Legal information
Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Introduction 1
1.1 About this manual
Who requires the operating instructions and what for?
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 install, connect-up, parameterize, and
commission the inverters safely and in the correct manner.
What is described in the operating instructions?
These operating instructions provide a summary of all of the information required to operate
the 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.

1.4 Adapting the inverter in line with the application
1.4.1 General basics
Adapting the inverter to the drive task
By means of commissioning with prompting, the inverter is adapted to the motor and the
drive task so that the motor can be optimally operated and protected.
Functions extending beyond commissioning are activated and adapted by changing
parameters directly.
Both commissioning and the parameterization of functions may be undertaken with one of
the following operating units:
● Keyboard and display unit (Operator Panel) that is snapped onto the inverter.
– BOP-2 Basic Operator Panel-2
– IOP Intelligent Operator Panel
● Software (STARTER commissioning tool) that allows the inverter to be parameterized
and controlled from a PC.
Inverters are especially used to improve and expand the starting and speed response of
motors.
Many standard applications can function with the default parameters set in the factory
Although 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
Commissioning with factory settings (Page 60)).
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.

1.4.2 Parameter
There are two types of parameters, adjustable and display parameters.
Adjustable parameters
Adjustable parameters are preceded with 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.
Change protection for setting 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 automatic
follow-on parameterization.
Example: Use P0922 to define the PROFIdrive telegram that the inverter uses to
communicate with the higher-level control. As follow-on parameterization, P0840 (source
of the ON/OFF1 command), for example, is assigned a permanent protected value
depending on the value of P0922.
For each parameter, the List Manual specifies whether and which conditions apply for
changing the values.
Display parameters
Display parameters are preceded with the letter "r". You cannot change the value of these
parameters.
Example:
r0027 is the parameter for the 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 inverter.
1.4.3 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.)
You will find more information about follow-on parameterization for P0700 in the List Manual.
1.4.4 Parameter changes, which subsequently result in internal calculations
When changing the following parameters, the inverter is busy with internal calculations for
several seconds. During this time, no entries are possible.
● p0014 Buffer mode
● p0340 Calculation of control parameters
● p0970 DO/reset drive
● p0971 DO/save drive
● p1082 Maximum speed
● p3235 Phase failure monitoring time
● p3900 Completion quick commissioning
● p1030 Motorized potentiometer config
● p2230 Tech motorized potentiometer config
● p0918 PROFIBUS address
● p2020 Fieldbus baud rate
● p2021 Fieldbus address
● p2030 Fieldbus selection
● p2042 PROFIBUS ident
● p8620 CAN address
● p0804 Data copy, MMC - flash
● p1900 MotID
This state "busy with internal calculations" is displayed as follows:
● at the BOP-2: "Busy"
● at the IOP: Progress bars
Further, the state can also be read-out using p3996:
● r3996 = 0 Inputs possible
● r3996 > 0 Inverter busy, inputs not possible

Most of the BICO blocks can be parameterized. You can adapt the blocks to your application
using parameters.
You cannot change the signal interconnection within the block. However, the interconnection
between blocks can be changed by interconnecting the inputs of a block with the appropriate
outputs of another block.
The signal interconnection of the blocks is realized, contrary to electric circuitry, not using
cables, but in the software.

Binectors and connectors
Connectors and binectors are used to exchange signals between the individual BICO blocks:
● Connectors are used to interconnect "analog" signals. (e.g. MOP output speed)
● Binectors are used to interconnect "digital" signals. (e.g. 'Enable MOP up' command)
