Curtis 1244 Manual, Rev. E
1 — OVERVIEW
Like all Curtis motor controllers, the 1244 oers superior operator control of
the vehicles motor drive speed. 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 handheld programmer and 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 o 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 o (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
