In summary: An inverter system is a combination of standalone
products and services which create new usable drive
system properties with added value.
1.1.2 System
environment
Analysis of the system environment of inverter drives reveals four inter-
faces which outline that environment:
1. Interface to the processing process
2. Interface to the automation process
3. Interface to the surrounding environment and installation conditions
4. Interface to the requirements arising from standards, regulations and
safety concerns
Figure 1.2 System environment
This section deals with the interface to the “processing process”. The
other interfaces are dealt with in the subsequent sections of the guide.
