Gram Equipment uses Allen-Bradley PowerFlex and Kinetix servo drives communicating via Ethernet/IP and DeviceNet with frequency transformers, controllers, I/O modules控制工程网版权所有, and HMI systems.
with mixing equipment and packaging lines. With more customers looking for increasingly advanced solutions, new installations now typically require increasing production speed, new levels of complexity, and many specialized functions. As an example, Gram Equipment is currently constructing a very large production line that will be able to produce 36,000 units per hour. Of course, every element in the system must work reliably and with a minimum of down time.
From many solutions to one
Before implementing Rockwell Automation’s Safety solution two years agowww.cechina.cn, Gram often experienced problems with traditional safety systems, typically comprising a PLC, a separate safety PLC, and a servo system. Operators and maintenance staff had to learn how to use three different software programs, including how to connect the systems so they could communicate with
