Working with Binary Connectors (BiCo)
10.8.1 Introduction
To make use of BiCo you will need access to the full parameter list. At this level
many new parameter settings are possible, including BiCo functionality. BiCo
functionality is a more flexible way of setting and combining input and output
functions. It can be used in most cases in conjunction with the simple, level 2
settings.

10.8.2
How does BiCo work?
The BiCo system, used on more complex drives such as Masterdrives, allows
complex functions to be programmed. Boolean and mathematical relationships can
be set up between inputs (digital, analogue, serial etc.) and outputs (inverter
current, frequency, analogue output, relays etc.).

The MICROMASTER 411/COMBIMASTER 411 uses a simplified version of BiCo,
(which is still very flexible) contained within the parameter set. The system can be
set up without using additional software or hardware.

Example 1
Use BiCo parameterization to enable the output relay using Digital Input 2.
Step
Action
1
Set P0003 to 3 to access all parameters.
2
Set P0702 to 99 to enable BiCo parameterization on Digital Input 2.
Note:
If P0701, 2, 3, or 4 are set to 99, it is not possible to change them to another value; the
inverter must be reset to factory defaults.

If P0701, 2, 3, or 4 are set to 99, it is not possible to change them to another value; the
inverter must be reset to factory defaults.
3
Because Digital input 2 is ‘open’ to BiCo settings, a new value 722.1 now appears in P0731.
The value 722.1 means ‘connect to digital input 2’
The value 722.1 means ‘connect to digital input 2’
(722.0 = input 1, 722.2 = input 3 etc.).
Set P0731 to 722.1
4
Run the inverter using input 1 and operate the relay using input 2.
NOTE:
BiCo is a ‘reverse’ connection. That is, the output function is connected back to the
input so it is not possible to tell from P0702 (99) what the digital input is controlling.
However, there are many diagnostic parameters that can assist in setting up BiCo
functions. (See following examples).
