SINAMICS S120 CUA31 Control Unit adapte

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 CU320 Control Unit then takes over 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
configuration (Figure 2). This provides maximum flexibility for
the use of SINAMICS S120 units.

SINAMICS S120 CU310 Control Unit

The use of a SINAMICS S120 AC Drive in a single-axis application
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 connecting to the higher-level
control. CU310 DP with a PROFIBUS DP connection or CU310 PN
with an integrated PROFINET interface 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 controller 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 options for drive and higher-level
control.
Drive-related inputs/outputs can be linked via the integrated I/O
interface. An integrated TTL/HTL interface and a DRIVE-CLIQ interface are available as encoder interface. For a version with an
integrated motor this encoder interface features the advantage
of an electronic rating plate.
It is easy to implement safety systems using the currently available integrated safety functions such as “Safe standstill” (STO),
“Safe brake control” (SBC) and “Safe stopping” (SS1).

CUA31/32 Control Unit Adapter for multi-axis applications with SINAMICS S120 AC Drive

The drive is coupled to e. g. a CU320
multi-axis Control Unit through the CU
Adapter CUA31 via a DRIVE-CLiQ interface. In this collection, SINAMICS S120
AC Drives can also be used together with
SINAMICS S120 multi-axis drive units.
This collection provides the highest
degree of flexibility when using
SINAMICS S120 Drives.
When compared to the CUA31, the
CUA32 additionally has an HTL/TTL
encoder interface to connect up an
external encoder.
