A.4 Glossary
Line Module Line Module none
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.
In SINAMICS, three types of Line Module are available:
–> "Basic Line Module", –> "Smart Line Module" –> "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, etc.) is
called –> "Basic Infeed", –> "Smart Infeed", and –> "Active Infeed".
Motor Motor none
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. In
SINAMICS, the motors are connected to a –> "Motor Module".
See –> "Synchronous Motor" –> "Induction Motor" –> "Built-In Motor" –> "Motor Encoder" -
> "External Encoder" –> "Third-Party Motor".
Motor Module Motor Module none
A Motor Module is a power component (DC-AC inverter) that supplies the power 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 –> "DRIVE-CLiQ". The open-
loop and closed-loop control functions for the Motor Module are stored in the Control Unit.
–> "Single Motor Module"s and –> "Double Motor Module"s are available.
Motorgeber Motor Encoder none
An –> "Encoder" (e.g. –> "Resolver", –> "Incremental Encoder TTL/HTL", or –> "Incremental
Encoder sin/cos 1 Vpp" that is integrated in or attached to the motor.
The encoder detects the motor speed. In the case of synchronous motors, it can also detect
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 Encoder"s for –> "Direct Position Sensing"
are available.
Option Board Option Board
PC board inserted in the –> "Control Unit" (e.g. a –> "Terminal Board" 30, TB30).
Option Slot Option Slot none
Slot for an optional module (e.g. in the –> "Control Unit").
Parameter Parameter keine
Variable quantity within the drive system that the user can read and, in some cases, write.
For –> "SINAMICS", all specifications defined in the –> "PROFIdrive" profile are defined by a
