24V / 350A CURTIS AC Motor Controller

Core part for vehicle AC motor motion controlling

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.

Specifications:

• PWM operating frequency: 15 kHz
• Electrical isolation to heatsink (min.): 500 VAC
• PWM operating frequency: 10 kHz
• Maximum encoder frequency: 15 kHz
• Maximum controller output frequency: 300 Hz
• Heatsink overtemperature cutoff: linear cutback starts at 85°C; complete cutoff at 95°C
• Heatsink undertemperature cutoff: complete cutoff at -40°C

It is supposed that the CURTIS AC Controller need to be programmed before applying to a specific application. For the buyer without AC MOTOR CONTROLLER PROGRAMMING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS 1234 AC Motor Controller Datasheet before making your purchase.

The 1234 AC motor controllers have a set of parameters which is very complicate. If you need to modify any controller parameter, please send us a message with the list of parameters to be modified. There is no extra cost for reprogramming the controller.

Typical application: MIMA, XILIN (RUYI), HANGCHA, HELI tow tractor / forklift.

As a professional supplier, we possess OEM programs (controller settings) of certain utility vehicles and forklifts. Buyers may contact us and send us the vehicle (forklift) information (manufacturer, model, year of production, etc.), for knowing if we can provide the controller with its OEM program. This 1234-2371 can also be programmed by CURTIS CURTIS Model 1313-4331 Handheld Programmer or CURTIS 1314 PC programming station. There is no extra cost for reprogramming the controller.
