fitting without keys. The drive systems are highly efficient even in the partial load range and at low speeds, paying for their initial cost within a few years or even only months, and significantly reducing total expenses over the product lifespan. The frequency inverters are configured exactly to Glidepath’s specifications – with plug-in connectors for power, communications, encoders, and sensors. They feature an internal EtherNet/IP interface and are designed for easy feed-through installation. The pluggable drives saved Glidepath a lot of time during installation and commissioning, with the coded connectors ensuring speedy, error-free networking. “Thanks to the field I/O capability of the
NORD drives, we were able to connect the majority of our field devices directly to the frequency inverters,” adds Williams. Featuring industrial Ethernet communications, the drives enable not only remote monitoring and control of all drive axes, but also seamless monitoring of connected sensors and actuators. For Williams, this was a crucial factor: “The real advantage here is the drives support high-speed Ethernet, which allows for reliable bag tracking on our system.” The drive systems take on various tasks at the conveyor modules. They move luggage at different speeds from one belt to the next. They ensure accurate height adjustment when conveying diagonally. Glidepath only came to realize the full
potential of the integrated positioning function of NORDAC FLEX inverters once the drives were commissioned. As they gathered parameters for various applications, NORD engineers soon found that the positioning function was the optimal solution for the luggage sorters. A NORD specialist for their industrial sector provided significant support to Glidepath through efficient standardization. “On this project, we have just five different gear ratios for a job that has 90-odd motors in total and three different motor sizes”, Williams says. “That is a huge advantage. As a consequence, we need only one spare drive per gear type and engine size.”
