Establishing communication
• To establish communication, the inverter drive must be supplied with mains voltage.
• For EtherNet/IP communication, the Communication Unit has to be supplied with voltage.
If this is not the case, the error message "CE04: MCI communication error" (error no.
01.0127.00002) is output. The error has to be reset in the Inverter Drive in order that the
EtherNet/IP communication can be established.
• The external voltage supply serves to maintain EtherNet/IP communication if the main supply
fails.

• During mains connection, all parameters (codes) are read.
• Addressing the inverter requires a valid IP configuration if communication between the PC/
»Engineer« and the inverter via EtherNet/IP is to be established.
