Objective of the application
This application is based on the technological interaction between the SINAMICS
drive system and the DCC programming language and a SIMATIC S7 PLC.
In order to show this as simply and as practically as possible, a technological
function, frequently used in machines is used in a simple example with HMI (winCC
flexible). This means that the application can also be used as presentation model.
Core contents of this application
The following core issues are discussed in this application:
How the various components interact and operate with one another
Which technological function is used
The advantages that this solution offers
Copyright Siemens AG 2009 All rights reserved
Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
How the technological function is programmed or parameterized
How the example can be used as presentation/demonstration system
Scope of the document
This application does not include:
Automatic control of the traversing arm via SIMATIC S7. The user must
integrate this application into his automation solution.
The traversing arm runs in velocity synchronism with the winder. If there is a
requirement regarding angular offset control - and therefore a rigid synchronous
angular relationship - then we recommend the “Traversing arm in SIMOTION“
application.
Simple traversing arms can be very quickly implemented using the basic
positioning mode ”traversing blocks”. However, in this case, many of the
subsequently described functions will only be possible with certain restrictions.
It is assumed that the reader has basic knowledge about these subjects and topics.

Basic information
1.1
Prerequisites
1.1.1
Target group
The standard application is intended for all programmers and users that which to
quickly and simply implement traversing arm functionality using SINAMICS.
1.1.2
Technical environment
This standard application can be used, unchanged, in conjunction with a SIMATIC
S7 and a SINAMICS S120 demonstration case.
1.2
Objective and purpose of this application
1.2.1
Task description
The standard traversing arm application in SINAMICS was developed with the
objective to create a flexible solution for traversing arm applications; whereby the
essential and relevant data for the traversing arm process can be entered using
input values and changed during operation (hot changes).
This means that by specifically entering the input values, the traversing arm profile
- and therefore the stability of the winding structure can be influenced in a specific
fashion. Due to the fact that the software structure is open, when required, it is also
possible to modify the application. Using the appropriate equipment, this
application allows a wide range of different materials to be traversed with a specific
profile (e.g. textile fibers, wires, …). It is ensured that the motor, which drives the
traversing arm equipment, precisely follows the input values. In practice, the quality
of the traversing motion depends on the mechanical design of the traversing arm
unit and the properties and characteristics of the material that is being wound using
the traversing arm.
Typically, the traversing arm drive operates in conjunction with a winder that
supplies the leading (master) value for the traversing arm.
1.2.2
Problem solution using the standard application
A DCC program is the core function of this standard application: The traversing
arm is implemented in the DCC program and can be simply parameterized.
Only the traversing arm interface has to be processed and the input/output
parameters appropriately interconnected in the user program in the SIMATIC S7.

Advantages of the standard application
The use of the standard “Traversing arm" application offers users the following
advantages:
The program can be quickly generated
By using the standard “Traversing arm” application, it is possible to quickly and
simply implement extensive traversing arm functionality when generating the
program with SIMATIC S7. The core function can be integrated into the user
program by simply parameterizing it. The necessary configuring steps will be
explained in this description of the standard application.
Possibility of adapting the user program
The standard “Traversing arm” application is included with the DCC chart in a form
that has comments. This means that this core function can be quickly and simply
expanded by users to include their own functions.

Principle of operation of the application
1.4.1
Schematic representation
A wound roll is shown as example in the following diagram.
As can be seen from the diagram, the profile of the roll being wound can be
defined using the following quantities: Waiting angle, acceleration distance,
winding step and winding width. The v-t diagram of a traversing motion is shown in
the diagram below.

Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
Fig. 1-1
1.4.2
Traversing arm data
A definition of the designations/names used is provided in the following text.
Winding width
Winding width is the traversing distance that the traversing arm moves through
between two reversal points. From experience, the width of the wound roll can be
somewhat narrower as the materials being would can more towards the wound roll
at the reversal points depending on the particular product, tension and other
effects. In this application, the winding width is parameterized using the righthand
and lefthand reversing point.
Version 1.01
10.01.2014
11/57
Application description
Basic information
SINAMICS Traversing
Winding step
Winding step is the traversing distance that the traversing arm moves through
during one winder revolution. This means that this parameter defines the “gradient”
of the material.
Acceleration distance
Acceleration distance is the distance that the traversing arm moves through from
the reversal point up until it reaches its final traversing velocity.
Waiting angle
Copyright Siemens AG 2009 All rights reserved
Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
This is the angle at the winder drive that this moves through until the direction of
the traversing arm reverses. This allows the length of material that is wound at the
same traversing arm position to be selected. As a consequence, among others
things, the stiffness/hardness of the wound roll is influenced at the edges of the
roll.

