Signal Interconnection - Siemens SINUMERIK 840D sl Manual

Signal Interconnection

Introduction
The ACX macros assign functions to the NCU and NX terminals (see the "NCU/NX Terminal
Assignment" section).
This section discusses the interconnection of the terminals between the SINUMERIK and
SINAMICS S120 components.
The used terminals must be controlled from a higher-level controller or PLC. For safety
functions, the NCU and NX or the Motor Modules must be controlled in accordance with the
required safety categories (see the "Safety Integrated" section).
For the applications
The following pages show the signal interconnection for typical SINUMERIK /
SINAMICS S120 applications.
The following table shows the characteristics of the individual applications. The listed
applications show only a few possiblities. If necessary, the control must be adapted to the
requirements of the associated application.
