BICO technology: basic principles
Principle of operation of BICO technology
Open/closed-loop control functions, communication functions as well as diagnostic and
operator functions are implemented in the inverter. Every function comprises one or several
BICO blocks that are interconnected with one another.

Example of a BICO block: Motorized potentiometer (MOP)
Most of the BICO blocks can be parameterized. You can adapt the blocks to your application
using parameters.
You cannot change the signal interconnection within the block. However, the interconnection
between blocks can be changed by interconnecting the inputs of a block with the appropriate
outputs of another block.
The signal interconnection of the blocks is realized, contrary to electric circuitry, not using
cables, but in the software.

Binectors and connectors
Connectors and binectors are used to exchange signals between the individual BICO blocks:
● Connectors are used to interconnect "analog" signals. (e.g. MOP output speed)
● Binectors are used to interconnect "digital" signals. (e.g. 'Enable MOP up' command)