Application functions
2.1
Tasks that can be addressed using the core function
The “traversing arm” application is used to control translatory equipment to wind
materials (wire, textile fibers, etc.).
The “traversing arm” core function handles the preparation of the axis commands
necessary to control the traversing arm axis.
All of the functions of the basic positioner module (EPOS) can be controlled from
the application via HMI and SIMATIC S7.
The function can/must be expanded by making the appropriate additions in the
SIMATIC S7 user program – so that it can run on an actual machine.
2.2
Characteristics of the core function
Copyright Siemens AG 2009 All rights reserved
Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
The application essentially comprises a DCC program that controls the traversing
arm axis via the MDI direct setpoint input mode of the EPOS. All of the data
relevant for the traversing arm is entered into the program and additional data is
then internally calculated from this.

You can start and monitor/visualize the traversing arm under the AUTO screen
form. To start the traversing arm, power-up the traversing axis by pressing “On”
and start the traversing arm using “Traversing START”. The traversing arm is
presently still at a standstill as the winder axis is also still at a standstill. You can
simulate the winder. To do this, under “simulated winder speed”, select a winder
speed of e.g. 200 RPM and click on “activate”. Instead of simulating the winder,
you can also operate this in STARTER/SCOUT from the control panel.

Preparation
Before integrating the core function, you should parameterize the Profibus DP
interface in the hardware configuration, transfer the WinCC flexible project and
parameterize the drives.
Adaptations in the SIMATIC Manager
The DP interface is parameterized in the hardware configuration of the SIMATIC
Manager.
When selecting a CPU with integrated DP interface or a DC communication
processor from the STEP 7 hardware catalog, the hardware configuration is made
available to a PROFIBUS-DP master system. After setting the master parameters
(e.g. baud rate), the SINAMICS must be assigned the Profibus bus line from the
hardware catalog.
After completing the DP configuration, you should copy the following blocks into
your new project: OB1, FC100, DB100, UDT101, UDT102, VAT_100, SFC14 and
Version 1.01

SFC15. The OB1 only calls FC100. Communications for the traversing arm axis
is already set-up in the FC100.
Accepting the WinCC flexible project
Copy the WinCC flexible project into your own SIMATIC project. First open the
project with WinCC flexible and from the project menu select “Copy from STEP7”.
After succesfully exporting the data select in the same menu “Integrate in STEP 7”
and search for your own project. You have to set up additionally the connection
parameters in NetPro.

Configuring the drive
We recommend that an automatic configuration is carried-out in advance so that
the individual drive objects are correctly identified. The most important steps are
again described below:
Go ONLINE and start the automatic configuration.
Then again configure the drive involved OFFLINE. In this case, the basic
positioner function module should be selected.

Rename the axis that you wish to use as traverser (traversing arm) into
“Traverser”. This is necessary so that when compiling the DCC chart, the BICO
interconnections can be interconnected.
Using the righthand mouse key, click on the DCC chart in the project window
and select the “Accept and execute” menu item.
Using the righthand mouse key, click on the DCC chart in the project window
and select the menu item “Set execution groups”. Select BEFORE basic
positioner (EPOS). This means that the DCC chart is always computed in the
clock cycle 4ms before EPOS.

Open the expert list of the drive object. For the case that the winder axis is
computed on the same CU as your traversing arm axis, interconnect parameter
p21510 with parameter r63 of the winder axis. This means that you enter the
actual winder speed into the traversing arm application.
Then interconnect parameter p21511 with parameter r2700 of the winder axis.
This means that you enter the reference speed of the winder into the traversing
arm application.
In parameter p21518, set the gear ratio between the load revolution and
encoder revolution as decimal number.
For the case that you enter the winder speed via Profibus, interconnect
parameter p21512 with parameter r2050[15] of your traversing arm axis. This
means that you enter the actual winder speed into the application. The encoder
value received from Profibus of between 0 and 65535 always corresponds to a
speed of between 0 and 6000 rpm in the application. If parameter p21512 is
interconnected, then it is not permissible that parameter p21510 is
interconnected. The reference speed that you can enter into the application via
parameter p21511 has no effect.

