- 1 Brushless Speed Controller Manual Modellsport Schweighofer. Brushless Speed Controller Manual Modellsport Schweighofer.

Features:

◆ Compatible with Lithium and Nickel battery types. (Lithium-Ion / Lithium-Polymer or Nickel Metal Hydride / Nickel Cadmium)

◆ Extreme low output resistance, super current endurance.

◆ Multiple protection features: Low-voltage cut-off protection / over-heat protection / throttle signal loss protection.

◆ 3 start modes: Normal / Soft / Super-Soft, compatible with fixed-wing aircraft and helicopter.

◆ Throttle range can be configured to be compatible with all transmitters currently available on market.

◆ Smooth, linear and precise throttle response.

◆ Separate voltage regulator IC for microprocessor (except Pentium-6A and Pentium-10A), providing good anti-jamming capability.

◆ Supported motor speed (Maximum): 210000 RPM (2 poles), 70000 RPM (6 poles), 35000 RPM (12 poles). pack into the BDMP socket on the Guard series ESC, the ESC monitors are not only the voltage of the whole battery pack but also the voltage of each cell). For lithium battery，low / medium / high cut off voltage for each cell is: 2.6V/2.85V/3.1V. When the voltage of any cell in battery pack is lower than the cut-off threshold, the protection function is activated.

Normal is preferred for fixed-wing aircraft. Soft or Super-soft are preferred for helicopters. The initial acceleration of the Soft and

Super-Soft modes are slower in comparison, usually taking 1 second for Soft startup or 2 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is closed (throttle stick moved to bottom) and opened again (throttle stick moved to top) within 3 seconds of the initial startup, the restart-up will be temporarily changed to normal mode to get rid of the chances of a crash caused by slow throttle response. This special design is very suitable for aerobatic flight when quick throttle response is needed.

Note1: BEC means the “Battery Elimination Circuit”. It is a DC-DC voltage regulator to supplies the receiver and other equipments from the main battery pack. With the build-in BEC of an ESC, the receiver needn’t to be supplied with an additional battery pack.

IMPORTANT! The ESC named “xxx-xxx-OPTO” hasn’t a built-in BEC, an UBEC (Ultimate-BEC) or an individual battery pack should

Special Note

Some high KV out-runner motors have very special construction, for the space between each magnet is very large, and many ESCs can’t drive these motors. After much testing, our ESCs have proven to work very well with these types of motors. Some RC enthusiasts still have several questions about the programming value for these special motors. Therefore, we have provided some suggestions as be used to power the receiver. And an individual battery pack is needed to power the program card when setting the programmable value of such ESCs, please read the user manual of program card for reference.

Begin To Use Your New ESC

1. Move the throttle to stick the bottom position and then switch on the transmitter.

2. Connect the battery to pack the ESC, when the ESC begins the self-test process, a special tone “♪123” is emitted, which means the voltage of the battery pack is in normal range, and then N “beep” tones will be emitted, which means the number of lithium battery cells. Finally a long “beep------” tone will be emitted, which means self-test is OK, the aircraft/helicopter is ready to go flying.

◆ If nothing is happened, please check the battery pack and all the connections;

◆ If a special tone “♪56712” is emitted after 2 beep tones (“beep-beep-”), which means the ESC has entered the program mode, it is because the throttle channel of your transmitter is reversed, please set it correctly;

◆ If the very rapid “beep-beep-, beep-beep-” tones is emitted, which means the input voltage is too low or too high, please check your battery’s voltage.

3.

“VERY IMPORTANT !”

Because different transmitters have different throttle range, we strongly suggest you use the “Throttle

Range Setting Function”to calibrate throttle range.

◆ When NOT using balance discharge monitoring and protection function (i.e. Not plugging the balance charge connector into the BDMP socket on the Guard series ESC, the ESC only monitors the voltage of the whole battery pack )

1) For lithium batteries, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.6V/2.85V/3.1V. For example: For 3 cells lithium pack, when “Medium” cutoff threshold is set, the cut-off voltage will be: 2.85*3=8.55V.

