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:
S You have a SIMATIC 300 station, comprising a power supply module and a CPU 31x (including a
DIN rail as subrack).
S 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.
S 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.
S You have a rotary incremental encoder (servo drive − FM 354 only) and matching measuring sys-
tem cable.
S STEP 7 (V5.3 + SP2 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.
