CURTIS 1238 AC induction motor controllers deliver smooth electricity unlike any previous vehicle manage method. They give unparalleled overall flexibility and electrical power by way of inclusion of a subject-programmable logic controller embedded in a state-of-the-art motor controller.

The embedded logic controller operates a fully practical subject-oriented AC motor handle operating technique (OS) that can be user-customized via parameter modification. The OS also includes logic to execute OEMdeveloped application, called VCL, that can be utilized to increase the controller capabilities beyond the fundamentals.

VCL (Vehicle Manage Language) is an revolutionary application programming language designed by CURTIS. Many electric vehicle features are uniquely created into the VCL code, and added functions can be OEM-managed employing VCL code. VCL opens new avenues of customization, product differentiation, and responsiveness to the industry.

The CAN bus communications incorporated in the 1238, as well as in many other CURTIS products, let these AC induction motor controllers to be component of an effective distributed system. Inputs and outputs can be optimally shared throughout the method, minimizing wiring and making integrated functions that frequently reduce the price of the system. CURTIS 1238 controllers are the excellent solution for traction, hoist, dual drive, and other motor push and car manage needs.

The 1238 controllers are fully programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 Personal computer Programming Station. The programmer offers diagnostic and check capability in addition to configuration overall flexibility.
