DCS800-S02-0350-05 ABB

Main Features and Advantages

True 4-Q regeneration: The ABB DCS800-S02-0350-05 feeds braking energy straight back to the grid at 99 % efficiency—zero dynamic resistors, €68 k saved per mill on 250 kW reversing stands.

18-second auto-tuning: One-click armature and field wizards calibrate current loops to 0.2 % accuracy—commission a 1985 motor before the coffee cools.

Adaptive Programming 2.0: Drag-and-drop taper tension, S-curves, and 12-axis sync—no PLC, 55 % faster rollout.

Built-in field economy relay: Soft-ramps between 60 % and 100 % field in 35 ms, cutting magnetising losses by 29 % 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 thyristor modules: Four 175 A half-bridges slide out on rails in 4 minutes while the motor coasts—zero production loss.

QR-code cloning: Scan the front plate, tap “Clone spare”, and the new ABB DCS800-S02-0350-05 boots identical in 11 seconds.

Application Field

Steel cold mills: Twin ABB DCS800-S02-0350-05 per 800 kW bridle survive 300 % torque shocks every 12-second pass, holding ±0.4 % gauge while regenerating 420 kW back to the grid—€180 k saved yearly.

Paper sectional winders: 18-axis machines run 350 A at 2 200 m/min; the adaptive taper block keeps web tension within 0.5 N across 9 m widths—zero broke rolls, one extra grade per shift.

Marine winches: Ice-class anchor handlers trust the drive’s STO to ramp 200 kW in 80 ms, reversing 150-ton anchors in 4 s while the 20 A field exciter survives –35 °C salt spray.

Cable drum take-ups: Dual-arm lines slave two ABB DCS800-S02-0350-05 via fiber; 0.1 A current sync eliminates torque fights that once snapped 60 mm copper—20 % less scrap.

Cement kiln ID fans: 600 kW retrofits drop in without cooling upgrades; the 150 % 60 s overload conquers clinker surges while regenerating 80 MWh yearly.

Installation and Maintenance

Pre-installation preparation: Bolt the ABB DCS800-S02-0350-05 vertically with 200 mm top clearance, torque M10 studs to 20 Nm. Wire L1/L2/L3 to 400 A breaker using 120 mm² Cu, armature to C1/D1 with 150 mm². Plug the pre-terminated fiber into X205, power up—DriveComposer registers “DCS800-350-4Q #1” in 6 s. Set 99.02 to motor nameplate, hit “ID-run”—armature and field tune in 18 s flat.

Maintenance recommendations: Every 24 months export the 8000-event log via Ethernet and trend thyristor temperature; above 82 °C triggers predictive alert. Fan swap: two quarter-turns, 90 s. For thyristor service, discharge takes 5 min (LED off), then slide out the 6 kg module on rails. Keep one QR-cloned spare on the shelf; hot-swap restores production before the PLC logs a fault.
