This Guide uses a concrete example to guide you through 5 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 357-2. The references 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 2 to 3 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 (CPU 314 or
later).
You have an FM 357-2 module, the associated configuring package, the memory card with the cor-
responding firmware 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 (for servo drive only) and matching measuring system
cable.
STEP 7 (V4.02 or later) is correctly installed on your programming device.
Installing and wiring up the FM 357-2
Insert the bus connector supplied with the FM 357-2 into the CPU bus connector. Place the FM 357-2
module on the mounting rail, lower it down into position and tighten the mounting screws. For more
detailed instructions, please refer to Section 3.1 of the Manual.
Connect up the power supply to the screw-type terminal block on the FM 357-2. For more detailed
wiring instructions, please refer to Section 4.2 of the Manual.
Wire up the front connector. The NC-READY output must be connected into the EMERGENCY STOP
circuit. Insert the front connector in the FM 357-2 and lock. For a description and connection instruc-
tions for front connector, please refer to Sections 4.8 and 4.9 of the Manual.
Connecting up the drive (servo and stepper drives):
Connect the free end of the connecting cable to the terminals of the drive unit or insert the subminia-
ture D socket connector (15-way) in the FM STEPDRIVE module. (The terminal designations at the
ends of pre-assembled cables ordered from the catalog specify the correct terminals for SIMODRIVE
equipment) Insert the subminiature D socket connector (50-way) in connector X2 on the FM 357-2.
Tighten the knurled-head screws to lock the connector in place. For a description and connection
instructions for the drive, please refer to Sections 4.4 and 4.5 of the Manual.
Connecting up the encoder (for servo drives only):
Attach the connecting cable to the encoder. Insert the subminiature D connector (15-way) in socket
X3 (axis 1) on the FM 357-2. Tighten the knurled-head screws to lock the connector in place. For a
description and connection instructions for the encoder, please refer to Sections 4.6 and 4.7 of the
Manual.
