Glossary
externer Geber
Position encoder that is not built in or mounted on the –> Motor, but via a mechani-
cal transmission element or mechanical intermediate element.
The external encoder (see –> Externally-Mounted Encoder) is used for –> Direct
Position Detection.
Einspeisung
Input component of a converter system for generating a DC link voltage to supply
one or more –> "Motor module"s, including all the required components (e.g.
–> "Line module"s, fuses, reactors, line filters, and firmware, as well as propor-
tional computing power (if required) in a –> "Control unit".
Line Module
A line module is a power component that generates the DC link voltage for one or
more –> "Motor module"s from a 3-phase mains voltage.
The following three line module types are used for SINAMICS:
–> Basic Line Module, –> Smart Line Module, and –> Active Line Module.
The overall function of an infeed, including the required additional components
(–> "Line reactor", proportional computing power in a –> "Control unit", switching
devices, and so on), is called –> "Basic infeed", –> "Smart infeed", and –> "Active
infeed".
Motor
For the electric motors that can be driven by –> SINAMICS, a basic distinction is
made between rotary and linear motors with regard to their direction of motion, and
between synchronous and induction motors with regard to their electromagnetic
operating principle. For SINAMICS, the motors are connected to a –> Motor Mod-
ule.
See –> Synchronous Motor, –> Induction Motor, –> Built-In Motor, –> Motor En-
coder, –> External Encoder, and –> Third-Party Motor.
Motorgeber
An –> "Encoder" (e. g. –> "Resolver", –> "Incremental encoder TTL/HTL", or
–> "Incremental encoder sin/cos 1 Vpp"), which is integrated in or attached to the
motor.
The encoder detects the motor speed and, in the case of synchronous motors,
also the rotor position angle (of the commutation angle for the motor currents).
For drives without an additional –> "Direct position measuring system", it is also
used as a –> "Position encoder" for position control.
In addition to the motor encoders, –> External Encoders for –> Direct Position
Sensing are available.
