I. Connections

1. Throttle Signal Cable (Long White/Red/Black Tri-color Cable): plug it into the TH channel on the receiver or flight controller. The White wire is for transmitting throttle signals, the Red & Black wires are BEC output wires.
2. Reverse Brake Signal Wire (Yellow Wire): it must be plugged into any vacant channel on the receiver (when using the Reverse Brake mode) to control the ON/OFF of the Reverse Brake function.
3. Programming Cable (Short White/Red/Black Tri-color Cable): connect it to a LED program box if users want to program the ESC.

ESC Programming

There are two ways to program the ESC. One way is to program it with a LED program box; the other way is to program it with the transmitter. The ESC has many programmable items, so we recommend using the LED program box to do the ESC programming.

I. Program your ESC with a LED Program Box
Wiring:

a). Plug the programming cable (on your ESC) into the programming port on the LED program box.
b). (With a battery connected to your ESC), after connected a LED program box to the ESC, you need to disconnect the battery first and then reconnect it to the ESC to enter the programming mode, check and set parameters.
The portable program box is an optional accessory applicable for field use. Its friendly interface makes the ESC programming easy and quick. Connect a battery to your ESC after connecting a LED program box to the ESC, all programmable items will show up a few seconds later. You can select the item you want to program and the setting you want to choose via “ITEM” & “VALUE” buttons on the program box, and then press the “OK” button to save all new settings to your ESC.
Attention! You need to power your ESC off and then on after adjusting parameters. Otherwise, new parameters won’t take effect.

II. Program your ESC with the Transmitter
Wiring:

ESC Programming via the Transmitter (Throttle Stick)
It consists of 4 steps: Enter the programming → Select parameter items Select parameter values → Exit the programming

VI. Exit the Programming
Move the throttle stick to the bottom position within 3 seconds after you hear two long beeps and two short beeps (emitting from the motor) can get you exit the programming mode. The motor beeps “Number” beeps to indicate the number of LiPo cells you have plugged in, and then a long beep to indicate the power system is ready to go.

Programmable Items

1. Brake Type
   Normal Brake
   After selected this option, the brake function will be activated when you move the throttle stick to the bottom position. In this mode, the brake amount equals to the brake force you’ve preset.
   Proportional Brake
   After selected this option, the throttle range of 20% to 100% (on the transmitter) will correspond to the ESC throttle output of 0% to 100% while the throttle range of 20% to 0% (on the transmitter) will correspond to the brake force of 0 to 100%.
   Reverse Brake
   After selected this option, the Reverse Brake signal wire (its signal range must be the same as the throttle range) must to be plugged into any vacant channel on the receiver, and you can control the motor direction via that channel. The channel range of 0-50% is the default motor direction, and the channel range of 50% to 100% will cause the motor to spin counterclockwise. The channel stick should be within the channel range of 0-50% (0 would be better) when the first time you power on the ESC. After the Reverse function is activated, the motor will stop first and then spin in the reversed direction and then increase to the speed corresponding to the throttle input. Either signal loss, no matter reverse brake signal loss or throttle signal loss during the flight, can cause the throttle signal loss protection to be activated. If this function is enabled, the reverse signal cable is not connected to any channel. This function is disabled.
2. Brake Force
   This item is adjustable from level 1 to level 7. The higher the level, the stronger the braking effect. It’s only effect in the “Normal brake” mode.
3. Voltage Cutoff Type
   Soft Cutoff
   After selected this option, the ESC will gradually reduce the output to 50% of the full power in 3 seconds after the low-voltage cutoff protection is activated.
   Hard Cutoff
   After selected this option, the ESC will immediately cut off the output when the low-voltage cutoff protection is activated.
4. LiPo Cells: The ESC will automatically calculate the number of LiPo cells you have plugged in as per the “3.7V/Cell” rule if “Auto Calc.” is selected, or you can set this item manually.
5. Cutoff Voltage
   This item is adjustable from 2.8V to 3.8V (they are the cutoff voltages for one cell), it’s 3.0V by default; or you can disable it if necessary.
6. BEC Voltage
   This item adjusts the switch-mode BEC output voltage, it can be adjustable among 5.2V, 6.0V and 7.4V.
7. Start-up Mode
   Normal Start-up
   After selected this option, the motor will immediately start spinning and then quickly reach to the corresponding speed when you move the throttle stick from bottom position to top position.
   Soft Start-up
   After selected this option, the motor will slowly start spinning and then quickly reach to the corresponding speed when you move the throttle stick from bottom position to top position.
   Very Soft Start-up
   After selected this option, the motor will slowly (slower than in “Soft Start-up Mode”) start spinning and then quickly reach to the corresponding speed when you move the throttle stick from bottom position to top position. We recommend selecting the “Soft Start-up” or “Very Soft Start-up” mode when you’re using a big-sized ducted motor.
8. Timing
   This item is adjustable from 0 degree to 30 degrees, and it is 15 degrees by default.
9. Motor Rotation
   This item allows you to adjust the rotation direction of your motor between CW and CCW, and it is CW by default.
10. Freewheeling (DEO)
    This item is adjustable between “Enabled” and “Disabled”, and it is enabled by default. With it enabled, you can have better throttle linearity or smoother throttle response.

Troubleshooting & Multiple Protections

Troubleshooting

Multiple Protections

1. Start-up Protection:
   The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time, if the throttle amount is less than 15%, the ESC will try to restart automatically; if it is larger than 20%, you need to move the throttle stick back to the bottom position first and then restart the ESC. (Possible causes of this problem: poor connection/disconnection between the ESC and motor wires, propellers are blocked, etc.)
2. ESC Thermal Protection:
   The ESC will gradually reduce the output but won’t cut it off when the ESC temperature goes above 110°C. For ensuring the motor can still get some power and won’t cause crashes, so the maximum reduction is about 50% of the full power. The ESC will gradually resume its maximum power after the temperature lowers down. In addition, the ESC temperature cannot exceed 70°C when it’s powered on. Otherwise, it cannot be started up. (Here we are describing the ESC’s reaction in soft cutoff mode, while if in hard cutoff mode; it will immediately cut off the power.)
3. Throttle Signal Loss Protection:
   When the ESC detects loss of signal for over 0.25 second, it will cut off the output immediately to avoid an even greater loss which may be caused by the continuous high-speed rotation of propellers or rotor blades. The ESC will resume the corresponding output after normal signals are received.
4. Overload Protection:
   The ESC will cut off the power/output or automatically restart itself when the load suddenly increases to a very high value. (Possible cause to sudden load increase is that propellers are blocked.)
5. Over-current Protection:
   The ESC will cut off the power when the current gets close to the short circuit current. This protection may be activated by the burnt motor or some others.
