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.

Adapting inverter to application
1.3.1
General basics
Inverters are used to improve and extend the starting and speed response of motors.
Adapting the inverter to the drive task
The inverter must match the motor that it is controlling and the drive task to be able to
optimally operate and protect the motor.
Although the inverter can be parameterized for very specific applications, many standard
applications function satisfactorily with just a few adaptations.
Use the factory settings (where possible)
In simple applications, the inverter already functions with its factory settings.
Only basic commissioning is required ... for simple, standard applications
Most standard applications function after just a few adaptations made during the basic
commissioning.
1.3.2
Parameter
Parameters are the interface between the firmware of the inverter and the commissioning
tool, e.g. an operator panel.
Adjustable parameters
Adjustable parameters are the "adjusting screws" with which you adapt the inverter to its
particular application. If you change the value of an adjustable parameter, then the inverter
behavior also changes.
Adjustable parameters are shown with a "p" as prefix, e.g. p1082 is the parameter for the
maximum motor speed.
Display parameters
Display parameters allow internal measured quantities of the inverter and the motor to be
read.
Display parameters are shown with a "r" as prefix, e.g. p0027 is the parameter for the
inverter output current.

BICO technology: basic principles
Principle of operation of BICO technology
Open/closed-loop control functions, communication functions as well as diagnostic and

Example of a BICO block: Motorized potentiometer (MOP)
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)

Introduction
1.5 Extended scope for adaptation
Definition of BICO technology
BICO technology represents a type of parameterization that can be used to disconnect all
internal signal interconnections between BICO blocks or establish new connections. This is
realized using Binectors and Connectors. Hence the name BICO technology. ( Binector
Connector Technology)
BICO parameters
You can use the BICO parameters to define the sources of the input signals of a block.
Using BICO parameters you define from which connectors and binectors a block reads-in its
input signals. This is how you "interconnect" the blocks stored in the devices according to
your particular application requirements. The five different BICO parameter types are shown
in the following diagram:

BICO symbols
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 summary reduces the number of parameters and simplifies
parameter assignment.
BICO outputs (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 inverter to 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 speed to the analog input.
What precautions should you take when using BICO technology?
Always apply caution when handling 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 tool offers 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.

Introduction
1.5 Extended scope for adaptation
What sources of information do you need to help you set parameters using BICO
technology?
● This manual is sufficient for simple signal interconnections, e.g. assigning a different
significance to the to digital inputs.
● The parameter list in the List Manual is sufficient for signal interconnections that go
beyond just simple ones.
● You can also refer to the function diagrams in the List Manual for complex signal
interconnections.

BICO technology: example
Example: Shifting a basic PLC functionality into the converter
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/OFF1 command and interconnecting them.

the second input of the logic block. The logic block output issues the ON/OFF1 command to
switch-on the motor.

Principle when connecting BICO blocks using BICO technology
An interconnection between two BICO blocks comprises a connector or binector and a BICO
parameter. The interconnection is always established from the perspective of the input of a
particular BICO block. This means that the output of an upstream block must always be
assigned to the input of a downstream block. 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.
This interconnection logic involves the question: where does the signal come from?

Connections for PM230, PM240 and PM250 Power Modules
PM240 and PM250 Power Modules are available with and without integrated class A line
filters. Either a Class A or a Class B filter is integrated in the PM230 Power Module.
An external filter has to be installed in PM240 and PM250 Power Modules to satisfy more
stringent EMC requirements (Class B).

Connecting the line supply and motor
Preconditions
Once the inverter has been properly installed, the line and motor connections can now be
established. The following warning information must be observed here.
WARNING
Line and motor connections
The inverter must be grounded on the line supply and motor side. If the inverter is not
correctly grounded, this can lead to extremely hazardous conditions which, under certain
circumstances, can result in death.
The device must be disconnected from the electrical power supply before any connections
with the device are established or in any way altered.
The inverter terminals be at hazardous voltages even after the inverter has been switched
off. After disconnecting the line supply, wait at least 5 minutes until the device has
discharged itself. Only then, carry out any installation and mounting work.
When connecting the inverter to the line supply, ensure that the motor terminal box is
closed.
Even if the LED or other indicators do not light up or remain inactive when a function is
switched from ON to OFF, this does not necessarily mean that the unit has been switched
off or is de-energized.
The short-circuit ratio of the power supply must be at least 100.
Make sure that the inverter is configured for the correct supply voltage (the inverter must
not be connected to a higher supply voltage).
If a residual-current circuit breaker is installed on the supply side of the electronic devices
to protect against direct or indirect contact, only type B is permissible. In all other cases,
other protective measures must be implemented, such as creating a barrier between the
electronic devices and the environment by means of double or reinforced insulation or
isolating them from the supply using a transformer.
CAUTION
Supply cable and signal lines
The signal lines must be routed separately from the supply cables to ensure that the
system is not affected by inductive or capacitive interference.

Note
Electrical protective equipment
Ensure that the appropriate circuit breakers / fuses for the inverter's rated current are fitted
between the line and inverter (see catalog D11.1).

Examples for operating the inverter and motor on a 400 V line supply
Assumption: The motor rating plate states 230/400 V Δ/Y.
Example 1: A motor is normally operated between standstill and its rated speed (i.e. a speed
corresponding to the line frequency). In this case, you need to connect the motor in Y.
Operating the motor above its rated speed is only possible in field weakening, i.e. the motor
torque available is reduced above the rated speed.
Example 2: If you want to operate the motor with the "87 Hz characteristic", you need to
connect the motor in Δ.
With the 87 Hz characteristic, the motor's power output increases. The 87 Hz characteristic
is mainly used with geared motors.

Connecting the inverter
Motor connection
● If available, open the terminal covers of the inverter.
● Connect the motor to terminals U2, V2 and W2.
Carefully observe the regulations for EMC-compliant wiring:
EMC-compliant connection (Page 39)
EMC-compliant installation for devices with degree of protection IP55 / UL Type 12
(Page 42)
● Connect the protective conductor of the motor to the terminal
The following cable lengths are permissible:
of the inverter.
– Unshielded 100 m
– Shielded:
50 m for inverters without filter
25 m for inverters with filter
You will wind additional information in Catalog D11.1 for longer cable lengths
Line supply connection
● Connect the line supply to terminals U1/L1, V1/L2 and W1/L3.
● Connect the protective conductor of the line supply to terminal PE of the inverter.
● If available, close the terminal covers of the inverter.
Note
Inverters without an integrated line filter can be connected to grounded (TN, TT) and nongrounded (IT) line supply systems. The inverters with integrated line filter are suitable
only for connection to TN line supply systems.
The permissible cable cross sections for the individual devices and power ratings are
provided in Section Technical data (Page 303).

3.3.4
EMC-compliant connection
The inverters are designed for operation in industrial environments where high values of
electromagnetic interference are expected. Safe, reliable and disturbance-free operation is
only guaranteed if the devices are professionally installed.
Inverters with degree of protection IP20 must be installed and operated in an enclosed
control cabinet.
Control cabinet design
● All metal parts and components of the control cabinet (side panels, rear panels, roof and
base plates) must be connected to the control cabinet frame through a good electrical
connection – this is best achieved using the highest possible surface area or a high
number of individual screw connections
● The PE bar and the EMC shield bar must be connected to the control cabinet frame
through a good electrical connection established through a large surface area.
● All of the metal enclosures of the devices and supplementary components installed in the
cabinet – e.g. inverter or line filter – must be connected to the control cabinet frame
through a good electrical connection through the largest possible surface area. The most
favorable design is to mount these devices and supplementary components on a bare
metal mounting plate with good conducting characteristics; this in turn is connected to the
control cabinet frame through a good electrical connection and the largest possible
surface area. It is especially important that they are connected to the PE and EMC shield
bars.
● All of the connections must be implemented so that they are durable. Screw connections
to painted or anodized metal components must either be established using special
contact (serrated) washers that cut through the insulating surface and therefore establish
a metallic conductor contact, or the insulating surface must be removed at the contact
locations.
● Coils of contactors, relays, solenoid valves and motor holding brakes must be equipped
with interference suppression elements in order to dampen high-frequency radiation
when switching-off (RC elements or varistors with AC coils and free-wheeling diodes or
varistors for DC coils). The protective circuit must be directly connected at the coil.
Cable routing and shielding
● All inverter power cables (line supply cables, connecting cables between the braking
chopper and the associated braking resistance as well as the motor cables) must be
separately routed away from signal and data cables. The minimum clearance should be
approx. 25 cm. As an alternative, the decoupling can be realized in the control cabinet
using metal partitions (separating elements) connected to the mounting plate through a
good electrical connection
● The cables from the line supply to the line filter must be routed separately away from nonfiltered power cables with a high noise level (cables between the line filter and inverter,
connecting cables between the braking chopper and the associated braking resistor as
well as motor cables)
● Signal and data cables as well as filtered line supply cables may only cross non-filtered
power cables at right angles
● All cables should be kept as short as possible

Installing
3.3 Installing Power Module
● Signal and data cables and the associated equipotential bonding cables must always be
routed in parallel with the smallest possible clearance between them
● Shielded motor cables must be used
● The shielded motor cable should be routed separately away from the cables to the motor
temperature sensors (PTC/KTY)
● Signal and data cables must be shielded.
● Especially sensitive control cables - such as setpoint and actual value cables - should be
routed without any interruption with optimum shield support at both ends
● Shields should be connected at both ends to the grounded enclosures through a good
electrical connection and through a large surface area
● Cable shields should be connected as close as possible to where the cable enters the
cabinet
● EMC shield bars should be used for power cables; the shield support elements provided
in the inverter should be used for signal and data cables
● If at all possible, cable shields should not be interrupted by intermediate terminals
● Cable shields should be retained both for power cables as well as for signal and data
cables using the appropriate EMC clamps. The shield clamps must connect the shield to
the EMC shield bar or the shield support element for control cables through a low
inductive connection through a large surface area.

Shielding with shield plate:
Shield connection kits are available for all Power
Module frame sizes (you will find more information in
Catalog D11.1). The cable shields must be
connected to the shield plate through the greatest
possible surface area using shield clamps.
Shielding without shield plate:
EMC-compliant shielding can also be implemented
without an optional shield plate. In this case, you
must ensure that the cable shields are connected to
the ground potential through the largest possible
surface area.
Braking resistor connection:
The braking resistor is connected using a shielded
cable. Using a clamp, the shield should be
connected to the mounting plate or to the shield
plate through a good electrical connection and
through the largest possible surface area.
EMC-compliant installation for devices with degree of protection IP55 /
UL Type 12
Inverters with degree of protection IP55 / UL Type 12 (Power Module PM230) can be
installed and operated in a closed control cabinet as well as without a control cabinet.
Cable routing and shielding
● Line supply cable and motor cable of the inverter should be routed separately away from
signal and data cables. The minimum clearance should be approx. 25 cm
● All cables should be kept as short as possible
● Signal and data cables and the associated equipotential bonding cables must always be
routed in parallel with the smallest possible clearance between them
● Shielded motor cables must be used
● The shielded motor cable should be routed separately away from the cables to the motor

● If at all possible, cable shields should not be interrupted by intermediate terminals
● Cable shields should be retained both for power cables as well as for signal and data
cables using the appropriate EMC clamps. The shield clamps must connect the shield to
the shield support of the inverter through the largest possible surface area and through a
low inductive connection
● Only metallic or metallized connector enclosures must be used for plug connectors for
shielded data cables (e.g. PROFIBUS cables)

Wiring terminal strips
Solid or flexible cables are permitted as signal lines. Wire end ferrules must not be used for
the spring-loaded terminals.
The permissible cable cross-section ranges between 0.5 mm² (21 AWG) and 1.5 mm² (16
AWG). When completely connecting-up the unit, we recommend cables with a cross-section
of 1mm² (18 AWG).
Route the signal lines so that you can again completely close the front doors after
connecting-up the terminal strip. If you use shielded cables, then you must connect the
shield to the mounting plate of the control cabinet or with the shield support of the inverter
through a good electrical connection and a large surface area.
NOTICE
To ensure operating safety even when connecting 230 V to the Control Unit relay outputs
DO 0 and DO 2, for these connections cables with double insulation must be used.

Restoring the factory setting
There are cases where something goes wrong when commissioning a drive system e.g.:
● The line voltage was interrupted during commissioning and you were not able to
complete commissioning.
● You got confused when setting the parameters and you can no longer understand the
individual settings that you made.
● You don't know whether the inverter was already operational
In cases such as these, reset the inverter to the factory settings.
Restoring the factory setting with STARTER or BOP-2
This function resets the settings in the inverter to the factory settings.
Note
The communication settings and the settings of the motor standard (IEC/NEMA) are retained
even after restoring the factory setting.

4.2.2
Defining requirements for the application
What type of control is needed for the application? [P1300]
A distinction is made between V/f open-loop control and vector closed-loop control.
● The V/f open-loop control is the simplest operating mode for an inverter. For example, it
is used for applications involving pumps, fans or motors with belt drives.
● For closed-loop vector control, the speed deviations between the setpoint and actual
value are less than for V/f open-loop control; further, it is possible to specify a torque. It is
suitable for applications such as winders, hoisting equipment or special conveyor drives.
What speed limits should be set? (Minimum and maximum speed)
The minimum and maximum speed with which the motor operates or is limited regardless of
the speed setpoint.
● Minimum speed [P1080] - factory setting 0 [rpm]
● Maximum speed [P1082] - factory setting 1500 [rpm]
What motor ramp-up time and ramp-down time are needed for the application?
The ramp-up and ramp-down time define the maximum motor acceleration when the speed
setpoint changes. The ramp-up and ramp-down time is the time between motor standstill and
the maximum speed, or between the maximum speed and motor standstill.
● Ramp-up time [P1120] - factory setting 10 s
● Ramp-down time [P1121] - factory setting 10 s

Commissioning with factory settings
Prerequisites for using the factory settings
In simple applications, commissioning can be carried out just using the factory settings.
Check which factory settings can be used and which functions need to be changed. During
this check you will probably find that the factory settings only require slight adjustment:
1. The inverter and motor must match one another; compare the data on the motor rating
plate with the technical data of the Power Module.
– The rated inverter current must, as a minimum, be the same as the motor.
– The motor power should match that of the inverter; motors can be operated in the
power range from 25 % … 100 % of the inverter power rating.
2. If you are controlling the drive using the digital and analog inputs, the inverter must be
connected as shown in the wiring example. (see Wiring examples for the factory settings
(Page 61) )
3. If you connect the drive to a fieldbus, you must set the bus address using the DIP
switches on the front of the Control Unit.

Making additional settings
After the basic commissioning, you can adapt the inverter to your application as described in
the Commissioning (Page 53).
STARTER offers two options:
1. Change the settings using the appropriate screen forms - our recommendation.
① Navigation bar: For each inverter function, select the corresponding screen form.
② tabs: Switch between screen forms.
If you change the settings using screen forms you do not need to know the parameter
numbers.
2. You change the settings using the parameters in the expert list.
If you wish to change the settings using the expert list, you need to know the
corresponding parameter number and its significance.
Saving settings so that they are not lost when the power fails
All of the changes that you make are temporarily saved in the inverter and are lost the next
time the power supply is switched off. For your changes to be permanently saved in the
button (RAM to ROM). Before you press
inverter, you must save the changes using the
the button, you need to mark the appropriate drive in the project navigator.
Go offline
You can now exit the online connection after the data backup (RAM to ROM) with
"Disconnect from target system".

