5360 mm rewinder drive control
5360 mm width · 2200 m/min · double-drum winding
Overview
A complete electrical drive control system for a wide, high-speed double-drum rewinder running at 2200 m/min. We engineer the drive architecture, control cabinets, PLC logic and operator interface, then commission the line on site.
Control architecture
An Inovance SLM rectifier/regenerative unit feeds a common DC bus shared by all ABB ACS880 sectional inverters, so braking energy is returned to the grid instead of dissipated as heat. A Siemens SIMATIC S7-1500 PLC coordinates start/stop, speed, tension, rider-roll pressure, length/diameter counting and deceleration stop; field and control levels communicate over PROFINET industrial Ethernet.
Technical highlights
- Constant-tension winding from empty core to finished roll
- Bottom-roll torque difference control
- Rider-roll pressure regulation
- Ultrasonic roll-diameter sensing
- Constant-tension deceleration stop
