The drive systems we engineer are built in three levels. At the field level, all-digital AC inverters run each motor with encoder closed-loop speed feedback. At the control level, a SIMATIC PLC acts as the multi-level control core — start/stop, speed, tension, interlocking and data management. At the operator level, an HMI and console give the plant team a live window on the line.
Keeping the busbar and control parts separated, with the field and control levels on a shared industrial-Ethernet network, means every node reads the same live state. That is what lets speed-chain, load sharing and tension loops act as one coordinated system rather than a pile of separately tuned drives.
For both our winder and paper-machine packages this three-level structure is the backbone: it is what lets a single team take the system end to end, from cabinet design to on-site commissioning.
