DC Drive Control Solution – ABB SDCS-AMC-DC-2 | DCS800 / DCS400 Series
Where This Product Is Used
The ABB SDCS-AMC-DC-2 (part number 3ADT312700R0001) is the Advanced Motor Control board at the heart of ABB’s DCS800 and DCS400 series DC drive systems. It is deployed across demanding industrial environments where precise, high-reliability DC motor control is non-negotiable:
- Steel & Metal Processing: Rolling mills, wire drawing machines, and coil winding lines requiring tight speed and torque regulation under heavy cyclic loads.
- Paper & Pulp Industry: Winder/unwinder drives, refiner drives, and section drives on paper machines where web tension control is critical.
- Mining & Minerals: Hoist drives, conveyor systems, and crusher drives operating in harsh, high-duty-cycle conditions.
- Marine & Offshore: Anchor windlass, crane, and winch drives requiring regenerative braking and four-quadrant operation.
- Plastics & Rubber Extrusion: Extruder screw drives and calendar roll drives demanding smooth, ripple-free torque output.
- Test Bench & Dynamometer Systems: Motor test rigs requiring high-bandwidth current and speed control loops.
- Crane & Hoist Applications: Bridge cranes, gantry cranes, and overhead hoists with regenerative load handling.

Why Engineers Specify This Model
- Drop-in Replacement: Direct plug-in replacement for failed SDCS-AMC-DC-2 boards in existing DCS800/DCS400 installations — no drive cabinet redesign required.
- High-Bandwidth Control: DSP-based current and speed loops deliver fast dynamic response, essential for tension-critical and position-critical processes.
- Fiber-Optic DDCS Bus: Noise-immune communication between the AMC board and gate unit boards (SDCS-PIN) eliminates interference in high-power thyristor environments.
- Scalable I/O Architecture: Modular expansion via SDCS-IOB-3 and SDCS-COM boards allows the same AMC board to serve simple standalone drives or complex multi-drive systems.
- Long Service Life: ABB’s industrial-grade PCB design is rated for continuous operation in demanding environments, reducing unplanned downtime.
- Proven Global Install Base: Tens of thousands of DCS800 drives in service worldwide — spare board availability and engineering support are well-established.

Application-Specific FAQ
Q: Is the SDCS-AMC-DC-2 compatible with both DCS800 and DCS400 drives?
A: The SDCS-AMC-DC-2 is primarily designed for the DCS800 series. DCS400 uses a different control board architecture. Please confirm your drive model and firmware version with us before ordering.
Q: Can I replace just the AMC board without replacing the entire drive?
A: Yes. The SDCS-AMC-DC-2 is a field-replaceable module. In most cases, swapping the board and restoring parameters from a backup (or re-commissioning via DriveWindow) restores full drive operation without replacing the power section.
Q: Do I need to re-tune the drive after replacing the AMC board?
A: If you have a parameter backup from the original drive, parameters can be restored via ABB DriveWindow software. Without a backup, the drive will require re-commissioning including autotune of current and speed regulators.
Q: What firmware version does this board support?
A: The SDCS-AMC-DC-2 supports ABB DCS800 firmware. Firmware can be upgraded in the field. Contact us to confirm the firmware version shipped with your unit.
Q: Do you supply the SDCS-AMC-DC-2 for OEM machine builders?
A: Yes. We supply OEM new, tested surplus, and refurbished units. Volume pricing and blanket order arrangements are available for machine builders and system integrators.
Q: What is your lead time for this part?
A: In-stock units ship within 1 business day. Out-of-stock units are typically sourced within 3–10 business days depending on global availability. Contact us for a firm lead time quote.
