Inverter with CU240B-2 and CU240E-2 Control Units
106 Operating Instructions, 07/2010, FW 4.3.2, A5E02299792B AA
What prior knowledge is required?
In this example, it is assumed that readers know now to basically use an S7 control and the
STEP 7 engineering tool and is not part of this description.
6.3.1.2 Required components
The examples given in this manual for configuring communication between the control and
inverter are based on the hardware listed below:
Table 6- 2 Hardware components (example)

SINAMICS G120 Power Module Any - 1
PROFIBUS connector PROFIBUS connector 6GK1500-0FC00 1
In order to configure communication you also require the following software packages:
Table 6- 3 Software components
Component Type (or higher) Order no. Qty
SIMATIC STEP 7 V5.3 + SP3 6ES7810-4CC07-0YA5 1
STARTER V4.1 SP5 6SL3072-0AA00-0AG0 1
Drive ES Basic V5.4 6SW1700-5JA00-4AA0 1
Drive ES Basic is the basic software of the engineering system, which combines the drive
technology and Siemens controllers. The STEP 7 Manager user interface acts as a basis
with which Drive ES Basic is used to integrate drives in the automation environment with
respect to communication, configuration, and data storage.