Configuring examples
7.4.1
Shorter sampling time
The sampling time of the application also has an influence on the traversing
accuracy – in addition to material guidance, material behavior, achievable accuracy
of the control loops etc. In the basic setting, EPOS is sampled every 4 ms - and
therefore also the DCC application. As the application controls EPOS, it does not
make any sense to sample the application faster than EPOS.
Due to the requirements relating to accuracy of the waiting angle, an internal
compensation circuit is implemented, which further optimizes the sampling time.
In most cases, none of these effects have an impact on the traversing result.
However, if the effects are visible, then a shorter sampling time can be used. The
sampling time can be shortened as follows:
Copyright Siemens AG 2009 All rights reserved
Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
If the winder is computed on the same CU 320, the sampling time of the winder
and EPOS can be reduced to 2ms. If the winder is computed on another drive,
then the sampling time and EPOS can be reduced to 1ms. However, if the
winder is computed on another drive, then this means that the winder actual
speed value comes from Profibus. With this configuration, then a cycle time of
1 ms should also be set for Profibus.
Go online with Starter/Scout.
Open the expert list of the CU and set parameter p9 to the value 3.
Open the expert list of the traversing arm and set parameter p112 to the value
0 (expert). Then set parameter p115[5] to 2000.0 s if you wish to set a
sampling time of 2ms - or to 1000.0 s if you wish to set a sampling time of
1ms. You have then set EPOS to the required sampling time.
Also set parameter p21515 to the selected sampling time of 2ms, or 1ms. This
means that you also adapt the optimization to calculate the delay time in the
waiting angle.
In the expert list, set parameter p9 back to the value of 0. The CU 320 then reboots. As the DCC chart is in the execution group “BEFORE basic positioner”,
the sampling time of the DCC chart automatically adapts itself to that of EPOS.
7.4.2
Execution sequence
The execution sequence of the DCC chart has already been optimized. Further
optimization using the automatic optimization of the execution sequence function
results in the application malfunctioning.
7.4.3
Measures when the winder speed actual values fluctuate
If, when testing the traversing arm, you identify that the speed actual value and
speed setpoint of the traversing arm manifest unexpectedly high fluctuations, then
the cause is as follows:
When the winder controller has been poorly set (i.e. poorly optimized), then its
speed characteristic fluctuates. As a result of the actual value coupling to the
traversing arm, the speed characteristic already starts to fluctuate in the setpoint
(refer to the diagram below).

Fig. 7-9: Unfavorable setpoint from the winder
Copyright Siemens AG 2009 All rights reserved
Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
In order to minimize the setpoint fluctuations, proceed as follows:
Optimize the winder control parameters.
If this does not lead to the desired success, then in exceptional cases, the
traversing arm can be coupled to the setpoint of the winder instead of the actual
value as follows:
Open the expert list of the traversing arm and connect parameter p21510 with
parameter r60 (speed setpoint) of the winder. In so doing, the connection to
parameter r63 (speed actual value) is disconnected.

Structure
The application essentially comprises controlling the MDI – setpoint input function
of EPOS. The objective of the application is to enter – alternating - the end position
as target positions of the application. The acceleration distance is implemented
using the acceleration and deceleration override. The winding step is realized
using the velocity override.
Further, there is a changeover switch in the application that changes over (toggles)
between normal MDI operation and traversing operation.

The traversing mode is switched-in and switched-out and a changeover made
between the righthand and lefthand end position on this page. The end positions
are target positions for the MDI. The system positions in absolute terms with MDI
with continuous setpoint transfer.
A numerical changeover switch toggles (switches between) the two setpoints. The
changeover switch is controlled from an XOR logic element. There are two
possibilities of changing the direction. Either the flip-flop is controlled that changes
over the "waiting angle reached" feedback signal at each signal edge. Or, the
winding direction of rotation changes and the traversing direction must also be
changed.
The flip-flop is also used to select a specific target position if either “Start Pos A” bit
or “Start Pos B” bit is set. In addition, when one of these bits is set, then traversing
operation is activated and by selecting the MDI mode, a changeover is made to
traversing operation (complete changeover, chart page 6).

Page 2:
The waiting angle and the traversing counter are implemented here.
The waiting angle is realized by integrating the winder velocity over time.
Integration is started if the “target position reached” signal is received from the
EPOS standstill monitoring (zero speed monitoring). The integrator is limited to the
required waiting angle. This means that the “integrator at upper limit” signal can be
used as “waiting angle reached” signal. It takes one EPOS clock cycle (e.g. 4 ms)
between the signal – where EPOS receives the new position – up to when it
outputs a speed setpoint (i.e. until the new position is reached). A delay angle is
obtained by multiplying this delay time by the actual winder speed. This delay angle
is subtracted from the specified delay angle. This means that the traversing arm is
controlled earlier by the angle that the winder moves through until the traversing
arm starts.
Copyright Siemens AG 2009 All rights reserved
Manual_SINAMICS_DCC_Traversing Drive_V1.01.doc
The integrator is calculated as follows. The integrating time constant of the
integrator block is 10ms. This is the reason that the speed at input X of the
integrator block must be entered in degrees/10ms. The speed specified by the user
in rpm is initially referred to 6000 rpm. This is converted into the units of
degrees/10ms - required by the integrator block - as follows:
rev
min
360 deg rees
60 s
360 deg rees
60000ms
360
6000
Degrees
10ms
The speed of the winder was converted to a value between 0 and 1 referred to
6000 rpm (refer to the explanation on Page 3). This means that the speed was
already divided by 6000 and only has to be multiplied by 360.
The traversing counter increments by 1 each time the “target position reached”
signal is received during traversing operation.
Page 3:
The winder speed is determined. The speed that the winder reads is a value
between 0% and 100% of the reference speed of the winder. This is the reason
that the winder reference speed is also read-in and the winder speed is converted
to between 0% and 100% - referred to 6000 rpm - for internal processing.
As an alternative, the winder speed can also be read-in from an external encoder.
The external encoder is always referred to a speed of between 0 and 6000 rpm. In
this case, the selected reference speed is not taken into account.
The gear ratio between a load revolution and motor revolution can be applied to
the winder speed.

