Variable speed drives help improve machine productivity

11 August 2015

Render Technology, an Italian manufacturer of end-of-line handling and palletising machines for the packaging market, has aligned itself with Emerson’s Control Techniques for drives. 

The business is said to have had seen productivity of its machines increase by 20% as a result of using Unidrive M variable speed drives. 

Before the implementation of Unidrive M, the machines were able to deliver 25 or 26 cycles per minute. However, since the adoption of Unidrive M, the business has seen returns of up to 30 cycles per minute.  

This increase in productivity means that the palletiser is more valuable to the end customer, allowing Render to command a higher price for its products.  

Previously used drives had delivered the 26 cycles per minute.  While this was adequate at the time the team want to find a drive that could help increase this rate. The precise control offered by Unidrive M was said to be key to enabling Render Technology to engineer a machine able to deliver more cycles per minute.  

Specifically, the M701 drives are deployed for axis position control, with the M700 drives used to control the position and orientation of a smart belt. Movement is undertaken using an electronic cam.

The Unidrive M family of drives offers induction and permanent magnet servo motor performance, with real-time Ethernet. Each drive delivers maximum machine throughput through advanced control algorithms with single and multi-axis network synchronisation.
