System overview

2.5 DC link components

2.5 DC link components
Braking Modules enable braking resistors to absorb the regenerative energy produced
during drive deceleration, which is then converted into heat.
Using a Braking Module and braking resistance it is also possible to brake motors when the
power fails.
2.5.1

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

For smaller drive 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.
