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.
Using BICO parameters you define from which connectors and binectors a block reads-in its
input signals. This is how you "interconnect" the blocks stored in the devices according to
your particular application requirements. The five different BICO parameter types are shown
in the following diagram:
Figure 2-3
Binector/connector outputs (CO/BO) are parameters that combine more than one binector
output in a single word (e.g. r0052 CO/BO: status word 1). Each bit in the word represents a
digital (binary) signal. This summary reduces the number of parameters and simplifies
parameter assignment.
BICO outputs (CO, BO, or CO/BO) can be used more than once.
When do you need to use BICO technology?
BICO technology allows you to adapt the inverter to a wide range of different requirements.
This does not necessarily have to involve highly complex functions.
Example 1: Assign a different function to a digital input.
Example 2: Switch the speed setpoint from the fixed speed to the analog input.
What precautions should you take when using BICO technology?
Always apply caution when handling internal interconnections. Note which changes you
make as you go along since the process of analyzing them later can be quite difficult.
The STARTER commissioning tool offers various screens that make it much easier for you
to use BICO technology. The signals that you can interconnect are displayed in plain text,
which means that you do not need any prior knowledge of BICO technology.
