Introduction 1.6 Extended scope for adaptation Extended scope for adaptation 1.6.1 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.
Page 21 Introduction 1.6 Extended scope for adaptation Definition of BICO technology BICO technology represents a type of parameterization that can be used to disconnect all internal signal interconnections between BICO blocks or establish new connections. This is realized using Binectors and Connectors. Hence the name BICO technology. ( Binector Connector Technology) BICO parameters You can use the BICO parameters to define the sources of the input signals of a block.
