SIEMENS SINAMICS DCM 6RA80 (English Version)

1. Metal Rolling Mill Main Drive

   SINAMICS DCM 6RA80 serves as the core drive for hot rolling mills, bar mills and tube rolling mills. It delivers stable low-speed high torque and wide field weakening speed range, supports fast dynamic response during steel biting and throwing. The four-quadrant regenerative function effectively handles frequent load fluctuations, suitable for new projects and retrofits of traditional DC rolling mill drives.

2. Winder & Unwinder for Metallurgical Strip Processing

   Applied to coiler, uncoiler and slitting line tension control in steel, aluminum and copper strip production. Built-in winding technology enables constant tension control with diameter calculation, dancer roll feedback and inertia compensation. It ensures consistent strip tension during acceleration, deceleration and steady operation to avoid material wrinkling or breakage.

3. Paper & Pulp Machine Main & Section Drives

   Deployed for paper machine main drives, calender rolls and reel winders. 6RA80 realizes precise speed synchronization between multiple drive points, stabilizes web tension throughout forming, pressing and winding processes. Seamless PROFIBUS/PROFINET communication allows easy integration with distributed automation systems for continuous paper production.

4. Plastic & Rubber Extruder & Calender Drive

   Ideal for single-screw extruders, two-roll calenders and internal mixers in plastic and rubber industries. Outstanding low-speed torque performance guarantees stable extrusion pressure and uniform material plasticization. Flexible torque limiting and speed regulation prevent screw blocking and protect mechanical transmission components.

5. Crane & Hoist Lifting Mechanism Drive

   Used for mine hoists, workshop overhead crane lifting drives and material winches. Four-quadrant operation supports stable lifting and lowering; regenerative braking feeds energy back to grid. The drive provides anti-sway logic, torque holding and overload protection to avoid load slipping during startup and stop.

6. Wire & Cable Drawing Machine Drive

   Adopted for thick wire drawing, intermediate drawing and fine wire drawing equipment. High-precision speed and torque control maintains constant wire tension during continuous drawing. Fast current loop response reduces wire breakage rate, meeting long-time stable operation requirements of metal wire production lines.

7. Printing Press Main Drive System

   Suitable for web offset printing, gravure printing and flexo printing main drives. It achieves accurate speed regulation and multi-axis synchronization, eliminates color registration deviation caused by speed fluctuation. Compact structure and rich interface options simplify cabinet layout for printing machinery OEMs.

8. Motor & Gearbox Test Bench Dynamometer

   Works as driving or loading dynamometer for motor, reducer and transmission test stands. Supports bidirectional torque and speed control, capable of simulating various working load conditions. High measurement accuracy enables reliable performance testing, aging test and characteristic curve recording.

9. Flying Shear & Cross-Cutting Equipment Drive

   Applied to flying shears, cut-to-length machines and flying saws in steel and non-ferrous metal processing. Fast dynamic response realizes precise position synchronization during flying cutting. Flexible DCC programming function simplifies cam curve and speed matching development without extra controllers.

10. Legacy DC Drive Retrofit Upgrade Project

    Perfect replacement for outdated SIMOREG DC drives. It reuses existing DC motors without mechanical modification, greatly cutting reconstruction cost and downtime. Consistent control philosophy and compatible communication protocols enable smooth system migration, widely used in upgrading old metallurgy, paper and lifting equipment.
