Firmware functionality
Standard Technology Functions
The Standard Technology Functions significantly expand the
application spectrum of the SINAMICS drives because the
functions 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 adaptation of
the binary and analog signal flow to the machine application.
However, the FFBs are limited in terms of the absolute quantity
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 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 commis-
sioning. Positioning can be either absolute or relative.
It is, however, also possible to transfer these parameters as
required from a higher-level controller. This means that target
position and velocities can even be changed on-the-fly during a
positioning run.
The technology controller (PID controller) enables simple
process controls of all kinds. It can be used to control the line
pressure, fill level, temperature, flow or also tension control or
load balancing.

Basic Drive Functions
The main groups, especially the "Basic Drive Functions", are
divided up into further subgroups.
• Control
• Availability
•
Setpoints and commands
•
Limiters, timers and monitoring functions
• Diagnosis
• Protection
Basic Drive Functions - Control Function
Control
The control methods are the core of the entire inverter firmware.
They are responsible for optimum movement of the connected
motor and the attached machines. The better the control
functions, the faster, better and more smoothly the machine
operates, thereby significantly enhancing the quality of the
production output.
A distinction is made between the following methods:
•
V/f control (open-loop control)
•
Vector control (closed-loop control)
•
Servo control (closed-loop control)
