Introduction 1
1.1 About this manual
Who requires the Operating Instructions and why?
These Operating Instructions primarily address fitters, commissioning engineers and
machine operators. The Operating Instructions describe the devices and device components
and enable the target groups being addressed to assemble, connect-up, parameterize, and
commission the frequency inverters safely and in the correct manner.
What is described in the Compact Manual?
The Operating Instructions provide a summary of all of the information required to operate
the frequency inverter under normal, safe conditions.
The information provided in the Operating Instructions has been compiled in such a way that
it is sufficient for all standard applications and enables drives to be commissioned as
efficiently as possible. Where it appears useful, additional information for entry level
personnel has been added.
The Operating Instructions also contain information about special applications. Since it is
assumed that readers already have a sound technical knowledge of how to configure and
parameterize these applications, the relevant information is summarized accordingly. This
relates, e.g. to operation with fieldbus systems and safety-related applications.

personnel)

1.2 Adapting the frequency inverter to the particular application (parameter
assignment for entry-level personnel)
1.2.1 General basics
Parameterizable frequency inverters transform standard motors into variable-speed drives
Frequency inverters are parameterized to adapt them to the motor being driven so that this
can be optimally operated and protected. This is realized using one of the following operator
units:
● Keyboard and display unit (Operator Panel) that is snapped onto the frequency inverter.
● Software (STARTER commissioning tool) that allows the frequency inverter to be
parameterized and controlled from a PC.
Frequency inverters are especially used to improve and expand the starting and speed
response of motors.
Many standard applications can function with the default parameters
Although frequency inverters can be parameterized for very specific applications, many
standard applications can be configured by means of just a few parameters.
Use the factory settings (where possible)
For basic applications, commissioning can be carried out using just the factory settings (see
Section "Commissioning with factory settings").
Use quick commissioning (for simple, standard applications)
In the majority of standard applications, commissioning can be carried out by entering or
changing just a few parameters during quick commissioning (see "Section "Commissioning
with Operator Panel").

Operating Instructions, 08.10. 2008, t.b.d. 11
1.2.2 Parameter
Parameter types
There are two types of parameters, adjustable and display parameters.
Adjustable parameters
Adjustable parameters are represented with four digits preceded by the letter "P". You can
change the value of these parameters within a defined range.
Example:
P0305 is the parameter for the rated motor current in Amps. This parameter is set during
commissioning. You can enter values between 0.01 and 10000.
Display parameters
Display parameters are represented with four digits preceded by the letter "r". You cannot
change the value of these parameters.
Example:
r0027 is the parameter for the frequency inverter output current. The inverter measures the
current and writes the current value to the parameter. You can display the parameter value,
e.g. using an analog output of the frequency inverter.
Change protection for write parameters
The process of changing parameter values is subject to certain conditions. If an attempt to
change a parameter is rejected by the inverter, this can have a number of causes:
1. The inverter operating state does not allow you to change parameters.
For example, certain parameters can only be changed when the inverter is in
commissioning mode.
2. In some cases, you may not be able to change certain parameters due to follow-on
parameterization.
When P0701 = 1, for example, the ON/OFF1 command is connected to digital input 0.
P0840 (source of the ON/OFF1 command) is then assigned 722.0 (status of digital input
0) due to follow-on parameterization, which means that P0840 can no longer be changed.
3. Parameter protection via P0927 has been activated.
For example, you can no longer change parameters via the BOP because this has been
blocked (P0927 = 1101).
For each parameter, the List Manual specifies whether and which conditions apply for
changing the values.

1.2.3 Parameters with follow-on parameterization
Parameters with follow-on parameterization
When you change certain parameters, the system may automatically change other
parameters accordingly. This makes it much easier to parameterize complex functions.
Example: Parameter P0700 (command source)
Parameter P0700 can be used to switch the command source from the fieldbus to digital
inputs. When the value of P0700 is changed from 6 (command source "fieldbus") to 2
(command source "digital inputs"), other parameter values are changed automatically:
● New functions are assigned to the digital inputs (P0701 ... P0713)
● New functions are assigned to the digital outputs (P0731 ... P0733)
● Inverter control is interconnected with the signals from the digital inputs (P0800, P0801,
P0840, etc.)
For more information about follow-on parameterization for P0700, see the List Manual.

Figure 1-2 Overview of inverter functions
The functions can be parameterized and interconnected as required. The functions are
interconnected using special software, however, rather than on the basis of electrical circuit
logic by means of cables. The various functions use a range of inputs, outputs, and
parameters.

Frequency inverter
16 Operating Instructions, 08.10. 2008, t.b.d.
Binectors and connectors
Connectors and binectors are elements used to exchange signals between the individual
functions. Connectors and binectors can be seen as "storage compartments":
● Connectors are used to store "analog" signals (e.g. speed setpoint)
● Binectors are used to store "digital" signals (e.g. 'MOP raise' command)
Definition of BICO technology
BICO technology describes the type of parameterization that can be used to disconnect all
the internal signal interconnections between the functions or establish new connections. This
is realized using Binectors and Connectors. hence the name BICO technology.
BICO parameters
You can use the BICO parameters to define the sources of the input signals of a function.
This means that using BICO parameters you can define from which connectors and
binectors a function reads-in its input signals. thereby enabling you to "interconnect" the
functions stored in the devices in accordance with your requirements. Four different BICO
parameter types are available:
● Binector inputs: BI
● Connector inputs: CI
● Binector outputs: BO
● Connector outputs: CO
● Binector/connector outputs: CO/BO
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 feature reduces the number of parameters and makes it easier to
set parameters by means of the serial interface (data transfer).
BICO parameters of type 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 drive in line with 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 setpoint to the analog input.
What precautions should you take when using BICO technology?
Always take care when establishing 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 software contains 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.
What sources of information do you need to help you set parameters using BICO
technology?
● This manual is sufficient for simple interconnections (e.g. assigning a different function to
digital inputs).
● The parameter list in the List Manual is sufficient for more complex interconnections.
● You can also refer to the function diagrams in the List Manual for complex
interconnections.

1.4.2 BICO technology: example
Example: Shifting a basic PLC functionality into the frequency inverter
A conveyor system is to be configured in such a way that it can only start when two signals
are present simultaneously. These could be the following signals, for example:
● The oil pump is running (the required pressure level is not reached, however, until after
five seconds)
● The protective door is closed
The task is realized by inserting free blocks between the digital input 0 and the internal ON
command for the motor and interconnecting them.

Explanations of the example
Open the default signal interconnection for BICO parameterization
The default setting P0701 = 1 indicates the following internal signal interconnection:

P0840 ON/
OFF1
DI 0
Figure 1-5 Default parameterization
The setting P0701 = 99 means that a pre-assigned signal interconnection is disconnected
and therefore the connection opened for BICO parameterization.

Figure 1-6 BICO parameterization
When P0701 = 99, the binector input of the ON/OFF1 function (P0840) is available for
activation by a signal source other than r0722.0 (in this case r2852).

Principle of connecting functions by means of BICO technology
A connection between two functions comprises a connector/binector and a BICO parameter.
Connections are always established with respect to the input of a particular function, which
means that the output of an upstream function must always be assigned to the input of a
downstream function. The assignment is always made by entering the number of the
connector/binector from which the required input signals are read in a BICO parameter.
With this functional logic in mind, where does the signal come from?
