SDCS-CON-2 3ADT309600R1 ABB Control board core control unit ACS1000 medium-voltage frequency converter

Product Overview

ABB SDCS-CON-2 (Model:) 3ADT309600R1 is the core Main Control Board of ABB ACS1000 series medium-voltage AC frequency converters and is a key component of the SDCS (System Drive Control System) architecture. This control board is responsible for the logical operations, PWM modulation, protection function execution, communication management and data interaction with the upper-level system of the frequency converter. It is the "brain" that ensures the high-precision and high-reliability operation of the ACS1000 frequency converter.

SDCS-CON-2 is widely used in scenarios with strict requirements for medium-pressure transmission performance, such as power, metallurgy, mining, oil and gas, ship propulsion, and large industrial pump/fan drive.

Core features

Core control function
Implement vector control and V/f control algorithms
Generate high-precision PWM signals to drive power units
It implements comprehensive protection logics such as overcurrent, overvoltage, overheating and ground fault
High-performance processor: Based on dedicated DSP and FPGA architecture, it ensures real-time control response
Multi-protocol communication support
The optical fiber is connected to the gate driver board (SDCS-GDN-x).
The RS-485 / RS-232 interface is used for local debugging
Supports Profibus DP and Modbus RTU (via optional communication modules)
