SINAMICS S120 Motor Modules as 3-phase Braking Modules

Design
SINAMICS S120 Motor Modules in Chassis format (air-cooled and liquid-cooled) can be used as 3-phase Braking
Modules. Their application as a Braking Module is recommended whenever very high braking powers, particulary
extremely high continuous braking powers, are required.
Motor Modules can be used as Braking Modules only for less dynamic braking processes because, at about 4 to
5 ms, their response time is 3 times as long as the response time of the Braking Modules designed for mounting in
units in Chassis format, and of the Central Braking Modules included in the SINAMICS S120 Cabinet Modules
product spectrum. These have a response time of only 1 to 2 ms.
SINAMICS S120 Motor Modules operating as 3-phase Braking Modules are connected to the DC busbar, protected
and precharged in the same way as Motor Modules used for their standard purpose. Where possible, they should be
positioned within the drive configuration at the point at which the highest quantity of regenerative energy is fed into
the DC busbar, i.e. if possible next to the Motor Modules which regenerate the most energy.
