4.2 Control interfaces

Connecting the PROFIBUS cable to the converter

1. Connect the converter to socket X126 via a PROFIBUS cable with the higher-level control.

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.

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.

Set the address of the PROFIBUS slave.

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.
