It is necessary that the Curtis AC Controller is programmed before applying to a specific application. For a customer without AC Motor Controller Programming knowledge or experience, please consult your motor dealer and carefully read the Curtis 1236 AC Motor Controller Data-sheet before making your purchase.

Our knowledgeable technicians possess OEM programs (controller settings) of certain utility vehicles and forklifts. Customers may contact us and send us the vehicle or forklift information (manufacturer, model and year of production), to see see if we can provide the controller with its OEM program.

Product Overview

Curtis 1236 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 OEM developed 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 1236E, 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 1236 controllers are the ideal solution for traction, hoist, dual drive, and other motor drive and vehicle control needs.

The 1236 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.

Features

• Increased Performance, Improved functionality
• Higher performance form, fit and functional replacements for earlier Curtis Model 1236 AC controllers.
• CE marked as a programmable safety device under EN ISO 13849-1.
• Models available for 350 output at 48-80V 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

• Easily programmable through the Curtis Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
• 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