Trace function for optimizing the drive
Description
The trace function is used for converter diagnostics and helps to optimize the behavior of the
drive. Start the function in the navigation bar using "... Control_Unit/Commissioning/Device
trace".
In two settings that are independent of one another, using you can interconnect eight
signals each. Each signal that you interconnect is active as standard
You can start a measurement as often as required; the results are temporarily stored (until
you exit STARTER) under the "Measurements" tab, together with the date and time. When
terminating STARTER or under the "Measurements" tab, you can save the measurement
results in the *.trc format.
If you require more than two settings for your measurements, you can either save the
individual traces in the project or export them in the *.clg format – and if necessary, load or
import.
Recording
Recording is performed in a CU-dependent basic clock cycle. The maximum recording
duration depends on the number of recorded signals and the trace clock cycle.
You can extend the recording duration by increasing the trace clock cycle by multiplying with
an integer factor and then accepting the displayed maximum duration by . Alternatively,
you can also specify the measurement period and then you can calculate the trace clock
cycle of STARTER using .
Recording individual bits for bit parameters
You can record individual bits of a parameter (e.g. r0722) by allocating the relevant bit using
"bit track" ( ).
Mathematical function
Using the mathematical function ( ) you can define a curve, for example the difference
between the speed setpoint and the speed actual value.
Note
If you use the "record individual bits" or "mathematical functions" option, then this is
displayed under signal No. 9.

External data backup
After commissioning, your settings are saved in the inverter so that they are protected
against power failure.
Further, we recommend that you externally save the parameter settings so that in the case
of a defect, you can simply replace the Power Module or Control Unit (see also Overview of
replacing converter components (Page 281)).
You have three different options for externally backing up data (upload):
1. Memory card
2. PC/PG with STARTER
3. Operator Panel
Series commissioning
Series commissioning means the commissioning of several identical drives in the following
steps:
1. Commission the first inverter.
2. Upload the parameters of the first inverter to an external memory.
3. Download the parameters from the external memory to a second or additional inverter.
Note
The control unit to which the parameters are transferred must be of the same type and
have the same or a higher firmware version as the source control unit (the same 'type'
means the same MLFB).

Backing up and transferring settings using a memory card
What memory cards do we recommend?
The memory card is a removable flash memory, that offers you the following options
● Automatically or manually write parameter settings from the card into the inverter
(automatic or manual download)
● Automatically or manually write parameter settings from the inverter onto the card
(automatic or manual upload)
We recommend that you use one of the memory cards with the following order numbers:
● MMC (order number 6SL3254-0AM00-0AA0)
● SD (order number 6ES7954-8LB00-0AA0)
Using memory cards from other manufacturers
If you use other SD or MMC memory cards, then you must format the memory card as
follows:
● MMC: Format FAT 16
– Insert the card into your PC's card reader.
– Command to format the card:
format x: /fs:fat (x: Drive code of the memory card on your PC)
● SD: Format FAT 32
– Insert the card into your PC's card reader.
– Command to format the card:
format x: /fs:fat32 (x: Drive code of the memory card on your PC.)
CAUTION
You use memory cards from other manufacturers at your own risk. Depending on the
card manufacturer, not all functions are supported (e.g. download).
4.6.1.1
Saving setting on memory card
We recommend that you insert the memory card before switching on the inverter for the first
time. The inverter then automatically ensures that the actual parameter setting is saved both
in the inverter as well as on the card.
The following describes how you can save the inverter parameter setting on the memory
card subsequently.

Preconditions
Before you adapt the inputs and outputs of the inverter, you should have completed the
basic commissioning, see Chapter Commissioning (Page 53) .
In the basic commissioning, select an assignment of the inverter interfaces from several
predefined configurations, see Section Preparing for commissioning (Page 56).
If none of the predefined configurations completely matches your application, then you must
adapt the assignment of the individual inputs and outputs. You do this by changing the
internal interconnection of an input or output using BICO technology (Page 16).

Communication with the controller, even when the supply voltage on the Power Module is
switched off
You will have to supply the Control Unit with 24 V DC on terminals 31 and 32 if you require
communication to take place with the controller when the line voltage is switched off.
6.1.1
Configuring communication to the control
The GSD is a description file for a PROFIBUS slave. You must import the GSD of the
converter into the PROFIBUS master - i.e. into your control system - in order to configure
communication between the control system and converter.
You have two options for obtaining the GSD of your converter:
1. You can find the SINAMICS converter GSD on the Internet
(http://support.automation.siemens.com/WW/view/en/22339653/133100).
2. The GSD is saved in the converter. The GSD is written to the memory card if you insert
the memory card in the converter and set p0804 to 12. Using the memory card, you can
then transfer the GSD to your PG/your PC.
In Section Application examples (Page 323) you will find an example showing how you can
connect the converter with its GSD to a SIMATIC control via PROFIBUS.

Setting the address
You can set the inverter's PROFIBUS address using either DIP switches on the Control Unit
or parameter p0918.
Valid PROFIBUS addresses:
1 … 125
Invalid PROFIBUS addresses:
0, 126, 127
If you have specified a valid address using DIP switches, this address will always be the one
that takes effect and p0918 cannot be changed.
If you set all DIP switches to "OFF" (0) or "ON" (1), then p0918 defines the address.
The positions and settings of the DIP switches are described in Section: Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
CAUTION
A bus address that has been changed is only effective after the inverter has been switched
off and back on again.

Using parameter p0922, you automatically interconnect the corresponding signals of the
converter to the telegram.
This BICO interconnection can only be changed, if you set p0922 to 999. In this case, select
your required telegram using p2079 and then adapt the BICO interconnection of the signals.

Description
PROFIdrive PZD telegram selection extended
Contrary to p0922, using p2079, a telegram can be set and subsequently extended.
For p0922 < 999, the following applies: p2079 has the same value and is locked. All of
the interconnections and extensions contained in the telegram are locked.
For p0922 = 999, the following applies: p2079 can be freely set. If p2079 is also set to
999, then all interconnections can be set.
For p0922 = 999 and p2079 < 999, the following applies: The interconnections
contained in the telegram are locked. However, the telegram can be extended.

Select telegram
Select the communication telegram using parameters p0922 and p2079. The following
dependencies apply:
● P0922 < 999:
For p0922 < 999, the inverter sets p2079 to the same value as p0922.
With this setting, the inverter defines the length and the content of the telegram. The
inverter does not permit any changes to the telegram.
● p0922 = 999, p2079 < 999:
For p0922 = 999, select a telegram via p2079.
Also with this setting, the inverter defines the length and the content of the telegram. The
inverter does not permit any changes to the telegram content. However, you can extend
the telegram.
● p0922 = p2079 = 999:
For p0922 = p2079 = 999, enter the length and the content of the telegram.
With this setting, you can define the telegram length via the central PROFIdrive
configuration in the master. You define the telegram contents via the signal
interconnections of the BICO technology. Using p2038, you can define the assignment of
the control word according to SINAMICS or VIK/NAMUR.
You will find more details on the interconnection of command and setpoint sources,
depending on the selected protocol, in the List Manual in function block diagrams 2420 to

Structure of the parameter index (IND)
● For indexed parameters, select the index of the parameter by transferring the appropriate
value between 0 and 254 to the subindex within a job.
● The page index is used to switch over the parameter numbers. Use this byte to add an
offset to the parameter number that is transferred in the 1st word of the parameter
channel (PKE).
Page index: Offset of parameter number
The parameter numbers are assigned to several parameter ranges. The following table
shows which value you must transfer to the page index to achieve a particular parameter
number.

Parameter value (PWE)
The parameter value (PWE) is transferred as a double word (32 bits). Only one parameter
value may be transferred per telegram.
A 32 bit parameter value includes PWE1 (H word, 3rd word) and PWE2 (L word, 4th word).
A 16 bit parameter value is transferred in PWE2 (L word, 4th word). In this case, PWE1 (H
word, 3rd word) must be set to 0.

Example of read request for parameter P7841[2]
To obtain the value of the indexed parameter P7841, you must fill the telegram of the
parameter channel with the following data:
● Request parameter value (field): Bits 15 … 12 in the PKE word:
Request identifier = 6
● Parameter number without offset: Bits 10 … 0 in the PKE word:
Because you can only code parameter numbers from 1 … 1999 in the PKE, you must
deduct as large an offset as possible, a number divisible by 2000, from the parameter
number, and transfer the result of this calculation to the PKE word.
In our example, this means: 7841 - 6000 = 1841
● Coding the offset of the parameter number in the page index byte of the IND word:
In this example: When offset = 6000, this corresponds to a page index value of 0x90.
● Index of parameter in the subindex byte of the IND word:
In this example: Index = 2
● Because you want to read the parameter value, words 3 and 4 in the parameter channel
for requesting the parameter value are irrelevant. They should be assigned a value of 0,
for example.

Rules for editing requests and responses
● You can only request one parameter per transmitted telegram
● Each received telegram contains only one response
● The request must be repeated until the right response is received
● The response is assigned to a request by means of the following identifiers:
– Suitable response identifier
– Suitable parameter number
– Suitable parameter index IND, if required
– Suitable parameter value PWE, if necessary
● The complete request must be sent in a telegram. Request telegrams cannot be
subdivided. The same applies to responses.

6.1.4.4
Slave-to-slave communication
With "Slave-slave communication" ( also called "Data Exchange Broadcast") it is possible to
quickly exchange data between inverters (slaves) without the master being directly involved,
for instance to use the actual value of one inverter as setpoint for other inverters.
For slave-to-slave communication, in the control system you must define which inverter acts
as publisher (sender) or subscriber (receiver) - and which data or data areas (access points)
you wish to use for slave-to-slave communication. In the inverters that operate as subscriber,
you must define how the data transferred using slave-to-slave communication is processed.
Using parameter r2077, in the inverter, you can read-out the PROFIBUS addresses of the
inverters for which the slave-to-slave communication function is configured.
● Publisher Slave, which sends the data for slave-to-slave communication.
● Subscriber Slave, which receives the data from slave-to-slave communication from the
publisher.
● Links and access points define the data that are used for slave-to-slave communication.
You must observe the following restrictions for the slave-to-slave communication function:
● a maximum of 8 PZD are permissible for each drive
● To a publisher, a maximum of 4 links are possible
An example of how you configure slave-to-slave communication between two inverters in
STEP 7 is provided in Section: Configuring slave-to-slave communication in STEP 7
(Page 334).

Acyclic communication
As from performance level DP-V1, PROFIBUS communications offer acyclic data
communications apart from cyclic communications. You can parameterize and troubleshoot
(diagnostics) the inverter via acyclic data transfer. Acyclic data is transferred in parallel with
cyclic data transfer but with a lower priority.
The inverter supports the following data transfer types:
● Reading and writing parameters via "data set 47" (up to 240 bytes per write or read
request)
● Reading-out profile-specific parameters
● Data exchange with a SIMATIC HMI (Human Machine Interface)
You can find a STEP 7 program example for acyclic data transfer in Section STEP 7
program example for acyclic communication (Page 330).

Communication via USS
Using the USS protocol (protocol of the universal serial interface), users can set up a serial
data connection between a higher-level master system and several slave systems (RS 485
interface). Master systems include programmable logic controllers (e.g. SIMATIC S7-200) or
PCs. The inverters are always slaves on the bus system.
Communication using the USS protocol takes place over the RS485 interface with a
maximum of 31 slaves.
The maximum cable length is 1200 m (3300 ft)
Information about how to connect the inverter to the USS fieldbus is provided in Section:
Integrating inverters into a bus system via the RS485 interface (Page 118).
6.2.2.1
Setting the address
You can set the inverter's USS address using either DIP switches on the Control Unit or
parameter p2021.
Valid USS addresses:
1 … 30
Invalid USS addresses:
0, 31 … 127
If you have specified a valid address using DIP switches, this address will always be the one
that takes effect and p2021 cannot be changed.
If you set all DIP switches to "OFF" (0) or "ON" (1), then p2021 defines the address.
The positions and settings of the DIP switches are described in Section Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
CAUTION
A bus address that has been changed is only effective after the inverter has been switched
off and back on again.

The length for the parameter channel is determined by parameter p2023 and the length for
the process data is specified by parameter p2022. If the parameter channel or the PZD is not
required, the appropriate parameters can be set to zero ("PKW only" or "PZD only").
It is not possible to transfer "PKW only" and "PZD only" alternatively. If both channels are
required, they must be transferred together.
6.2.2.5
Data structure of the USS parameter channel
The USS protocol defines for inverters the user data structure via which a master accesses
the slave inverter. The parameter channel is used to read and write parameters in the
inverter.
Parameter channel
You can use the parameter channel with a fixed length of 3 or 4 data words or with a variable
length.
The first data word always contains the parameter identifier (PKE) and the second contains
the parameter index.
The third, fourth and subsequent data words contain parameter values, texts and
descriptions.
Parameter identifier (PKE), 1st word
The parameter identifier (PKE) is always a 16-bit value.

Parameter value (PWE)
You can vary the number of PWEs using parameter p2023.
Parameter channel with fixed length
Parameter channel with variable length
P2023 = 4
P2023 = 127
A parameter channel with fixed length should
contain 4 words as this setting is sufficient for all
parameters (including double words).
For a variable length of parameter channel, the
master will only send the number of PWEs
necessary for the task in the parameter channel.
The response telegram is also no longer than
necessary.
P2023 = 3
You can select this setting if you only want to
read or write 16-bit data or alarm signals.
•
16-bit data: e.g. p0210 supply voltage
•
32-bit data:
Indexed parameter, e.g. p0640[0…n]
Bit parameter, e.g. 722.0...12
The master must always transmit the
permanently set number of words in the
parameter channel. Otherwise the slave will not
respond to the telegram.
When the slave responds it must always respond
with the defined number of words.
Note
8-bit values are transmitted as 16-bit values; the higher-order byte is zero. The fields of 8-bit
values require one PWE per index.
Rules for editing requests/responses
● You can only request one parameter for each telegram sent.
● Each received telegram contains only one response.
● The master must repeat a request until it receives a suitable response.
● Request and response are assigned to one another using the following identifiers:
– Suitable response identifier
– Suitable parameter number
– Suitable parameter index IND, if required
– Suitable parameter value PWE, if necessary
● The master must send the complete request in one telegram. Request telegrams cannot
be split up. The same applies to responses.

USS read request
Example: Reading out alarm messages from the inverter.
The parameter channel comprises four words (p2023 = 4). In order to obtain the values of
the indexed parameter r2122, you must fill the telegram of the parameter channel with the
following data:
● Request parameter value (field): Bits 15 … 12 in the PKE word:
Request identifier = 6
● Parameter number without offset: Bits 10 … 0 in the PKE word:
Because you can only code parameter numbers from 1 … 1999 in the PKE, you must
deduct as large an offset as possible, a number divisible by 2000, from the parameter
number, and transfer the result of this calculation to the PKE word.
In our example, this means: 2122 - 2000 = 122 = 7AH
● Offset of the parameter number in the byte page index of the word IND:
for this example: When offset = 2000, this corresponds to a page index value of 0x80
● Index of the parameter in the byte subindex of the word IND:
If you wish to read-out the last alarm, then you must enter index 0, for the third from last,
index 2 (example). You can find a detailed description on the history of the alarm
messages in the Section Alarms (Page 288) .
● Because you want to read the parameter value, words 3 and 4 in the parameter channel
for requesting the parameter value are irrelevant. They should be assigned a value of 0,
for example.

Example: Define digital input 2 as source for ON/OFF in CDS1
In this case, parameter p0840[1] (source, ON/OFF) must be assigned the value 722.2 (digital
input 2).
The parameter channel comprises four words (p2023 = 4). To change the value of the
indexed parameter P0840, you must fill the telegram of the parameter channel with the
following data:
● Change parameter value (field): Enter bit 15 … 12 in PKE (1st word):
Request identifier = 7
● Parameter number without offset: Enter bit 10 … 0 in PKE (1st word):
As the parameter is < 1999, it can be directly entered without an offset - converted into
hex - in the example 840 = 348H.
● Enter the offset of the parameter number in byte page index of word IND (2nd word):
in this example = 0.
● Enter the index of parameter in the byte subindex of word IND (2nd word):
for this example = 1 (CDS1)
● Enter a new parameter value in PWE1 (Word3):
in the example 722 = 2D2H.
● Drive Object: Enter bit 10 … 15 in PWE2 (4th word):
for SINAMICS G120, always 63 = 3FH

The number of PZD words in a USS telegram is defined by parameter p2022. The first two
words are:
● Control 1 (STW1, r0054) and main setpoint (HSW)
● Status word 1 (ZSW1, r0052) and main actual value (HIW)
If P2022 is greater than or the same as 4, the additional control word (STW2, r0055) is
transferred as the fourth PZD word (default setting).
You define the sources of the PZD using parameter p2051.

