Product Paramenters
Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS
1244 SepEx Controller Manual before making the purchase.
Notice: By default, we will deliver the controller with default setting of 72V / 600A / 5k-0Ω. For better applying the controller
to your system, the buyer should confirm with the seller the throttle type (0-5kΩ, 5k-0Ω or 0 – 5V, etc.).
Overview:
CURTIS 1244 MultiMode™ controllers are separately excited motor speed controllers designed for use in a variety of material
handling vehicles. These programmable controllers are simple to install, efficient, and cost effective. Typical applications
include low lifts, stackers, fork lifts, reach trucks, personnel carriers, counterbalance trucks, order pickers, boom trucks, and
other industrial vehicles.
The 1244 MultiMode™ controller offers smooth, silent, cost effective control of motor speed and torque. A four quadrant,
full-bridge field winding control stage is combined with a two quadrant, half-bridge armature power stage to provide solid state
motor reversing and regenerative braking power without additional relays or contactors. The 1244 controller can also be specified
to be compatible with CAN Bus communication systems.
The 1253 controller is fully programmable through a CURTIS 1313-4331 Handheld Programmer or 1314 PC Programming Station. The
programming device provides diagnostic and test capability in addition to configuration flexibility.
Key Features:
* CURTIS Model: 1244-6661
* Norminal Battery Voltage (Volts): 72V (default setting), 84V, 60V or 48V
* Amature Current Limit (amps): 600
* Amature 1 Minute Current Rating (amps): 600
* Amature 1 Hour Current Rating (amps): 140
* Field 2 Minute Current Rating (amps): 50
* Dimensions: L229xW178xH81 mm
* Net Weight: 3.9 kg
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
