-Programming with the ProgCard II

Initial setup:

After connecting the battery you hear 3 descending tones.
Subsequently, follows a number of beeps according to the
cell number of the connected Lipo battery. In case the
transmitter stick is in throttle off, you hear now 3
ascending tones.
You need to connect the motor to hear the beeps, as it is
the motor itself which acts as a speaker.

--The YGE is ready for use. --


If the motor turns in the wrong direction, exchange simply
2 of the 3 motor wires.

The entire wire length, from the controller to the battery,
may not exceed 15cm. If longer wires are necessary, a
Low ESR switching capacitor of 330μF/25V should be
soldered between plus and minus wires every 20cm.
likewise the motor wires can be extended. Then please
twist the 3 lines, in order to minimize interference
emission.

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
(±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 so that 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 off, and the under voltage recognition adjusted
to Lipo mode 3.0 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 per cell. If there is still no
improvement, then the battery is discharged or too weak,
the wires are too long or to small or a connector is out of
order.
With an active brake you can hear these warning tones
only in windmill position. 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.

Innrunner 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 ProgCard 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 under www.yge.de in the
Download area.


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%). This throttle curve will then correspond to
the controller throttle from 0 to 100%. Please refer also to
ProgCard or RC-Setup manual.

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
-P-Gain = 0,9
-I-Gain = 0,05
-Startup Speed = Heli middle
-PWM-Frequency = 8 kHz )
-Startup Power = Auto 1-32%

You should modify these parameters, only if you don’t get
the desired success, and if you are sure off all other
components. Here except Startup power, are to be
selected mainly 8 or 16%.
On account of the raised load BEC for a 2s Lipo setup is
to be preferred, because heat up with 3s Lipo is to high.

Lipo protection / under-voltage protection:

Because of the tension driven load adjustment it is
possible to fly further with low power, since the battery
recovers with smaller load. However, if the tension
continues to break in, the motor is switched off.

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 in
the interval). But the motor is not switched off in flight
unless the temperature becomes extremely critical, then
the motor switched off.

The partial load operation between half and nearly full
power is the most difficult area for an ESC. 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.

You achieve a better cooling not only through sufficiently
dimensioned air intake, but even more efficiently through
a larger air outtake, in order to avoid a heat accumulation.

You achieve smaller currents by using a smaller propeller
or a one cell smaller battery.

BEC:

If you want to use an additional receiver battery, the red
wire of the BEC connector needs to be disconnected.

If you want to use a buffer battery insert a 1A schottky
diode on the red wire with the cathode going to the
receiver. The buffer battery avoids tension drops on hard
servo maneuvers, protecting the receiver’s functionality.
Two or more ESCs can be connected to a single receiver
if each BEC is fitted with a diode as described above.
A configuration without BEC and with galvanic separation
is also possible. For that please use our opto coupler
module.

Caution:

Fundamentally it is important to make sure that no objects
are within the propeller circle when batteries are
connected. The use of this speed controller is therefore
allowed only in situations where damages and personal
injuries are impossible. A damaged governor (e.g. broken,
damaged by polarity inversion or humidity) must not be
reused under any circumstances. Otherwise it can come
to a later malfunctions or failures.
The ESC may only be powered from batteries, a use from
power supplies is not allowed.

Trouble shooting:

2 Beeps/flashes: Under-voltage identification
3 Beeps/flashes: Temperature rise warning
5 Beeps/flashes: Receiver signals failed
6 Beeps/flashes: start up failed

The ESC signals any error that happened during flight
acoustically (motor) and optically with a blinking LED
code.
Errors 2 and 3 are signaled after motor stop, but aren’t
stored as long as the ESC didn’t cut off completely (low
voltage / temperature warning). In case the error led to a
complete cut off, then it is not cleared by a tension
RESET. The deletion can take place only on purpose by
connecting the battery with the stick at full power and/or
with 100% throttle pre-selection (throttle curve), and
disconnecting it again after the interval beep. Please you
leave the stick at full power, while disconnecting,
otherwise you activate the RC-Setup.
Likewise the errors can be cleared by activating the
ProgCard.
With an activated brake, the error is only signaled after a
tension reset or in wind milling position.

Warranty:

We give 6 months warranty on this speed regulator. Any
other requirements are excluded. That applies in
particular to requirements for damage or injuries
compensation due to malfunction or failure. For damages
to property or personal injuries and their consequences,
which developed from our supply or craftsmanship, we do
not take any liability, since we have no control on handling
and use.
