| Solution
for Sheet Cutter for Paper and Cardboard
The solution is based on following main components:
- MASTERDRIVE MC - AC Servo Drives (3 to 250 kW) for sheet
cutter, unwind, conveyors, vacuum stop, stackers with regenerative
power supply module.
- Low inertia servo motor (1FT6/1FK7)
- SIMADYN D T400 Sheet Cutter control software
- SIMATIC S7-400 PLC
- WinCC - SCADA HMI system and visualization
General
Rewinder Specifications:
- Sheet cutter for paper & paper board
- Cutting up to 200m/min with 0.1mm accuracy
- Synchronization of rotary cutter with line speed
Main
features include:
- Programmable angular control for synchronous sheet cutter
- Selectable sheet length
- Soft travel curves (sin/cos) to protect the mechanics
- Cutting curve for optimum cutting speed
- KP-adaption speed control for increased cutting accuracy
- Compensation for variable mass moment of inertia (pendulum
moment)
- Friction compensation
- Torque pre-control for acceleration
