4.5.12.1
Connecting the PROFIBUS cable to the inverter
Procedure
1. Integrate the inverter into the bus system (e.g. line topology) of the control using PROFIBUS
cables via socket X126.
The maximum permitted cable length to the previous station and the subsequent one is
100 m at a baud rate of 12 Mbit/s.
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 now connected the inverter to the control system using PROFIBUS DP.

What do you have to set for communication via PROFIBUS?
Configuring PROFIBUS communication
You require the appropriate engineering system to configure PROFIBUS communication in
the PROFIBUS master.
If required, load the GSD file of the inverter into the engineering system.
Setting the address
Set the address of the PROFIBUS slave.
Setting the telegram
Set the telegram in the inverter as in the PROFIBUS master. Interconnect the telegrams in the
control program of the PROFIBUS master with the signals of your choosing.