Telegram monitoring of the master
With your USS master, we recommend that the following times are monitored:
• Response delay:
Response time of the slave to a request from the master
The response delay must be < 20 ms, but longer than the start
delay
• Telegram runtime:
Transmission time of the response telegram sent from the slave
Telegram monitoring of the converter
The converter monitors the time between two requests of the master. Parameter p2040
defines the permissible time in ms. If a time p2040 ≠ 0 is exceeded, then the converter
interprets this as telegram failure and responds with fault F01910.
150% of the residual runtime is the guide value for the setting of p2040, i.e. the telegram
runtime without taking into account the character delay times.
For communication via USS, the converter checks bit 10 of the received control word 1. If the
bit is not set when the motor is switched on ("Operation"), then the converter responds with
fault F07220.

Communication over Modbus RTU
Overview of communication using Modbus
The Modbus protocol is a communication protocol with linear topology based on a
master/slave architecture.
Modbus offers three transmission modes:
● Modbus ASCII
Data is transferred in ASCII code. The data can therefore be read directly by humans,
however, the data throughput is lower in comparison to RTU.
● Modbus RTU
Modbus RTU (RTU: Remote Terminal Unit): Data is transferred in binary format and the
data throughput is greater than in ASCII code.
● Modbus TCP
This type of data transmission is very similar to RTU, except that TCP/IP packages are
used to send the data. TCP port 502 is reserved for Modbus TCP. Modbus TCP is
currently undergoing definition as a standard (IEC PAS 62030 (pre-standard)).
The Control Unit supports Modbus RTU as a slave with even parity.

● Communication using Modbus RTU takes place over the RS485 interface with a
maximum of 247 slaves.
● The maximum cable length is 1200 m (3281 ft).
● Two 100 kΩ resistors are provided to polarize the receive and send cables.
CAUTION
It is not permitted to change over the units!

Setting the address
You can set the inverter's Modbus RTU address using either DIP switches on the Control
Unit or parameter p2021.
Valid Modbus RTU addresses:
1 … 247
Invalid Modbus RTU addresses:
0
If you have specified a valid address using DIP switches, this address will always be the one
that takes effect and p2021 cannot be changed.
If you set all DIP switches to "OFF" (0) or "ON" (1), then p2021 defines the address.
The positions and settings of the DIP switches are described in Section Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
CAUTION
A bus address that has been changed is only effective after the inverter has been switched
off and back on again.

Modbus register and Control Unit parameters
Since the Modbus protocol can only handle register or bit numbers for addressing the
memory, assignment to the appropriate control words, status words and parameters is
performed on the slave side.
The converter supports the following addressing ranges:

Write and read access via FC 3 and FC 6
Function codes used
For data exchange between the master and slave, predefined function codes are used for
communication via Modbus.
The Control Unit uses the Modbus function code 03, FC 03, (read holding registers) for
reading and the Modbus function code 06, FC 06, (preset single register) for writing.
Structure of a read request via Modbus function code 03 (FC 03)
All valid register addresses are permitted as a start address. If a register address is invalid,
exception code 02 (invalid data address) is returned. An attempt to read a write-only register
or a reserved register is replied to with a normal telegram in which all values are set to 0.
Using FC 03, it is possible to address more than 1 register with one request. The number of
addressed registers is contained in bytes 4 and 5 of the read request.
Number of registers
If more than 125 registers are addressed, exception code 03 (Illegal data value) is returned.
If the start address plus the number of registers for an address are outside of a defined
register block, exception code 02 (invalid data address) is returned.

Structure of a write request via Modbus function code 06 (FC 06)
The start address is the holding register address. If an incorrect address is entered (a
holding register address does not exist), exception code 02 (invalid data address) is
returned. An attempt to write to a "read-only" register or a reserved register is replied to with
a Modbus error telegram (Exception Code 4 - device failure). In this instance, the detailed
internal error code that occurred on the last parameter access via the holding registers can
be read out via holding register 40499.
Using FC 06, precisely one register can always be addressed with one request. The value
which is to be written to the addressed register is contained in bytes 4 and 5 of the write
request.

Communication procedure
Procedure for communication in a normal case
Normally, the master sends a telegram to a slave (address range 1 ... 247). The slave sends
a response telegram to the master. This response telegram mirrors the function code, and
the slave enters its own address in the telegram, which enables the master to assign the
slave.
The slave only processes orders and telegrams which are directly addressed to it.
Communication errors
If the slave detects a communication error on receipt (parity, CRC), it does not send a
response to the master (this can lead to "setpoint timeout").

Configuring the fieldbus
6.2 Communication via RS485
Logical error
If the slave detects a logical error within a request, it responds to the master with an
"exception response". In the response, the highest bit in the function code is set to 1. If the
slave receives, for example, an unsupported function code from the master, the slave
responds with an "exception response" with code 01 (Illegal function code).

Server failure

Maximum processing time, p2024[0]
For error-free communication, the slave response time (time within which the Modbus master
expects a response to a request) must have the same value in the master and the slave
(p2024[0] in the converter).
Process data monitoring time (setpoint timeout), p2040
The alarm "Setpoint timeout" (F1910) is issued by the Modbus if p2040 is set to a value > 0
ms and no process data are requested within this time period.
The alarm "Setpoint timeout" only applies for access to process data (40100, 40101, 40110,
40111). The alarm "Setpoint timeout" is not generated for parameter data (40200 … 40522).
Note
This time must be adapted depending on the number of slaves and the baud rate set for the
bus (factory setting = 100 ms).

Communication via BACnet MS/TP
BACnet properties
In BACnet, components and systems are considered to be black boxes which contain a
number of objects. BACnet objects only define behavior outside the device, internal functions
are not determined by BACnet.
Each component is represented by a series of object types and their instances.
Each BACnet device has precisely one BACnet device object. A BACnet device is clearly
identified by an NSAP (Network Service Access Point - comprising network number and
MAC address; MAC: Medium Access Control). This address is BACnet-specific and must not
be confused with the Ethernet MAC address.
Data exchange with the client
The inverter receives control commands and setpoints via service instructions from the
control and transmits its status back to the control. The inverter can also send telegrams
automatically itself, respectively execute services, e.g. I-Am.
Communication settings
● The Control Unit supports BACnet via RS485 (BACnet MS/TP)
● The maximum cable length is 1200 m (3281 ft).
Protocol Implementation Conformance Statement
You will find the Protocol Implementation Conformance Statement (PICS) in the Internet
under the following link: BACnet files

CAUTION
It is not permitted to change over the units!
The "Unit changeover (Page 219)" function is not permissible with this bus system!

6.2.4.1
Setting the address
You can define the MAC ID of the inverter using DIP switches on the Control Unit or using
p2021.
Valid BACnet addressing range: 1 … 127
If you specify the address using the DIP switch, then this address is always effective and
p2021 cannot be changed.
If you want to specify the address using p2021, we recommend setting all the DIP switches
to "OFF" (0).
The positions and settings of the DIP switches are described in Section Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
CAUTION
A bus address that has been changed is only effective after switching-off and switching-on
again. It is particularly important that any external 24 V supply is switched off.

Setting of the COV_Increment
(COV = Change of values) 0 … 4194303.000, factory setting = 0.100
COV_Increment: Value change of the "Present Value" of an object instance where
an UnConfirmedCOVNotification or ConfirmedCOVNotification should be
transferred from the server.
•
p2026 [0]: COV increment of object instance "Analog Input 0"
•
p2026 [1]: COV increment of object instance "Analog Input 1"
•
p2026 [2]: COV increment of object instance "Analog Input 10"
• p2026 [3]: COV increment of object instance "Analog Input 11"
You can use these parameters to set for which value changes an
UnConfirmedCOVNotification or ConfirmedCOVNotificationresult is sent.
Therefore, the factory setting 0.100 means that an UnConfirmedCOVNotification or
ConfirmedCOVNotification is sent if the value being considered (e.g. for a control
range from 0 … 10 V) changes by an absolute value of ≥ 0.1. Of course this only
applies if previously a SubscribeCOV service was activated for the particular object
instance.
You can also set the COV increment using the object property "COVIncrement" of
the particular analog input.

Fieldbus monitoring time
0 ms … 65535000 ms, factory setting = 100 ms
Note: The factory setting for communication with BACnet is possibly too low and
must be increased. Please adapt the value to the requirements and properties of
your particular plant or system.
The reason for the factory setting of 100 ms is that the communication protocols
for USS and Modbus RTU should also be executed via the RS485 interface.

Supported services and objects
BIBBs used by the inverter
The BIBBs are a collection of one or several BACnet services The BACnet services are subdivided into A and B devices. An A device operates as client and B device as server.
The inverter is a server and therefore operates as B device, as "BACnet Application Specific
Controller" (B-ASC).

Communication over CANopen
Connecting an inverter to a CAN bus
Connect the inverter to the fieldbus via the 9-pin SUB-D pin connector.
The connections of this pin connector are short-circuit proof and isolated. If the inverter
forms the first or last slave in the CANopen network, then you must switch-in the bus
terminating resistor.
For additional information on the SUB-D pin connector and on the bus terminating resistor,
please refer to Section Interfaces, connectors, switches, control terminals, LEDs on the CU
(Page 46).
Integrating the converter into CANopen
We recommend the following procedure to integrate the converter into CANopen:
1. Setting the node ID and baud rate
2. Monitoring the communication and response of the inverter (Page 155) set
3. Integrating the converter into CAN using the Predefined Connection Set
4. if required, make additional specific changes using the free PDO mapping.
5. Adapting the BiCo interconnection
Note
In the configuration example (Page 179) you can find a detailed description of how you
integrate the converter into a CANopen system.
More information about how to configure the communication is provided in Sections Other
CANopen functions (Page 167) and Object directories (Page 170).
General information on CAN
You can find general information on CAN in the CAN Internet pages (http://www.can-cia.org);
you can obtain an explanation of CAN terminology in the CANdictionary under CAN
downloads (http://www.can-cia.org/index.php?id=6).
The EDS file is the description file of the SINAMICS G120 converter for CANopen networks.
If you load the EDS file into your CAN controller, you can use the objects of the DSP 402
device profile.
1. You can find the EDS file of the converter inInternet
(http://support.automation.siemens.com/WW/view/en/48351511).
In Section Configuration example (Page 179), you can find an example of how you can
integrate the converter into a CAN controller using the EDS.

6.3 Communication over CANopen
6.3.1
CANopen functionality of the converter
CANopen is a CAN-based communication protocol with linear topology that operates on the
basis of communication objects (COB).
Communication between the converter and control can be established via Predefined
connection set (Page 165) or via Free PDO mapping (Page 166)
Communication objects (COB)
The converter operates with communication objects from the following profiles:
● CANopen communication profile DS 301 version 4.0
● Device profile DSP 402 (drives and motion control) version 2.0
● Indicator profile DR303-3 version 1.0.
Specifically, these are:
● SDO
Service data objects for reading and changing parameters
● PDO
Process data objects to transfer process data, TPDO to send, RPDO to receive
● NMT
Network management objects (NMT) for controlling CANopen communication and for
monitoring the individual nodes on the basis of a master-slave relationship.
● SYNC
Synchronization objects
● EMCY
Time stamp and fault messages
COB ID
A communication object includes data – which is transferred – and an 11 bit COB-ID, which
uniquely identifies it. The priority when executing the communication objects is controlled
using the COB-ID. The communication object with the lowest COB-ID always has the highest
priority.
COB ID for individual communication objects
You will find the specifications for the COB IDs of the individual communication objects
below
• COB IDNMT = 0
cannot be changed
• COB IDSYNC = free
in most cases, this is preassigned with 80 hex
• COB IDEMCY = free
In most of the cases, COB IDSYNC + node-ID = COB-IDEMCY
• COB-IDTPDO= free
In the free PDO mapping *)
• COB-IDRPDO= free

• COB IDTSDO = 580 + Node-ID
• COB IDRSDO = 600 + Node-ID
• COB IDNode Guarding/Heartbeat= 700 + Node-ID

Commissioning CANopen
6.3.2.1
Setting the node ID and baud rate
In the converter you must set the node ID and the baud rate to permit communication.
CAUTION
Changes made to the node ID or baud rate only become effective after switching off and on
again. It is particularly important that any external 24 V supply is switched off.
Note that before turning off, you must save the changes using RAM -> ROM (
).
The currently active Node ID is displayed in parameter r8621.
Setting the node ID
You can define the node ID either using the DIP switch on the Control Unit, using parameter
p8620 or in STARTER in the screen form under "Control Unit/Communication/CAN" under
the CAN interface tab.
Valid node IDs:
1 … 126
Invalid node IDs:
0, 127
When a valid node ID has been set using DIP switches, then this is always effective and
p8620 cannot be changed.
If you set all DIP switches to "OFF" (0) or "ON" (1), then the Node ID set in p8620 or
STARTER is effective.
The positions and settings of the DIP switches are described in Section Interfaces,
connectors, switches, control terminals, LEDs on the CU (Page 46).
Setting the data transmission rate
You can set the transmission rate in the range from 10 kbit/s … 1 Mbit/s using parameter
p8622 or in the STARTER screen form "Control Unit/Communication/CAN" under the CAN
interface tab.

6.3 Communication over CANopen
6.3.2.2
Monitoring the communication and response of the inverter
The communication monitoring can be used via both node guarding and heartbeat protocol
(heartbeat producer).
Node guarding
The master sends monitoring queries to the slaves via the node guarding protocol.
If the converter does not receive a Node Guarding protocol within the Life Time, then it
outputs fault (F08700).
Life Time = Guard time (p8601.0) * Life Time Factor (p8604.1)
Heartbeat
The slave periodically sends heartbeat messages. Other slaves and the master can monitor
this message. If a heartbeat goes missing, then appropriate responses can be set in the
master.
The settings for the heartbeat protocol are made in parameter p8606.
Note
Note
Node guarding and heartbeat are mutually interlocked. This means that if the parameter for
one of these functions is not equal to 0, then the other cannot be used.
Both functions are deactivated in the factory setting.
Converter response to a bus fault - CAN controller state "Bus off"
(converter fault F8700, fault value 1)
If you acknowledge the bus fault using OFF/ON, the bus OFF state is also canceled and
communication is restarted.
If you acknowledge the bus fault via DI 2 or directly via p3981, then the converter remains in
the bus OFF state. To restart communication, in this case, you must set p8608 to 1.
WARNING
If you acknowledge the bus fault via DI 2 or directly via p3981 - and p8641 is set to 0 (for a
bus fault, the converter does not go into a fault condition), then you must restart
communication via p8608 = 1 before you can stop the motor via the control.

SDO services
You can access the object directory of the connected drive unit using the SDO services. An
SDO connection is a peer-to-peer coupling between an SDO client and a server.
The drive unit with its object directory is an SDO server.
The identifiers for the SDO channel of a drive unit are defined according to CANopen as
follows.
Receiving:
Server <= Client:
COB ID = 600 hex + node ID
Transmitting:
Server => Client:
COB ID = 580 hex + node ID
Properties
The SDOs have the following properties:
● SDO are transferred in the Preoperational and Operational states
● The transfer is confirmed
● Transfer is asynchronous (corresponds to acyclic data exchange for PROFIBUS DB)
● Transmission of values > 4 bytes (normal transfer)
● Transmission of values ≤ 4 bytes (expedited transfer)
● All drive unit parameters can be addressed via SDO.

