Here you can find the right settings for your Sondors eBike generic LCD! KT LCD3 settings for Sondors buy a LCD here: klick Max. Speed: leave it, or set it to 25 km/h Wheel Diameter: 29 for 4.9" tires, 28 for 4.0" Metric and Imperial Units: your choice P1 = 100 (Motor Characteristic Parameter Setting Mode, 1 - 255) P2 = 6 (Wheel Speed Pulse Signal Setting Mode, 0 - 6) P3 = 1 (Power Assist Control Mode, 0 or 1) P4 = 0 (Handlebar Startup Mode, 0 or 1) P5 = 12 (Power Monitoring Mode, 0 - 40) C1 = 01 (Power Assist Sensor and Parameter Select Mode, 00 - 07) C2 = 0 (Motor Phase Classification Coding Mode, 0 - 7, 0:sin wave) C3 = 8 (Power Assist Ratio Gear Initialization Mode, 0 - 8 ) (C3=6 WARNING! Bike starts running forward on it’s own at power up!) C4 = 0 (Handlebar Function Setting Mode, 0 - 4) C5 = 10 (Controller Maximum Current Adjustment Mode, 00 - 10) C6 = 3 (Backlight Brightness Adjustment Mode, 1 - 5) C7 = 1 (Cruise Function Setting Mode, 0 or 1) C8 = 1 (Motor Operating Temperature Display Mode, 0 or 1) C9 = 0 (Startup Password Setting Mode, 0 or 1) C10 = n (Automatically Restore Default Setting Mode, n or y) C11 = 0 (Attribute Selection Mode, 0 - 2) C12 = 4 (Controller Minimum Voltage Adjustment Mode, 0 - 7) C13 = 0 (Brake energy recovery - recuperation - only works with the corresponding controller, 0 - 5) C14 = 2 (Coordination of support levels, 1 - 3, 2 = standard) (description of the C parameters follows) Step by step / Details What you should now to set up your KT LCD3 display: General Settings: Under power off status, hold the „power“ button long, the meter is turned on. Within 5 seconds after boot-up, hold „up“ and „down“ simultaneously for about 2 seconds. Now you are in the settings menu. (between each setting parameter press „power“ to save and to get to the next parameter) Max. Speed: leave it For Europe: set it to 25 km/h to be on the legal side. Wheel Diameter: set it to what it is: 29 inches Metric and Imperial Units: your choice After finishing metric/imperial unit settings, the speed and mileage units stop flashing. Within one minute after stoppong flashing, hold „up“ and „down“ simultaneously for about 2 seconds to enter the P parameter settings environment. Need values for our motor are (http://www.szbaf.com/en/components/component/motor/rm-g06350d.html): Cadence (Pulses/Cycle) 6/1 Reduction Ratio 1:5 Magnet Poles 20 P1 Motor Characteristic Parameter Setting Mode P1 is motor characteristic parameter setting mode. P1 = motor gear reduction ratio x number of rotor magnet pieces, just rounding if there’s any decimal. Sondors: Ratio 5 x 20 Magnet Poles = 100 = P1 P2 Wheel Speed Pulse Signal Setting Mode P2 is wheel speed pulse signal setting mode. If wheel generated 1 pulse signal by a revolution, P2 should be set as1. If wheel generated 6 pulse signals by a revolution, P2 should be set as 6. If users didn’t configure the pulse signal system, and then P2 parameter setting can be 0. The setting range of P2 should be between 0-6. 0 : motor hall sensor only (speed is only shown while motor is working) 1-6: Pulses per Cycle Sondors: Cadence (Pulses/Cycle) 6/1 = 6 = P2 P3 Power Assist Control Mode P3 is for power assist control mode, when P3 parameter setting is1, power assist control mode is gear 5 of “imitation torque control” mode, when P3 parameter setting is 0, power assist control mode is gear 5 of “speed control” mode. P3 parameter needs to be determined according to the distributed function of the controller, its setting range is 0 or 1 Sondors: P3 = 1 P4 Handlebar Startup Mode P4 is handlebar startup mode. When P4 setting is 1, indicating the handlebar is under “non-zero startup” mode, namely, the handlebar can be effective only after startup the foot power assist. When P4 setting is 0, indicating the handlebar is under “zero startup” mode, the motor can be startup by the handlebar directly. P4 setting range is 0 or 1 Sondors: P4 = 0 P5 Power Monitoring Mode P5 is power monitoring mode, when P5 setting is 0, the power monitoring is the “real-time voltage” mode. Namely, it is the method to determine the battery capacity based on real-time battery voltage. When P5 equals to a specified parameter, the power monitoring is the “smart power” mode (this parameter is determined by the battery characteristics, ordinary 24V lithium is generally is 4-11, 36V lithium is between 5_15). P5 setting ranges from 0-40. E.g.: 9 = 24 V 12 = 36 V 15 = 48 V Sondors: 36 V -> P5 = 12 To exit the programming mode just hold „power“ some seconds. After finishing P parameter settings, the P5 parameter stops flashing. Within 1 minute after stopping flashing, hold “up” and “down” for about 2 seconds to enter the C parameter setting environment. C1 Power Assist Sensor and Parameter Select Mode C1 is power assist sensor and parameter select mode. C1 Quantum power assist sensors or similar products 00 5 magnet sensor 01 8 magnet sensor 02 10 magnet sensor 03 12 magnet sensor 04 Power assist sensors from other manufacturers 05 06 07 Sondors: C1 = 02 C2 Motor Phase Classification Coding Mode C2 is motor phase classification coding mode. It is served as identification parameter of different phases of the motor when using sine wave drive and the default value is 0. When C2 setting is 0, indicating that the used Quantum motor phase is an ordinary one. When the setting is a certain value, indicating a particular motor phase is used. C2 setting range is 0-7. Sondors: C2 = 0 C3 Power Assist Ratio Gear Initialization Mode C3 is initialization mode of power assist ratio gear. The setting range is 0-8 (gear). When C3 setting is 0, the meter is switched on, and the power assist ratio is at gear 0. When the setting is 1, the meter is powered on and the power assist ratio is at gear 1, and so on. Sondors: C3 = 8 C4 Handlebar Function Setting Mode C5 Controller Maximum Current Adjustment Mode C6 Backlight Brightness Adjustment Mode C7 Cruise Function Setting Mode Activate the Cruise Mode: C8 Motor Operating Temperature Display Mode C9 Startup Password Setting Mode C10 Automatically Restore Default Setting Mode C11 Attribute Selection Mode C12 Controller Minimum Voltage Adjustment Mode C13 Brake energy recovery - recuperation - only works with the corresponding controller C14 Coordination of support levels (C Parameters are following some time) Want a complete manual?
