OUTPUT PORT FOR RPM SIGNALS

Platinum V3 series speed controllers have independent output ports / interfaces for RPM signals, so it can connect to ﬂybarless systems like Mikado V-Bar as RPM signal source. Undoubtedly, this reduces peripheral devices which need to be connected to the ﬂybarless helicopter and simpliﬁes the wiring.

OUTPUT THE REAL-TIME RUNNING STATUS DATA OF THE ESC

Platinum V3 series speed controllers have independent ports for parameter setting, which can also be the output ports of the running status data of the ESCs. When coordinating with the data transmission module, it can make the real-time data monitoring and logging possible.

*Oﬀ / Soft / Hard / Very hard

2, Battery Type: 3, Cuto Mode: 4, Low-voltage Cuto Threshold:

*LiPo / NiMH *Soft cut / Hard cut. Soft means gradually reduce the output power. Hard means cut oﬀ the output immediately.

Oﬀ / Low / *Middle / High / Customized: 2.8V~25.2V，Step: 0.1V

When set as “LiPo battery”, the ESC will automatically calculate the cutoﬀ threshold of the battery pack according to the amount of LiPo cells. The low / middle / high cutoﬀ voltage per cell is 2.85V / 3.15V /

3.30V. For example, when using a 3S LiPo, if set the cutoﬀ voltage as “middle”, the cutoﬀ threshold of this battery pack should be 3.15×3=9.45V.

When set as “NiMH battery”, then the low / middle / high cutoﬀ voltage is 50% / 62.5% / 75% of the initial input voltage (at boot/starting up) . For example, when using a 6-cell NiMH battery pack,

the voltage at starting up is 1.44×6=8.64V; and if set the cutoﬀ threshold as “low”, the cutoﬀ threshold of this battery pack should be 8.64×50%=4.3V.

When set as “Customized: 2.8V~25.2V”, the cutoﬀ threshold of the battery pack can be precisely set (the precision can reach 0.1V). But you need a LCD program box (optional accessory) or USB cable on

the LCD program box to connect the ESC to a PC, then set relevant parameters via a special program (Hobbywing USB Link Software).

5, Flight Mode: Airplane Fixed Wing / Heli Governor O

1) Airplane Fixed Wing:

The motor starts to spin at 5% throttle, then speeds up quickly and reaches the full speed from standstill in 300µs. In this mode, the ESC will be enforced to set the “Auto Rotation

*Heli Governor (Elf) / Heli Governor Store

Restart Time” to “OFF”.

2) Heli Governor O:

When the motor starts at 5% throttle, the startup is very soft and it takes 11 seconds to reach the full speed from standstill. In this mode, if the transmitter is in NORMAL state, then usually the throttle curve is a slash (the start point is the lowest point / 0% throttle, the end point is the highest point / 100% throttle of the throttle range. And this throttle curve is often used by beginners). As the start point is only 5% of the full throttle, the motor rotates slowly that greatly reduces psychological pressure for beginners, so pilots can select this mode for basic practices like “frog leap”. In this mode, the ESC will automatically set the “Auto Rotation Restart Time” to “Oﬀ”.

3) Heli Governor (Elf) & Heli Governor Store：

The motor only starts at 40% (or above) throttle (in governor mode, the motor won’t start when the throttle value is within 0%-40%); its startup is very soft and needs 11 seconds to reach the full speed from standstill. Besides, it has speed-governing function (works at 40%-100% throttle). As the motor rotates quickly in “governor” mode, so it isn’t suitable for beginner anymore but experienced pilots. In these two modes, the setting about “Auto Rotation Restart Time” comes into eﬀect (please refer to “Auto Rotation Restart Time” for more information).

4) Heli Governor (Elf) & Heli Governor Store

have diﬀerent ways of storing target rev data. In “Governor Store” mode, the data are saved into the FLASH of the microprocessor (and the data won’t disappear

after powered oﬀ); while in “Governor (Elf )” mode, data of the nominal target rev are saved into the RAM of the microprocessor (and the data will disappear after powered oﬀ).

• In “Governor (Elf)” mode, the ESC will automatically start the RPM standardization & regain the target rev data after powered on.

• In “Governor Store” mode, if it needs to re-standardize the target RPM, pilots must modify and save the ﬂight mode as any option except "Heli Govornor Store"ﬁrst (without restarting the ESC at this

moment), then modify and save it as "Heli Govornor Store"; the ESC will enter the RPM standardization and regain the target RPM data after it’s powered on. After the ﬁrst activation of the “speed-governing” function or changed accessories (like motor, battery cells amount, gear and diﬀerent type of main/big rotor blades) on the plane, pilots need to standardize the RPM again next time.

