DC PUMP SYSTEM CONTROLLER
MODEL 1298
Only Curtis AC can offer:
• Curtis VCL -Vehicle Control Language is an easy to
use programming language that allows vehicle developers
to write powerful logic functions and create a ‘virtual system
controller’. Curtis offers customers VCL development tools
and training. Curtis also provides a VCL service where Curtis
engineers will work with the OEM to create any custom VCL
code required.
• Indirect Field Orientation (IFO) vector control algorithm
generates the maximum possible torque and efficiency across
the entire speed range. Advanced Curtis IFO vector control
provides superb drive ‘feel’, improved speed regulation and
increased gradeability.
• Curtis Auto-Tune function enables quick and easy
characterization of the AC motor without having to remove
it from the vehicle. Curtis AC controllers are fully compatible
with any brand of AC motor.
• Dual-Drive functionality is standard, allowing correct
control of applications featuring twin traction motors. This
function ensures smooth and safe operation, minimal tire
wear and correct load sharing between the traction motors
at all times.
• Configurable CANbus connection allows communication
with other CANbus enabled devices. Model 1298 is
CANopen compatible and can be further customized and
configured using VCL.
DESCRIPTION
The Curtis Model 1298 combines advanced control of AC
induction traction motors with solid state DC hydraulic pump and
proportional valve control. It offers vehicle developers a highly
cost-effective combination of power and functionality in a very
compact integrated package.
APPLICATION
Designed primarily for class III material handling vehicles, such as
walkie stackers that require variable speed, or soft-start and softstop control of the lift and lower functions.
• Integrated System Controller - More than just a motor
controller, it is also powerful system controller. It features a
comprehensive allocation of multi-function I/O pins for use
as analog inputs, digital inputs, contactor coil drivers and
proportional valve drivers. In addition to this local I/O, this
controller can use VCL to map and configure the remote I/O
available on other CANbus devices, send messages to CAN
displays and thus control and monitor the entire system.
FEATURES
Complete system control
• High frequency, silent operation across the 0-300Hz stator
frequency range.
• Variable speed half-bridge DC pump output provides superior
regulation of pump motor speed and current demand.
• Fully programmable proportional valve and load-hold valve
drivers.
• Programmable options for variable speed or soft-start lift and
lower modes.

• Models available for 250A rms traction with 300A DC
pump, or 300A rms traction with 350A DC pump. These are
true 2 minute ratings, not short duration ‘boost’ ratings
MODEL 1298
F E A T U R E S continued
• Powerful operating system allows parallel processing of
vehicle control tasks, motor control tasks and user configurable
programmable logic.
Robust Safety and Reliability
• Advanced Pulse Width Modulation techniques produce low
motor harmonics, low torque ripple and minimized heating
losses, resulting in high efficiency.
• Fail-Safe power component design.
Unmatched Flexibility
• Insulated Metal Substrate power base provides superior heat
transfer for increased reliability.
• Redundant hardware watchdog timers.
• Reverse polarity protection on battery connections.
• Short circuit protection on all output drivers.
• Field upgradeable software.
• Integrated Battery state-of-charge algorithm and hour meter.
• Multi-ModeTM provides user-selectable vehicle operating
profiles.
• Thermal cutback, warning, and automatic shutdown provide protection to motor and controller.
• Rugged sealed housing and connectors meet IP65
environmental sealing standards for use in harsh
environments.
• Fully-featured generic software and VCL for typical
Warehouse Truck applications is included.
• Comprehensive programming options and VCL allow other
applications to be easily supported.
• Curtis hand-held or PC Windows programming tools provide
easy programming and powerful system diagnostic tools.
• Integrated status LED provides instant diagnostic indication.
Meets or complies with relevant US and
International Regulations

SYSTEM ACCESSORIES
The Curtis Model 840 LCD
Multifunction display contains 8 large,
easy to read characters to provide
display of battery discharge (BDI),
hour meter and error messages.
Built-in backlight is also available.
The Curtis model 1352 CANbus I/O
expansion module features 9 I/O
pins, including 6 proportional valve
drivers. This module can be used to
further expand the I/O capability of
Curtis AC motor controllers using VCL.
The Curtis Model 1313 Handheld
Programmer is ideal for setting
parameters and performing diagnostic
functions.
