The document discusses preparations for commissioning a SINAMICS S120 drive system. It includes 5 key steps: 1) Component wiring, 2) Rules for DRIVE-CLiQ wiring, 3) Activating online operation via PROFIBUS, 4) Using the STARTER commissioning tool, and 5) Ensuring the CU320 has the correct CompactFlash card with the necessary firmware and user parameter files. The summaries provide an overview of the commissioning process and essential configuration tasks.

HW-wiring:
SLM X21:1 (DO) >> TB30 X481:1 (DI0)
ALM.p863.0
TB30.r4022.0 = drive_02.p864
drive_03.p864
= drive_02.p864
drive_03.p864
By using a SLM without DRIVE-CLiQ
connection you have to connects and
parameterize the I/O terminals.

is installed.
The communication from the
STARTER to the CU320 takes place
over PROIBUS under observance of
the construction-guidelines.
The PG/PC interface is with the
system-function „PG/PC interface puts
in “, to furnish,
For the CU320 interface, the address is
to be put in merely.

6. Preparation 3: Set PG/PC Interface
Used Interface:
• PG/PC is the only master?
• Test
PROFIBUS
(no PROFIBUS-DP Slave)
• 12 Mbit/s
• DP or User-Defined with
NetPro
• Read Bus Nodes: 0 + 4 + ...