Access to SINAMICS parameters via SDO
If you wish to change inverter parameters in CANopen using the control, then use the
service data objects (SDO). SDO are transferred in the operational as well as in the preoperational states.
You can also configure RPDO and TPDO telegrams via SDO. You can find the objects that
are available to do this in Section Object directories (Page 170).
Adapting the parameter numbers
The inverter parameters can be addressed via the SDO parameter channel in the range from
2000 hex ... 470F hex of the CANopen object directory.

Configuring the fieldbus
6.3 Communication over CANopen
Not all of the parameters can be directly addressed via this range. This is the reason that in
CAN, an inverter parameter always comprises two parameters from the inverter; these are
the offset specified using parameter p8630[2] and the parameter itself.
● for all parameters < 9999 the following applies:
– p8630[2] = 0,
– Inverter parameters -> hex + 2000 hex
Example: For parameter p0010, 200A hex follows as object number in the SDO job
● for all parameters 9999 < 19999 the following applies:
– p8630[2] = 1,
– (inverter parameters - 10000) -> hex + 2000 hex
Example: For parameter p11000, 23E8 hex follows as object number in the SDO job
● for all parameters 19999 < 29999 the following applies:
– p8630[2] = 2,
– (inverter parameters - 20000) -> hex + 2000 hex
Example: For parameter r20001, 2001 hex follows as object number in the SDO job
● for all parameters 29999 < 39999, the following applies:
– p8630[2] = 3,
– (inverter parameters - 30000) -> hex + 2000 hex
Example: For parameter p31020, 23FC hex follows as object number in the SDO job
Selection, index range
Further, no more than 255 indices can be transferred in a CANopen object. This means that
additional CANopen objects must be created for parameters that have more indices. This is
realized using p8630[1]. It is possible to transfer a maximum of 1024 indices.
● P8630[1] = 0: 0 … 255
● P8630[1] = 1: 256 … 511
● P8630[1] = 2: 512 … 767
● P8630[1] = 3: 768 … 1023
Accessing CANopen objects and inverter parameters
● p8630[0] = 0: only accessing CANopen objects (SDO, PDO, ... )
● p8630[0] = 1: Access to virtual CANopen objects (inverter parameters)
● p8630[0] = 2: not relevant for G120 inverters

PDO and PDO services
Process data objects (PDO)
For CANopen, (real-time) transfer of process data is realized using "Process Data Objects"
(PDO). There are send and receive PDO. With the G120 inverter, eight send PDO (TPDO)
and eight receive PDO (RPDO) are transferred.
A PDO is defined by the PDO communication parameter and the PDO mapping parameter.
The PDO must be linked with the objects of the object dictionary which contain process data.
You can use Free PDO mapping (Page 166) or the Predefined connection set (Page 165) to
do this.
Note
Changing over between an interconnection via free PDO mapping and Predefined
Connection Set
For changing over from free PDO mapping (factory setting) to mapping via the Predefined
Connection Set you require parameters p8744 and p8741 from the expert list.
You can select the method of the interconnection using p8744 (p8744 = 0: Free PDO
mapping, p8744 = 1: Predefined Connection Set), with p8741 =1 you confirm the transfer.
After transfer, p8741 returns to 0.
Parameter area for PDO
● RPDO
– In the inverter: p8700 … p8717
– In CAN:

● TPDO
– In the inverter: p8720 … p8737

Note
One channel in the CAN controller is assigned for each RPDO. TPDO always use two

For process data objects, the following transfer types are available, which you set in index 1
of the communication parameter (p8700 … p8707 / p8720 … p8727) in the inverter.
● Synchronous cyclic (index 1: n = 1 … 240) - for TPDO (Transmit PDO) and RPDO
(Receive PDO):
– TPDO is sent after each nth SYNC
– RPDO is received after each nth SYNC
● Synchronous acyclic (index 1: 0) - for TPDO
– TPDO is sent if a SYNC is received and a process data has changed in the telegram.
● asynchronous cyclic (index 1: 254, 255 + event time) - for TPDO
– TPDO is sent if process data has changed in the telegram.
● asynchronous acyclic (index 1: 254, 255) - for TPDO and RPDO
– TPDO is sent if process data has changed in the telegram.
– RPDO is directly accepted when it is received.

Synchronous data transmission
In order for the devices on the CANopen bus to remain synchronized during transmission, a
synchronization object (SYNC object) must be transmitted at periodic intervals.
Each PDO that is transferred as a synchronous object must be assigned a transmission type
1 ... n. The following is applicable:
● Transmission type 1: the PDO is transferred in every SYNC cycle.
● Transmission type n: the PDO is transferred in every nth SYNC cycle.
The following diagram shows the principle of synchronous and asynchronous transmission:

Principle of synchronous and asynchronous transmission
For synchronous TPDOs, the transmission mode also identifies the transmission rate as a
factor of the SYNC object transmission intervals. Here, transmission type "1" means that the
message will be transmitted in every SYNC object cycle. Transmission type "n" means that
the message will be transmitted in every nth SYNC object cycle.
Data from synchronous RPDOs that are received after a SYNC signal is not transmitted to
the application until after the next SYNC signal.
Note
The SYNC signal does not synchronize the applications in the SINAMICS drive, only the
communication on the CANopen bus
Asynchronous data transmission
Asynchronous PDOs are transferred - cyclically or acyclically - without reference to the
SYNC signal.

PDO services
The PDO services can be subdivided as follows:
● Write PDO
● Read PDO
● SYNC service
Write PDO
The "Write PDO" service is based on the "push" model. The PDO has exactly one producer.
There can be no consumer, one consumer, or multiple consumers.
Via Write PDO, the producer of the PDO sends the data of the mapped application object to
the individual consumer.
Read PDO
The "Read PDO" service is based on the "pull" model. The PDO has exactly one producer.
There can be one consumer or multiple consumers.
Via Read PDO, the consumer of the PDO receives the data of the mapped application object
from the producer.
SYNC service
The SYNC object is periodically sent from the SYNC producer. The SYNC signal represents
the basic network cycle. The time interval between two SYNC signals is determined in the
master by the standard parameter "Communication cycle time".
In order to ensure CANopen accesses in real-time, the SYNC object has a high priority,
which is defined using the COB ID. This can be changed via p8602 (factory setting = 80hex).
The service runs unconfirmed.
Note
The COB ID of the SYNC object must be set to the same value for all nodes of a bus that
should respond to the SYNC telegram from the master
The COB ID of the SYNC object is defined in object 1005h (p8602).

Predefined connection set
When integrating the converter via the predefined connection set, the converter is
interconnected so that the motor can be switched-on via the control and a setpoint can be
entered without having to make any additional settings or requiring CANopen know-how. The
converter returns the status word and the speed actual value to the control.
In the factory, the converter is set to free PDO mapping. Changeover to the Predefined
Connection Set, see Section PDO and PDO services (Page 161).
Once you have made the settings for the predefined connection set, then in the screen form
"Control Unit/Communication/CAN", select the Operational status under the NetworkManagement tab. You can then switch-on the motor from the control and enter a setpoint.
Data, which you transfer using the predefined connection set
• TPDO 1 with
Control word 1
• RPDO 1 with
Status word 1
• TPDO 2 with
Control word 1 and speed setpoint
• RPDO 2 with
Status word 1 and speed actual value
The COB IDs are calculated according to the following formula and entered into parameters
p8700, p8701, p8720 and 8721.
COB-Id for TPDO and RPDO in the Predefined Connection Set
• COB-IDTPDO = 180 hex + Node-ID + ((TPDO-No. - 1) * 100 hex)
Example: COB-ID of the TPDO 2, (Node ID = C hex)
180 hex + C hex + ((2 - 1)*100 hex) = 18C hex + 100 hex = 28C hex is
required
• COB IDRPDO = 200 hex + Node-ID + ((RPDO-No. - 1) * 100 hex)
Example: COB-ID of the 3rd RPDO, (Node ID = C hex)
200 hex + C hex + ((2 - 1) * 100 hex) = 20C hex + 100 hex = 30C hex is
required

Free PDO mapping
Using the free PDO mapping, you can interconnect additional process data from the object
directory corresponding to the requirements of your particular system for the PDO service.
In the factory, the converter is set to free PDO mapping. If your converter has been changed
over to the Predefined Connection Set, you must change over to free PDO mapping, see
Section PDO and PDO services (Page 161).
A PDO can transfer up to eight bytes of user data. With mapping, you define which user data
are transferred in a PDO.
Example
The following diagram shows an example of PDO mapping (values are hexadecimal (e.g.
object size 10 hex = 16 bits)):

Network management (NMT service)
Network management (NMT) is node-oriented and has a master-slave topology.
The NMT services can be used to initialize, start, monitor, reset, or stop nodes. Two data
bytes follow each NMT service. All NMT services have the COB ID = 0. This cannot be
changed.
The SINAMICS converter is an NMT slave and can adopt the following states in CANopen:
● Initializing
The converter passes through this state after Power On. In the factory setting, the
converter then enters the "Pre-Operational" state, which also corresponds to the
CANopen standard.
Using p8684, you can set that after the bus has booted, the converter does not go into
the "Pre-Operational" state, but instead, into the "Stopped" or "Operational" state.
● Pre-Operational
In this state, the node cannot process any process data (PDO). It can, however, be
parameterized or operated via SDOs, which means that you can also enter setpoints via
SDO.
● Operational
In this state, the node can process both SDO and PDO.
● Stopped
In this state, the node cannot process either PDO or SDO. The Stopped mode is exited
by specifying one of the following commands:
– Enter Pre-Operational
– Start Remote Node
– Reset Node
– Reset Communication

6.3 Communication over CANopen
The NMT recognizes the following transitional states:
● Start Remote Node:
command for switching from the "Pre-Operational" communication status to
"Operational". The drive can only transmit and receive process data (PDO) in
"Operational" status.
● Stop Remote Node
command for switching from "Pre-Operational" or "Operational" to "Stopped". The node
can only process NMT commands in the "Stopped" status.
● Enter Pre-Operational
command for switching from "Operational" or "Stopped" to "Pre-Operational". In this state,
the node cannot process any process data (PDO). It can, however, be parameterized or
operated via SDOs, which means that you can also enter setpoints via SDO.
● Reset Node:
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the Reset Node command is issued, all the objects (1000 hex 9FFF hex) are reset to the status that was present after "Power On".
● Reset Communication:
command for switching from "Operational", "Pre-Operational", or "Stopped" to
"Initialization". When the Reset Communication command is issued, all communication
objects (1000 hex - 1FFF hex) are reset to the status that was present after "Power On".

6.3 Communication over CANopen
6.3.5
Configuration example
The following example describes how you can integrate the converter into a CANopen bus
system using STARTER in two steps.
In the first step, the converter is integrated into the communication via the CAN bus using the
Predefined Connection Set. In this case, the control word, the speed setpoint as well the
status word and speed actual value are transferred.
In the second step, using the free PDO mapping, the torque setpoint as well as the current
actual value are mapped and the BiCo wiring established.
Preconditions for integrating in CAN
The following preconditions must be fulfilled in order to be
able to integrate the converter into a CAN bus:
• The converter and motor must have been completely
installed
• STARTER V4.2 or higher has been installed on your
computer.
• You have a CAN controller via which you can control the
converter.
• The converter is connected online with Starter.
• The EDS file has been installed on your CAN controller.

Integrate the converter into a CAN bus system using the Predefined Connection Set
● Carry out the commissioning (Page 68) using the wizards and for the I/O configuration
(second commissioning step) select the setting "22 CAN fieldbus" (macro 15 = 22). As a
consequence, you establish the BICO interconnection of the speed setpoint/control word
as well as speed actual value/status word corresponding to the Predefined Connections
Set.
● In STARTER, in the screen form "…/Control_Unit/Communication/CAN" set the node ID
and data transmission rate (Page 154) - (in the example, Node ID = 50, transmission rate
= 500 kbit/s).
● Using the Expert List, in Starter set the mapping via the Predefined connection set
(Page 165): p8744 = 1 and accept with p8744 = 1 (p8744 jumps back to 0 again after a
few seconds).
As a consequence, you have established communication with CAN via the "Predifined
Connection Set" (speed setpoint/control word as well as the actual value/status word, also
see Objects in drive profile DSP402 (Page 178)).

6.3 Communication over CANopen
Integrate the current actual value and torque limit into the communication via the free PDO mapping
In order to integrate the current actual value and torque limit into the communication, you
must switch over from the Predefined Connection Set to the free PDO mapping. The current
actual value and torque limit are integrated as free objects.
In the example, the actual current value is transferred in TPDO1 and the torque limit in
RPDO1, i.e. it is not necessary to create new communication parameters (node ID and
transmission mode). However, you must map the OD indices for the current actual value and
the torque limits and adapt to the BiCo interconnection.
1. Switching over from the Predefined Connection Set to free PDO mapping
In the expert list, set p8744 to 1.
2. Mapping the current actual value (r0068) with TPDO1
● Define the OD index for the current actual value: 5810
● Set the COB ID from TPDO1 to "Mapping permissible":
p8720[0] = 400001B2H (mapping not permitted) on p8720.0 = 800001B2H (mapping
permissible)
● Set p8730[1] = 5810010H - the first four digits are the OD index for the current actual

7.1 Overview of the inverter functions
Functions relevant to all applications
Functions required in special applications only
The functions that you require in your application are shown
in a dark color in the function overview above.
The functions whose parameters you only need to adapt
when actually required are shown in white in the function
overview above.
In the quick commissioning, the parameters of these
functions are assigned an appropriate basic setting, so that
in many cases the motor can be operated without having to
assign any other parameters.
Inverter control is responsible for all of the other
inverter functions. Among other things, it defines
how the inverter responds to external control
signals.
Inverter control (Page 185)
The production functions avoid overloads and
operating states that could cause damage to the
motor, inverter and driven load. The motor
temperature monitoring, for example, is set
here.
Protection functions (Page 212)
The command source defines where the control
signals are received from to switch on the motor,
e.g. via digital inputs or a fieldbus.
Command sources (Page 194)
The status messages provide digital and analog
signals at the Control Unit outputs or via the
fieldbus. Examples include the current speed of
the motor or fault message issued by the
inverter.
Status messages (Page 218)
The setpoint source defines how the speed
setpoint for the motor is specified, e.g. via an
analog input or a fieldbus.
Setpoint sources (Page 195)
The setpoint processing uses a ramp-function
generator to prevent speed steps occurring and
to limit the speed to a permissible maximum
value.
Setpoint calculation (Page 202)
0
The functions matching the application provide
e.g. the control of a motor holding brake or allow
a higher-level pressure or temperature control to
be implemented using the technology controller.
Further, the inverter provides solution options
specifically for applications in the area of
pumps, fans and climate control systems
(HVAC).
Application-specific functions (Page 219)
The motor closed-loop control ensures that the
motor follows the speed setpoint.

Inverter control
If you are controlling the inverter using digital inputs, you use parameter p0015 during basic
commissioning to define how the motor is switched on and off and how it is changed over
from clockwise to counter-clockwise rotation.
Five different methods are available for controlling the motor. Three of the five methods just
require two control commands (two-wire control). The other two methods require three
control commands (three-wire control).

