This Guide uses a concrete example to guide you through 4 start-up steps in the order given below

until you have obtained a functional application. You will then be able to traverse an axis and get to

know and try out the basic hardware and software functions of your FM 354 or FM 353. The refer-

ences to the Manual are intended to give you an initial overview of the information contained in the

Manual.

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 preconditions must be fulfilled:

You have a SIMATIC 300 station, comprising a power supply module and a CPU 31x (including a

DIN rail as subrack).

You have an FM 354 or FM 353 module, the associated configuring package and the necessary

accessories such as bus connector, 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 motor have already been

commissioned.

You have a rotary incremental encoder (servo drive – FM 354 only) and matching measuring sys-

tem cable.

STEP 7 (V3.1 or later) is installed correctly on your programming device.

Installing and wiring the FM 354 or FM 353

Insert the bus connector supplied with the FM 354 or FM 353 into the CPU bus connector. Insert the

FM 354 or FM 353 module in the DIN rail, lower it down into position and tighten the mounting screws.

For more detailed instructions, please refer to Section 3.1 of the Manual.

Wire up the front connector. Insert front connector X1 in the FM 354 or FM 353 and lock. For a de-

scription and connection instructions for front connector, please refer to Sections 4.6 and 4.7 of the

FM 354 Manual or Sections 4.4 and 4.5 of the FM 353 Manual.

Connecting up the drive:

Connect the free end of the connecting cable to the terminals of the drive unit. (The terminal designa-

tions at the ends of pre-assembled cables ordered from the catalog are labelled with the appropriate

terminals for SIMODRIVE equipment or the corresponding pin assignments for the subminiature D

socket connector (15-way) for FM STEPDRIVE). The following condition must be fulfilled on SIMO-

DRIVE equipment: CW motor rotation with positive speed setpoint. In the case of STEPDRIVE mo-

tors, a 24 V supply must be applied to input GATE_N for pulse enabling. Insert the subminiature D

socket connector (9-way or 15-way) in connector X2 on the FM 354 or FM 353. Tighten the knurled-

head screws to lock the connector in place. For a description and connection instructions for the drive,

please refer to Sections 4.2 and 4.3 of the FM 354 or FM 353 Manual.

Connecting up the encoder (servo drive – FM 354 only):

Attach the connecting cable to the encoder. Insert the subminiature D connector (15-way) in socket

X3 on the FM 354. Tighten the knurled-head screws to lock the connector in place. For a description

and connection instructions for the encoder, please refer to 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. The red LED marked “SF” on the FM then

lights up briefly and goes out again on successful completion of an internal module test. The

yellow LED marked “DIAG” on the FM lights up briefly after about 8 s and goes out at the same

time as LED “SF”.

When the connections have been made correctly, green LEDs “DC 5V” on the CPU and the FM

354 or FM 353 light up.

Installing the configuring package on the programming device

The configuring package contains the “Parameterize FM 354” or “Parameterize FM 353” tool, the

function blocks (FCs), the data structure (UDT 1), a preconfigured example interface for the OP 7/17

(irrelevant here) and user examples.

Insert the CD ROM in the CD ROM drive of your PG/PC.

Run file Setup.exe on the CD ROM.

Follow step by step the instructions displayed by the installation routine.

The software is installed in the following directories when the defaults are accepted:

“Parameterize FM 354” or “Parameterize FM 353” parameterization tool: “Siemens\Step7\S7FLAG

or \S7FSTEP”

Function blocks: “Siemens\Step7\S7LIBS/FMSTSV_L”

OP interface:

FM 354

When you click on button MD in the main window, a new Machine Data Data Block (DB-MD) is

opened. The parameters of this DB-MD are set to defaults (“Machine Data” display).

These defaults will enable you to traverse an axis if your system configuration is as follows:

Power section: SIMODRIVE 611-A

Motor: 1FT5

Encoder: Rotary incremental encoder with 2,500 increments/rev

If your system is configured differently, then you will need to parameterize the following machine data

to match your configuration:

Controller data:

MD26 “Zero speed range”

Axis data:

MD23 “Maximum velocity”

Encoder data:

MD11/12 “Distance per encoder revolution”

MD13 “Increments per encoder revolution”

FM 353

By loading the configuring package, you have installed directory “FM353\MD”. This directory contains

data blocks for machine data for starting up FM STEPDRIVE and the corresponding SIMOSTEP.

These DB-MDs are assigned machine data defaults which will enable you to traverse an axis.

Select menu commands File

Import to open the MD file (note file type!) for the appropriate motor

in directory “[STEP7 directory]\EXAMPLES\FM353\MD”.

e.g. si02_353.md for a SIMOSTEP 2 Nm motor.

Deactivate the setting Controller Already Active on the index card “Drive Interface” under MD37. Se-

lect setting No Boost, No PWM Active under “Phase Current Control of Drive” on index card “Drive

Data”.

If your system is configured differently, then you will need to parameterize the following machine data

to match your configuration:

Drive interface: MD11/12 “Distance per motor revolution”

MD13 “Steps per motor revolution”

Once you have parameterized the FM 354 or FM 353 to match your configuration, proceed as

follows:

Save the DB-MD by selecting File

→

Save .

Close the “Machine Data” screen.

Click on button Transfer Data to FM... in the main display.