2) For nickel batteries, low / medium / high cutoff voltages are 0%/45%/60% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 10 cells NiMH battery, fully charged voltage is 1.44*10=14.4V, when “Medium” cut-off threshold is set, the cut-off voltage will be:14.4*45%=6.5V。

◆ When using balance discharge monitoring and protection function (i.e. Plugging the balance charge connector on battery

Alert Tone

1. Input voltage is abnormal: The ESC begins to check the voltage when the battery pack is connected, if the voltage is not in the acceptable range, such an alert tone will be emitted: “beep-beep-, beep-beep-,beep-beep-” (Every “beep-beep-” has a time interval of about 1 second. )

2. Throttle signal is abnormal: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “beep-, beep-, beep-”. (Every “beep-” has a time interval of about 2 seconds)

3. Throttle stick is not in the bottom position: When the throttle stick is not in bottom (lowest) position, a very rapid alert tone will be

Protection Function

1. Abnormal start up protection: If the motor fails to start within 2 seconds of throttle application, the ESC will cut-off the output power. In this case, the throttle stick MUST be moved to the bottom again to restart the motor. (Such a situation happens in the following cases:

The connection between ESC and motor is not reliable, the propeller or the motor is blocked, the gearbox is damaged, etc.)

2. Over-heat protection: When the temperature of the ESC is over 110 Celsius degrees, the ESC will reduce the output power.

3. Throttle signal loss protection: The ESC will reduce the output power if throttle signal is lost for 1 second, further loss for 2 seconds will cause its output to be cut-off completely.

Program Example

Setting “Start Mode” to “Super-Soft”, i.e. value #3 in the programmable item #5

1. Enter Program Mode

Switch on transmitter, move throttle stick to top position, connect battery pack to ESC, wait for 2 seconds, “beep-beep” tone should be emitted. Then wait for another 5 seconds, special tone like “♪56712” should be emitted

2. Select Programmable Items

Now you’ll hear 8 tones in a loop. When a long “beep------” tone is emitted, move throttle stick to bottom to enter the “Start

Mode”

3. Set Item Value (Programmable Value)

“Beep-”, wait for 3 seconds; “Beep-beep-”, wait for another 3 seconds; then you’ll hear “beep-beep-beep”, move throttle stick to top position, then a special tone “♪i5i5” is emitted, now you have set the “Start Mode” item to the value of “Super-Soft”

4. Exit Program Mode

After the special tone“♪i5i5“, move throttle stick to bottom within 2 seconds.

Trouble Shooting

Trouble Possible Reason

After power on, motor does not work, no sound is emitted

After power on, motor does not work, such an alert tone is emitted:

“beep-beep-,beep- beep-,beep-beep-” (Each “beep-beep-” has the time interval ofabout 1 second)

After power on, motor does not work, such an alert tone is emitted: “beep-, beep-, beep- ”(Each “beep-” has the time interval of about 2 seconds)

After power on, motor does not work, such an alert tone is emitted: “beep-, beep-, beep-” (Every “beep-” has the time interval of about 0.25 second)

The connection is not correct between battery pack and ESC

Input voltage is abnormal, too high or too low.

The connector of Balance charger is not located properly in BDMP adapter.

Throttle signal is irregular

The throttle stick is not at the bottom (lowest) position

After power on, motor does not work, a special tone “♪56712 “ is emitted after twice (beep-beep-)

Direction of the throttle channel is reversed, so the ESC has been entered the program mode

The motor runs in the opposite direction The connection needs to be changed between ESC and themotor.

The motor stop running while in working state

Throttle signal is lost

ESC has entered Low Voltage

Protection mode

Some connections are not reliable

4. Exit program mode

1. Enter program mode

1) Switch on transmitter, move throttle stick to top , connect the battery pack to ESC

2) Wait for 2 seconds, the motor should emit special tone like “beep-beep-”

3) Wait for another 5 seconds, special tone like “56712“ should be emitted, which means program mode is entered

2. Select programmable items:

After entering program mode, you will hear 8 tones in a loop with the following sequence. If you move the throttle stick to bottom within 3 seconds after one kind of tones, this item will be selected.

1. “beep“ brake (1 short tone)

2. “beep-beep-“ battery type (2 short tone)

3. “beep-beep-beep-“ cutoff mode (3 short tone)

4. “beep-beep-beep-beep-“ cutoff threshold (4 short tone)

5. “beep-----“ startup mode (1 long tone)

6. “beep-----beep-“ timing (1 long 1 short)

7. “beep-----beep-beep-“ set all to default (1 long 2 short)

8. “beep-----beep-----“ exi t (2 long tone)

Note: 1 long “beep-----“ = 5 short “beep-“

3. Set item value (Programmable value):

You will hear several tones in loop. Set the value matching to a tone by moving throttle stick to top when you hear the tone, then a special tone “♪i5i5“ emits, means the value is setted and saved. (Keeping the throttle stick at top, you will go back to step 2 and you can select other items; Moving the stick to bottom within 2 seconds will exit program mode directly)
