CURTIS AC Controller 1236-5401 & 1236-6401
Forklift & Golf Cart AC motor speed controller
Notice: For the buyer without CONTROLLER APPLYING EXPERIENCE, please consult your cart/motor dealer and read carefully the CURTIS
1232-1238 AC Motor Controller Manual before making the purchase.
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.
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
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 1236, 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.
