Product Description

The ABB SDCS-CON-3A is the main control printed circuit board (PCB) assembly used within older or specific models of ABB DC converter units (DC Drives).

• Type: Microprocessor-based Control Board / Control Unit.

• Function: It is the “brain” of the DC drive, responsible for executing the control software, including speed, torque, and current regulation, field control, sequential control, and communication with external systems (like PLCs or HMIs). It manages the firing pulses to the drive’s thyristor bridge.

• Design: The board contains the drive’s microprocessors, memory, communication ports, and interfaces for digital and analog I/O that connect to the drive’s main power circuit board (like the SDCS-IO board).

• Compatibility: It is specifically designed to fit into the drive’s hardware chassis and interface with other SDCS- series boards.

Product Specifications

Since the SDCS-CON-3A is a component board within a larger drive system, its specifications relate to its processing power and connectivity.

Product Advantages

• High Control Performance: Optimized for precise, rapid control of DC motor speed and torque, delivering high dynamic response essential for demanding industrial processes (e.g., metals, paper, cranes).

• System Integration: As a core ABB component, it ensures seamless integration and compatibility with other ABB automation products (AC800M PLC, ACS/DCS drives).

• Field Control: Includes capabilities for controlling the DC motor’s field current, which is essential for constant power operation at high speeds (field weakening).

• Reliability: Built to ABB’s high industrial standards, ensuring robust operation in harsh factory environments.

• Extensive Diagnostics: Provides detailed fault codes and logging capabilities, facilitating fast troubleshooting and reducing downtime.

Precautions

• Handling and ESD: The SDCS-CON-3A is a sensitive electronic component. Always handle it using proper Electrostatic Discharge (ESD) precautions (e.g., grounding straps) and avoid touching exposed components.

• Firmware: The board requires the correct drive control software (firmware) to be loaded, which must be compatible with the specific DC drive hardware and motor application.

• Configuration: Proper commissioning involves setting hundreds of drive parameters (PID loops, current limits, acceleration ramps) using the specialized ABB configuration software. Incorrect settings can damage the motor or mechanics.

• Replacement: When replacing a faulty board, ensure the new board is the exact model and that the original parameter backup is loaded to maintain machine operation.

• Ribbon Cables: Take extreme care when connecting and disconnecting the sensitive ribbon cables that link the control board to the I/O and power boards; incorrect insertion can damage pins.

Product Applications

The SDCS-CON-3A control board is central to applications requiring robust, high-performance control of DC motors in demanding industrial environments.

• Metal Industry:

  • Controlling rolling mills, winders, and rewinders where precise tension and speed control are critical.

• Paper and Printing:

  • Managing speed and tension on paper machines, coaters, and printing presses.

• Cranes and Hoists:

  • Providing reliable speed and torque control for heavy-duty overhead cranes and hoisting mechanisms.

• Extruders and Mixers:

  • Maintaining precise speed control for extruders and high-torque mixers in plastic or rubber industries.