Velocity, acceleration and deceleration overrides are quantities referred to the
setpoints in parameters p2691, p2572 and p2573. This is the reason that the
setpoints in parameters p2691, p2572 and p2573 are read-out and the override
correspondingly scaled. As these parameters are setting parameters, they are
read-out by a system function. The read-out operation is initiated by a flash
function every 2s.
Page 5:
Changeover of the MDI between traversing operation and MDI is realized here.
When switching-in traversing operation, a flip-flop is set on chart page 1 that
changes over several numeric changeover switches on this chart page. These
changeover switches either change over the MDI signals of the application to the
MDI or the MDI signals that are received from SIMATIC S7 via Profibus.
Acceleration as well as deceleration override are limited to a minimum of 5% in
traversing operation.

Profibus communication in SIMATIC S7
All of the relevant data to traverse and to control EPOS are cyclically transferred to
the SIMATIC S7 via the Profibus interface. Communication via the free telegram
configuration is interconnected in the SINAMICS drive. Communication is
configured as follows on the SIMATIC S7:
OB1 calls FC100. Communication for the traversing arm axis is set-up in the
FC100. The SFC14 and SFC15 system functions are called in the FC100; these
are used to transfer data from and to the drive. The data are in DB100. There is a
send and a receive area. The structures for sending (UDT101) and receiving
(UDT102) are saved in the user-defined data types (UDT).

Test and fine setting
The test can be made using the actual winder – and also using the simulation
function of the winder in the WinCC flexible “Auto” screen form. The trace function
is used to evaluate the functionality of the traversing arm. If the position controller
is to be activated at the winder drive, then, for example, the waiting angle can be
directly checked by comparing the position actual value of the winder and the
speed setpoint of the basic positioner.
Further, before tests are started, the position controller and speed controller of the
axes should be optimized.
Limits of the reference parameters

The application calculates the acceleration and velocity of the traversing arm as
override. The acceleration and deceleration override can be a maximum of 100%
and the velocity override a maximum of 200% of the reference parameter. The
application cyclically reads-out the reference parameters. The application
subsequently scales the override so that the acceleration/deceleration results in the
acceleration distance or the velocity of the parameterized winding step
parameterized by the user.
In order to check whether the override is not limited, under Technology ->
Basic positioner, open the MDI setpoint input screen form. There, select
“Analog signals”.
Check whether the acceleration and deceleration overrides are less than
100%. Check whether the velocity override is less than 200%.

If you must change a parameter as described in the following, first power-down
the traversing axis. The reason for this is that the application must first accept

the new values and must adapt the override. Otherwise, it can occur that the
traversing arm will accelerate at an unexpectedly high level or will move at a
high velocity. You should also carefully note that with the change
parameterization, it is possible that the mechanical load capability of your
traversing arm will be exceeded.
For the case that the velocity override is too high, in the MDI configuration
screen form, open the fixed setpoints and set a higher value in reference
parameter p2691 (reference quantity for the velocity override). For a reference
parameter with a higher setting, the application calculates a lower velocity
override in order to achieve the required angle step.
For the case that the acceleration and deceleration override are too high,
under Technology, open the limits screen form. Set higher values for reference
parameter p2572 and parameter p2573. With the higher setting for the
reference parameter, the application calculates a lower acceleration and
deceleration override in order to achieve the required acceleration distance.

Read the angle that the traversing arm moves through. In our particular case,
this is 39590 LU. In this example, 36000LU is parameterized for each winder
revolution. This means that this value corresponds to angle of 39.6 degrees. A
waiting angle or 40 degrees is parameterized in the example.
In order to check the acceleration distance, now position the measuring cursor
at the start and end of the acceleration phase.

Read-off the acceleration distance. In this example it is 10300LU. In this

of 10 mm is parameterized in the example.
