SINAMICS S120 AC Drive
CU310 Control Unit
The use of SINAMICS S120 AC Drives in single-axis applica-
tions connected to a higher-level control is illustrated in
Figure 1. Each of the AC Drives is equipped with a CU310
Control Unit. This unit contains the field bus interface for con-
necting to the higher-level control. CU310 DP with a PROFIBUS
DP connection or CU310 PN with an integrated Profinet inter-
face can be selected. In both cases communication between
the control and the drive takes place in accordance with the
standardized PROFIdrive profile.
CU310 offers functions ranging from the simple speed con-
troller to full positioning functionality.
Drive-related inputs/outputs can easily be linked in the CU by
means of BICO technology. This permits the greatest possible
separation of drive and higher-level control.
Various types of drive-related inputs/outputs and encoders are
connected easily via the DRIVE-CLiQ interface.
It is easy to implement safety systems using integrated safety
functions such as "Safe standstill" (SH) and "Safe brake con-
trol" (SBC).
CUA31 Control Unit adapter
It is also possible to use SINAMICS S120 AC Drives in multi-axis
applications. The drive is connected to a CU320 Control Unit
via the DRIVE-CliQ interface using the CUA31 Control Unit
adapter. The Control Unit then takes over control of the drive
functions for the AC drive. SIMOTION D modules can be used
as a Control Unit for motion control applications which go
beyond the scope of positioning tasks.
SINAMICS S120 AC Drives can also be used in hybrid operation
with SINAMICS S120 multi-axis units in this constellation. This
provides maximum flexibility for the use of SINAMICS S120
units.

Standardized, comfortable engineering
with SIZER and STARTER
As with all SINAMICS drives, the SIZER configuring tool helps
you to select the optimal drive configuration for your applica-
tion. Graphical support and wizards efficiently guide you
through the selection of necessary components based on your
application.
SINAMICS S120 AC Drives are commissioned using STARTER,
the commissioning tool for the SINAMICS family. Electronic
rating plates ensure automatic and error-free preconfigura-
tion of the drive system. Automatic optimization is a simple
way of optimizing the control response. It ensures fast and
reliable commissioning of the drives.
SINAMICS S120 Power Modules
The frame size of the Power Modules depends on the power
output.
We differentiate between block size and chassis units, which
are available in various frame sizes.