Switching over the inverter control (command data set)
In several applications, the inverter must be able to be operated from different, higher-level
control systems.
Example: Switchover from automatic to manual operation
A motor is switched on and off and its speed varied either from a central control system via a
fieldbus or from a local control box.
Command data set (CDS)
This means that you can set the inverter control in various ways and toggle between the
settings. For instance, as described above, the inverter can either be operated via a fieldbus
or via the terminal strip.
The settings in the inverter, which are associated with a certain control type of the inverter,
are known as a command data set.
Example:
Command data set 0: Controlling the inverter via the fieldbus
Command data set 1: Controlling the inverter via terminal strip

Command sources
The command source is the interface via which the inverter receives its control commands.
When commissioning, you define this using macro 15 (p0015).
Note
The "Get master control" or "Manual/Auto changeover" function can also be used to specify
commands and setpoints via STARTER or the Operator Panel.
Change command source
If you subsequently change the command source using macro 15, then you must carry out
commissioning again.
You also have the option to adapt the pre-assignment - which you selected using macro 15 to the requirements of your particular system. You can obtain detailed information about this
in the Sections Adapting the terminal strip (Page 85) andConfiguring the fieldbus (Page 97).

● Inverter analog input.
● Setpoints saved in the inverter:
– Fixed setpoints
– Jog
● Inverter fieldbus interface.
Depending on the parameterization, the setpoint in the inverter has one of the following
meanings:
● Speed setpoint for the motor.
● Torque setpoint for the motor.
● Setpoint for a process variable.
The inverter receives a setpoint for a process variable, e.g. the level of liquid in a
container, and calculates its speed setpoint using the internal technology controller.
7.4.1
Analog input as setpoint source
If you use an analog input as setpoint source, then you must adapt this analog input to the
type of connected signal (± 10 V, 4 … 20 mA, …). Additional information is available in
Section Analog inputs (Page 89).
Procedure
You have two options for interconnecting the setpoint source with an analog input:
1. Using p0015, select a configuration that is suitable for your application.
Please refer to the section titled Selecting the interface assignments (Page 48) to find out
which configurations are available for your inverter.
2. Interconnect main setpoint p1070 with an analog input of your choice.

Motorized potentiometer as setpoint source
The 'motorized potentiometer' (MOP) function simulates an electromechanical potentiometer
for entering setpoints. You can continuously adjust the motorized potentiometer (MOP) using
the control signals "raise" and "lower". The control signals are received via the digital inputs
of the inverter or from the operator panel that has been inserted.
Typical applications
● Entering the speed setpoint during the commissioning phase.
● Manual operation of the motor should the higher-level control fail.
● Entering the speed setpoint after changeover from automatic operation to manual
operation.
● Applications with largely constant setpoint and without higher-level control.

Fixed speed as setpoint source
In many applications after switching on the motor, all that is needed is to run the motor at a
constant speed or to switch between different speeds. Examples of this simplified
specification of speed setpoint are:
● Conveyor belt with two different speeds.
● Grinding machine with different speeds corresponding to the diameter of the grinding
wheel.
If you use the technology controller in the inverter, then you can enter process variables that
remain constant over time using a fixed setpoint, e.g.:
● Closed-loop control of a constant flow with a pump.
● Closed-loop control of a constant temperature using a fan.
Procedure
You can set up to 16 various fixed setpoints and select these either via digital inputs or the
fieldbus. The fixed setpoints are defined using parameters p1001 to p1004 and can be
assigned to the corresponding command sources (e.g. the digital inputs) using parameters
p1020 to p1023.

7.4 Setpoint sources
The various fixed setpoints can be selected in two ways:
1. Direct selection:
Precisely one fixed speed setpoint is assigned to each selection signal (e.g. a digital
input). As several selection signals are selected, the associated fixed speed setpoints are
added together to from a total setpoint.
Direct selection is particularly well suited to controlling the motor using the inverter's
digital inputs.
2. Binary selection:
Precisely one fixed speed setpoint is assigned to each possible combination of selection
signals.
Binary selection should preferably be used with a central control and when linking the
inverter to a fieldbus.

Running the motor in jog mode (JOG function)
Using the "jog" function (JOG function), you can switch the motor on and off using a control
command or the operator panel. The speed to which the motor accelerates for "Jog" can be
set.
The motor must be switched-off before you issue the "jog" control command. "Jog" has no
effect when the motor is switched on.
The "Jog" function is typically used to manually switch-on a motor after switching over from
automatic to manual operation.
Setting jogging
The "Jog" function has two different speed setpoints, e.g. for motor counter-clockwise
rotation and clockwise rotation.
With an operator panel, you can always select the "Jog" function. If you wish to use
additional digital inputs as control commands, you must interconnect the particular signal
source with a digital input.

Setpoint processing in the inverter
Minimum speed and maximum speed
The speed setpoint is limited by both the minimum and maximum speed.
When the motor is switched on, it accelerates to the minimum speed regardless of the speed
setpoint. The set parameter value applies to both directions of rotation. Beyond its limiting
function, the minimum speed serves as a reference value for a series of monitoring
functions.
The speed setpoint is limited to the maximum speed in both directions of rotation. The
inverter generates a message (fault or alarm) when the maximum speed is exceeded.
The maximum speed also acts as an important reference value for various functions (e.g. the
ramp-function generator).

Ramp-function generator
The ramp-function generator in the setpoint channel limits the speed of changes to the
speed setpoint. The ramp-function generator does the following:
● The soft acceleration and braking of the motor reduces the stress on the mechanical
system of the driven machine.
● Acceleration and braking distance of the driven machine (e.g. a conveyor belt) are
independent of the motor load.
Ramp-up/down time
The ramp-up and ramp-down times of the rampfunction generator can be set independently of each
other. The times that you select depend purely on
the application in question and can range from just
a few 100 ms (e.g. for belt conveyor drives) to
several minutes (e.g. for centrifuges).
When the motor is switched on/off via ON/OFF1,
the motor also accelerates/decelerates in
accordance with the times set in the ramp-function
generator.

The quick-stop function (OFF3) has a separate ramp-down time, which is set with P1135.

If the ramp-up/down times are too short, the motor accelerates/decelerates with the
maximum possible torque and the set times will be exceeded.
For more information about this function, see the List Manual (function diagram 3060 and the

Extended ramp-function generator
In the extended ramp-function generator, the acceleration process can be made "softer"
using initial and final rounding via parameters p1130 … p1134. Here, the ramp-up and rampdown times of the motor are increased by the rounding times.
Rounding does not affect the ramp-down time in the event of a quick stop (OFF3).

Motor control
For induction motors, there are two different open-loop control or closed-loop control
techniques:
● Open-loop control with V/f-characteristic (V/f control)
● Field-oriented control (vector control)
Criteria for selecting either V/f control or vector control
V/f control is perfectly suitable for almost any application in which the speed of induction
motors is to be changed. Examples of typical applications for V/f control include:
● Pumps
● Fans
● Compressors
● Horizontal conveyors
Commissioning vector control takes more time than when commissioning V/f control. When
compared to V/f control, vector control offers the following advantages:
● The speed is more stable for motor load changes.
● Shorter accelerating times when the setpoint changes.
● Acceleration and braking are possible with an adjustable maximum torque.
● Improved protection of the motor and the driven machine as a result of the adjustable
torque limiting.
● The full torque is possible at standstill.
● Torque control is only possible with vector control.
Examples of typical applications in which vector control is used:
● Hoisting gear and vertical conveyors
● Winders
● Extruders

7.6.1
V/f control
V/f control sets the voltage at the motor terminals on the basis of the specified speed
setpoint. The relationship between the speed setpoint and stator voltage is calculated using
characteristic curves. The required output frequency is calculated on the basis of the speed
setpoint and the number of pole pairs of the motor (f = n * number of pole pairs / 60, in
particular: fmax = p1082 * number of pole pairs / 60). The inverter provides the two most
important characteristics (linear and square-law). User-defined characteristic curves are also
supported.
V/f control is not a high-precision method of controling the speed of the motor. The speed
setpoint and the speed of the motor shaft are always slightly different. The deviation
depends on the motor load. If the connected motor is loaded with the rated torque, the motor
speed is below the speed setpoint by the amount of the rated slip. If the load is driving the
motor (i.e. the motor is operating as a generator), the motor speed is above the speed
setpoint.
The characteristic is selected during commissioning, using p1300.
7.6.1.1
V/f control with linear and square-law characteristic
V/f control with linear characteristic (p1300 = 0):

Additional characteristics for the V/f control
In addition to linear and square-law characteristics, there are the following additional
versions of the V/f control that are suitable for special applications.
Linear V/f characteristic with Flux Current Control (FCC) (P1300 = 1)
Voltage losses across the stator resistance are automatically compensated. This is
particularly useful for small motors since they have a relatively high stator resistance. The
prerequisite is that the value of the stator resistance in P350 is parameterized as accurately
as possible.

Linear V/f characteristic with ECO (p1300 = 4), quadratic V/f characteristic with ECO (p1300 = 7)
ECO mode is suitable for applications with a low dynamic response and constant speed
setpoint, and allows energy savings of up to 40%.
When the setpoint is reached and remains unchanged for 5 s, the inverter automatically
reduces its output voltage to optimize the motor's operating point. ECO mode is deactivated
in the event of setpoint changes or if the inverter's DC-link voltage is too high or too low.
In ECO mode set the slip compensation (P1335) to 100 %. In the event of minor fluctuations
in the setpoint, you have to raise the ramp-function generator tolerance using p1148.
Note: Sudden load variations can cause the motor to stall.

7.6 Motor control
V/f control for drives requiring a precise frequency (textile industry) (p1300 = 5),
V/f control for drives requiring a precise frequency and FCC (p1300 = 6)
These characteristics require the motor speed to remain constant under all circumstances.
This setting has the following effects:
● When the maximum current limit is reached, the stator voltage is reduced but not the
speed.
● Slip compensation is locked.
For more information about this function, see function diagram 6300 in the List Manual.
V/f control with independent voltage setpoint
The interrelationship between the frequency and voltage is not calculated in the inverter, but
is specified by the user. With BICO technology, P1330 defines the interface via which the
voltage setpoint is entered (e.g. analog input → P1330 = 755).
7.6.1.3
Optimizing with a high break loose torque and brief overload
The ohmic losses in the motor stator resistance and the motor cable play a more significant
role the smaller the motor and the lower the motor speed. You can compensate for these
losses by raising the V/f characteristic.
There are also applications where the motor temporarily needs more than its rated current in
the lower speed range or during acceleration in order to adhere to the speed setpoint.
Examples of such applications are:
● Driven machines with a high break loose torque
● Utilizing the brief overload capability of the motor when accelerating
Voltage increase in V/f control (boost)
Voltage losses resulting from long motor cables
and the ohmic losses in the motor are
compensated for using parameter p1310. An
increased break loose torque when starting and
accelerating is compensated using parameter
p1312 and/or p1311.
The voltage boost is active for every
characteristic type of the V/f control. The figure

The voltage boost in V is: 1.732 x rated motor current (p0305) × stator resistance
(r0395) x p1312 / 100%

Vector control
7.6.2.1
Properties of vector control
Using a motor model, the vector control calculates the load and the motor slip. As a result of
this calculation, the inverter controls its output voltage and frequency so that the motor
speed follows the setpoint, independent of the motor load.
Vector control is possible without directly measuring the motor speed. This closed-loop
control is also known as sensorless vector control.
7.6.2.2
Commissioning vector control
Vector control only functions error-free if, during the basic commissioning, the motor data
were correctly parameterized and a motor data identification was performed with the motor in
the cold state.
You can find the basic commissioning in the following sections:
● Commissioning with the BOP-2 (Page 63)

7.6.2.3
Torque control
Torque control is part of the vector control and normally receives its setpoint from the speed
controller output. By deactivating the speed controller and directly entering the torque
setpoint, the closed-loop speed control becomes closed-loop torque control. The inverter
then no longer controls the motor speed, but the torque that the motor generates.
Typical applications for torque control
The torque control is used in applications where the motor speed is specified by the
connected driven load. Examples of such applications include:
● Load distribution between master and slave drives:
The master drive is speed controlled, the slave drive is torque controlled.
● Winding machines
Commissioning the torque control
The torque control only functions error-free if, during the basic commissioning, you correctly
parameterized the motor data and performed the motor data identification with the motor in
the cold state.
You can find the basic commissioning in the following sections:

Protection functions
The frequency inverter offers protective functions against overtemperature and overcurrent
for both the frequency inverter as well as the motor. Further, the frequency inverter protects
itself against an excessively high DC link voltage when the motor is regenerating.
7.7.1
Inverter temperature monitoring
The inverter temperature is essentially determined by the resistive losses of the output
current and the switching losses which occur when pulsing the Power Module. The inverter
temperature falls when either the output current or the pulse frequency of the Power Module
is reduced.
I2t monitoring (A07805 - F30005)
The Power Module's I2t monitoring controls the inverter utilization by means of a current
reference value. The utilization is specified in r0036 [%].
Monitoring the chip temperature of the power unit (A05006 - F30024)
The temperature difference between the power chip (IGBT) and heat sink is monitored using
A05006 and F30024. The measured values are specified in r0037[1] [°C].
Heat sink monitoring (A05000 - F30004)
The power unit heat sink temperature is monitored using A05000 and F30004. The values

Motor temperature monitoring using a temperature sensor
You can use one of the following sensors to protect the motor against overtemperature:
● PTC sensor
● KTY 84 sensor
● ThermoClick sensor
The motor's temperature sensor is connected to the Control Unit.
Temperature measurement via PTC
The PTC sensor is connected to terminals 14 and 15.
● Overtemperature: The threshold value to switch over to an alarm or fault is 1650 Ω. After
the PTC responds, alarm A07910 or shutdown with fault F07011 is initiated
corresponding to the setting in p0610.
● Short-circuit monitoring: Resistance values < 20 Ω indicate a temperature sensor shortcircuit
Temperature measurement using KTY 84
The device is connected to terminals 14 (anode) and 15 (cathode) in the forward direction of
the diode. The measured temperature is limited to between -48 °C and +248°C and is made
available for further evaluation.
● When the alarm threshold is reached (set via p0604; factory setting: 130 °C), alarm
A7910 is triggered. Response -> p0610)
● Fault F07011 is output (depending on the setting in p0610) if
– the fault threshold temperature (settable in p0605) is reached
– the alarm threshold temperature (settable in p0604) is reached and is still present after
the delay time as expired.
Wire-break and short-circuit monitoring via KTY 84
● Wire break: Resistance value > 2120 Ω
● Short circuit: Resistance value < 50 Ω
As soon as a resistance outside this range is measured, A07015 "Alarm temperature sensor
fault" is activated and after the delay time expires, F07016 "Motor temperature sensor fault"
is output.
Temperature monitoring via ThermoClick sensor
The ThermoClick sensor responds at values ≥100 Ω. After the ThermoClick sensors has
responded, either alarm A07910 or shutdown with fault F07011 is initiated corresponding to
the setting in p0610.

The difference between the motor temperature and motor environment (P0625) must
lie within a tolerance range of approx. ± 5 °C.
7.7.4
Overcurrent protection
During vector control, the motor current remains within the torque limits set there.
During U/f control, the maximum current controller (Imax controller) protects the motor and
inverter against overload by limiting the output current.
Method of operation of Imax controller
If an overload situation occurs, the speed and stator voltage of the motor are reduced until
the current is within the permissible range. If the motor is in regenerative mode, i.e. it is
being driven by the connected machine, the Imax controller increases the speed and stator
voltage of the motor to reduce the current.
Note
The inverter load is only reduced if the motor torque decreases at lower speeds (e.g. for
fans).
In the regenerative mode, the current only decreases if the torque decreases at a higher
speed.

7.7.5
Limiting the maximum DC link voltage
How does the motor generate overvoltage?
An induction motor operates as a generator if it is driven by the connected load. A generator
converts mechanical power into electrical power. The electric power flows back into the
inverter and causes VDC in the inverter to increase.
Above a critical DC link voltage both the inverter as well as the motor will be damaged.
Before the voltage can reach critical levels, however, the inverter switches the motor off with
the fault message "DC link overvoltage".
Protecting the motor and inverter against overvoltage
The VDCmax controller prevents – as far as the application permits – the DC link voltage from
reaching critical levels.
The VDCmax controller is not suitable for applications in which the motor is permanently in the
regenerative mode, e.g. in hoisting gear or when large flywheel masses are braked. Further
information on inverter braking methods can be found in Section Braking functions of the
converter (Page 225).

