CU310-2 Control Units for single-axis drives
■
Integration
The CU310-2 Control Unit controls Power Modules in blocksize
format via the PM-IF interface. DRIVE-CLiQ motors as well as
Sensor Modules (SMC) can 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 chan-
ged directly on the device. The BOP20 Basic Operator Panel
can also be snapped onto the CU310-2 Control Unit during ope-
ration to perform troubleshooting procedures.
The CU310-2 Control Unit and other connected components are
commissioned and diagnosed with the STARTER commissio-
ning tool. The CU310-2 Control Unit requires
a CompactFlash
card with firmware version V4.4 or higher.
A CU310-2 PN Control Unit communicates with the higher-level
control system using PROFINET IO and the PROFIdrive V4 pro-
file.
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 PROFId-
rive 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 V4.4 or higher is essential
for the operation of the CU310-2
Control Unit.
