7.3.8 Free function blocks
7.3.8.1 Overview
Application, properties
A logic operation, which connects several states (e.g. access control, plant status) to a
control signal (e.g. ON command), is required for controlling the drive system in a wide
variety of applications.
Along with logic operations, a number of mathematical functions and storing elements are
becoming increasingly important in drive systems.
This functionality is only available as a "free function blocks" function module (FBLOCKS) on
the SERVO drive object type of SINAMICS S110.
In the free function blocks, analog signals are treated as dimensionless per unit variables
(see the "Connection to the drive" chapter).
Note
This additional functionality increases the calculation time load. This means that the
maximum possible configuration with a Control Unit may be restricted (see the "Calculation
time load" chapter).
