Description

The braking module (and an external braking resistor) is required to bring drives to a
controlled standstill in the event of a power failure (e.g. emergency retraction or
EMERGENCY OFF category 1) or limit the DC link voltage if the generator is operated for a
short period of time, because a Basic Line Module cannot feed the energy back into the
network.
The Braking Module includes the necessary power electronics and control. When the
Braking Module is in operation, the regenerative energy is dissipated as thermal energy in
an external braking resistor.
To connect the MASTERDRIVES braking module to a SINAMICS S120 Booksize group, you
require either the DC link rectifier adapter, order number 6SL3162-2BM00-0AA0, or the DC link
adapter, order number 6SL3162-2BM01-0AA0. The connection leads used to connect the
braking module to the DC link rectifier adapter or DC link adapter should be as short as
possible.
Please observe the instructions in Chapter "DC link rectifier adapter" and "DC link adapter".
For information on the MASTERDRIVES braking module, please refer to the "MASTERDRIVES
Braking Module" Operating Instructions, order number 6SL3097-2AC00-0AP5.
Only MASTERDRIVES braking modules order numbers 6SE7031-6EB87-2DA1 and
6SE7032-7EB87-2DA1 are approved for operation of Basic Line Module 100 kW.
