Features Include:
- Full-bridge field and half-bridge armature power MOSFET design, providing
- infinitely variable forward, reverse, drive, and brake control
- silent high frequency operation
- high efficiency
- Regenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heating
- Programmability through the 1313-4331 Handheld Programmer or 1314 PC Programming Station
- Complete diagnostics through the programmer and the internal Status LED
- Two fault outputs provide diagnostics to remotely mounted displays
- Continuous armature current control, reducing arcing and brush wear
- Automatic braking when throttle is reduced from either direction; this provides a compression braking feel and enhances safety by automatically initiating braking in an operator hands off condition
- Deceleration Rate, Load Compensation, and Restraint features prevent downhill runaway conditions; speed is controlled to within approximately 20% of level surface value
- MultiMode™ allows four user-selectable vehicle operating personalities
- Programmable to match individual separately excited motor characteristics
- Meets or exceeds EEC fault detect requirements
- Vehicle top speed is controlled and limited in each mode
- Linear temperature and undervoltage cutback on motor currents; no sudden loss of power under any thermal conditions
- High pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startup
- Creep speed adjustable from 0% to 25% in each mode
- Continuous diagnostics during operation, with microprocessor power-on self-test
- Internal and external watchdog circuits ensure proper software operation
- Programmable coil drivers provide adjustable contactor pull-in and holding voltages
- Hour-meter enable output is active whenever the controller is providing motor current
- Optional Electromagnetic Brake Driver provides automatic control of an electromagnetic brake or other similar function
- Optional Reverse Signal Driver provides a low signal any time the vehicle is driving or braking in reverse
- Optional Auxiliary Driver provides a low signal to power an auxiliary contactor or other similar function
- Driver outputs are short circuit protected and provide built-in coil spike protection
- Controller is programmable to provide throttle control of motor speed, applied motor voltage, or motor torque
- Can be configured for CAN Bus compatibility
