SINAMICS S120 drive system
Control Units
CU310-2 Control Units for single-axis drives
■
Integration
The CU310-2 Control Unit drives Power Modules in blocksize
format via the PM-IF interface. DRIVE-CLiQ motors or Sensor
Modules (SMC) can also be connected to the integrated
DRIVE-CLiQ socket to permit the operation of motors without
a DRIVE-CLiQ interface.
With the BOP20 Basic Operator Panel, parameters can be
changed directly on the device. The BOP20 Basic Operator
Panel can also be snapped onto the CU310-2 Control Unit
during operation to perform diagnostics.
The CU310-2 Control Unit and other connected components are
commissioned and diagnosed with the STARTER commissioning
tool. The CU310-2 Control Unit requires
a CompactFlash card with
firmware V4.4 or higher.
A CU310-2 PN Control Unit communicates with the higher-level
control system using PROFINET IO and the PROFIdrive V4
profile.
The SINAMICS S120 drive system with the CU310-2 PN Control
Unit then assumes the function of a PROFINET IO device and
can perform the following functions:
•
PROFINET IO device
•
100 Mbit/s full duplex
•
Supports real-time classes of PROFINET IO:
- RT (Real-Time)
- IRT (Isochronous Real-Time), minimum send cycle 500
µ
s
•
Connects to controls as PROFINET IO devices using
PROFIdrive compliant with Specification V4
•
Standard TCP/IP communication for engineering processes
with the STARTER commissioning tool and for accessing the
integrated web server
•
Integrated 2-port switch with two RJ45 sockets based on the
ERTEC ASIC. The optimum topology (line, star, tree) can there-
fore be configured without additional external switches.
A 24 V supply voltage must be connected to terminal X124 for
the digital outputs to be used. A CompactFlash card with firm-
ware version V4.4 or higher is a mandatory requirement
for
operation of the CU310-2 Control Unit.
