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.
