The 'E' difference
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.

DESCRIPTION
Curtis Models 1236E and 1238E provide advanced control of AC induction motors performing on-vehicle traction drive or hydraulic pump duties. They offer vehicle developers a highly cost-effective combination of power, performance and functionality.

APPLICATION
Designed primarily for use on medium to large material handling vehicles such as counterbalance or warehouse trucks. The Model 1236E is equally suitable for industrial utility vehicles. The larger Model 1238E is also intended for use on all heavy-duty applications such as Tow Tractors and Airport Ground Support Equipment (GSE).

Only Curtis AC can offer:
•• Curtis VCL:trademark:-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. 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 Curtis 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.

Unmatched Flexibility
•• Programmable for either traction or pump applications.
•• Field upgradeable software.
•• Integrated Battery state-of-charge algorithm and hour meters.
•• 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.

Robust Safety and Reliability
•• Dual Microprocessor architecture cross-checks critical circuits, logic, and software functions to ensure the highest possible functional safety performance level is achieved.
•• Insulated metal substrate power-base provides superior heat transfer for increased reliability.
•• Fail-Safe power component design
•• Reverse polarity protection on battery connections.
•• Short circuit protection on all output drivers.
•• 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.
