Establishing communication
• To establish communication, the inverter drive must be supplied with mains voltage.
• AS-i communication requires voltage supply of the communication unit.
If this is requirement is not met, the "CE04: MCI communication error" error message (error No.
01.0127.00002) is output. The error must be reset in the Inverter Drive, so that AS-i
communication can be established.
• The Voltage supply

via the AS-i bus cable serves to maintain the AS-i communication in
case of a main supply failure.
• During mains connection, all parameters (codes) are read.
• Addressing can be carried out automatically via the master, an external addressing unit or
manually via codes in the »Engineer«.
