Establishing communication
• To establish a communication, the Inverter Drive must be supplied with mains voltage.
• For AS-i 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 Voltage supply
( 23) 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«.
