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 1238 AC
Motor Controller Datasheet before making your purchase.
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 1238E-6501 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.
Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS
1238 AC Motor Controller Datasheet before making the purchase.
Notice: By default, we will deliver the controller with default setting of 72V / 550A / 0-5kΩ. For better applying the controller
to your system, the buyer should confirm with the seller the system voltage (48V, 60V, 72V or 84V) and the throttle type (0-5kΩ,
5k-0Ω or 0 – 5V, etc.).
Overview:
CURTIS 1238 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 1238, 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 1238 controllers are the
ideal solution for traction, hoist, dual drive, and other motor drive and vehicle control needs.
The 1238 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.
