The CURTIS 1228 MultiMode™ controller is a permanent magnet motor speed controller designed for use in mobility aid scooters and other small electric vehicles, such as sweeper/scrubbers.

Overview:

       The 1228-2901 offers smooth, silent, cost effective control of motor speed and torque. A four quadrant, full bridge power output stage provides for solid state motor reversing and full braking power without additional relays or contactors.
       The 1228-2901 controller is fully programmable, via the CURTIS Model 1313-4401 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.

• Throttle Type: By default, the Throttle Type of controller 1228-2901 is set as Type "0". The controller 1228-2901 can be programmed to accept single-ended, wigwag, or inverted wigwag signals from a 5kΩ, 3-wire pot or from a 5V throttle. The throttle input signal type options (Types "0" through "5" in the Throttle Type programming menu) are listed as below:
  • 0 = wigwag pot or voltage throttle
  • 1 = inverted wigwag pot or voltage throttle
  • 2 = single-ended pot; maximum speed = 5kΩ
  • 3 = inverted single-ended pot; maximum speed = 0
  • 4 = single-ended voltage throttle; maximum speed = 5V
  • 5 = inverted single-ended voltage throttle; maximum speed = 0
• Dimensions: W91xL156xH43 mm
• Net Weight: 0.6 kg
• Regulatory compliance: Designed to ANSI RESNA WC 14/21, ISO 7176-14, ISO 7176-21, and EN 12184. Documentation available to support 510K FDA filings.
• Operating ambient temperature range: -25°C to 50°C
• Storage ambient temperature range: -40°C to 70°C
• Package environmental rating: IP40

Features Include:

• Full bridge power MOSFET design, providing
  • infinitely variable forward, reverse, drive, and brake control
  • silent high frequency operation
  • high efficiency
• Complete diagnostics through the CURTIS programmer and a status LED
• Full compliance with all applicable international standards
• Available for single-ended or wigwag 5kΩ potentiometer throttles and 5V throttles (both standard full stroke and restricted range)
• MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions (for example, indoor/outdoor)
• Speed limit input provides linear variable speed limiting when an external speed limit pot is used
• Current limiting in both driving and regenerative braking modes
• Load compensation stabilizes speed on ramps and over obstacles
• Speed scaler eliminates variations in maximum speed that would otherwise result from variations in battery charge levels
• High pedal disable (HPD) function with lockout monitors status of the throttle during turn-on and prevents operation until the throttle has been returned to neutral
• Key-off deceleration function provides a controlled deceleration if the keyswitch is turned off while driving
• "E Stop" provides a faster deceleration for emergency stops
• Seat lift function simplifies the wiring required to implement seat lift in DME scooter applications
• Comprehensive fault detection monitors main contactor, output stage, throttle demand vs. output, etc., and disables the drive functions if any conditions are outside specified limits
• ISO 7176 compliant throttle fault detection circuitry inhibits driving if throttle pot signal goes out of range for any reason
• Missing/shorted brake detection forces neutral in the event of an open or shorted brake circuit
• Anti-rollback/anti-roll-forward function sets brake delay according to speed and direction for improved braking response and minimized rollback on hills, etc.
• Reverse beeper option can be used to drive a low current dc horn when vehicle is in reverse
• "Push" input electrically releases brake for key-on pushing (requires that the vehicle be stopped first)
• "Push-Too-Fast" feature guards against unpowered vehicle runaway by powering up and regulating motor voltage to limit vehicle speed
• Inhibit input disables the controller and puts the vehicle in a safe state during charging, etc.
• Power saver deactivates the main relay after 25 seconds of nonoperation and deactivates the entire controller after the programmed sleep delay has elapsed
• BDI output can be used to provide data to a voltmeter; the BDI output can be "stuffed" (optional) in order to display the battery state of charge during battery charging even while the keyswitch is turned off
• Undervoltage cutback function protects against operation at low battery voltage
• Overvoltage protection shorts the motor and disables driving in the event of excessive battery voltage
• Thermally protected
• Reverse polarity protected (battery input)
• Easily programmable through the CURTIS Model 1313-4401 Handheld Programmer or 1314 PC Programming Station.
