b) Programming the Special Functions
All special functions of the speed controller can be programmed very simply and comfortably via the enc-
losed programing card.
Proceed as follows for programming:
• Placethemodelvehiclesothatthewheelscanturnfreely.Useasuitablebasisoracarstand.
• Takethetransmitterintooperation;insert,e.g.,batteries/rechargeablebatteriesandswitchonthetrans-
mitter.
 Leavethethrottle/brakeleverinitsneutralposition(donotmovethelever).Putthetrimmingfordrivinginto
the centre position.
• Connectafullychargeddrivebatterytothespeedcontrollerifyouhavenotdonesoalreadyorswitchoff
the speed controller.
• Connecttheprogramingcard(3)tothecorrespondingsocket(8)atthespeedcontrollerviatheenclosed
connectioncable(4).
 Alwaysensurecorrectpolarity.Acolourmarkorlabel„+“,„-“and„S“helpsmaketheproperconnection.
• Switchonthespeedcontrollerbybrieypushingtheoperatingbutton(9).Thentheprogrammingcard
shows the current programming by its LEDs.
• Brieypushingthebuttonontheprogramingcard(lowerright)permitsswitchingbetweenthedifferent
functions.Foradescriptionofthefunctions,seethenextchapter.
To change the current value, keep the button on the programming card pushed for a longer time. The LEDs
showtherespectivevalue;releasethebuttonagainwhenthedesiredvaluehasbeenset.TheLEDinthe
speedcontrollerthanbrieyashesgreen.
• Ifyouwanttoterminateprogramming,switchoffthespeedcontrollerbykeepingtheoperatingbutton(9)
pushed for one second.
 Thendisconnecttheprogrammingcardfromthespeedcontroller;pulltheconnectioncable(4)fromthe
socket (8) of the speed controller.
Description of the programmed special functions
Note:
When the programming card is connected to the speed controller, the motor is deactivated for
reasons of safety.
„Cut-off Voltage“ Function: Undervoltage protection
IfLiPorechargeablebatteriesareused,thenyoumustensurethatthelow-voltageprotectionisactivatedand
set correctly (we recommend at least 3.0 V per cell). When operating a LiPo battery without undervoltage
protectionorwhensettingtoolowavalue,theLiPobatteryispermanentlydamagedbydeepdischarge!
• „AutoLiPo“(automaticrecognitionofthecellnumber;basicsetting)
 ThespeedcontrollermeasuresthevoltageoftheconnectedLiPodrivebatterywhenswitchingon.Ituses
this voltage to calculate the cell number (e.g. 2 or 3 cells). Depending on the deactivation voltage set in
thefunction„Auto-LiPoCutoffVolts/Cell“,thespeedcontrollerswitchesoffthemotortopreventdeep
discharge of the LiPo rechargeable battery.
When this setting is chosen, connect a fully charged LiPo drive battery, but never a partially charged one.
Otherwise,thecorrectcellnumbercannotberecognisedcorrectly.
• „None“(noundervoltageprotection)
This setting must only be chosen if you operate the speed controller with a NiMH drive battery.
• „5V“,„6V“,„9V“,„12V“(xedvoltagevalue)
 Thesesettingscanbeusedtospecifyaxedvoltagevalueforundervoltageprotection.
 Thesetting„5V“must,however,notbeusedforany2-or3-cellLiPodrivebattery!
Function „Auto-LiPo Cut off Volts/Cell“: Cell voltage for undervoltage protection
Ifthesetting„AutoLiPo“ischoseninthefunction„CutOffVoltage“,youmustsetthecellvoltageherewhen
the speed controller is to switch off the motor.
The speed controller measures the voltage of the connected LiPo drive battery when switching on (this must
befullyloaded).Itusesthisvoltagetocalculatethecellnumber(e.g.2or3cells).
Ifyouhave,e.g.,connectedatwo-cellLiPodrivebatteryandsetavoltageof3.1V,thespeedcontroller
switchesthemotoroffatatotalvoltageof6.2V(2cellsx3.1V=6.2V).
Avalueof3.0V/cell,3.1V/cell,3.2V/cellor3.3V/cellispossible;thedefaultsettingis3.2V/cell.
