Standard Technology Functions
The Standard Technology Functions are not restricted to a
specific SINAMICS product family, but they are available in full
or at least partially in SINAMICS S120 as well as in
SINAMICS G120.

Standard Technology Functions
The Standard Technology Functions significantly expand the
application spectrum of the SINAMICS drives because the func-
tions are not permanently and unalterably interconnected;
rather, they are interrupted at defined access points and can be
connected or wired differently. The BICO technology makes it
possible.
The FFBs enable additional, freely interpretable adaptations of
the binary and analog signal flow to the given machine applica-
tion. However, the FFBs are limited in terms of the absolute quan-
tity and the computing intervals (sampling times) that can be
selected. These blocks are NOT multi-instance capable.
With Epos, comprehensive positioning tasks are autonomous in
SINAMICS (i.e. their solution does not need a higher-level con-
trol). And moreover, this integrated functionality is also extremely
flexible: It can be used for highly dynamic servo control as well
as for simple applications with vector-controlled asynchronous
motors. Up to 64 target positions, as well as the respective
traversing speeds, can be permanently stored in the drive
during commissioning. Axes can be positioned either absolutely
or relatively.
It is, however, also possible to transfer these parameters as
required from a higher-level controller. This means that target
positions and velocities can even be changed on-the-fly during
a positioning run.
The technology controller (PID controller) permits all types of
simple process controls to be implemented. It can be used, for
example, to control the line pressure, fill level, temperature, flow
or also tension control or load balancing.
