1.5.1 BICO technology: basic principles
Functional principle of BICO technology and inverter closed/open-loop control functions
The inverter software offers a range of open/closed-loop control functions, communication
functions, as well as various diagnostics and operating functions. These functions are
interconnected via internal signal paths and represent the default control structure.

Control Unit
The functions can be parameterized and interconnected as required. The signal
interconnection of the functions is realized, contrary to electric circuitry, not using cables, but
in the software. The various functions use a range of inputs, outputs, and parameters.

Binectors and connectors
Connectors and binectors are elements used to exchange signals between the individual
functions. Connectors and binectors can be seen as "storage compartments":
● Connectors are used to store "analog" signals (e.g. speed setpoint)
● Binectors are used to store "digital" signals (e.g. 'MOP raise' command)
Definition of BICO technology
BICO technology describes the type of parameterization that can be used to disconnect all
the internal signal interconnections between the functions or establish new connections. This
is realized using Binectors and Connectors. Hence the name BICO technology. ( Binector
