FM 453

Getting Started

First Steps in Commissioning

04/2007 Edition

-2

This Guide uses a specific example for channel 1 (axis 1) with servo drive or step drive with four ope-

rational 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 func-

tions of your FM 453. The references to the manual will give you your first impression of the informa-

tion 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:

SYou have a SIMATIC 400 station comprising a power supply module and a CPU with a mounting

rack.

SYou have an FM 453 module, the configuration package for the FM 453, and the necessary acces-

sories such as front connector and wiring material.

SYou 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.

SYou have a rotary incremental encoder (only for servo drive) and the appropriate measurement

system cable.

SSTEP 7 (V5.3 + SP2 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 con-

necting 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.

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 (irreve-

lant 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:

SParameterization tool “Paramerterize FM 453”: “Siemens\Step7\S7FUPOS”

SFunction blocks: “Siemens\Step7\S7LIBS\FMSTSV_L”

SInterface for OPs: “Siemens\Step7\EXAMPLES\FM453\zEn17_02_FM453_OP_EX”

SUser examples: “Siemens\Step7\EXAMPLES\zEn17_02”

STEP7 project name: “zEn17_02_FM453_EX”

SMD-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 com-

mands 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 corres-

ponding 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.

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 move-

ment:

SPower section: SIMODRIVE 611-A

SMotor: 1FT5

SEncoder: 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:

SController data: MD26 “Zero speed range”

SAxis data: MD23 “Maximum speed”

SEncoder 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 con-

tains 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 over-

view 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).

In the zEn17_02_FM453_EX project you will find other examples which you can use as a guide and

which you can adapt to your application.

Note

In normal operation you should turn on the alarm generation (valid for channels 1 to 3), alarm selec-

tion (valid for channels 1 to 3) and all monitors (per channel).

Alarm generation can be set in the dialog box “Properties −FM 453 −(R0/S5)” in the tab “Basic Para-

meters” (see section 5.2 in the Manual under “Parameterize FM 453”)

You can set monitoring (per channel), e.g. hardware monitoring MD20, software limit switch MD21/22

etc. with parameterize.

Please note that the data will again be transferred to FM 453 and to the CPU.

Diagnostics

Errors can occur as a result of incorrect operation, incorrect wiring, or contradictory parameter assign-

ments which the FM 453 displays with the LEDs “INTF”, “EXTF” and “STAT”