Here we suggest pilots take the “Governor Store” mode as their rst option to avoid standardizing rev every time. a) RPM standardization in “Governor (Elf)” mode:

b) RPM standardization in “Governor Store” mode:

when the throttle value switches to over 40% from 0%, the motor starts in a super soft way and accelerates slowly; it completes RPM standardization in 11 seconds and then enters the “governor” mode. After ﬂight, please move the transmitter throttle stick to the bottom position, the motor stops spinning and the ESC will save the standardized (target) RPM into the FLASH. After changed batteries, the ESC will read the target RPM from the FLASH, so there is no need to standardize the rev again.

c) Example for RPM Standardization: In this example, we take the neutral point (50%) of the throttle stick as reference points for standardizing RPM.

• Set the throttle curve (throttle value at the neutral point=50%) & pitch curve (the pitch at the neutral point is 0) in “NORMAL” mode, and keep the throttle HOLD switch “locked” to ensure safety.

• Connect the fully charged battery to the ESC, let the ESC complete the initialization, then move the transmitter throttle stick to the neutral point (here the throttle value at the neutral point is 50% and the pitch of main rotor blades is 0 degree), and then

“unlock” the throttle HOLD switch; the motor will start from standstill in a super soft way, accelerate slowly and completes the target rev standardization 11 seconds later.

• Trial ﬂight. If the target rev is too low, then raise the throttle curve; if the target rev is too high, and then lower the throttle

The example of throttle curve and pitch curve for RPM standardization

curve. E.g. set the throttle curve in IDLE1 / IDLE2 / IDLE3 mode to 65% / 75% / 85% respectively to experience diﬀerent RPM, and then adjust the value according to the actual situation or preference.

As the battery voltage decreases & the pitch of main rotor blades varies in ﬂight, so we recommend setting the throttle curve between 60%~85% (here we strongly suggest not set the value exceeds 85%) on the transmitter to guarantee the speed -governing eﬀect and suﬃcient compensating room to keep the motor’s constant speed. If still can’t reach that target rev when the throttle value exceeds 85%, please change the motor pinion.

For guaranteeing the speed-governing eﬀect, we strongly recommend setting the PWM frequency as 32 kHz.

6, Autorotation Restart Time:

Oﬀ / 5s / *10s / 15s / 30s / 90s.

This parameter is only used in “Governor (Elf )” and “Governor Store” modes, and works when the throttle value is within 5%~40%. During the period of auto rotating (to land), pilots still have the chance to cancel the operation by interrupting the process and restarting the motor quickly. E.g. when set the parameter to 10 seconds,

enabling the throttle HOLD switch (to activate the throttle protection) in ﬂight, the motor will cut oﬀ the output and let the helicopter land. While, if you want to end this process immediately, then you need to “unlock” the HOLD switch (to exit the throttle protection) and increase the throttle value to over 40%, and the ESC will temporarily switch the acceleration time to 1.5 seconds (that is: it reaches the full speed from standstill in 1.5s) and output power quickly. This action protects the helicopter from crashing caused by the motor’s slow acceleration. However, if “lock” the throttle HOLD switch over 10 seconds, the ESC will still output power slowly at a super soft acceleration rate (that means it will take 11s to reach the full speed from standstill) even if you “unlock” the throttle HOLD switch and increase the throttle value promptly.

Security Warning: For safety, please pay attention to the following points.

• When the landing process ends early and the helicopter gets back to ground before the “autorotation restart time”, it’s prohibited to “unlock” the throttle HOLD switch before disconnecting the battery. Otherwise, the helicopter may rotate and accelerate to a high speed in 1.5s and cause accidents. E.g., if “unlock” the throttle HOLD switch in the “Auto rotation restart time” with the helicopter is still in “IDLE” mode, main rotor blades will spin rapidly and the helicopter may drift and tilt even on the ground.

• If switch the ﬂight mode from “IDLE” to “NORMAL” and move the throttle stick to the bottom position (0% throttle) or “lock” the “Throttle Cut” switch on the transmitter, main rotor blades will not rotate even if you accidentally “unlocked” the throttle HOLD switch.

• In “governor ” mode, if set “Auto Rotation Restar t Time” to “Oﬀ”, the motor will always restart at the super soft acceleration rate (it takes 11 seconds to reach the full speed from standstill). Please attention!

7, Advanced Timing:

0deg / 4deg / 8deg / 12deg / *15deg / 18deg / 22deg / 26deg / 30deg / Customized: 0deg~30deg, step: 1 deg. In general, the low timing works ﬁne for most motors. While as great diﬀerences exist among motors, so please try diﬀerent timing(s) to get the best driving eﬀect. For increasing the speed, you can set the timing higher. After the timing adjustment, we recommend having a trial on the ground ﬁrst, and then ﬂy in the sky.

