Leading Bavarian manufacturer Hans Weber Maschinenfabrik GmbH was looking for drives that could improve the efficiency of its grinding machines, whilst maintaining the renowned high-quality finish given to every product, be it metal or wood.But with limited space in the machine control cabinets, WEBER needed a small solution that could deliver big benefits, and the compact VLT® AutomationDrive FC 302 was the perfect fit.
A wide variety of motor technologies are installed in the grinding machines, from induction to permanent magnet motors, all operated by the same type of drive.
Grinding units need to work with the greatest speed, accuracy, and stability to ensure precision on the grinding surface. WEBER therefore needed low voltage drives that could keep the motor at a constant speed to achieve an optimal grinding pattern.
Up to 13 VLT® drives were installed to control different parts within the grinding machines, such as the sanding unit, position controller, vacuum table, and conveyor belt.
WEBER utilizes Eco Drive technology, where the Danfoss drives automatically recognize the load on the respective grinding unit and regulate optimal processes and ranges of action. This reduces losses in the drive system and enables energy savings of around 15%.
The compact VLT® AutomationDrive FC 302 maximizes available space in the control cabinet as it does not require any additional electrical components, electromagnetic compatibility filters or chokes.
WEBER also benefits from DrivePro® Remote Expert Support, a maintenance service that provides easy, fast and secure access to all drives. In the event that a fault arises, Danfoss can support customers around the world.
Danfoss is committed to providing the highest levels of customer service. A permanent support team made up of application engineers, service technicians, salespeople and back-office employees is available to ensure Hans Weber machines stay up and running at all times.
“We have worked with Danfoss for a long time and the cooperation has always gone well. They know their way around our products and they know us. They understood exactly what we needed and we received drives that were perfectly suited to our requirements. The Danfoss VLT® AutomationDrive FC 302 supports our high-precision grinding machines but most importantly it enables us to reduce energy consumption and operating costs.”
- Stefan Fischer, Head of Electrical Design at Hans Weber
The VLT® AutomationDrive FC 301 / FC 302 is designed for variable speed control of all asynchronous motors and permanent magnet motors. It comes in a standard version (FC 301) and an advanced high dynamic version (FC 302) with additional functionalities.
