IEC 61800-7-1:2015

Overview

IEC 61800-7-1:2015 is an international standard published by the International Electrotechnical Commission (IEC) that defines a generic interface between adjustable speed electrical power drive systems (PDS) and their application control programs. This standard is part of the IEC 61800 series, focusing on adjustable speed electrical power drive systems. Specifically, Part 7-1 establishes a universal interface for power drive systems that is independent of any communication network technology.

The standard facilitates the integration and interoperability of various power drive systems within automation and control environments by defining functional elements, application modes, and drive profiles. IEC 61800-7-1:2015 includes mappings of multiple drive profile types to this generic interface and provides technical updates to enhance compatibility with advanced network technologies.

This document does not cover functional safety requirements, which must be addressed by other relevant standards and regulations.
