2.3 Line Modules
The Line Modules perform the function of the central energy infeed for the DC link.
The following Line Modules are available:
● The Active Line Module (ALM) is a self-controlled infeed/regenerative feedback unit for
creating a regulated DC link voltage. This decouples the connected Motor Modules from
the supply voltage and fluctuations within the permitted supply tolerances do not have
any effect on the motor voltage.
The Active Line Module communicates via DRIVE-CLiQ with the CU320 control unit.
● The Basic Line Module (BLM) is an infeed unit that cannot actively regenerate into the
supply. This means that it can only be used for those applications in which the energy
exchange takes place between the motor- and the generator-driven axes in the DC link.
The Basic Line Module communicates via DRIVE-CLiQ with the CU320 control unit.
● The Smart Line Module (SLM) is a non-regulated infeed/regenerative feedback unit with
100% regenerative continuous capability. The regenerative capability of the module can
be deactivated using a digital input.
Certain SLM types have a DRIVE-CLIQ interface (usually starting with 16 Kw).
The Smart Line Modules with DRIVE-CLIQ interface are treated like Active Line Modules
(see Interconnection of the DRIVE-CLiQ components (Page 17)). The control of the
module
s
without DRIVE-CLIQ interface must be implemented with hard wiring
(see Additional hardware wiring for Smart Line Modules without DRIVE-CLi
Q (Page 21
)).
2.4 Motor Modules
The Motor Modules operate as inverters and are available for various output currents and in
various performance classes. They obtain the energy for the motors from the DC link of the
attached Line Module.
The following Motor Module classes for controlling the motors are available for the
SINAMICS S120:
● Single Motor Modules in single-axis design in booksize format
● Double Motor Modules in two-axis design in booksize format
