Recommended PROFIBUS connectors
We recommend connectors with the following article numbers for connecting the PROFIBUS
cable:
● 6GK1500-0FC10
● 6GK1500-0EA02
Pin assignment at the inverter
For the pin assignment at the inverter refer to Section CU230P-2 DP Control Unit (option
K97) (Page 78).
Communication with the controller even when the supply voltage on the Power Module is
switched off
You must supply the Control Unit with 24 VDC at terminals X9:1,2 on the Power Module if
you wish to maintain communication with the controller even when the line voltage is
switched off.
In the case of short interruptions of the 24 V voltage supply, the inverter may report a fault
without communications with the controller being interrupted.

Configuring communication to the control

To configure communication between the inverter and controller, you generally require the
description file GSD of the inverter.
When STEP 7 and STARTER are installed, you do not need GSD.
