Product Overview
The ABB DCS550-S02-0200-05 stands as the bullet-proof 200 A four-quadrant DC drive that keeps legacy 500 V DC motors alive in the age of AC supremacy. Launched in 2016 as the direct drop-in successor to the DCS500, the ABB DCS550-S02-0200-05 (order code 3ADT218466R0012) packs a fully-reversible anti-parallel thyristor bridge, built-in 25 A field exciter, and the legendary SDCS-CON-H01 control board into a 291 × 374 × 220 mm F2 frame that bolts straight onto the old DCS500 footprint—no panel rework, no new holes. One DriveWindow Light click auto-detects the ABB DCS550-S02-0200-05, clones the old parameter set, and delivers 0.1 % speed hold from 0 to 3000 rpm even when the mains sags 15 %.
At its core, the ABB DCS550-S02-0200-05 runs 12-pulse adaptive programming at 4 ms scan, executing torque memory, winder blocks, and 3-zone PID without a single external PLC. A built-in 18 A fan auto-derates to 70 °C without tripping, while the onboard FEX-4 field supply auto-tunes in 18 seconds and switches economy/full-field in 35 ms—slashing copper losses by 28 % on 150 kW winders. DriveComposer Pro streams live current waveforms at 20 kHz over Ethernet, turning a midnight fault call into a 9-minute hot-swap. From ArcelorMittal reversing mills to Australian port cranes, the ABB DCS550-S02-0200-05 is the invisible 200 A lifeline that turns 30-year-old DC assets into Industry 4.0 profit centers.

Main Features and Advantages
True 4-Q regeneration: The ABB DCS550-S02-0200-05 feeds braking energy straight back to the grid at 99 % efficiency—zero dynamic brake resistors, €42 k saved per mill on 200 kW reversing stands.
18-second auto-tuning: One-click armature and field wizards calibrate current loops to 0.2 % accuracy—commission a 1995 motor in the time it takes to drink a coffee.
Adaptive Programming 2.0: Drag-and-drop function blocks for taper tension, S-curves, and dual-motor master-slave—no PLC, no ladder, 60 % faster rollout.
Built-in field economy relay: Soft-ramps between 60 % and 100 % field in 35 ms, cutting magnetising losses by 28 % on constant-speed sections.
Live oscilloscope over Ethernet: DriveComposer streams armature current, field voltage, and torque at 20 kHz—spot bearing wear before the vibration alarm.
Hot-swap everything: Thyristor modules, fans, even the CON-H01 board—swap in 3 minutes while the motor coasts on inertia.
QR-code cloning: Scan the front plate, tap “Clone spare”, and the new ABB DCS550-S02-0200-05 boots identical in 11 seconds.
