Product Description
Overview:
CURTIS 1234 AC induction 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 in the 1234, 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. CURTIS 1234 controllers are the
ideal solution for traction, hoist, dual drive, and other motor drive and vehicle control needs.
The 1234 controllers are fully programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
The programmer provides diagnostic and test capability in addition to configuration flexibility.
