Product Description

The ABB SDCS-COM-81 is a vital electronic circuit board that served as the main processor and communication interface for many ABB DC drives, particularly those in the DCS500 product line. It houses the CPU, memory, and specialized hardware required to run the drive’s firmware and control algorithms.

It manages the following core functions:

1. System Control: Executes the drive’s control software, handling speed, torque, and current loops.

2. User Interface: Manages the interface with the control panel (e.g., the SDCS-PAN-4 display).

3. Communication: Provides the hardware interface for fieldbus communication adapters (optional modules) and dedicated serial links.

Essentially, the SDCS-COM-81 is the brain that translates high-level commands (e.g., start, speed reference) into precise control signals for the drive’s power section.

Product Parameters

Product Advantages

• Integrated Control Logic: Provides a single, centralized platform for all high-level drive control functions, simplifying the overall system design.

• Real-Time Performance: Engineered to provide the necessary real-time processing capability for stable and dynamic DC motor control.

• Modular Communication: Supports the addition of various fieldbus adapters (e.g., PROFIBUS, Modbus) via dedicated slots, allowing for flexible network integration.

• Reliability: Built to ABB’s industrial standards, ensuring high operational reliability and longevity within harsh industrial settings.

Important Precautions

• ESD Protection: The SDCS-COM-81 is a highly sensitive electronic component. Strict Electrostatic Discharge (ESD) protection (i.e., grounded wrist strap) must be used during handling, installation, or removal to prevent irreversible damage.

• Firmware Backup: Before replacing the module, ensure the drive’s parameters and application program (firmware) are properly backed up, as the new board may need to be loaded with the correct configuration.

• Power Down Procedure: Always de-energize and lock out power from the drive unit and verify that all power capacitors are discharged before accessing or servicing the SDCS-COM-81.

• Compatibility Check: Due to the age of the DCS500 platform, always verify that the 3ADT314900R1002 part number is the correct replacement or upgrade for your specific drive unit, as minor hardware revisions exist.

Product Applications

The SDCS-COM-81 module is found at the heart of older ABB DC drive systems used in demanding industrial applications:

• Continuous Process Lines: Control of large DC motors in paper machines, extruders, and printing presses where precise speed and coordination are critical.

• Metals Industry: Powering and controlling the dynamics of rolling mills and tension control systems (winders/unwinders).

• High-Torque Applications: Used in cement kilns and other applications requiring smooth, high-torque starting and control characteristics from DC motors.