Information about the inverter state (alarms, faults, actual values) can be output via inputs

Details on evaluating the inverter state via inputs and outputs are provided in Section

The evaluation of the inverter state via the communication interface is realized using the
inverter status word. Details on this are provided in the individual sections of Chapter
Configuring the fieldbus (Page 97).

System runtime
By evaluating the system runtime of the inverter, you can decide when you should replace
components subject to wear in time before they fail - such as fans, motors and gear units.
Principle of operation
The system runtime is started as soon as the Control Unit power supply is switched-on. The
system runtime stops when the Control Unit is switched off.
The system runtime comprises r2114[0] (milliseconds) and r2114[1] (days):
System runtime = r2114[1] × days + r2114[0] × milliseconds
If r2114[0] has reached a value of 86,400,000 ms (24 hours), r2114[0] is set to the value 0
and the value of r2114[1] is increased by 1.

Independent of this, you can define the units for process variables or change over to
percentage values.
Specifically, you have the following options:
● Changing over the motor standard (Page 220) IEC/NEMA (adaptation to the line supply)
● Changing over the unit system (Page 221)
● Changing over process variables for the technology controller (Page 222)
NOTICE
The motor standard, the unit system as well as the process variables can only be
changed offline.
The procedure is described in Section Changing of the units with STARTER (Page 223).

Restrictions for the unit changeover function
• The values on the rating plate of the inverter or motor cannot be displayed as
percentage values.
• Using the unit changeover function a multiple times (for example, percent → physical
unit 1 → physical unit 2 → percent) may lead to the original value being changed by
one decimal place as a result of rounding errors.
• If the unit is changed over into percent and the reference value is then changed, the
percentage values relate to the new reference value.
Example:
– For a reference speed of 1500 rpm, a fixed speed of 80% corresponds to a speed
of 1200 rpm.
– If the reference speed is changed to 3000 rpm, then the value of 80% is kept and
now means 2400 rpm.

● P0505 = 2: SI units or % relative to SI units
● P0505 = 3: US units
● P0505 = 4: US units or % relative to US units
Note
Special features
The percentage values for p0505 = 2 and for p0505 = 4 are identical. In order to perform
internal calculations and output values that are changed back over to physical variables,
however, an important factor is whether the changeover process relates to SI or US units.
In the case of variables for which changeover to % is not possible, the following applies:
p0505 = 1 ≙ p0505 = 2 and p0505 = 3 ≙ p0505 = 4.
In the case of variables whose units are identical in the SI system and US system, and
which can be displayed as a percentage, the following applies:
p0505 = 1 ≙ p0505 = 3 and p0505 = 2 ≙ p0505 = 4.

Braking functions of the converter
7.9.2.1
Comparison of electrical braking methods
Regenerative power
If an induction motor electrically brakes the connected load and the mechanical power
exceeds the electrical losses, then it operates as a generator. The motor converts
mechanical power into electrical power. Examples of applications, in which regenerative
operation briefly occurs, include:
● Grinding disk drives
● Fans
For certain drive applications, the motor can operate in the regenerative mode for longer
periods of time, e.g.:
● Centrifuges
● Hoisting gear and cranes
● Conveyor belts with downward movement of load (vertical or inclined conveyors)
Depending on the Power Modules used, SINAMICS G inverters offer the following options to
either convert the regenerative power of the motor into heat or to feed this power back into
the line supply:
● DC braking (Page 228)
for Power Modules PM230, PM240, PM250 and PM260
● Compound braking (Page 232)
for Power Module PM240
● Dynamic braking (Page 234)
for Power Module PM240
● Braking with regenerative feedback to the line (Page 236)
for Power Modules PM250 and 260

DC braking
DC braking is used for applications without regenerative feedback into the line supply, where
the motor can be more quickly braked by impressing a DC current than along a braking
ramp.
Typical applications for DC braking include:
● Centrifuges
● Saws
● Grinding machines
● Conveyor belts
Whether DC braking or ramp-down with an OFF1 command is more effective depends on
the motor properties.
Principle of operation
With DC braking, the inverter outputs an internal OFF2 command for the time that it takes to
demagnetize the motor - and then impresses the braking current for the duration of the DC
braking.

DC braking when the start speed for DC braking is fallen below
DC braking is automatically activated as soon as the motor speed falls below the start speed
for DC braking. However, the motor speed must have first exceeded the start speed for DC
braking. Once the DC braking time is complete, the inverter switches to normal operation. If
p1230 is set to 0, DC braking can also be canceled before the time defined in p1233.
DC braking when a fault occurs
If a fault occurs, where the configured response is DC braking, then the inverter first brakes
the motor along the down ramp until the start speed for DC braking is reached, and then
starts DC braking.

Functions
7.9 Application-specific functions
Activating DC braking independent of the speed using a control command
DC braking starts independent of the motor speed, as soon as the control command for
braking (e.g. via DI3: P1230 = 722.3) is issued. If the braking command is revoked, the
inverter returns to normal operation and the motor accelerates to its setpoint.
Note: The value of p1230 is displayed in r1239.11.
DC braking when the motor is switched off
If the motor is switched off with OFF1 or OFF3, the inverter first brakes the motor along the
down ramp until the start speed for DC braking is reached, and then starts DC braking. The
motor is then switched into a torque-free condition (OFF2).
Note
In the following operating modes, it is possible that the motor is still rotating after DC braking.
This is the reason that in these operating modes "Flying restart (Page 237)" must be
activated:
• DC braking when the start speed for DC braking is fallen below
• Activating DC braking independent of the speed using a control command
• DC braking when the motor is switched off
The DC braking function can only be set for induction motors.
CAUTION
DC braking converts some of the kinetic energy of the motor and load into heat in the motor
(temperature rise). The motor will overheat if the braking operation lasts too long or the
motor is braked too often.

Motor brakes with and without active compound braking
Compound braking prevents the DC link voltage increasing above a critical value. The
inverter activates compound braking depending on the DC link voltage. Above a DC link
voltage threshold (r1282), the inverters adds a DC current to the motor current. The DC
current brakes the motor and prevents an excessive increase in the DC link voltage.
Note
Compound braking is only active in conjunction with the V/f control.
Compound braking does not operate in the following cases:
• The "flying restart" function is active
• DC braking is active
• Vector control is selected

Dynamic braking
Dynamic braking is typically used in applications in which dynamic motor behavior is
required at different speeds or continuous direction changes, e.g.:
● Horizontal conveyors
● Vertical and inclined conveyors
● Hoisting gear
Principle of operation
The inverter controls the braking chopper depending on its DC link voltage. The DC link
voltage increases as soon as the inverter absorbs the regenerative power when braking the
motor. The braking chopper converts this power into heat in the braking resistor. This
therefore prevents the DC link voltage increasing above the limit value VDC link, max.

● Evaluate the braking resistor's temperature monitoring (terminals T1 and T2) such that
the motor is switched off when the resistor experiences overtemperature.
You can do this in the following two ways:
– Use a contactor to disconnect the converter from the line as soon as the temperature
monitoring responds.
– Connect the contact of the temperature monitoring function of the braking resistor with
a free digital input of your choice on the converter. Set the function of this digital input
to the OFF2 command.

WARNING
If an unsuitable braking resistor is used, this could result in a fire and severely damage the
converter.
The temperature of braking resistors increases during operation. For this reason, avoid
coming into direct contact with braking resistors. Maintain sufficient clearances around the
braking resistor and ensure that there is adequate ventilation.
Parameterizing the dynamic braking
Deactivate the VDCmax controller. The VDCmax controller is described in Section Limiting the
maximum DC link voltage (Page 216).
The dynamic braking does not have to be parameterized any further.

Braking with regenerative feedback to the line
Regenerative braking is typically used in applications where braking energy is generated
either frequently or for longer periods of time, e.g.:
● Centrifuges
● Unwinders
● Cranes and hoisting gear
Pre-requisite for regenerative braking is the Power Module PM250 or PM260.
The inverter can feed back up to 100% of its power into the line supply (referred to "High
Overload" base load, see Section Technical data, Power Modules (Page 305)).

Automatic restart and flying restart
7.9.3.1
Flying restart – switching on while the motor is running
If you switch on the motor while it is still running, then with a high degree of probability, a
fault will occur due to overcurrent (overcurrent fault F07801). Examples of applications
involving an unintentionally rotating motor directly before switching on:
● The motor rotates after a brief line interruption.
● A flow of air turns the fan impeller.
● A load with a high moment of inertia drives the motor.
After the ON command, the "flying restart" function initially synchronizes the inverter output
frequency to the motor speed and then accelerates the motor up to the setpoint.

Automatic switch-on
The automatic restart includes two different functions:
1. The inverter automatically acknowledges faults.
2. After a fault occurs or after a power failure, the inverter automatically switches-on the
motor again.
This automatic restart function is primarily used in applications where the motor is controlled
locally via the inverter's inputs. In applications with a connection to a fieldbus, the central
control should evaluate the feedback signals of the drives, specifically acknowledge faults or
switch-on the motor.
The inverter interprets the following events as power failure:
● The inverter signals fault F30003 (DC link undervoltage), as the line supply voltage of the
inverter has briefly failed.
● The inverter power supply has failed for a long enough time so that the inverter has been
switched-off.
WARNING
When the "automatic restart" function is active (p1210 > 1), the motor automatically
starts after a power failure. This is especially critical after longer power failures.
Reduce the risk of accidents in your machine or system to an acceptable level by
applying suitable measures, e.g. protective doors or covers.
Commissioning the automatic restart
● If it is possible that the motor is still rotating for a longer period of time after a power
failure or after a fault, then in addition, you must activate the "flying restart" function, see
Flying restart – switching on while the motor is running (Page 237).
● Using p1210, select the automatic restart mode that best suits your application.

The inverter automatically acknowledges faults under the following conditions:
•
p1210 = 1 or 26: always.
•
p1210 = 4 or 6: If the command to switch on the motor is available at a digital input or via the
fieldbus (ON/OFF1 command = HIGH).
•
p1210 = 14 or 16: never.
The inverter attempts to automatically switch-on the motor under the following conditions:
•
p1210 = 1: never.
•
p1210 = 4, 6, 14, 16, or 26: If the command to switch on the motor is available at a digital input
or via the fieldbus (ON/OFF1 command = HIGH).
The start attempt is successful if flying restart has been completed and the motor has been
magnetized (r0056.4 = 1) and one additional second has expired without a new fault having
occurred.

Automatic restart start attempts (factory setting: 3)
This parameter is only effective for the settings p1210 = 4, 6, 14, 16, 26.
You define the maximum number of start attempts using p1211. After each successful
fault acknowledgement, the inverter decrements its internal counter of start attempts by
1.
For p1211 = n, up to n + 1 start attempts are made. Fault F07320 is output after n + 1
unsuccessful start attempts.
The inverter sets the start attempt counter back again to the value of p1211, if one of
the following conditions is fulfilled:
p1212
•
After a successful start attempt, the time in p1213[1] has expired.
•
After fault F07320, withdraw the ON command and acknowledge the fault.
•
You change the start value p1211 or the mode p1210.
Automatic restart wait time start attempt (factory setting: 1.0 s)
This parameter is only effective for the settings p1210 = 4, 6, 26.
Examples for setting this parameter:
1. After a power failure, a certain time must elapse before the motor can be switchedon, e.g. because other machine components are not immediately ready. In this case,
set p1212 longer than the time, after which all of the fault causes have been
removed.
2. In operation, the inverter develops a fault condition. The lower you select p1212,
then the sooner the inverter attempts to switch-on the motor again.

With this monitoring function, you limit the time in which the inverter may attempt to

The monitoring function starts when a fault is identified and ends with a successful start
attempt. If the motor has not successfully started after the monitoring time has expired,
fault F07320 is signaled.
Set the monitoring time longer than the sum of the following times:
+ P1212
+ time that the inverter requires to start the motor on the fly.
+ Motor magnetizing time (p0346)
+ 1 second
You deactivate the monitoring function with p1213 = 0.
p1213[1]
Automatic restart monitoring time
to reset the fault counter (factory setting: 0 s)
This parameter is only effective for the settings p1210 = 4, 6, 14, 16, 26.
Using this monitoring time, you prevent that faults, which continually occur within a
certain time period, are automatically acknowledged each time.
The monitoring function starts with a successful start attempt and ends after the
monitoring time has expired.
If the inverter has made more than (p1211 + 1) successful start attempts within
monitoring time p1213[1], the inverter cancels the automatic restart function and signals
fault F07320. In order to switch on the motor again, you must acknowledge the fault and
issue a new ON command.
Additional information is provided in the parameter list of the List Manual.
Advanced settings
If you with to suppress the automatic restart function for certain faults, then you must enter
the appropriate fault numbers in p1206[0 … 9].
Example: P1206[0] = 07331 ⇒ No restart for fault F07331.
Suppressing the automatic restart only functions for the setting p1210 = 6, 16 or 26.
WARNING
In the case of communication via the field bus interface, the motor restarts with the setting
p1210 = 6 even if the communication link is interrupted. This means that the motor cannot
be stopped via the open-loop control. To avoid this dangerous situation, you must enter the
fault code of the communications error in parameter p1206.
Example: A communication failure via PROFIBUS is signaled using fault code F01910. You
should therefore set p1206[n] = 1910 (n = 0 … 9).

Load torque monitoring (system protection)
In many applications, it is advisable to monitor the motor torque:
● Applications where the load speed can be indirectly monitored by means of the load
torque. For example, in fans and conveyor belts too low a torque indicates that the drive
belt is torn.
● Applications that are to be protected against overload or locking (e.g. extruders or
mixers).
● Applications in which no-load operation of the motor represents an impermissible
situation (e.g. pumps).
Load torque monitoring functions
The converter monitors the torque of the motor in different ways:
1. No-load monitoring:
The converter generates a message if the motor torque is too low.
2. Blocking protection:
The converter generates a message if the motor speed cannot match the speed setpoint
despite maximum torque.
3. Stall protection:
The converter generates a message if the converter control has lost the orientation of the
motor.
4. Speed-dependent torque monitoring
The converter measures the actual torque and compares it with a parameterized
speed/torque characteristic.

Real time clock (RTC)
The real time clock is the basis for time-dependent process controls, e.g.:
● To reduce the temperature of a heating control during the night
● Increase the pressure of a water supply at certain times during the day
Real time clock: Format and commissioning
The real time clock starts as soon as the Control Unit power supply is switched on for the
first time. The real time clock comprises the clock time in a 24 hour format and the date in
the "day, month, year" format.
After a Control Unit power supply interruption, the real time clock continues to run for approx.
five days.
If you wish to use the real time clock, you must set the time and date once when
commissioning. If you restore the inverter factory setting, the real time clock parameters are
not reset.

Accept the real time clock in the alarm and fault buffer
Using the real time clock, you can track the sequence of alarms and faults over time. When
an appropriate message occurs, the real time clock is converted into the UTC time format
(Universal Time Coordinated):
Date, time ⇒ 01.01.1970, 0:00 + d (days) + m (milliseconds)
The number "d" of the days and the number "m" of milliseconds is transferred into the alarm
and fault times of the alarm or fault buffer, see Chapter Alarms, faults and system messages
(Page 285).
Converting UTC into RTC
An RTC can again be calculated from the UTC. Proceed as follows to calculate a date and
time from a fault or alarm time saved in the UTC format:
1. Calculate the number of seconds of UTC:
Number of seconds = ms / 1000 + days × 86400
2. In the Internet, you will find programs to convert from UTC into RTC, e.g.:
UTC to RTC (http://unixtime-converter.com/)
3. Enter the number of seconds in the corresponding screen and start the calculation.
Example:
Saved as alarm time in the alarm buffer:
r2123[0] = 2345 [ms]
r2145[0] = 14580 [days]
Number of seconds = 2345 / 1000 + 14580 × 86400 = 1259712002
Converting this number of seconds in RTC provides the date: 02.12.2009, 01:00:02.

