Small SINAMICS Glossary
Controlled, self–commutating feed/feedback unit (with –>”IGBT”s in feed/feed-
back device), which supplies the DC link voltage for the –>”Motor module”s.
Overall functionality of an infeed with –> Basic Line Module, including the re-
quired additional components (filters, switching devices, etc.).
Unregulated line infeed unit (diode bridge or thyristor bridge, without feedback)
for rectifying the line voltage of the –>DC Link.
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.
Central control module in which the closed–loop and open–loop functions for
one or more –> ”SINAMICS” –> ”Line module”s and/or –> ”Motor module”s 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
Bit–coded –> ”Process data” word. –> which ”PROFIdrive” transmits at cyclic
intervals to control the drive states.
Two motors can be connected to and operated with a double motor module.
See –> ”Motor module” –> ”Single motor module” Former name: –> ”Double–
axis module”
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. –> MI-
CROMASTER 4), from the point of view of the user the line infeed, actuator, and
control component form a single device; with an inverter system (e.g. –> SI-
NAMICS S), the supply is ensured by means of –> Line Modules, thereby realiz-
ing a DC line to which the –> Inverters (–> Motor Modules) are connected. The
–>”Control unit” is implemented as a separate device and connected to the
other components by means of –>”DRIVE–CLiQ”.
Abbreviation of ”Drive Component Link with IQ”.
Communication system for connecting the different components of a SINAMICS
drive system (e.g. –> ”Control Unit”, –> ”Line Module”s, –> ”Motor Module”s, –>
”Motor”s, and speed/position encoders.
The DRIVE–CLiQ hardware is based on the Industrial Ethernet standard with
twisted–pair lines. The DRIVE–CLiQ line provides the transmit and receive
signals, as well as the +24 V power supply.
