Glossary
Steuerwort
Bit-coded –> "Process data" word. –> "PROFIdrive" transmits this word at cyclic
intervals to control the drive states.
CU320
SINAMICS –> "Control unit" with 4 –> "DRIVE-CLiQ socket"s and 16 digital inputs/
outputs.
Double Motor Module
Two motors can be connected to and operated with a double-motor module.
See –> "Motor module" –> "Single motor module"
Former term: –> Double-axis module
Antrieb
The drive includes the motor (electric or hydraulic), the actuator (converter, valve),
the control unit, measuring system, and supply components (line infeed module,
pressure reservoir).
For electric drives, a distinction is made between a converter system and an in-
verter system. With a converter (e. g. –> "MICROMASTER 4"), the line infeed, the
actuator, and the control component form a single device from the point of view of
the user. With an inverter system (e. g. –> "SINAMICS S"), the supply is ensured
by means of a –> "Line module", thereby realizing a DC link to which the –> "In-
verters" (–> "Motor module"s) are connected. The –> "Control unit" is implemented
as a separate device and connected to the other components by means of
–> "DRIVE-CLiQ".
Antriebskomponente
Hardware component connected to a –> Control Unit via –> DRIVE-CLiQ, for ex-
ample.
Examples of drive components: –> "Motor module"s, –> "Line module"s, –> "Mo-
tor"s, –> "Sensor module"s, and –> "Terminal module"s.
The overall arrangement of a control unit including the connected drive compo-
nents is called a –> "Drive unit".
Antriebsverband
A drive line-up comprises a –> Control Unit and the and the –> Motor Modules and
–> Line Modules connected via –> DRIVE-CLiQ.
Antriebsobjekt
A drive object is an autonomous, individual software function with its own –> "Pa-
rameter"s. It may also have its own –> "Fault"s and –> "Alarm"s. The drive objects
may exist by default (e. g. On-board I/O) and may be easy to create (e. g. –> "Ter-
minal board" 30, TB30). It may also be possible to create more than one (e. g.
–> "Servo control"). As a rule, each drive object has its own –> STARTER window
for parameterization and diagnostic purposes.
