3.1.2.3BICO technology

Using BICO technology (English: Binector Connector Technology), process data can be freely interconnected using the "standard" drive parameterization. In this case, all values which can be freely interconnected (e.g. frequency setpoint, frequency actual value, current actual value, etc.) can be defined as "Connectors" and all digital signals which can be freely interconnected (e.g. status of a digital input, ON/OFF, message function when a limit is violated etc.) can be defined as "Binectors".

There are many input and output quantities as well as quantities within the control which can be interconnected in a drive unit. It is possible to adapt the drive to the various requirements using BICO technology.

A binector is a digital (binary) signal without any units and which can either have the value 0 or 1. Binectors always refer to functions whereby they are sub-divided into binector inputs and binector outputs (refer to Fig. 3-4). In this case, the binector input is always designated using a "P" parameter plus attribute "BI" (e.g.: P0731 BI: Function, digital output 1), while the binector output is always represented using an "r" parameter plus attribute "BO" (e.g.: r0751 BO: ADC status word).

As can be seen from the examples above, the binector parameters have the following abbreviations in front of the parameter names:

BI Binector Input, signal receiver ("P" parameters)

→The BI parameter can be interconnected with a binector output as source, by entering the parameter number of the binector output (BO parameter) as value in the BI parameter (e.g.: Interconnecting the "BO" parameter r0751

with "BI" parameter P0731 → P0731 = 751).

BO Binector Output, signal source ("r" parameters)

→The BO parameter can be used as source for BI parameters. For the particular interconnection the BO parameter number must be entered into the BI parameter (e.g.: Interconnecting the "BO" parameter r0751 with "BI"

parameter P0731 →		P0731 = 751).
