Braking Modules as an option for a Motor Module or a Line Module

For lower braking powers, Braking Modules are available with continuous braking powers up
to 50 kW. These Braking Modules are available as option L61/L64 (25 kW) or L62/L65 (50
kW) for Basic Line Modules, Smart Line Modules, Active Line Modules or Motor Modules.
2.5.2

Central Braking Modules

For larger braking powers, separate Central Braking Modules are available. These modules
are implemented centrally in the drive line-up. To increase the braking power, up to four
Central Braking Modules can be connected in parallel.

Motor Modules

There are two different types of Motor Module available with the SINAMICS S120 Cabinet
Modules drive system.
2.6.1

Booksize Base Cabinets with Booksize Cabinet Kits

Motor Modules at the low end of the power range (1.6 to 107 kW) can be configured as
Booksize Cabinet Kits installed in Booksize Base Cabinets. Booksize Cabinet Kits are also
available as Double Motor Modules in the 1.6 to 9.7 kW power range.
2.6.2

Chassis Cabinets

Each Chassis Cabinet is fitted with one SINAMICS S120 Motor Module in chassis format
and covers the 75 to 1200 kW power range.
Higher powers can be achieved by connecting the Motor Modules in parallel.
2.7

Auxiliary Power Supply Modules

Auxiliary Power Supply Modules supply power to the auxiliary power supply system of the
SINAMICS S120 Cabinet Modules.
The fans of the SINAMICS S120 devices installed in the Cabinet Modules are some of the
devices connected to this auxiliary power supply system. In addition, the auxiliary power
supply system supplies the electronics modules with external 24 V DC. This is required when
the DC link is not charged in order, for example, to maintain PROFIBUS communication.