● Switching a process control from weekday to weekend.
Principle of operation of the time switch (DTC)
The inverter has three independent parameterizable time switches. Using BICO technology,

Parameterizing the time switch
● Enable parameterization of the DTC: p8409 = 0.
As long as DTC parameterization is enabled, the inverter keeps the output of all three
DTC (r84x3, x = 1, 2, 3) on LOW.
● Parameterize the activation of the weekdays; the switching on and off times.
● Enable the setting: p8409 = 1.

Temperature sensing using temperature-dependent resistors
Analog input AI 2
Analog input AI 2 can be used as a current input or resistance input for a temperature
sensor. Both the DIP switch and parameter p0756.2 must be set accordingly for this
purpose.
● P0756.2 = 2 or 3 -> options for setting as current input
● P0756.2 = 6, 7 or 8 -> options for setting as temperature sensor
Analog input AI 3
Analog input AI 3 is designed as a resistance input for a temperature sensor.
Setting options:
● P0756.3 = 6, 7 or 8 -> options for setting as temperature sensor
Permissible temperature sensors
The temperature-dependent PT1000 or NI1000 resistors can be used as sensors. The
values of these sensors are supplied via analog input AI 2 or AI 3 (p2264 = 756.2 or 756.3)
as actual values for the technology controller.
The connection is established at AI 2 (terminals 50, 51) or AI 3 (terminals 52, 53).
Measuring ranges and alarm thresholds for NI1000
The measuring range of the NI1000 sensors extends from – 88 °C … 165 °C. For values
outside this range, the inverter outputs alarm A03520 "Temperature sensor fault". The fault
type is displayed in r2124.
Measuring ranges and alarm thresholds for PT1000
The measuring range of the PT1000 sensors extends from – 88 °C … 240 °C. For values
outside this range, the inverter outputs alarm A03520 "Temperature sensor fault". The fault
type is displayed in r2124.

Essential service mode
The Essential Service Mode (ESM) function ensures that when required, the motor is
operated for as long as possible so that, for example, smoke gases can be extracted or
people affected by a fire can escape.
Application example
In order to improve air circulation in stairwells, frequently, a slight underpressure is
generated using ventilation control. With this control, a fire would mean that smoke gases
enter into the stairwell. This would then mean that the stairway would be blocked as escape
or evacuation route.
Using the Essential Service Mode function, the ventilation switches over to control an
overpressure. This prevents the propagation of smoke gases in the stairwell, thereby
keeping the stairs free as an escape route.
Activating the essential service mode function
The essential service mode is activated by interconnecting p3880 with a digital input of your
choice. Example: If you wish to activate the essential service mode with the digital input, set
p3880 = 722.3.
Note
Command source for the essential service mode
We recommend that the digital input for the essential service mode is not logically combined
with any other functions.
• The setting of the source for the essential service mode via p3880 is always referred to
the data set that is currently active.
• The essential service mode can only be switched on precisely from one source.
The last setpoint recognized is taken as the emergency setpoint in the factory setting. You
can use p3881 to define another value:
● P3881 = 0: Last recognized setpoint (factory setting)
● P3881 = 1: Fixed setpoint 15
● P3881 = 2: Analog setpoint
● P3881 = 3: Fieldbus
● P3881 = 4: Technology controller
If you specify the emergency setpoint via the analog setpoint, fieldbus or technology
controller, you must ensure the appropriate monitoring so that an alternative setpoint can be
used in the event of failure.
Possible forms of monitoring for the different setpoint sources:
● Analog setpoint: Using F03505
● Fieldbus status in r2043
● Technology controller r2349

Functions
7.9 Application-specific functions
You will find additional details on this in the List Manual in the function diagrams for essential
service mode, setpoint channel and technology controller.
When in the factory setting, if the setpoint is lost, the drive continues using the last
recognized setpoint. p3882 can be used to switch to the following values:
● P3882 = 0: Last recognized setpoint (factory setting)
● p3882 = 1: Fixed speed setpoint which is defined in p1015
● p3882 = 2: Maximum speed (value of p1082)
Note
Technology controller as setpoint source for the emergency operation setpoint
For the technology controller to be able to specify the emergency setpoint, it must be
activated (p2200 = 1) and set as the main setpoint (p2251 = 0).
Direction of rotation in the essential service mode
● Emergency setpoint using p3881 = 0, 1, 2, 3
Depending on your system, you may have to invert the setpoint locally for the essential
service mode. The customer can therefore use p3883 to determine the direction of
rotation of the emergency setpoint. To do this, p3883 must be linked with a free digital
input, e.g. p3883 = r722.12.
– p3883 = 0 -> normal emergency direction of rotation,
– p3883 = 1 -> inverted emergency direction of rotation.
● Emergency setpoint using p3881 = 4
If the emergency setpoint is specified using the technology controller, it is depicted using
variables within the process and depends on these. Inversion using a digital input is
therefore locked in such cases and must be implemented in the technology controller.
Bypass operation in the essential service mode
● If the motor is running in bypass operation when the emergency happens, the user must
query the "Bypass control/status word" (r1261) and make an appropriate interconnection
to ensure that the motor is switched to the inverter and continues to run with the
emergency setpoint.
● If the inverter has failed in the essential service mode because of an internal fault and if it
cannot be switched back on using the automatic restart function, the user can
interconnect bit 7 of the status word for the automatic restart (r1214.7) with p1266 to
operate the motor directly on line. You will find additional information about bypass
operation in section Bypass (Page 265).

Special features of the essential service mode
● The automatic restart function is internally activated – independent of the setting of p1210
– as soon as the essential service mode kicks in. This results in the inverter being
restarted if a pulse inhibit (OFF2) occurs due to an internal fault.
● In the essential service mode, inverter shutdown due to faults is suppressed, with the
exception of faults that would lead to the destruction of the inverter. You will find a a list of
these faults in Section Essential service mode (Page 252).
● The essential service mode is triggered by a continuous signal (level-triggered) using the
digital input which was defined in p3880 as the source for the essential service mode.
● In the essential service mode, the motor can only be stopped if the line voltage is
switched off.
● If the essential service mode is deactivated, the inverter reverts to normal operation and
its behavior depends on the pending commands and setpoints.
● The essential service mode has priority over other operating modes
NOTICE
Loss of warranty for an inverter in the essential service mode
In the case of the essential service mode, the customer can no longer lodge any claims
for warranty. The essential service mode and the faults that arise while in the essential
service mode are logged in a password protected memory and can be read by the repair
center.
Refer to parameters p3880 … r3889 for more information on the essential service mode.
Note
Other preconditions for the essential service mode
In order to operate the inverter in the emergency service mode, the appropriate degrees of
protection and connection and installation guidelines applicable to the system should be
observed. You will find details of this in the Australian Standard: AS/NZS 1668.1:1998.

Multi-zone control
Multi-zone control is used to control quantities such as pressure or temperature via the

Control variants for multi-zone control
There are three control variants for multi-zone control, which are selected via p31021:
● One setpoint and one, two or three actual values
The actual value for the control can be calculated as mean value, maximum value or

– Average value: The deviation from the setpoint of the average value of two or three
actual values is controlled.
– Minimum value: The deviation from the setpoint of the smallest actual value is
controlled.
– Maximum value: The deviation from the setpoint of the highest actual value is
controlled.
● Two setpoint/actual value pairs as maximum value control (cooling)
The maximum value control compares two setpoints/actual value pairs and controls the
actual value which has the largest deviation upwards from its associated setpoint. No
control takes place if both actual values lie below their setpoints.
In order to avoid frequent changeover, the inverter only switches over if the deviation of
the controlled setpoint-actual value pair is more than two percent lower than the deviation
of the uncontrolled value pair.
● Two setpoint/actual value pairs as minimum value control (heating)
The minimum value control compares two setpoints/actual value pairs and controls the
actual value, which has the highest deviation downwards from its associated setpoint. No
control takes place if both actual values lie above their setpoints.
In order to avoid frequent changeover, the inverter only switches over if the deviation of
the controlled setpoint-actual value pair is more than two percent lower than the deviation
of the uncontrolled value pair.

Cascade control
The cascade control function is used in applications that require between one and four
motors to be run at the same time depending on load, so that e.g. highly variable pressure
ratios or flow volumes can be corrected.
Cascade control consists of the speed-controlled main drive and up to three other drives that
are switched-on or switched-off via contactors or motor starters, either in a fixed
arrangement or dependent on the operating hours.
The PID deviation serves as the input signal for activating the other motors. The contactors
or motor starters are switched by the inverter's digital outputs.
Note
Technology controller as main setpoint
For cascade control, the main setpoint must be entered via the technology controller (p2251
= 0, p2200 = 1).
Operating principle
● Switching-in external motors
If the main drive is run at maximum speed and the deviation on the technology controller
input continues to increase, the control also switches the external motors on the line. At
the same time, the main drive is ramped down to the switch-on/switch-off speed (p2378)
to keep the total output power as constant as possible. The technology controller is
deactivated while ramping down to the switch-on/switch-off speed.
● Shutting down external motors
If the main drive is running at minimum speed and the deviation on the technology
controller input continues to decrease, the control switches external motors M1 to M3 off
the line. The main drive is simultaneously ramped-up to the switch-on/switch-off speed to
keep the total output power as constant as possible.

Functions
7.9 Application-specific functions
To avoid frequent activation/deactivation of the uncontrolled motors, a time can be specified
in p2377 which must have elapsed before a further motor can be activated/deactivated. After
the time set in p2377 has elapsed, a further motor will be activated immediately if the PID
deviation is greater than the value set in p2376. If, after p2377 has elapsed, the PID
deviation is smaller than p2376 but greater than p2373, the timer p2374 is started before the
uncontrolled motor is activated.
The motors are deactivated in the same way.

Bypass
If the bypass is controlled by a higher-level
control, the control must lock the contactors
so they cannot switch on at the same time.
If controlled by inverter, the digital outputs are
used to activate two contactors via which the
motor is powered. The inverter is provided
with contactor position feedback via the digital
inputs. This is evaluated. If using direct
connection logic (high level = ON), both
contactors should be NO contacts.

NOTICE
Bypass operation in the essential service mode
The special features for bypass operation in the essential service mode are described in
Section Essential service mode (Page 252).
Changeover operation between line and inverter operation
At changeover to line operation, contactor K1 is opened (after the inverter pulses have been
inhibited). The system then waits for the motor de-excitation time to elapse, after which
contactor K2 is closed, connecting the motor directly to the line supply.
When the motor is switched to the line supply, an equalizing current flows that must be taken
into account when the protective equipment is selected and dimensioned.

Functions
7.9 Application-specific functions
When changing over to inverter operation, initially contactor K2 must be opened and after
the de-excitation time, contactor K1 is closed. The inverter then captures the rotating motor
and the motor is operated on the inverter.
Bypass function when activating via a control signal (p1267.0 = 1)
The status of the bypass contactors is evaluated when the inverter is switched on. If the
automatic restart function is active (p1210 = 4) and an ON command (r0054.0 = 1) as well as
the bypass signal (p1266 = 1) are still present at power up, then after power up, the inverter
goes into the "ready and bypass" state (r899.0 = 1 and r0046.25 = 1) and the motor
continues to run directly connected to the line supply.

General properties of the bypass function
● y
● Contactors K1 and K2 must be mutually interlocked so that they cannot close at the same
time.
Shutdown behavior in bypass operation
● If the motor is in the bypass mode, it cannot be shutdown with OFF 1. The motor coasts
down after an OFF2 or OFF3.
● If the motor is running in the bypass mode and the inverter is disconnected from the line
supply, then also the bypass contactor does not receive control signals from the inverter
and the motor coasts down. If the motor is to continue running once the inverter is
switched off, the signal for the bypass contactor must therefore come from the higherlevel control.
Temperature monitoring and overload protection in the bypass mode
● If the motor is running in the bypass mode, while the inverter is in the "ready and bypass"
state (r899.0 = 1 and r0046.25 = 1), then the motor temperature monitoring via the
temperature sensor is active.
● If the motor is running in the bypass mode, while the inverter is in the "ready and bypass"
state (r899.0 = 1 and r0046.25 = 1), then the overload protection for the motor must be
realized on the plant or system side.

Energy-saving mode
The energy-saving mode is mainly used for pumps and fans. Typical applications include
pressure and temperature controls.
In the energy-saving mode, the inverter stops and starts the motor depending on the system
conditions. The energy-saving mode can be activated via the technology controller (without
external commands via terminals or bus interface) and via an external setpoint input.
The energy-saving mode offers the advantages of energy saving, lowering mechanical wear
and reduced noise.
Note
In the energy-saving mode, if the setpoint is to be entered from the motorized potentiometer
or from the motorized potentiometer of the technology controller, you must set p1030.4 or
p2230.4 = 1.
NOTICE
After the inverter has been powered up, the motor goes into the energy-saving mode if the
energy-saving mode start speed has still not been reached after the highest value from
p1120 (ramp-up time), p2391 (energy-saving mode delay time) and 20 s have expired.
Operating principle
The energy-saving mode starts as soon as the motor speed drops below the energy-saving
mode start speed. However, the motor is only switched off after an adjustable time has
expired. If, during this time, the speed setpoint increases above the energy-saving mode
start speed due to pressure or temperature changes, the energy-saving mode is exited and
the inverter goes into normal operation.

7.9 Application-specific functions
In the energy-saving mode, the motor is shut down; however, the speed setpoint and/or the
technology controller deviation are/is monitored.
● For an external setpoint input (without technology controller) the speed setpoint is
monitored and the motor is switched-on again as soon as the setpoint increases above
the restart speed. The restart speed is calculated as follows: Restart
speed = P1080 + p2390 + p2393.
In the factory setting, the positive speed setpoint is monitored, i.e. the motor is switched
on as soon as the setpoint exceeds the restart speed.
If the negative speed setpoint is also to be monitored, the value of the setpoint must be
monitored. This can be set using p1110 = 0.
Additional setting options are described in the parameter list, in function diagrams 3030
and 3040 as well as in the associated parameter descriptions.
● When the setpoint is entered from the technology controller, the technology controller
deviation (r2273) is monitoredand the motor is switched-on if the deviation of the
technology controller exceeds the energy-saving mode restart value (2392).
In the factory setting, only the positive deviation of the technology controller is monitored,
i.e. the motor is switched on as soon as the technology controller deviation is greater than
the energy-saving mode restart value (p2392).
If the motor should also switch back on for negative technology controller deviation, the
value of the deviation must be monitored.
In this case p2298 = 2292 must be set. The percentage value for the minimum limit can
be specified in p2292.
Additional setting options are provided in the parameter list in function diagram 7958 and
in the associated parameter descriptions.
In order to prevent frequent starts and stops, the speed may be boosted for a short time
before shutdown (boost). This function can be disabled by setting the boost time (p2394) to
0.
To avoid tank deposits, particularly where liquids are present, it is possible to exit the
energy-saving mode after an adjustable time (p2396) has expired and switch to normal
operation.
The parameter settings required for the respective variant can be found in the following

Logical and arithmetic functions using function blocks
Additional signal interconnections in the inverter can be established by means of free
function blocks. Every digital and analog signal available via BICO technology can be routed
to the appropriate inputs of the free function blocks. The outputs of the free function blocks
are also interconnected to other functions using BICO technology.
Among others, the following free function blocks are available:
● Logic modules AND, OR, XOR, NOT
● Arithmetic blocks ADD, SUB, MUL, DIV, AVA (device for forming absolute values), NCM
(numeric comparator), PLI (polyline)
● Time modules MFP (pulse generator), PCL (pulse shortening), PDE (ON delay), PDF
(OFF delay), PST (pulse stretching)
● Memories: RSR (RS flip-flop), DSR (D flip-flop)
● Switches NSW (numeric change-over switch) BSW (binary change-over switch)
● Controllers LIM (limiter), PT1 (smoothing element), INT (integrator), DIF (differentiating
element)
● Limit value monitoring LVM
You will find an overview of all of the free function blocks and their parameters in the List
Manual, in Chapter "Function diagrams" in the section "Free function blocks" (function
diagrams 7210 ff).
Activating the free blocks
None of the free function blocks in the inverter are used in the factory setting. In order to be
able to use a free function block, you must perform the following steps:
● In the parameter list, select the function block from the function diagrams - there you will
find all of the parameters that you require to interconnect the block
● Assign the block to a runtime group
● Define the run sequence within the runtime group - this is only required if you have
assigned several blocks to the same runtime group.
● Interconnect the block's inputs and outputs with the corresponding signals on the inverter.
The runtime groups are calculated at different intervals (time slices). Please refer to the
following table to see which free function blocks can be assigned to which time slices.

