Initial setup:
Connect the Motor to the ESC to hear the beeps. After connecting the battery (red = plus, black = minus) you hear 3 descending tones. Subsequently, follows a number of beeps according to the cell number of the connected Lipo battery (two rapid beeps for 2s, three beeps for 3s…and s on…6s). When connecting with 7-14s, you will hear two high pitch beeps and two low pitch beeps; after that the ESC is ready for working when you hear 3 ascending tones.
If the motor turns in the wrong direction, simply exchange 2 of the 3 motor wires.
Use only clean and tight gold connectors for motor and battery. The 5.5mm / 6mm PK connectors have proven to be the best choice. Pay attention for the battery connector to choose a polarity safe system. Exchange low-friction or oxidized plugs and sockets. Because only tight sitting contacts will ensure a high current flow, protect the speed controller against dangerous voltage peaks and avoid disturbances.
The entire wire length, from the controller to the battery, may not exceed 20cm. If longer wires are necessary, a Low ESR switching capacitor of high frequency with low internal resistance should be soldered between plus and minus wires every 20cm. Then please twist the 3 lines, in order to minimize interference emission from the transmitter.
Note: Inverting the Battery polarity leads to heavy damage and to the loss of warranty!!!
General settings:
The speed controller has a fixed throttle curve setting, so that with all usual transmitters the stop and full power points are linearly connected. With all programmable transmitters, the throttle range should be set to default setting (±100%), the center point set to zero and throttle trim enabled. Nevertheless, with some transmitter types the range needs to be adjusted. For that the throttle endpoints have to be set two notches: one notch before lowest stick position the motor is stopped and that one notch before full power the motor is actually at full power. Full power is indicated by the LED that is completely turned off.
On delivery the Timing is adjusted to 18°, brake is switched on middle, and the under voltage recognition adjusted to Lipo mode 3.1 V. If during spin up rpm variations (wowing or erratic sound) are experienced, the timing must be increased. If no improvement can be obtained at 30°, then the motor is overloaded. Here a smaller propeller, a one cell smaller battery or a stronger motor will help. If after motor stop you hear 2 beeps repeating, it means that the battery voltage dropped down below the setting value. Eventually try a cutoff voltage of 2.9V/3.0V per cell. If there is still no improvement, then the battery is discharged or too weak, the wires are too long or too small or a connector is out of order.
This is the small range on the throttle stick between brake and motor start. You can reach this position with 2 notches or with a high trim and a short gas start.
If no automatic timing is wished, it can be adjusted according to the following guideline.
Inrunner 0° to 12°
Outrunner 18° to 30°
If your motor manufacturer indicates a timing recommendation, it is of course preferable to use it. Basic rule: the higher the timing the higher the full power rpm.
The easiest to make these changes is the Prog Card II. There is also the possibility to perform the setup with the transmitter; however it will not be explained here. You will find it in the RC-setup manual.
In case you get inadvertently in the programming mode during a normal start-up (throttle stick at full power), simply disconnect the battery, lower the stick to stop, and connect the battery again. Thus you won’t modify the adjustments.
Helicopter settings:
For helicopters in governor mode, the full throttle range (100%) must be calibrated once. For some transmitters, this range is indicated in the helicopter menu (throttle curve 0--100%) and some other transmitters -100...+100. Please refer the RC-Setup especially the Basic Setup or Prog-Card.
When activating one of the governor modes, all relevant heli parameters are set to default. This default will fit nearly all setups. You don’t need to program further at a first step.
Here a listing of the default settings.
- Timing = 18°
- Brake off
- Act. Freew. on
- P-Gain = 0,9
- I-Gain = 0,05
- Startup Speed = Heli middle
- PWM-Frequency = 8 kHz )
- Startup Power = Auto 1-32%
- Under voltage protection = Soft cutoff
You should modify these parameters, only if you don’t get the desired success, and if you are sure off all other components.
Active free-wheel:
The ESC can keep cooled obviously, heating reduced.
