Features Include:

Full-bridge field and half-bridge armature power MOSFET design, providinginfinitely variable forward, reverse, drive, and brake controlsilent high frequency operationhigh efficiencyRegenerative braking, providing longer operation on a single battery charge and reducing motor brush wear and motor heatingProgrammability through the 1313-4331 Handheld Programmer or 1314 PC Programming StationComplete diagnostics through the programmer and the internal Status LEDTwo fault outputs provide diagnostics to remotely mounted displaysContinuous armature current control, reducing arcing and brush wearAutomatic 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 conditionDeceleration Rate, Load Compensation, and Restraint features prevent downhill runaway conditions; speed is controlled to within approximately 20% of level surface valueMultiMode™ allows four user-selectable vehicle operating personalitiesProgrammable to match individual separately excited motor characteristicsMeets or exceeds EEC fault detect requirementsVehicle top speed is controlled and limited in each modeLinear temperature and undervoltage cutback on motor currents; no sudden loss of power under any thermal conditionsHigh pedal disable (HPD) and static return to off (SRO) interlocks prevent vehicle runaway at startupCreep speed adjustable from 0% to 25% in each modeContinuous diagnostics during operation, with microprocessor power-on self-testInternal and external watchdog circuits ensure proper software operationProgrammable coil drivers provide adjustable contactor pull-in and holding voltagesHour-meter enable output is active whenever the controller is providing motor currentOptional Electromagnetic Brake Driver provides automatic control of an electromagnetic brake or other similar functionOptional Reverse Signal Driver provides a low signal any time the vehicle is driving or braking in reverseOptional Auxiliary Driver provides a low signal to power an auxiliary contactor or other similar functionDriver outputs are short circuit protected and provide built-in coil spike protectionController is programmable to provide throttle control of motor speed, applied motor voltage, or motor torqueCan be configured for CAN Bus compatibility
