1–STEP–DRIVE–5A–48V
Stepper motor module for the SIMATIC ET 200®S
In Focus

In coordination with SIEMENS
®

The 1-STEP-DRIVE-5A-48V is a stepper motor
controller with integrated power stage. It is
specially developed for application in the
decentralised SIMATIC ET 200®S peripheral
system.

SIMATIC ET 200 S with a fully integrated,
egrated,
powerful and high-precision positioning conng
troller for 2 phase stepper motors.

This 1-STEP-DRIVE module is configured
via mouse click with the STEP®7 by using
the provided configuration files and then
parameterised. The module is ready for use
in a very short time and supplements the

Application examples for the 1-STEP-DRIVE
module are assembly and transfer lines,
building automation, x-y-tables, paper mills,
printing and textile machines.

Application
The 1-STEP-DRIVE-5A-48V module
successfully completed the system
compliance test performed by
SIEMENS.

Highlights

These Phytron power stages are eminently suitable for not only setting the basic
parameters via interface bus, but also the
technological parameters found in the
application.

certain micro step positions cannot often
be reached because of a lack of fine current
settings and the motor may not reach the
desired position. The 1-STEP-DRIVE technology guarantees a high-precision current

The power stage can be optimised for the requirements of the drive system during commissioning. Furthermore it is possible to
adjust the power stage during ´CPU RUN´,
particularly for the next program sequence.
For example, raise the stop current when
the motor is holding a load and then reduce
it as soon as the system comes to a standstill without the load to minimize the power
requirement and motor heating. Using these
functions combined with additional parameters bring out the best in your system.

Fine positioning to 1/512 step
Almost all commercially available stepper
motor power stages can be operated in
micro step mode. When driving the motor
with encoder feedback, it is apparent that

adjustment and enables fine positioning up
to 1/512 step. The diagram above shows
that a Phytron 200 step motor with encoder
is able to be at each 1/512 micro step position with an absolute and non-cumulative
error of about 0.0015°, typically much less
than this.
