Connecting the PROFINET cable to the inverter
Procedure
To connect the inverter to a control via PROFINET, proceed as follows:
1. Integrate the inverter in the bus system (e.g. ring topology) of the control using PROFINET
cables and the two PROFINET sockets X150-P1 and X150-P2.
The maximum permitted cable length from the previous station and to the next one is 100
m.
2. Externally supply the inverter with 24 VDC through terminals 31 and 32.
The external 24 V supply is only required if communications with the control should also
run when the line voltage is switched off.
You have connected the inverter to the control using PROFINET.
Communication with the controller even when the supply voltage on the Power Module is
switched off
You must supply the Control Unit with 24 V DC at terminals 31 and 32 if you wish to maintain
communication with the control system when the line voltage is switched off.
In the case of brief interruptions of the 24 V power supply, the inverter may signal a fault without
communications with the control system being interrupted.

What do you have to set for communication via PROFINET?
Configuring PROFINET communication
Proceed as follows to configure the PROFINET communication between the IO Controller and
the inverter as IO Device:
1. Configure the IO Controller and the IO Device with an engineering system, e.g. with HW-
Config.
If required, install the GSDML file of the inverter in the engineering system.
2. Load the configuration data into the IO Controller.
Device name
In addition to the MAC address and IP address, PROFINET also uses the device name to
identify PROFINET devices. The device name must be unique across the PROFINET network.
To assign the device name, you need an engineering software, e.g. HW-Config or STARTER.
The inverter saves the device name on the inserted memory card.
IP address
In addition to the device name, PROFINET also uses an IP address.
