Small SINAMICS 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".
Drive
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 inverter system.
With a converter system (e.g. -> "MICROMASTER 4"), from the point of view of the user the
line infeed, actuator, and control component form a single device; with an inventor system
(e.g. -> "SINAMICS S"), the supply is ensured by means of -> "Line Module", thereby
realizing a DC line to which the -> "Invertors" (-> "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".
Drive unit
The drive unit includes all the components connected via –> "DRIVE-CLiQ" that are required
for carrying out a drive task: -> "Motor Module" –> "Control Unit" –> "Line Module" and the
required –> "Firmware" and –> "Motor"s, but not additional components, such as filters or
reactors.
Several –> "Drive"s can be implemented in a drive unit.
See –> "Drive System".
Drive component
Hardware component connected to a –> "Control Unit" via –> "DRIVE-CLiQ", for example.
Drive unit are for instance: -> "Motor Module"s, -> "Line Module"s, -> "Motor"s, -> "Sensor
Module"s and -> "Terminal Module"s.
