Improve Mining Excavators and More With These System Upgrades
DCS strives to improve the safety, efficiency, production, and uptime of mine excavators as well as other components and facilities related to mining and industry. This has traditionally been the pinnacle of DCS' work as it kept up with advancements in control and drive technology.
In hundreds of instances, DCS has replaced hard-wired relay logic systems with PLCs and replaced deprecated DC field supplies with modern digital drives. We implement a multifaceted approach to our goals, which now involves the integration of many system components and technologies, and we do so while adopting a wide variety of products and manufacturers. Furthermore, we continue to build advanced platforms that enable unprecedented historical monitoring of excavator production, analysis of machine operation, and simplified viewing and adjustment of the control systems.
Siemens DC Digital Drives
These are installed in place of a wide variety of existing, obsolete technologies, from rotating amplidyne packages to DC exciter sets all the way to the predecessors of today's generation of DC drives. The newest Siemens drives, the "6RA80s," have now been utilized in over a dozen excavator upgrades...well over 50 drives in all. Also, the newest drives all contain one standardized, proven, and consistent program that works in all applications.
Several features were introduced with the 6RA80 drives that allow for better communications and control between the drives and PLC. In particular, it is now easier to tune the drives through an interface with the PLC. The 6RA80 drives also store their memory in an SD card, which makes replacing a drive that has been lost to a lightning strike or water damage much easier.