Temperature / overload warning:
If the speed controller’s temperature exceeds its limit, because of overloading or lack of cooling, after landing and/or motor stop, a warning signal is issued (3 Beeps inthe interval). But the motor is not switched off in flight unless the temperature becomes extremely critical, then the motor switched off.
In addition the running time becomes longer and longer with the Lipo technology. If it should come to repeated temperature warnings, better cooling should be provided or current should be reduced. These warnings are to be regarded as overload warnings and not as normal operating condition. Because at high temperature the components are strongly stressed, this leads to a decreased life time.
==============================================================
ALL FUNCTION on ESC Ice-Series
Level 1 (Page#1)
Shortly after that the current settings are read from the ESC as long as it is a BEC model. All LED will light up in a row. (Optocoupler ESC’s from V4 push Enter button now.) You are now on level 1, starting with the timing indicator. Now you choose with the lower left button the Menu selection and can see the programmed setting on the LED line. With the upper left button you can now choose a new value that will be actually programmed into the ESC with the Enter button on the right. The ESC will acknowledge with a positive beep. (The LED on the ProgCard II will turn on shortly and is followed by a low and a high tone beep.)
Functions that cannot be programmed in the ESC are signaled with a negative beep. (1 low tone) All function can be adjusted like that, while the programming order is not relevant except for the Lipo type followed by the cutoff voltage adjustment and the cell count. Though, you can modify later on any single value anytime. 2 and 3 cells are recognized automatically by the controller.
That is why the cell count settings are starting with 4 cells on the ProgCard II.
The programming of the cell count is saved in the controller. Connecting a different cell count battery would lead to wrong under voltage detections.
Reset the Lipo type (LiPo / LiFe) will cancel the cell count and set the ESC again in automatic cell count detection!
By activating the LiFe cell type (LiFePO4), the cutoff voltage is reduced by 0.7V per cell.
Cutoff voltage (upper cutoff voltage line) for LiFe is 2.2 to 2.7V per cell.
Cutoff voltage (lower cutoff voltage line) for LiPo is 2.9 to 3.4V per cell.
In the NiMh mode, neither the cutoff voltage nor the cell count needs to be programmed. The slowdown is done automatically based on the battery voltage during connection. (Therefore, use only fully charged NiMh batteries)
Beep short shortens the start beep.
Rev. (Navy) Forward and reverse activation (only for Navy ESC).
Stick position Brake off (without brake)
For the throttle stick range calibration, please connect the enclosed extension cable from the receiver to the rightmost connector of the ProgCard II.
Turn on the transmitter, and put the throttle stick to low-position. Select function STOP LED is on the ProgCard II and push the Enter button. Next move joy stick to high power position and select function Full Speed LED in on the ProgCard II and push the Enter button.
Stick position Brake on (with brake)
The brake starts 10% below the stop position, so the throttle stick range needs to be calibrated a bit shorter. For that put the throttle stick on 10% power ( about 3 notches away from stop) and proceed with the above calibration. Alternatively you can also learn in the complete stick range, after having set the servo travel from 10% to 100%.After calibration you need to come back to 0% - 100% to be able to reach the brake position.
For transmitters with -100 to +100% servo travels you need to program -80% to +100% for calibration and come back to -100, +100% after calibration.
Brake smooth, middle, hard These three steps are only for folding air-screw!
F3A Brake
This function allows to adjust the F3A brake intensity without any step. It can reduce the motor RPM while the plane fly downward. You need again the extension cable, like described above, select theF3A Brake LED, position the stick, e.g. for 50% brake on half throttle, and press the enter key. Likewise for 75%, put the stick on 3/4 gas, etc.
For the throttle stick range calibration, lower servo travel of the throttle channel needs to be increased by 10% because the opto-coupler has a propagation delay of 50¦Ìs and thus the stop point is shifted.
Level 2 (Page#2)
All other functions like the governor mode can be accessed through the level 2 of the ProgCard by pushing briefly the two left buttons simultaneously. For confirmation the menu LED is blinking now. By pushing again the two left button you come back to level 1 exactly where you left level 1.
