1. page 1 Manual of Sensorless Brushless Speed Controller The direction of throttle channel is Set the direction of throttle channel correctly reversed so the ESC has entered the program mode HW SM002DUL 20130610 After power on motor cant work a special tone 56 12 emits after 2 beep tones beep beep 2 Select Programmable Items Now you ll hear 9 tones in loop When a long beep tone emits please move the throttle stick to bottom position to enter the Startup Mode item The motor runs in opposite direction The connection between ESC and Swap any two wire connections between ESC and the motor need to be changed motor state Check the cable of throttle channel ESC has entered Low Voltage Land RC model as soon as possible and then Protection mode replace the battery pack Some Connections are not reliable Check all the connections battery pack connection throttle signal cable motor connections etc 2 Select programmable items How To Use The Program After entering program mode you can hear 9 tones in a loop in the Card following sequence If you move the throttle stick to bottom within 3 1 Connect the battery seconds after one kind of tones then this item will be selected 4 8Vto 6V to the port beep Brake 1 short tone marked with BATT 4 Exit Program Mode _ After the special tone 1515 move the throttle stick to bottom position within 2 seconds 2 Connect th2. Li xx Li ion or Li po Ni xx NiMh or Nicd default is Li xx 3 Low Voltage Protection Mode Cutoff Mode Soft Cutoff Gradually reduces the output power or Hard Cutoff Immediately stops the output power default is Soft Cutoff 4 Low Voltage Protection Threshold Cutoff Threshold Low Medium High default is Medium For Li xx battery the cells quantity of a battery pack is calculated automatically or set manually Low Medium High cutoff voltage for each cell is 2 6V 2 85V 3 1V For example 10 cells Lipo when Medium cutoff voltage is set the cutoff voltage is 2 85 10 28 5V For Ni xx battery low medium high cutoff voltages are 0 45 60 of the startup voltage i e the initial voltage of the charged battery pack 0 means the low voltage protection function is disabled For example 20 cells NiMH battery fully charged voltage is 1 44 20 28 8V when Medium value is set the cutoff voltage is 28 8 45 12 96V 5 Start Mode Normal Soft Super soft default is Normal startup Normal is suitable for fixed wing aircraft Soft and Super soft are suitable for helicopter The initial soeed of Soft and Super soft mode is very slow so it will take 3 seconds Soft startup or 6 seconds Super soft startup from zero speed to full speed But if the startup process is completed i e The motor is running then the throttle is closed that means the throttle stick is moved to bottom position at 0 throttle and opened again
3. RPM Sensor The RPM sensor is an accessory of the high voltage speed controller Function It detects the voltage changes at the wires of brushless motor and then outputs the RPM signal This RPM sensor can work with some speed control systems for helicopters And one of its typical applications is to work as the RPM sensor for V Bar system made by Mikado www mikado heli de Specifications 1 Size 23mm L 10mm w 2mm H Note 2 Weight 6g Input and output wires are included A gt 1 It very important to set the Lipo battery cells quantity correctly otherwise the ESC will mistakenly calculate the cut off voltage 3 Working voltage 3 5V to 8 4V 1S to 2S Lipo gt C 2 In Lipo cells quantity setting process 1 long beep 5 short beep For example 2 long beep plus 2 short beep means a 12 4 Current 1 to 5mA B S cells lithium battery pack 1 long beep plus 1 short beep means a 6 cells lithium battery pack 5 Voltage range of the motor wires 2 to 14S Lipo 3 Ifyou are using lithium battery pack you d better set the Lipo cells quantity manually The voltage of a full charged lithium battery pack is 6 RPM range for 2 poles brushless motor 1000rpm to 300000rpm different from that of a discharged battery pack the more cells a battery pack has the more difficult for the ESC to automatically detect the 7 Working temperature 0 to 50 Celsius degree or 32 to 122 Fahrenheit
