SED2 Operation & Maintenance Manual Addendum

Chapter 4 - BiCo (Binector and
Connector) Data Set Functions
Introduction
The SED2 provides user access levels, set by parameter P0003. User access level 1 gives
access to the most frequently used parameters. User access level 2 gives access to more
advanced parameters. For example, P0701 sets the function of Digital Input 1 with possible
values such as:
1=ON right
12=Reverse
15=Fixed frequency, etc .
User access level 3 gives full access to all other parameters. (User access level 4 is for service
only.)
To make use of BiCo, use access level 3 with full access to the parameters. This is detailed in the
Operations & Maintenance manual. At this level, many new parameter settings are possible,
including BiCo functionality. BiCo functionality is a different k more flexible way of setting and
combining input and output functions. It can be used (in most cases) with the simple access level
2 parameter settings.
How does BiCo work?
The BiCo system is used on more complex drives such as SED2 and allows complex functions to
be programmed so that, for example, Boolean and mathematical relationships can be set up
between inputs (digital, analog, serial, etc.) and outputs (inverter current, frequency, analog
output, relays, etc.).
The SED2 uses a simplified version of BiCo, which is flexible and can be set up without using
additional software or hardware.
Example 1:
Use BiCo parameterization to enable the output relay using digital input 2.
1. Set P0003=3 to access all parameters.
2. Enable BiCo parameterization on digital input 2 by setting P0702=99.
NOTE: If P0701, P0702, P0703 or P0704 are set to 99, it is not possible to change them
to another value and the drive must be reset to factory defaults.
3. Since digital input 2 is "open" to BiCo settings, a new value of 722.1 now appears in P0731.
The value 722.1 means "connect to digital input 2" (722.0 = connect to digital input 1, 722.2 =
connect to digital input 3, etc.). Set P0731 to 722.1.
