Overview:
CURTIS 1244-6661(600A)motor controllers deliver smooth power unlike any previous vehicle control system. They provide unprecedented flexibility and power through inclusion of a field-programmable logic controller embedded in a state-of-the-art motor controller.
The embedded logic controller runs a fully functional field-oriented AC motor control operating system (OS) that can be user-tailored via parameter modification. The OS also contains logic to execute OEMdeveloped software, called VCL, that can be used to enhance the controller capabilities beyond the basics.
VCL (Vehicle Control Language) is an innovative software programming language developed by CURTIS. Many electric vehicle functions are uniquely built into the VCL code, and additional functions can be OEM-controlled using VCL code. VCL opens new avenues of customization, product differentiation, and responsiveness to the market.
The CAN bus communications included, as well as in many other CURTIS products, allow these AC induction motor controllers to be part of an efficient distributed system. Inputs and outputs can be optimally shared throughout the system, minimizing wiring and creating integrated functions that often reduce the cost of the system.controllers are the ideal solution for traction, hoist, dual drive, and other motor drive and vehicle control needs.
Key Features:
Increased Performance, Improved functionality
Higher performance form, fit and functional replacements for earlier CURTIS Model.
CE marked as a programmable safety device under EN ISO 13849-1.
Models available for 550 output at 48-84V 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 meter.
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.