8, PWM Frequency:

8KHz / 16KHz / 24KHz / *32KHz

The rise of PWM frequency can make the motor driving smoother and the noise lower; certainly, this will bring more switching loss for the MOSFET & more heat to the ESC.

9, BEC Voltage:

*5.2V / 6.0V / 7.4V / 8.4V For Platinum-50A-V3 ESCs, the BEC output voltage is selectable among 5.2V / 6.0V / 7.4V; and the actual output will be 7.4V even if you selected 8.4V as the nominal output. For Platinum-100A-V3 ESCs, the BEC output voltage is selectable among 6.0V / 7.4V / 8.4V; but the actual output will be 6.0V even if you selected 5.2V as the nominal output.

10, LiPo Cells:

*Auto calculation / 1 cell / 2 cells / 3 cells / 4 cells / 5 cells / 6 cells The parameter is valid only when the battery pack is LiPo. After powered on, the ESC will make the motor beep the amount of cells in your LiPo pack according to auto-detection or cell count manually set. For Platinum 50A/100A V3 ESCs, the range which can be auto-calculated or manually set is 2~6S; if exceeds, the ESC will warn.

BEGIN TO USE A NEW BRUSHLESS ESC

Before using a new ESC, you need to check all the connections to make sure they are correct and reliable before connecting the ESC to the battery. When ensured everything is ok, then start the ESC in the

sequence:

following 1, Move the throttle stick to the bottom position (throttle value=0%), then turn on the transmitter; 2, Connect the battery pack to the ESC, then the ESC starts self-test; the motor issues “♪ 123” indicating the system is powered on, and N short “beeps” indicating the amount of LiPo cells of the battery pack, then a long “beep—“indicating the self-test is completed successfully and the system is ready to ﬂy.

• If no response is received, please check the battery and battery connections to ensure they are ok and reliable.

• If the motor doesn’t beep after powered on, it means the battery voltage is too low or too high. Please check the battery voltage.

• If the motor sounds “beep-beep-” 2 seconds after powered on, and “♪ 56712 ” 5 seconds later to indicate the ESC is entering the “programming” mode, it means the throttle channel direction in your

. .

transmitter is reversed, in such a case you need to reset the “Normal / Reverse” direction of the throttle channel by referring to the transmitter’s manual.

Attention！

3, To ensure the ESC ﬁts well with the throttle range on your transmitter, you need to reset the throttle range when using this ESC for the ﬁrst time or changed another transmitter for the optimum throttle linearity. For detailed operation, please refer to the explanation in 《Set the Throttle Range》.

EXPLANATIONS FOR WARNING TONE

1. Warning tone for abnormal input voltage

when powered on the ESC, it will start testing the input voltage. If the voltage is not in the normal scope, the motor will emit the warning “beep beep, beep beep,

beep beep” till the voltage returns to normal (the time interval among each group of “beep beep” is 1 second).

2. Warning tone for throttle signal loss

3. Warning tone if the throttle stick is not at the bottom position when the ESC is powered up

when detected no throttle signal, the ESC will issue the following warning: “beep-, beep, beep-” (the time interval among these “beeps” is 2 seconds).

When the throttle is not at the bottom position, the ESC will issue the following warning:

“beep-beep-beep-beep-beep-” (every “beep” is very short and hurried).

EXPLANATION FOR OTHER PROTECTIONS

1. Startup Protection: the ESC will shut down the motor after failed to start the motor normally in 2 seconds by increasing the throttle value, then you need to move the transmitter throttle stick to the bottom position again and restart.

(Causes to this problem

2. Overheat Protection

poor wire connection between the ESC and the motor or disconnection of some output wire, propellers are blocked by other objects, gears are blocked and cannot move and etc.)

When the internal operating temperature exceeds 110 Celsius degree, the ESC will reduce its output power and start protection; it won’t cut oﬀ the output, but reduce it to 50% to

ensure that the motor still has some power for avoiding crash caused by insuﬃcient power. And the ESC will gradually resume its maximum power after the temperature returns to the safe level.

3. Throttle Signal Loss Protection

When detected the signal loss for over 0.25 second, the ESC will cut oﬀ the output immediately to avoid even greater loss which may caused by the continuous high-speed

rotation of propellers or rotor blades.

4. Overload Protection

The ESC will cut oﬀ the power or restart automatically when the load suddenly increases to a very high value. And the common cause of load soar is the lockout of propellers.

