4. Connect the output terminal ”DO 8” (X122.7) of Control_Unit_1 to the input
terminal ”DI 0” (X122.1) of Control_Unit_2 via an external interconnection.
5. The output terminal of Control_Unit_1 must be wired to an input terminal of
Control_Unit_2.
6. Via BICO interconnection, the input terminal of Control_Unit_2 must be inter-
connected to the drive parameters ”p864, BI: Infeed operation” of all Con-
trol_Unit_2 drives.
7. There is no DRIVE CliQ connection between the infeed and Control_Unit_2.