Analog signal scaling
If you interconnect a physical quantity, e.g. speed or voltage to the input of a free function
block using BICO technology, then the signal is automatically scaled to a value of 1. The
analog output signals of the free function blocks are also available as scaled quantities (0 ≙
0 %, 1≙ 100 %).
As soon as you have interconnected the scaled output signal of a free function block to
functions, which require physical input quantities - e.g. the signal source of the upper torque
limit (p1522) - then the signal is automatically converted into the physical quantity.
The quantities with their associated scaling parameters are listed in the following:
• Speeds

Scaling examples
● Speed:
Reference speed p2000 = 3000 rpm, actual speed 2100 rpm. As a consequence, the
following applies to the scaled input quantity: 2,100 / 3,000 = 0.7.
● Temperature:
Reference quantity is 100 °C. For an actual temperature of 120 °C, the input value is
obtained from 120 °C / 100 °C = 1.2.
Note
Limits within the function blocks should be entered as scaled values. The scaled value
can be calculated as follows using the reference parameter: Scaled limit value = physical
limit value / value of the reference parameter.
The assignment to reference parameters is provided in the parameter list in the individual
parameter descriptions.
Example: Logic combination of two digital inputs
You want to switch on the motor via digital input 0 and also via digital input 1:
1. Activate a free OR block by assigning it to a runtime group, and define the run sequence.
2. Interconnect the status signals of the two digital inputs DI 0 and DI 1 via BICO to the two
inputs of the OR block.
3. Finally, interconnect the OR block output with the internal ON command (P0840).

Switchover between different settings
In several applications, the inverter must be able to be operated with different settings.
Example:
You connect different motors to one inverter. Depending on the particular motor, the inverter
must operate with the associated motor data and the appropriate ramp-function generator.
Drive data sets (DDS)
Your can parameterize several inverter functions differently and then switch over between
the different settings.
The associated parameters are indexed (index 0, 1, 2 or 3). Using control commands select
one of the four indices and therefore one of the four saved settings.
The settings in the inverter with the same index are known as drive data set.

If you have saved the settings of your converter on another
medium, e.g. on an operator panel or on a PC, then after
the replacement, the settings must be loaded into the
converter.
WARNING
In all other cases, you must recommission the drive.

Replacing the Control Unit
WARNING
230 V AC can be connected via the relay outputs DO 0 and DO 2 of the Control Unit. These
terminals can carry 230 V AC independent of the voltage condition of the Power Module.
Therefore please observe appropriate safety measures when working on the inverter.
After commissioning has been completed, we recommend that you back up your settings on
an external storage medium, e.g.: on a memory card or the operator panel.
If you do not back up your data, you have to recommission the drive when you replace the
Control Unit.
Procedure for replacing a Control Unit with a memory card
● Disconnect the line voltage of the Power Module and (if installed) the external 24 V
supply or the voltage for the relay outputs DO 0 and DO 2 of the Control Unit.
● Remove the signal cables of the Control Unit.
● Remove the defective CU from the Power Module.
● Plug the new CU on to the Power Module. The new CU must have the same order
number and the same or a higher firmware version as the CU that was replaced.
● Remove the memory card from the old Control Unit and insert it in the new Control Unit.
● Reconnect the signal cables of the Control Unit.
● Connect up the line voltage again.
● The converter adopts the settings from the memory card, saves them (protected against
power failure) in its internal parameter memory, and switches to "ready to start" state.
● Switch on the motor and check the function of the drive.

● Remove the signal cables of the Control Unit.
● Remove the defective CU from the Power Module.
● Plug the new CU on to the Power Module.
● Reconnect the signal cables of the Control Unit.
● Connect up the line voltage again.
● The converter goes into the "ready-to-switch-on" state.
● If you have backed up your settings:
– Load the settings from the operator panel or via STARTER into the converter.
– For converters of the same type and the same firmware version, you can now switchon the motor. Check the function of the drive
– For different converter types, then the converter outputs alarm A01028. This alarm
indicates that the settings that have been loaded are not compatible with the
converter. In this case, clear the alarm with p0971 = 1 and recommission the drive.
● If you have not backed up your settings, then you must recommission the drive.

The converter has the following diagnostic types:
● LED
The LED at the front of the converter immediately informs you about the most important
converter states right at the converter.
● Alarms and faults
The converter signals alarms and faults via the fieldbus, the terminal strip (when
appropriately set), on a connected operator panel or STARTER.
Alarms and faults have a unique number.
If the converter no longer responds
Due to faulty parameter settings, e.g. by loading a defective file from the memory card, the
converter can adopt the following condition:
● The motor is switched off.
● You cannot communicate with the converter, either via the Operator Panel or other
interfaces.
In this event proceed as follows:
● Remove the memory card if one is inserted in the converter.
● Repeat the power on reset until the converter outputs fault F01018:
– Switch off the converter supply voltage.
– Wait until all LEDs on the converter go dark. Now switch on the converter supply
voltage again.
● If the converter signals fault F01018, repeat the power on reset one more time.
● The converter must now have been restored to its factory settings.

Alarms
Alarms have the following properties:
● They do not have a direct effect in the inverter and disappear once the cause has been
removed
● They do not need have to be acknowledged
● They are signaled as follows
– Status display via bit 7 in status word 1 (r0052)
– at the Operator Panel with a Axxxxx
– via STARTER, if you click on TAB
at the bottom left of the STARTER screen
In order to pinpoint the cause of an alarm, there is a unique alarm code and also a value for
each alarm.
Alarm buffer
For each incoming alarm, the inverter saves the alarm, alarm value and the time that the
alarm was received.

Saving the first alarm in the alarm buffer
r2124 and r2134 contain the alarm value - important for diagnostics - as "fixed point" or
"floating point" number.
The alarm times are displayed in r2145 and r2146 (in complete days) as well as in r2123 and
r2125 (in milliseconds referred to the day of the alarm).
The inverter uses an internal time calculation to save the alarm times. More information on
the internal time calculation can be found in Chapter Real time clock (RTC) (Page 247).
As soon as the alarm has been removed, the inverter writes the associated instant in time
into parameters r2125 and r2146. The alarm remains in the alarm buffer even if the alarm
has been removed.
If an additional alarm is received, then this is also saved. The first alarm is still saved. The
alarms that have occurred are counted in p2111.

Emptying the alarm buffer: Alarm history
The alarm history traces up to 56 alarms.
The alarm history only takes alarms that have been removed from the alarm buffer. If the
alarm buffer is completely filled - and an additional alarm occurs - then the inverter shifts all
alarms that have been removed from the alarm buffer into the alarm history. In the alarm
history, alarms are also sorted according to the "alarm time received", however, when
compared to the alarm buffer, in the inverse sequence:
● the youngest alarm is in index 8
● the second youngest alarm is in index 9
● etc.

Faults
A fault displays a severe fault during operation of the inverter.
The inverter signals a fault as follows:
● at the Operator Panel with Fxxxxx
● at the Control Unit using the red LED RDY
● in bit 3 of the status word 1 (r0052)
● via STARTER
To delete a fault message, you need to remedy the cause of the fault and acknowledge the
fault.
Every fault has a clear fault code and also a fault value. You need this information to
determine the cause of the fault.
Fault buffer of actual values
For each fault received, the inverter saves the fault code, fault value and the time of the fault.

Saving the first fault in the fault buffer
r0949 and r2133 contain the fault value - important for diagnostics - as "fixed point" or
"floating point" number.
The "fault time received" is in parameter r2130 (in complete days) as well as in parameter
r0948 (in milliseconds referred to the day of the fault). The "fault time removed" is written into
parameters r2109 and r2136 when the fault has been acknowledged.
The inverter uses its internal time calculation to save the fault times. More information on the
internal time calculation can be found in Chapter Real time clock (RTC) (Page 247).
If an additional fault occurs before the first fault has been acknowledged, then this is also
saved. The first alarm remains saved. The fault cases that have occurred are counted in
p0952. A fault case can contain one or several faults.

Complete fault buffer
Fault acknowledgement
In most cases, you have the following options to acknowledge a fault:
● Switch-off the inverter power supply and switch-on again.
● Press the acknowledgement button on the operator panel
● Acknowledgement signal at digital input 2
● Acknowledgement signal in bit 7 of control word 1 (r0054) for Control Units with fieldbus
interface
Faults that are triggered by monitoring of hardware and firmware inside the inverter can only
be acknowledged by switching off and on again. You will find a note about this restricted
option to acknowledge faults in the fault list of the List Manual.
Emptying the fault buffer: Fault history
The fault history can contain up to 56 faults.
The fault acknowledgement has no effect as long as none of the fault causes of the fault
buffer have been removed. If at least one of the faults in the fault buffer has been removed
(the cause of the fault has been removed) and you acknowledge the faults, then the
following happens:
1. The inverter accepts all faults from the fault buffer in the first eight memory locations of
the fault history (indices 8 ... 15).
2. The inverter deletes the faults that have been removed from the fault buffer.
3. The inverter writes the time of acknowledgement of the faults that have been removed
into parameters r2136 and r2109 (fault time removed).

Fault history after acknowledging the faults
After acknowledgement, the faults that have not been removed are located in the fault buffer
as well as in the fault history. For these faults, the "fault time coming" remains unchanged
and the "fault time removed" remains empty.
If less than eight faults were shifted or copied into the fault history, the memory locations with
the higher indices remain empty.
The inverters shifts the values previously saved in the fault history each by eight indices.
Faults, which were saved in indices 56 … 63 before the acknowledgement, are deleted.
Deleting the fault history
If you wish to delete all faults from the fault history, set parameter p0952 to zero.

● Does p0010 = 0?
If not, the inverter is e.g. still in a commissioning state.
● Is the inverter reporting the "ready to start" status (r0052.0 = 1)?
● Is the inverter missing enabling (r0046)?
● Are the command and setpoint sources for the inverter (p0015) correctly parameterized?
In other words, where is the inverter getting its speed setpoint and commands from
(fieldbus or analog input)?
● Do the motor and inverter match?

Creating a STEP 7 project
PROFIBUS communication between the inverter and a SIMATIC control is configured using
the SIMATIC STEP 7 and HW Config software tools.
Procedure
● Create a new STEP 7 project and assign a project name, e.g. "G120_in_S7". Add an S7
300 CPU.
Figure A-1
Inserting a SIMATIC 300 station into a STEP 7 project
● Select the SIMATIC 300 station in your project and open the hardware configuration (HW
Config) by double clicking on "Hardware".
● Add an S7 300 mounting rail to your project by dragging and dropping it from the
"SIMATIC 300" hardware catalog. Locate a power supply at slot 1 of the mounting rail
and a CPU 315-2 DP at slot 2.

Configuring communications to a SIMATIC control
The inverter can be connected to a SIMATIC control in two ways:
1. Using the inverter GSD
2. Using the STEP 7 object manager
This somewhat more user-friendly method is only available for S7 controls and installed
Drive ES Basic (see Section Modularity of the converter system (Page 21)).
The following section describes how to configure the inverter using the GSD.

Appendix
A.1 Application examples
A.1.1.5
Inserting the inverter into the STEP 7 project
● Install the GSD of the converter in STEP 7 using HW Config (menu "Options - Install GSD
files").
After the GSD has been installed, the converter appears under "PROFIBUS DP - additional
field devices" in the hardware catalog of HW Config.
● Drag and drop the converter into the PROFIBUS network. Enter the PROFIBUS address
set at the converter in HW Config.
● Insert the required telegram type from the HW catalog by "dragging and dropping" into
slot 1 of the converter.
You can find more detailed information on the telegram types in Chapter Cyclic
communication (Page 101).
Sequence when assigning the slots
1. PKW channel (if one is used)
2. Standard, SIEMENS or free telegram (if one is used)
3. Slave-to-slave module
If you do not use one or several of the modules 1 or 2, configure the remaining modules
starting with the 1st slot.

Appendix
A.1 Application examples
Note regarding the universal module
It is not permissible to configure the universal module with the following properties:
● PZD length 4/4 words
● Consistent over the complete length
With these properties, the universal module has the same DP identifier (4AX) as the "PKW
channel 4 words" and is therefore identified as such by the higher-level control. As a
consequence, the control does not establish cyclic communication with the inverter.
Remedy: Change the length to 8/8 bytes in the properties of the DP slave. As an alternative,
you can also change the consistency to "unit".
Final steps
● Save and compile the project in STEP 7.
● Establish an online connection between your PC and the S7 CPU and download the
project data to the S7 CPU.
● In the inverter, select the telegram type, which you configured in STEP 7, using
parameter P0922.
The inverter is now connected to the S7 CPU. This therefore defines the communication
interface between the CPU and the inverter. An example of how you can supply this
interface with data can be found in the next section.

In this example, inputs E0.0 and E0.6 are linked
to the -bit ON/OFF1 or to the "acknowledge fault"
bit of STW 1.
Control word 1 contains the numerical value
047E hex. The bits of control word 1 are listed in
the following table.

The control and inverter communicate via
standard telegram 1. The control specifies
control word 1 (STW1) and the speed setpoint,
while the inverter responds with status word 1
(ZSW1) and its actual speed.
The hexadecimal numeric value 2500 specifies
the setpoint frequency of the inverter. The
maximum frequency is the hexadecimal value
4000 (also see Configuring the fieldbus
(Page 97)).
The control cyclically writes the process data to
logical address 256 of the inverter. The inverter
also writes its process data to logical
address 256. You define the address area in HW
Config, seeInserting the inverter into the STEP 7
project (Page 326).

Communication with the higher-level control and between the drives with slave-to-slave communication
Settings in the control
In HW Config in drive 2 (Subscriber),
insert a slave-to-slave communication
object, e.g. "Slave-to-slave, PZD2".
With a double-click, open the dialog
box to make additional settings for the
slave-to-slave communication.

Appendix
A.1 Application examples
① Activate the tab "Address
configuration".
② Select line 1.
③ Open the dialog box in which you
define the Publisher and the address
area to be transferred.
① Select DX for direct data exchange
② Select the PROFIBUS address of
drive 1 (publisher).
③ In the address field, select the start
address specifying the data area to be
received from drive 1. In the example,
these are the status word 1 (PZD1)
and the speed actual value with the
start address 256.
Close both screen forms with OK. You have now defined the value range for slave-to-slave
communication.
In the slave-to-slave communication, drive 2 receives the sent data and writes this into the
next available words, in this case, PZD3 and PZD4.
Settings in drive 2 (subscriber)
Drive 2 is preset in such a way that it receives its setpoint from the higher-level control. In
order that drive 2 accepts the actual value sent from drive 1 as setpoint, you must set the
following:
● In drive 2 ,set the PROFIdrive telegram selection to "Free telegram configuration with
BICO" (p0922 = 999).
● In drive 2, set the source of the main setpoint to p1070 = 2050.3.
