A.1 Glossary
Line Module
A Line Module is a power unit that generates the DC link voltage for one or more –> "Motor
Module"s from a 3-phase line voltage.
In SINAMICS, the following 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 such as a –
> "Line Reactor", proportional computing power in a –> "Control Unit", switching devices, etc.
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. 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
A Motor Module is a power unit (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.
Motor encoder
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 encoders" for –> "Direct position sensing" are
available.
Option slot
Slot for an optional module (e.g. in the –> "Control Unit").
Parameter
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
parameter.
See –> "Visualization parameter"s and –> "Adjustable parameter"s.
