or above,cruise control can be enabled or disabled in the user program now.If you hold
throttle at certain position about 3-4 seconds,the controller will get into Cruise control.
(22) CAN Bus is not supported in KEB controller.
Caution!
Regeneration has braking effect but does not replace the function of a mechanical
brake. A mechanical brake is required to stop your vehicle. Regen IS NOT a safety feature!
Controller may stop regen, without warning, to protect itself or the battery(it won’t protect you!).
2.2 Features
•Specially designed for electric bicycle and scooter.
•Intelligence with powerful microprocessor.
•Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency.
•Electronic reversing.
•Voltage monitoring on 3 motor phases, bus, and power supply.
•Voltage monitoring on voltage source 12V and 5V.
•Current sense on all 3 motor phases.
•Current control loop.
•Hardware over current protection.
•Hardware over voltage protection.
•Support torque mode, speed mode, and balanced mode operation.
•Configurable limit for motor current and battery current.
•Battery current limiting available, doesn’t affect taking off performance.
•More startup current ,can get more startup speed.
•Low EMC.
•LED fault code.
•Battery protection: current cutback, warning and shutdown at configurable high and low
battery voltage.
• Rugged aluminum housing for maximum heat dissipation and harsh environment.
•Rugged high current terminals, and rugged aviation connectors for small signal.
•Thermal protection: current cut back, warning and shutdown at high temperature.
•Configurable 60 degree or 120 degree hall position sensors.
• Support motors with any number of poles.
•Up to 40,000 electric RPM standard. Optional high speed 70,000 ERPM, and ultra high speed
100,000 ERPM. (Electric RPM = mechanical RPM * motor pole pairs).
•Brake switch is used to start regen.
•0-5V brake signal is used to command regen current.
•Support three modes of regenerative braking: brake switch regen, release throttle regen,
0-5V analog signal variable regen.
• Configurable high pedal protection: the controller will not work if high throttle is detected at
power on.
