The 'E' Advantage
A significant enhancement to the Curtis AC family, The 'E' models utilize
a powerful dual-microprocessor logic architecture to provide improved
performance and surpass the requirements of the latest international
functional safety standards.
Only AC can offer:
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 anycustom 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.
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. Models 1236E and 1238E are CANopen compatible and provide 20
VCLconfigurable CAN 'mailboxes', 6 more than earlier Curtis AC controllers.
Integrated System Controller-More than just a motor controller, they are also
powerful system controllers. They feature 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, these controllers 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
Increased Performance, Improved functionality
Higher performance form, fit and functional replacements for earlier Model
1236 and 1238 AC controllers.
CE marked as a programmable safety device under EN ISO 13849-1.
Models available for 350-800A output at 24-96V system voltages. These are true
2 minute RMS ratings, not short duration 'boost' ratings.
Enhanced 64MHz micro and additional FLASH memory doubles the available VCL
code space and provides more than twice the VCL execution speed.
Six additional VCL-configurable CAN 'mailboxes' significantly increases CAN
master capabilities.
Advanced Pulse Width Modulation techniques produce low motor harmonics,
low torque ripple and minimized heating losses, resulting in high efficiency
Overview:
The model 1244-5621 provides advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties and offers the highest levels of functional safety.
