WINDER SOLUTION

Variable Speed drives are ideally suited to provide accurate and effective control of material tension and have become the standard solution for winder applications, providing :

• The ability to either motor or regenerate, enabling use in both coiling and uncoiling applications
• Reduced running cost compared with mechanical equivalents
• Improved reliability
• A wide range of control & flexibility
  

The final tension control solution will depend upon the material to be processed, the speed and diameter range over which it is to be run. Simple low performance systems can be based upon straight forward open loop torque prediction, whilst more sensitive applications may require the tension loop to be closed by feedback from a load cell. Some materials are better handled by running the drive in speed control with a dancer roll measuring the tension and modulating the winder speed.

This software provides a packaged Winder drive which caters for all these options and is easy to set up and integrate into your machine.

All the system control is achieved by one SM-Applications Plus fitted within the drive. Interfacing can be analogue or digital, making the package equally suited to refurbishment projects or new systems employing HMI and fieldbus technology

The Winder Solutions software has the following features:

• All data entry for set up in engineering units
• Self calibration ensures easy start up
• Simplified fieldbus configuration gives quick integration into CTNet or third party field bus
• Operates in either Torque or Speed mode
• Includes PID trim of torque or speed output where direct tension measurement is available
• Set-points and feedbacks can be derived as direct analogue signals or by fieldbus
• Analogue output for control of Dancer set point via E/P transducer (allows Taper Tension using Dancer control)
• Direct measurement or calculated diameter
• Diameter calculated from speed ratio or lap count
• Draught compensation for reduction mill applications
• Taper Tension with adjustable start diameter
• Accurate inertia compensation
• Advanced loss compensation facility (Static and viscous)
• Configurable I/O assignment and scaling for non standard applications
• Similar packages for DC and AC ensure user familiarity
• Comprehensive user manual
• Optional (AC drives only) Fieldbus Interfaces: PROFIBUS-DP, INTERBUS, DeviceNet, Modbus Plus, Modbus, CTNet, CANopen & CAN
