Configuration instructions
DC link capacitance
To operate Braking Modules, a minimum capacitance of 440 µF is required in the DC link for
each Braking Module.
The capacitance of the Braking Module of 110 µF is included in the total capacitance value.
Note
Only the components that are connected to each other via the DC link busbar can be
included in the total capacitance.
In a multi-row or distributed drive line-up, the DC links are connected to each other via a DC
link cable. When using a Braking Module in the drive line-up, this cable must not be longer
than 10 m. The DC link cable must be twisted and have a minimum cross-section of at least
10 mm

.
The Braking Module Booksize Compact 6SL3400-1AE31-0AA. Is recommended for
connecting Braking Modules in series.
Parallel connection of the Braking Module 6SL3100-1AE31-0AA. should be avoided as
power distribution between the modules is not guaranteed.
Note
When Braking Modules are connected in parallel, the
DC link capacitance specified above
must be available for each Braking Module.
