Overview
1
Braking Module
A Braking Module and the matching external braking resistor
are 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 for
brief periods of generator operation, e.g., when the regenerative
feedback capability of the Line Module is deactivated. The
Braking Module includes the power electronics and the associ-
ated control circuit. During operation, the DC link power is con-
verted into heat loss in an external braking resistor. Braking
Modules function autonomously.
Braking modules in booksize format can also be used for rapid
discharge of the DC link.

Design
The Braking Module in booksize format features the following
connections and interfaces as standard:
•
2通过集成直流链路连接DC link busbars
•
2 electronics power supply connections via integrated
24 V DC busbars
•
Terminals for connecting the braking resistor
•
2 digital inputs (disable Braking Module/acknowledge faults
and rapid discharge of DC link)
•
2 digital outputs (Braking Module disabled and
prewarning
I
×
t
monitoring)
•
2 PE connections
The status of the Braking Module is indicated via two 2-color
LEDs.
