Overview
Line Module
A Line Module is a power component, which creates the DC link
voltage for one or several
→
Motor Modules from a three-phase
line supply voltage.
The following types of Line Module are used in the SINAMICS
system:
→
Basic Line Module and
→
Active Line Module.
Motor Module
A Motor Module is a power unit (DC-AC inverter) that provides
the power supply for the connected motor.
Power is supplied through the
→
DC link of the drive line-up.
A Motor Module must be connected to a
→
Control Unit
via
→
DRIVE-CLiQ. The open-loop and closed-loop control
functions of the Motor Module are stored in the Control Unit.
PROFIBUS
Standardized fieldbus according to IEC 61158, Parts 2 to 6.
PROFIdrive
PROFIBUS profile specified for speed and position-controlled
drives by the PROFIBUS user organization (German: PNO).
The latest version is the PROFIdrive V3 profile.
Sensor Module
Hardware module for evaluating speed/position encoder
signals.
Synchronous motor
Synchronous motors run at the same frequency with which
they are operated: They have no slip (which is the case with
→
induction motors). Synchronous motors require different feed-
forward and feedback control concepts depending on their
design to ensure that they can be operated with converters.
Synchronous motors are distinguished by the following features:
•
permanent-field/separately excited
•
with/without damping cage
•
with/without position encoder.
Synchronous motors are used for different reasons:
•
high drive dynamic response
•
high overload capability
•
high speed accuracy with exactly specified frequency
(SIEMOSYN motors).
Terminal Module
Terminal extension module for snapping onto the installation rail,
for installation in the control cabinet.
In SINAMICS, the TM31 Terminal Module is available with analog
and digital I/O terminals.
DC link
The component of the converter (or converter system) that
connects the input converter (rectifier) and the output converter
(one or more inverters).
With voltage source DC link converters like SINAMICS, a
constant DC voltage is present in the DC link (rectified line
voltage).
