The SDCS-CON-4 board excels in demanding applications requiring precise DC motor control with high reliability :
| Industry | Application |
|---|---|
| Steel & Metallurgy | Main drive control for reversing cold rolling mills (±0.1% speed regulation), winders, unwinders, and roll drives |
| Paper & Pulp | Section drive coordination in multi-section paper machines, maintaining tension control across reels, press sections, and dryer sections |
| Rubber & Plastics | Controlling large internal mixers (Banbury mixers) and high-output extruders during initial raw material mixing |
| Mining | Hoist drum control for mine shafts with four-quadrant operation and regenerative braking |
| Oil & Gas | Drawworks, mud pump, and rotary table control on drilling rigs |
| Marine | Thruster and winch control on offshore vessels |
| Cement | Rotary kiln main drive DC motor control under continuous low-speed, high-friction conditions |
The SDCS-CON-4 board installs in a dedicated slot inside the DCS800 drive housing, linking with the power interface board (SDCS-PIN-4) and fieldbus adapters through a high-speed backplane . It communicates with gate driver circuits, current sensors, and auxiliary power supplies to coordinate field excitation and armature control .
Parameter configuration is performed through ABB's DriveWindow 2 software, which provides guided wizards for motor identification, PID tuning, and I/O mapping . The board supports auto-tuning routines that measure motor inductance, resistance, and inertia to automatically optimize control loop gains .
For networked installations, the board supports multi-drive coordination via PROFIBUS DP V1, enabling master-follower configurations for synchronized section drives or electronic line shafting .
Please verify compatibility before ordering. Some sources indicate this board is also used in DCS500 and DCS600 series drives, while others specify DCS800 only . Please confirm your drive model and firmware requirements prior to purchase .
