Power section for driving an electric drive, a drive control based thereon, and a method for networking a control unit with one or more power sections
First Claim
1. A method for networking a control unit of a drive control with at least one power section of the drive control, comprising connecting the control unit of the drive control to at least one power section of the drive control, through a digital interface with real-time capability, the at least one power section including computing capacity, and synchronizing the communication between the control unit and each of the at least one power section by means of a digital transmission protocol.

Abstract
By distributing the intelligence of a drive between a control unit and one or more intelligent power sections by using a high-power standardized serial interface for connecting these components, it is possible as a result to identify different power components with their performance data, and also to diagnose them. Furthermore, independent innovations of the components are possible without having corresponding effects on the other components.
