Connecting the PROFIBUS cable to the converter
Procedure
1. Connect the converter to socket X126 via a PROFIBUS cable with the higher-level control.
Overview of the interfaces (Page 99)
The maximum permitted cable length to the previous station or the subsequent one is 100 m
at a baud rate of 12 Mbit/s.
Recommended PROFIBUS connectors:
– 6GK1500-0FC10
– 6KG1500-0EA02
2. If necessary, connect a 24 V supply voltage to terminals 31 and 32.
The external 24 V supply is only required if communication with the control may not be
interrupted even if the line voltage is switched off.
You connected the converter with the control via PROFIBUS.

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 converter into the engineering system.
Setting the address
Set the address of the PROFIBUS slave.
Setting the address (Page 206)
Setting the telegram
Set the same telegram in the converter as in the PROFIBUS master. Interconnect the
telegrams in the control program of the PROFIBUS master with the signals of your choosing.
Drive control via PROFINET or PROFIBUS (Page 206)
