Paper-machine sectional drive and coordination
A paper machine is many independently driven sections that must behave as one continuous process. We engineer the drive backbone, speed chain, load sharing and operator control as one coordinated system.
The system behind coordinated control
Drives, motors, control cabinets and industrial communication work as one engineered system.
Conceptual visualization — not a client project or site record.Where this solution fits
- New sectional-drive systems for paper-machine lines
- Modernization of aging DC or fragmented AC drive systems
- Lines with unstable draw, uneven load sharing or limited operating visibility
- Projects that need drive, PLC/MCS, power distribution and commissioning under one engineering scope
Engineering scope
- 01Sectional AC drive architecture and motor/drive coordination
- 02Common-DC-bus power architecture with regenerative energy handling
- 03Speed-chain, draw and master/slave load-sharing control
- 04PLC/MCS, HMI, industrial communication and operating modes
- 05Electrical design, cabinets, installation interfaces and on-site commissioning
How the control is structured
- 01
Speed-chain coordination
A lead reference and controlled ratios coordinate adjacent sections so line-speed changes propagate without creating abrupt draw changes.
- 02
Adaptive load sharing
Master/slave torque distribution follows operating conditions rather than relying on one fixed ratio.
- 03
Shared DC backbone
Multiple inverters exchange energy through a common DC bus; front-end selection follows line scale, braking demand and power-quality requirements.
- 04
Three-level control
Field drives, the PLC/MCS control core and the HMI/operator layer share one live machine state.
Typical deliverables
- Control and drive architecture
- Electrical drawings and I/O definition
- PLC/HMI/MCS software
- Cabinet integration and drive configuration
- Commissioning records and operating training

Speed-chain control and load sharing on a sectional paper machineA sectional paper machine is many drives that must behave as one. Speed-chain control keeps the draw constant; master/slave load sharing keeps the torque where it belongs.Read insight →Load sharing that adapts to the gradeOn our paper-machine drives the master/slave load-sharing ratio is not fixed — it follows grade, basis weight, speed, wire tension and vacuum automatically.Read insight →Why we use a 12-pulse rectifier on wide paper machinesA big common-DC-bus line fed by one rectifier can pollute the supply with harmonics. A 12-pulse front end is our standard answer for wide, high-speed machines.Read insight →Final motor ratings, rectifier topology, network architecture and performance targets depend on the machine process, installed equipment, supply conditions and agreed acceptance criteria.