Act. Freewheel (active Freewheel) allows best efficiency in the partial load range whereby the ESC remains clearly cooler
Governor Mode (Gov. / Gov. Store)
For the use of the governor mode in a helicopter, the throttle stick range or the throttle curve (100%) must have been calibrated as described in level 1.
A throttle curve point of e.g. 70% corresponds to a completely determined head speed, which is held as long as possible for the ESC due to the battery voltage. If the battery voltage drops below a certain level, even a full power setting won’t be able to reach the demanded head speed if the voltage doesn’t allow it. If this appears to be the case at the end of a flight, the throttle curve should be reduced accordingly.
For both governor modes: don’t modify the P-gain, I-gain and PWM switching rate initially! If you do so the control loop parameters would also be modified.
Governor Mode is the classical head speed regulation for helicopters. The setting of the throttle curve should be around 60 to 80% of the full throttle range.
The controller learns at every start the correspondence of the throttle curve and the head speed. That is why there is a short head speed increase just before reaching the demanded speed. This can disturb the tail, but a slight pitching will settle things down as the helicopter is not“glued” to the ground anymore.
Gov. store is an extended helicopter feature, where the correspondence of the throttle curve and the heads peed is done only at the first start (learning procedure). This head speed is stored so that at every later start the head speed will remain exactly the same.
If the learning wasn’t successful or wrong, you can reset the learning by selecting once again the Gov. Store.
Operating instructions
The setting of the throttle curve should be the full throttle range (eg.80%).
Start the ESC and stop for a while when it reach the highest head speed. A fault RPM will be noticed. Turn off the ESC and disconnect the battery. Reset the throttle curve at the same or lower throttle range when connecting battery next time.
If unsuccessful or fault to learning throttle curve, you could reset by reselecting Gov. Store.
The learning can even be done with nearly or exact 100%. Doing this will improve the correspondence of the throttle curve to the actual head speed. But please be careful as 100% learning could lead to very high head speeds, and anyway don’t forget to set back the throttle curve to avoid flying with full power.
Fast (Gov.) can be selected along with both governor modes. This feature increases the control loop frequency and can be used above a magnetic pole commutation frequency of 80000/min. (pole/2x motor- rpm)
To try only if the speed control is not completely satisfactory.
The advantages are that the P and I gains can be reduced without getting a weak speed control.
Important notice for the governor Fine Tuning.
The governor software default parameters are adapted to most setups. Nevertheless, if necessary the following parameters (P and I gain) can be adjusted.
P-Gain is the proportional gain. According to this parameter, head speed variations will be regulated
harder or softer. Practically, it is the force of the control loop. (- weaker, + stronger). With smaller helis, less then 1m rotor diameter, this parameter shouldn’t exceed 1 meter. With larger diameters you can go to the max. A bad adjustment is reflected by a wagging tail.
I-Gain is the integral gain. According to this parameter, remaining head speed deviations are corrected faster or slower. It is an important complement to the P term: The P control is fast, but cannot recover completely the demanded head speed as it needs this deviation to exist. The I-term remembers this small remaining deviation and is able to remove it completely thanks to its “memory”
Both parameters should be adjusted simultaneously. If you can increase the P-term, you should generally also be able to increase the term and vice versa.
To high settings can lead to a resonance between tail gyro and governor. The result is then a very noisy or even wagging tail that could lead to an out of control situation.
There fore the adjustments on P and I should be done in small steps.
By selecting again one of the governor modes, these parameters are reset to their default values.
Startup Speed is the spool up speed for helicopters and planes.
PWM Frequency is the switching rate used for partial load operation. With low frequencies the losses are reduced, but the motors run slightly rougher. With high frequencies, it is the opposite. The optimum frequency may be found in the user manual of your motor.
Startup Power The higher the startup power, the faster and harder is the start. With small propellers it isn’t a problem, but with large ones, it can lead to a fairly rough startup behavior.
Before you disconnect the ProgCard from the ESC, you can verify your programmed settings by scrolling through each menu line. But this is only a history of your recent settings and doesn’t reflect the other settings of the ESC. For that you have to read it in again.
