KEB F6 drive controllers allow cost-effective upgrade of warehouse storage & retrieval machine
08 March 2021
KEB Automation has helped a customer in Germany to convert its high-bay warehouse storage and retrieval machine from an old-generation frequency inverters to the new COMBIVERT F6 drive controller from KEB.
The warehouse is owned and operated by a mail order business that was looking for a modern, cost-effective retrofit solution that would not require the existing motors to be replaced.
The high-bay warehouse currently comprises nine aisles. Each aisle has 106 positions along its length (on both sides of the aisle) and 28 positions in height (on both sides).
Jorg Buchwald-Hörnchen, PLC Technician at the warehouse, comments: "The main focus was on costs. Of course, other competitors also submitted bids for their products, but the statements from them were always the same: ‘we cannot work with your existing motors’. At KEB, this was not an issue at all from the start. They said it didn’t matter what kind of motor was there, we can run all motors with our COMBIVERT F6."
With the COMBIVERT F6, users can operate KEB’s own motors as well as a variety of other motor types from different manufacturers. "That’s how it turned out. It was very easy to get the existing motors working with the inverters, using automatic calibration. The aim was to replace only the frequency inverters, from the COMBIVERT F4 series to the F6," adds Jorg Buchwald-Hörnchen.
