmed low-voltage protection threshold depends on the values set as Cutoff Mode. (Please refer to D7 for Cutoff Mode.)
• E2. Loss of Signal Protection: power will be gradually lower to 0 when signal lost, and motor stops. Motor will resume to the current power when the signal is detected again.
• E3. Over-heat Protection: when the temperature increases to above 100 Celsius degree, power will be lowered gradually to less than 75% of the full power. When the temperature increases to above 105 Celsius degree, power will be lowered gradually to less than 50% of the full power. When the temperature increases to above 110 Celsius degree, power will be lowered gradually to less than 25% of the full power. When the temperature increases to above 115 Celsius degree, power will be lowered to less than 6.25% of the full power, and will resume when the temperature decreases.

Programming via Program Card

1. Pull the PPM signal wire out from the receiver, and plug it into the program card jack. Please pay attention to the direction.
2. Connect the ESC to the battery, after 2 seconds you will hear “♪ 2 3 1” tune.
3. The program card automatically reads parameters from the ESC and the corresponding LED will be on.
4. Button 1 is for choosing program items. Button 2 is for choosing different parameters for each item. Button 3 is “write” button. All parameters can be viewed and modified by pressing corresponding and press button 3 to write the new parameters to the ESC.
5. Cut off the power.

Programming via Transmitter

Step 1: Enter program mode

Switch the transmitter on—Pull the throttle stick to the top position—Switch the ESC on, wait 2 seconds, you will hear two “beep” sounds, which denotes that Max. throttle has been confirmed—Hold the throttle stick at the top position, and then wait 2 seconds until you hear tune “♪ 1 2 3 ♪ 1 2 3”, that means you have entered transmitter programming mode.

Step 2: Select program parameters

Hold the throttle stick on top position, there’re 7 parameters can be set by using your transmitter. You would hear 7 different indicating sounds which correspond to 7 different parameters. Pull the throttle stick to the bottom position (full Off throttle) within 2 seconds after you hear the sound will bring you to the corresponding parameter setting status. The indicating sounds will repeat in turn as follow.

1. “beep-” (a short sound) which indicates the Brake Type
2. “beep-beep-” (two short sounds) which indicates the Timing Mode
3. “beep-beep-beep-” (three short sounds) which indicates the Start Force
4. “beep-beep-beep-beep-” (four short sounds) which indicates the Curve Mode
5. “beep-----” (a long sound) which indicates the Control Frequency
6. “beep-----beep-” (a long sound and a short) which indicates the Low-voltage Protection
7. “beep-----beep-beep-” (a long sound and two short) which indicates the Cutoff Mode

Step 3: Select program values

After entering parameter setting status, hold the throttle stick on the bottom position, you will be led to the repeat selection of that parameter setting status. Each sound likes 4 short sounds and one long sound, and that analogy. After some sound, pull the throttle stick to the top position in 2 seconds, after you hear a tune “♪ 3 2 1 3 2 1”, which means the correspondent value has been chosen and saved. Hold the stick on the top position, return to the second step and continue programming.

Step 4: Exit program

Pull the throttle stick to the bottom position within 2 seconds and hold of asaving till you hear a tune “beep----- beep- beep- beep- beep- 1 2 3”. The Min. Throttle at this moment and exit program and operate as normal. (beep----- means Loading parameter. beep- beep- beep- beep- means numbers 1 2 3; the Min. Throttle means ready.)

Applications

• Multicopter / multirotor motor control where a 20A programmable ESC is required
