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".
Geber
An encoder is a measuring system that captures actual values for the speed
and/or angular/position values and makes them available for electronic processing.
Depending on the mechanical construction, encoders can be integrated in the
–> "Motor" (–> "Motor encoder") or mounted on the external mechanics (–> "Exter-
nal encoder"). Depending on the type of movement, a distinction is made between
rotary encoders (also known as "rotary transducers") and translatory encoders
(e. g. –> "Linear encoders"). In terms of measured value provision, a distinction is
made between –> "Absolute encoder"s (code sensors) and –> "Incremental
encoder"s.
See –> "Incremental encoder TTL/HTL" –> "Incremental encoder sin/cos 1 Vpp"
–> "Resolver"
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 oper-
ating principle. For SINAMICS, the motors are connected to a –> "Motor Module".
See –> "Synchronous Motor", –> "Induction Motor", –> "Built–In Motor", –> "Motor
Encoder", –> "External Encoder", and –> "Third–Party Motor".
Motor Module
A motor module is a power unit (DC–AC inverter) that provides the power supply
for the connected motor(s).
Power is supplied through the –> "DC link" of the –> "Drive unit".
A motor module must be connected to a > "Control unit" via a –> "DRIVE–CLiQ".
The open–loop and closed–loop control functions of the motor module are stored in
the control unit.
–> "Single Motor Module"s and –> "Double Motor Module"s are available.
