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.

Key Features:

• CURTIS Model: 1236-5401 / 1236-6401
• Nominal input voltage: 36-48V (1236-5401) or 48-80V (1236-6401)
• 2 Minute RMS Current Rating (amps): 450A (1236-5401) or 350A (1236-6401)
• MOSFET overtemperature cutback: linear cutback starts at 100°C; complete cutoff at 110°C
• MOSFET undertemperature cutback: approx. 50% motor current at -25°C; complete cutoff at -40°C
• All low power connections are made through a single 35-pin AMPSEAL connector
• Throttle Type: 0-5K Ω (default setting), flexible throttle circuitry accommodates a variety of throttle types: 5kΩ–0, 0–5kΩ, 0–5V, etc.
• Operating Ambient Temperature Range: -40°C to 50°C
• Internal Heatsink Operating Temperature Range: -40°C to 95°C
• Storage Ambient Temperature Range: -40°C to 95°C
• Package environmental rating: IP65
• Dimensions: W165 × L232 × H85 mm (6.5" × 9.1" × 3.4")
• Net Weight: 4.12 kg (9.1 lbs)

Features Include:

• High efficiency, field-oriented motor control algorithms
• Advanced Pulse Width Modulation technology for efficient use of battery voltage, low motor harmonics, low torque ripple, and minimized switching losses
• Extremely wide torque/speed range including full regeneration capability
• Smooth low speed control, including zero speed
• Adaptation of control algorithm to motor temperature variation so optimal performance is maintained under widely varying conditions
• Real-time battery current, motor torque, and power estimates available
• Power limiting maps allow performance customization for reduced motor heating and consistent performance over varying battery state-of-charge
• Powerful operating system allows parallel processing of vehicle control tasks, motor control tasks, and user configurable programmable logic
• A wide range of I/O can be applied wherever needed, for maximum distributed system control
• Internal battery-state-of-charge, hourmeter, and maintenance timers
• Easily programmable through the Curtis 1313-4331 Handheld Programmer or 1314 PC Programming Station
• CAN bus connection allows communication with other CAN bus enabled system components; protocol meets CANopen standards; other 11-bit identifier field CAN protocols can be custom configured through VCL
• Field-programmable, with flash downloadable main operating code
• Thermal cutback, warning, and automatic shutdown provide protection to motor and controller
• Rugged sealed housing and connectors meet IP65 environmental sealing standards for use in harsh environments
• Insulated metal substrate power base provides superior heat transfer for increased reliability
• Built-in Dual Drive software allows easy setup and control of typical dual-drive vehicles, without VCL
