General Functions

  • Extended fault detection and protection. The LED flashing pattern indicates the fault sources.
  • Monitoring battery voltage. It will stop driving if the battery voltage is too high and it will progressively cut back motor drive power as battery voltage drops until it cuts out altogether at the preset “Low Battery Voltage” setting.
  • Built-in current loop and over current protection.
  • Configurable motor temperature protection range.
  • Current cutback at low temperature and high temperature to protect battery and controller. The current begins to ramp down at 90°C case temperature, shutting down at 100°C .
  • The controller keeps monitoring battery recharging voltage during regenerative braking, progressively cutting back current as battery voltage rises then cutting off regen altogether when voltage goes too high.
  • Maximum reverse speed is configurable to half of max forward speed.
  • Configurable and programmable with a host computer though RS232 or USB. Provide free GUI which can run on Windows XP/2000, Windows 7 and Vista (recommend using Kelly standard USB to RS232 Converter).
  • Provision of a +5 volt output to supply various kinds of sensors, including Hall effect type.
  • 3 switch inputs which are activated by connection to Ground. Default to throttle switch, brake switch and reversing switch.
  • 3 analog inputs 0-5V inputs that default to throttle input, brake input and motor temperature input.
  • Configurable boost switch. Enables the maximum output power achievable if the switch is turned on.
  • Configurable economy switch. Limits the maximum current to half if the switch is turned On. Boost and Economy used the same pin as J2-6 (brake-AN). Needless to say, you may not use J2-6 (brake-AN) as brake analog regen mode if you want to use Boost or Economy function. Boost or Economy can’t be enabled at the same time in the user program.
  • Maximum reverse power is configurable to half power.
  • Enhanced regen brake function. A novel ABS technique provides powerful and smooth regen.
  • Configurable 12V brake signal input, instead of motor temperature sensor.
  • Optional joystick throttle. A bi-symmetrical 0-5V signal for both forwarding and reversing. If software version is 0406 or above, joystick can can be enabled or disabled in the user program now.
  • Configurable motor over-temperature detection and protection with the recommended thermistor KTY84-130 or KTY83-122.
  • 3 hall position sensor inputs. Open collector, pull up provided.
  • Optional supply voltage 8V-30V.
  • Cruise control. Can not be activated in reversing direction. If software version is 0406 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.
  • CAN Bus is not supported in KEB controller.

Features

  • 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.
  • Current multiplication: Take less current from battery, output more current to motor.
  • Easy installation: 3-wire potentiometer will work.
  • Standard PC/Laptop computer is used to do programming. No special tools needed.
  • User program provided. Easy to use. No cost to customers.
