SINAMICS S120 drive system
Introduction
Chassis format
Higher-output units (approximately 100 kW and above) are
constructed in chassis format. These devices are available as
Line Modules and Motor Modules. Chassis format units are
cooled by an internal air cooling circuit.
Blocksize format
The units in blocksize format are optimized for single-axis
applications.
The CU310-2 DP/CU310-2 PN Control Units or CUA31 Control
Unit Adapters can be snapped on directly. The units are cooled
by an internal air cooling circuit.

SINAMICS S120 Combi
SINAMICS S120 Combi is a very compact and rugged drive
system for compact turning and milling machines.
The prerequisite for operation of the SINAMICS S120 Combi is
an NCU 710.3B PN.
SINAMICS S120 Combi integrates a line infeed with regenerative
feedback capability, power units for spindle and feed motors as
well as a TTL encoder interface into a single Power Module.
Special features are the minimum space requirement in the con-
trol cabinet, low energy requirement thanks to state-of-the-art
400-V technology, and perfected expendability using additional
Motor Modules in booksize compact format.
The expansion using Motor Modules in booksize compact
format is only permissible in combination with a NCU 710.3B PN
and the SINAMICS S120 Combi (SINUMERIK 840D sl BASIC).
An intelligent DRIVE-CLiQ interface is provided for cabling.
