BICO interconnections

Introduction
Each drive unit contains a large number of input and output variables as well as internal control
variables. BICO technology (binector connector technology) allows the drive to be adapted to
a wide variety of conditions.
Digital and analog signals, which can be interconnected as required by means of BICO
parameters, are identified by the prefix BI, BO, CI, or CO in their parameter name. These
parameters are identified accordingly in the parameter list or in the function diagrams:
● Binectors (digital): BI: Binector input, BO: Binector output
● Connectors (analog): CI: Connector input, CO: Connector output
To interconnect two signals, a BICO input parameter (signal sink) must be assigned to the
required BICO output parameter (signal source).
