This Guide uses a specific example for channel 1 (axis 1) with servo drive or step drive with four
operational steps in successive order. These lead to a functioning application with which you can
execute a traversing movement and familiarize yourself with and test the basic hardware and software
functions of your FM 453. The references to the manual will give you your first impression of the
information to be found there.
The handling of channels 2 and 3 is similar to channel 1. Differences will be appropriately noted.
Depending on your level of experience, you will need approximately 1 1/2 to 2 1/2 hours to work
through this example.
Hardware and software requirements
The following requirements must be fulfilled:
•
You have a SIMATIC 400 station comprising a power supply module and a CPU with a mounting
rack.
•
You have an FM 453 module, the configuration package for the FM 453, and the necessary
accessories such as front connector and wiring material.
•
You have a power section (e.g. SIMODRIVE 611-A or FM STEPDRIVE), a motor (e.g. 1FT5 or
SIMOSTEP) and the appropriate setpoint cable. The power section and the motor are in operation.
•
You have a rotary incremental encoder (only for servo drive) and the appropriate measurement
system cable.
•
STEP 7 (V3.1 for later) is installed correctly on your programming device.
Installing and wiring the FM 453
Hang the FM 453 onto the rail, swing it downwards, and screw it in place. You will find more detailed
instructions in Section 3.1 of the Manual.
Wire up the front connector X1 and fasten it into place. Connect it to an auxiliary 24 V supply for the
encoder supply (only for servo drives). The reference potential (analog ground) for the auxiliary supply
is to be connected with the reference potential for the CPU terminal. You can find more information
about connecting the front connector in Sections 4.6 and 4.7 in the Manual.
Connect the drive to channel 1:
Wire the free cable end of the connecting cable to the terminals of the drive unit or plug the female
sub-D connector (15 pin) into the FM STEPDRIVE module. (The terminal identifiers on the cable ends
indicate the proper terminals for SIMODRIVE units.) For SIMODRIVE devices it is required that motor
rotation be to the right for positive setpoint value speeds. For SIMODRIVE devices, the pulse must be
enabled by connecting 24 V to the input GATE_N. Insert the sub-D connector (50 pin) in the connector
X5 on the FM 453. Lock the connector in place with the knurled screws. For more information on
connecting the drives, see Sections 4.2 and 4.3 of the Manual.
Connecting the encoder (only for servo drives):
Connect the connecting cable to the encoder. Insert the sub-D connector (15 pin) into the X2 socket of
the FM 453. Lock the connector in place with the knurled screws. For more information on connecting
the drives, see Sections 4.4 and 4.5 of the Manual.

Connect the programming device to the CPU.
Switch the CPU to the STOP state.
Test: Switch on the power on the power supply module. After a successful internal module test, none
of the three LEDs (INTF, EXTF, STAT) should be lit.
Installing the configuring package on the programming device
The configuring package contains the parameterization tool “Paramerterize FM 453”, which contains
functions (FCs), the data structure (UDT 1), a pre-programmed example interface for OP 7/17
(irrevelant here) as well as user examples.
Insert the CD ROM in the CD ROM drive of your PG/PC.
Run file Setup.exe on the CD ROM.
Follow the step by step instructions given by the installation program.
The software is installed in the following default directories:
•
Parameterization tool “Paramerterize FM 453”: “Siemens\Step7\S7FUPOS”
•
Function blocks: “Siemens\Step7\S7LIBS\FMSTSV_L”
•
Interface for OPs: “Siemens\Step7\EXAMPLES\FM453\zEn17_02_FM453_OP_EX”
•
User examples: “Siemens\Step7\EXAMPLES\zEn17_02”
STEP7 project name: “zEn17_02_FM453_EX”
•
MD-DBs (startup of stepper motor control): “Siemens\Step7\EXAMPLES\FM453\MD”
The installation of the configuring package is also described in Section 5.1 of the Manual.
Parameterizing the FM 453
If you haven’t yet created a project, then proceed as follows:
Create a new project in the SIMATIC Manager create a new project with the commands File
"
New
"
Projects and give it a name. Insert your project in the newly created project window with the
commands Insert
SIMATIC 400 Station.
Select the SIMATIC 400 Station . Access the S7 hardware configuration with the commands Edit
"
"
Open object .
With Insert
"
Hardware Components or View
"
Catalog open the hardware catalog. Within this
catalog select SIMATIC 400
"
RACK-400
"
CR2/UR1/UR2 (depending on the rack). Then drag the
rack into your hardware project.
Select, in the same way, the power supply module, the CPU and the FM 453 module with the
corresponding reference numbers (MLFBs) in the hardware catalog and drag them into the desired
slot (slot 1 for the power supply, slot 3 for the CPU, slot 5 for the FM 453).
Save and compile the created hardware project with the commands Station
"
Save and Compile .
Note: Now, your project contains the configured CPU and FM 453.
Select the FM 453 in your hardware project.
Open the “Properties – FM 453 – (R0/S5)” dialog with Edit
Object Properties .
Click on the Parameters... button to open the user interface “Parameterize FM 453”.
Confirm the message to save the project with OK .

Servo drive
By clicking on the button MD in the overview window a new machine data data block (DB-MD) for
channel 1 is opened. This DB MD is preset with default values (figure “Machine Data).
With these default values and by configuring your plant as follows you can execute a traverse
movement:
•
Power section: SIMODRIVE 611-A
•
Motor: 1FT5
•
Encoder: rotary incremental encoder 2 500 increments per revolution
If your plant is configured differently, you have to parameterize the following machine data according
to your configuration:
•
Controller data:
MD26 “Zero speed range”
•
Axis data:
MD23 “Maximum speed”
•
Encoder data:
MD11/12 “Distance per encoder revolution”
MD13 “Increments per encoder revolution”
Stepper motor
By installing the configuring package you have installed the directory “FM453\MD”. This directory
contains data blocks for machine data to start up FM STEPDRIVE and the corresonding SIMOSTEP.
These DB-MDs are preset with machine data which allow you to execute a traversal movement.
In the directory “[STEP7 directory]\EXAMPLES\FM453\MD” open the MD file for the desired motor for
channel 1 with the command File
Import (note file extension!).
e. g. si02_453.md for SIMOSTEP 2 Nm motor.
In the tab “Drive interface” under MD37 deactivate the Drive ready active setting. In the tab “Drive
data” deactivate the “Phase current control of drive” setting.
If you have a different plant configuration, you have to parameterize your machine data according to
your configuration:
Drive data: MD11/12 “Distance per motor revolution”
MD53 “No. of steps per motor revolution”
If you have customized your servo drive or stepper motor configuration parameters, proceed
as follows.
Save the DB-MD with File
"
Save .
Close the “Machine data” window.
In the overview window click on the button Transfer data to FM... .
In the dialog box “Transfer of data blocks” under “Data block offline” select the machine data block
“DB 1205”.
By clicking on the button Transfer to FM you transfer the MD-DB to the FM 453.
Close the dialog box.
Test: You have set up the necessary safety proceedures for moving an axis!
Open the startup window with Test
"
"
Startup or by clicking on the button Startup in the
overview window.
Set the operating mode to Jogging .
Click Controller enable and Drive enable .
Enter Override 50 %.
Click the button R+ .
You can now execute a traversal movement by pressing the space bar . The motor will turn
(according to the speed set in step 1) as long as you hold the space bar down. You can monitor
the actual position in the startup interface (properties of axis according to default values).
