Glossary

Active Line Module
Controlled, self-commutating feed/feedback unit (with -"IGBT"s in feed/feedback direction),
which supplies the DC link voltage for the -> "Motor module".
Antriebsobjekt
A drive object is an autonomous, individual software function with its own -> "Parameters"
and may also have its own -> "Fault"s and -> "Alarm"s. Drive objects may exist by default
(e.g. On Board I/O) can be created individually (e.g. –> "Terminal Board" 30, TB30) or also
as multiples (e.g. –> "Servo Control"). As a rule, each drive object has its own window for
parameterization and diagnostic purposes.
Basic infeed
Overall functionality of an infeed with –> "Basic Line Module" including the required
additional components (filters, switching devices, etc.).
Basic line module
Unregulated line infeed unit (diode bridge or thyristor bridge, without feedback) for rectifying
the line voltage of the -> "intermediate circuit".
Compact Flash Card
Memory card for non-volatile storage of the drive software and corresponding –>
"Parameters". The memory card can be plugged into the –> "Control Unit" from outside.
Control Unit
Central control module in which the control and monitoring functions for one or several ->
SINAMICS -> Line modules, and/or -> Motor modules are implemented.
There are three types of control units:
● SINAMICS Control Units, e.g. -> "CU320"
● SIMOTION Control Units, e.g. -> "D425" and -> "D435"
● SINUMERIK solution line control units, e.g. NCU710, NCU720 and NCU730
