Integrating inverters into PROFIBUS

To connect the inverter to a control system via PROFIBUS DP, proceed as follows:
Procedure
1. Integrate the inverter into the bus system (e.g. line-type topology) using PROFIBUS
cables.
– Inverters with IP20 degree of protection: via socket X126
– Inverters with degree of protection IP65 (CU240D/CU250D) via X03 and X04
The position of the socket is explained in the operating instructions for the inverter.
Pin assignment:
The maximum permitted cable length to the previous station and the subsequent one is
100 m at a baud rate of 12 Mbit/s. You can achieve a maximum cable length of 400 m by
using a maximum of 3 repeaters.
2. Externally supply the inverter with 24 V DC through terminals 31 and 32 or via X01.
The external 24 V supply is only required if communications with the control system
should also operate when the line voltage is switched off.
You have now connected the inverter to the control system using PROFIBUS DP.

Configuring communication to the control system

Configure the communication in the control system after you have connected the inverter to
the bus.
3.7.4.1

Configuring the communication using SIMATIC S7 control

● If the inverter is listed in the component catalog in the TIA Portal, you can configure the
communication in the SIMATIC control.
● If the inverter is not listed in the hardware library, you can either install the newest
Startdrive version or install the GSD of the inverter via "Extras/GSD-Install file" in HW-
Config.
3.7.4.2

Configuring the communication with a third-party control system

If you are working with a third-party control system, you must install the device file (GSD) of
the inverter in the control before you configure the communication.
If you have installed the GSD, configure the communication. To do this, follow the
documentation of your control system.
