Until a few years ago, the servo drives and associated power supplies for the typical industrial machine were all installed in air-conditioned, centralized drive cabinets and often required long power runs and feedback cables out to the motors themselves.
On large machines especially, this approach required that a good bit of installation and commissioning work be reserved for the end user's facility, adding onsite troubleshooting effort and start-up time. In this latest installment of the Control Design Essentials series, learn how to cut costs and build more flexible machines with distributed servo systems.