NORMAL START-UP PROCESS

Turn on the transmitter and move the throttle stick to the bottom position (Throttle value=0%).

Connect battery to the ESC, the motor will emit “♪123” indicating the ESC is powered on normally.

Then motor emits several short “beeps” to indicate the amount of LiPo cells.

And a long “beep” indicating the system is ready and you can ﬂy the helicopter or airplane now.

SET THE THROTTLE RANGE

Attention! It is necessary to reset the throttle range when using a new ESC or changed another transmitter.

Turn on the transmitter, and move the throttle stick to the top position (full throttle).

Connect battery to the ESC, and the motor emits “♪123” indicating the ESC is powered on normally.

2 seconds later, the motor emits 2 short “beep-beep-” indicating the top position is calibrated successfully.

Move the throttle stick to the bottom position, await 1 second then the bottom position is calibrated Successfully.

The motor emits N beeps to indicate the amount of Lipo cells.

Then a long “beep” indicates the system is ready and you can ﬂy the aircraft now.

DEVELOPER’S GUIDE

【Output the real-time running data of the ESC】

The PLATINUM V3 series of ESC has independent port for connecting the LCD program box and output the running status data of the ESC via the SCI (Serial Communication interface). When coordinating with the data transmission module, they can make the real-time data monitoring and logging possible. Here, we open this functionality to the public so users can redevelop this ESC to expand its application ﬁelds. When motor rotates, the parameter setting port works as single-way mode SCI (Serial Communication Interface), the baud rate is 19200bps. The port outputs 1 data package (/frame) every 20 milliseconds. The format of each data frame is shown as below:

• Package Head: Each data package ( / frame) is always started with the code “0x9B”.

• Package Number: number of each data package.

• Rx Throttle Value: throttle signal value got from the receiver. Now, the “high octet of the Rx throttle value” is temporarily set at 0, and the valid scope of the low octet of Rx Throttle Value is 0~255, that means the entire

throttle range (0~100%) is equally divided into 255 parts. For example, when the low octet value is 85, it means the throttle signal got from the receiver is 33% of the maximum; when it’s 128, the throttle signal received from the receiver is 50% of the maximum.

• Actual Output PWM: throttle signal value actually output by the ESC. Its high octet is also temporarily set at 0, and the valid range of the low octet is 0~255, that means the entire output range (0~100%) is equally divided into 255 parts.

• Actual RPM Cycle: actual electric RPM signal cycle of the motor (µs). For example: The actual rev of a 8-pole motor is 600 RPM, then its electric rev is 600 x 8 ÷ 2 = 2400RPM, which means the ESC commutates 2400 times in 60 seconds to drive the motor, and the commutation cycle = 60 ÷ 2400 = 0.025s = 25000µs. Therefore, the decimal digit represented by the actual RPM Cycle is 25000.

【Output Port for RPM Signals】

• Platinum V3 series of speed controllers have independent output ports for RPM signals.

Specication for interface signals:

•

• It represents the electric rev of the brushless motor (electric rev means the rev of a 2-pole brushless motor). And here is the formula used for converting the actual rev of multi-pole brushless motor into the

electric rev of 2-pole brushless motor: Electric rev = Actual rev of the multi-pole brushless motor × Pole number ÷2 E.g. the actual rev of a 12-pole motor is 5000rpm, so its corresponding electric rev is: 5000 × 12 ÷ 2 = 30000rpm

【ESC throttle Rang & Throttle Signal Specication】

• Factory default of the ESC throttle range is 1100 ~1940µs, the acceptable minimum time of high level is 815µs and the acceptable maximum time of high level is 2256µs. The acceptable minimum signal cycle equals to the high level time (µs) plus 10µs.

• In PPM throttle signals, only signal cycle & high level time impact; changes of the high level time correspond to the notion of throttle value (0%~100%), here whether the low level time changes or not is not taken into consideration.

• Diﬀerent manufacturers have varied deﬁnitions of the high level time of throttle signal. For FUTABA radio system, it is 1100µs~1940µs and 1520µs is the midpoint (or so called “neutral point”); while for JR radio system,

it’s 1100µs~1900µs and the midpoint is 1500µs.

• The receiver outputs analog signals, and the ESC converts the analog signals into 8 to 12bits digital signals (the resolution for 8 bits is 0~255, and it is 0~4095 for 12 bits.).

• Because of the above diﬀerences exist among diﬀerent radio systems; so it’s necessary to calibrate the throttle range on the ESC if users want to utilize the whole throttle range of the transmitter.

It is the periodic signal with duty ratio of 17%, and 0V for low level, 3.3V for high level.
