• When connecting the motor and battery to the
ESC, it is very important to keep enough
safety distance from all moving parts of the
device (such as rotors or propellers). Misuse
or electronic defects may result in an
unintended motor start. A prematurely starting
motor, with connected devices such as rotors
or propellers, may cause considerable
injuries.
Only use the ESC when property and
personal belongings are out of harm's way.
To prevent damage of the ESC, or other
components, always use the designated
mounting brackets.
• The ESC must not be disconnected from the
battery during operation.
• Electrostatic discharge may damage the ESC.
Ensure adequate grounding if necessary.
• Do not use a mechanically or electronically
damaged ESCs as this may result in sudden
failure.
• The ESC may only be operated on batteries.
The use of a power supply is not permitted.
• The ESC is not to be connected in any way to
a 230V AC socket.
• When using high capacity batteries always
ensure sufficient cooling.
• Extending the battery or motor cables can
affect the EMC characteristics. Any extension
of the cables is at your own risk.
• Only
use
a
volt-meter
for
current
measurements. Inserted-meter or shunt can
damage the ESC.
• When using the BEC (to receive the ESC-
power from the main-battery) always connect a
fully charged receiver battery with enough
capacity (also see chap. 4.3). Malfunctions,
e.g. by a cable break, short circuit, slack joint
or failure of a BEC-component, will lead to a
loss of the entire receiver system.
• The system has to be tested on ground before
the first flight, to ensure that the BEC capacity
is sufficient for this application.
3. Basics
All KOSMIK ESCs are equipped with mode
programming. In Mode programming, all individual
parameters
are
set
during
initial
stick
programming. Complex programming of individual
parameters is not necessary for
normal
applications. For additional adjusting of individual
parameters, use a programming unit.
3.1 Throttle curve to prepare the transmitter
for ESC-programming
Please set a linear throttle curve from 0% to 100%
for the throttle channel in your transmitter. The
throttle channel may be set, as desired, to a stick,
switch, slide or knob.
3.2 Programming the ESC with your required
Mode
When programming the requested mode, the ESC
learns the available throttle travel from the
transmitter (0 - 100%). All other necessary
parameters for the selected mode the ESC sets
automatically. For a full description of Mode
Programming, please refer to Section 7 in this
manual. the ESC you need to perform different
steps. Please find the necessary procedure for the
required mode in the relevant section of this
manual.
Please note that mode 1 to 6 cannot be
programmed
via
the
KONTRONIK
programming unit. To avoid a malfunction of
the ESC it is essential to manage the
programming of these modes via the
ESC’s
button
(stick
programming)
and
the
transmitter
(therefore
see
chap.
7,
programming)
3.3 Soft start
When using the soft start function, the ESC
increases the RPM within a selectable time
(slowly increasing).
The time for spool-up from 0% to 100% is freely
selectable via programming unit from 8 to 60 s
(default: 12 s). Maximum head speed is
determined by the straight-line throttle percentage
in your transmitter. Multiple head speeds are
available by using flight modes in your transmitter.
KONTRONIK recommends a value of 80% throttle
for optimum governor control in the transmitter
(this is equivalent to 100% full throttle).
This ensures that the controller has enough
reserve to compensate for the decreasing battery
voltage.
3.4 Low voltage protection
The KOSMIK ESCs are equipped with a deep-
discharge protection, which automatically adjusts
all necessary parameters, regardless of cell count
used. Depending on the mode in use, the motor
rpm will be reduced or shut off when the adjusted
battery discharge voltage is reached.The time for
shut off/slowdown in heli mode is fixed at approx.
30 s.
The low voltage protection is adjustable via
programming unit from 2.7 to 3.5 V (LiPo, default:
3 V), 1.8 to 2.6 V (LiFePo, default: 2.3 V) and 0.7
to 1.2 V (NiCd/NiMH, default 0.8 V) in 0.1 V steps.