Function „Drag Brake“: Motor brake
Ifyoureducethethrottleatthetransmitterormovebackthethrottle/brakeleverintotheneutralposition,
thevehiclewillslowdownautomatically.Theeffectisthusexactlylikethatofthemotor-brakingfunctionina
„real“ car when you release the throttle pedal without stepping on the brake pedal.
This also corresponds to the brake function of a conventional electric motor (a brushless electrical motor
does not have any strong magnets that brake the rotor).
Avaluefrom0%to30%canbesetinstepsof5%;thedefaultsettingis10%.
Function „Brakes Strength“: Brake force
The speed controller unit allows proportional braking strength depending on the setting of the transmitter
lever. A high setting (e.g. 100%) decreases braking distance but has a negative effect on the lifetime of the
drive(specicallyforthedrivepinionandthemaingear).Thebrakeisswitchedoffforthesetvalue„0%“.
Avaluefrom0%to100%canbesetinstepsof10%;thedefaultsettingis80%.
Function „Punch Strength“: Acceleration when starting to drive (start-up torque)
Dependingonthissetting,thetake-off/startspeedismoreorlesspowerful.Thehigherthesetvalue,the
morecurrentwillthemotorpullfromtheconnectedbattery;itmustaccordinglybeofhigherquality.
A higher setting also should only be used on loose underground, since otherwise there may be an overload
of the drive.
Thevaluecanbesetfrom0to30instepsof5;thedefaultsettingis10.
„Dead Band“ Function: Neutral position recognition range
Sethowhightheareaforrecognitionoftheneutralpositionatthetransmitteris.
Ahigherarea(„Large“)mustbesetwhenthemechanicsforthethrottle/brakeleveratthetransmitterworks
inaccurately.Forhigher-valuetransmitters,thesetting„Small“or„Normal“mustbeused.Thedefaultsetting
is „Normal“.
„Reverse Type“ function: Drive function
Inthisfunction,thedrivefunction(forward/reverse)andthebrakecanbeprogrammed.
• „ProportionalRev.LockOut“
 Reversedrivingisonlypossibleifthethrottle/brakeleveratthetransmitterhasbeenintheneutralposition
for2seconds.Otherwise,onlythebrakeisactivatedifyoumovethethrottle/brakeleveratthetransmitter
to the position for reverse driving.
• „Proportionalw/oReverse“(defaultsetting)
 Reversedrivingisdeactivated.Ifthethrottle/brakeleveratthetransmitterismovedtothepositionfor
reverse driving, the drive is only braked.
• „FWDtoBrakeandReverse“
 Bothforwardandreversedrivingorthebrakefunctionareactivated.
 Ifthethrottle/brakeleveratthetransmitterismovedwithoutpausefromforwardtoreversedriving,the
speedcontrolleractivatesthebrakefunction.Ifthethrottle/brakeleverisbrieyintheneutralposition
between forward and reverse driving or if the vehicle is standing, the vehicle will then drive backwards.
„Motor Timing“ Function: Brushless motor timing
Thissettinginuencesmotorrunningcharacteristics(similartoearlyignitionofacombustionengine).
You can change this setting in steps of 5° from „None“ (no timing change, 0°) via „Low“, „Middle“ to
„High“(30°).
Ifyouset„None/0°“,themotorhasalittlemoretorqueandalittlelowermaximumrotatingspeedthanin
thedefaultsetting(10°).Setting„High/30°“meansthatthemotorhasalittlehighermaximumspeedanda
little less torque.
Inbothcases,thecurrentvalueschangehowever.Additionallyobservethetemperaturesofthemotorand
speed controller in operation.
„ESC Type“ function: Speed controller type
This LED shows whether a motor with sensor connection has been recognised (such as the enclosed brush-
less motor with sensor cable).
„Motor Direction“ Function: Rotating direction of the motor
Withthisfunction,youcanswitchtherotatingdirectionofthemotorsothatthemovementatthethrottle/
brake lever of the transmitter matches the driving direction of the vehicle (depending on the gear of the model
vehicle).Thedefaultsettingis„Normal“;„Reverse“reversestherotatingdirection.
