Active Line Module
Active Line Modules can supply motoring energy and feed back regenerative energy into the
line supply. If required, Active Line Modules can provide reactive power compensation.
Note
You can find a description of the Active Line Modules in the "SINAMICS S120 Power Units
Chassis Liquid Cooled" Manual, Chapter "Line Modules / Active Line Modules".

Motor Modules
Motor Modules are power units (DC-AC inverter) that provide the power supply for the motor
connected to them. Motor Modules are supplied with power via the DC link of the drive unit.
Note
You can find a description of the Motor Modules in the "SINAMICS S120 Power Units Chassis
Liquid Cooled" Manual, Chapter "Motor Modules".
2.5.5
Central Braking Module
The Central Braking Module is used if the motors are operating in the generator mode, and it
is not possible to feedback power into the line supply. The Central Braking Module then limits
the DC link voltage at a central position in the drive line-up.
Note
You can find a description of the Central Braking Modules in the "SINAMICS S120 Cabinet
Modules" Manual, Chapter, "Cabinet Modules / Central Braking Modules".
2.5.6
Auxiliary Power Supply Modules
The Auxiliary Power Supply Module supplies the following components:
● External loads
● Electronic modules
Note
You can find a description of the Auxiliary Power Supply Modules in the "SINAMICS S120
