White Paper: Decentralized Control FAQs, from SEW Eurodrive

Answers to frequently asked decentralized control questions from SEW-Eurodrive, a leading manufacturer of integrated power transmission and motion control solutions.

WHAT IS DECENTRALIZED CONTROL?
 
Q. How is control decentralized?
 
A. In a decentralized control system, motor control functions are removed from a central control cabinet and distributed out on a machine, so that control devices are located closer to the machine’s motors.
 
Q. Is there more than one way to decentralize control?
 
A. There are many levels of decentralization, from a motor starter or drive located at the motor to a fully decentralized system with a variable frequency drive, overload protection, motor disconnect switch, I/O and bus module, all combined in a single package that is installed on or near the motor. This package is often called a field distributor.
