Overview
Braking Module in booksize format
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 STOP
category 1) or limit the DC link voltage for brief periods of gener-
ator operation, e.g. when the regenerative feedback capability of
the Line Module is deactivated. The Braking Module includes the
power electronics and the associated control circuit. During oper-
ation, the DC link energy is converted 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 DC link connections via integrated DC link busbars
•
2 electronics power supply connections via integrated
24 V DC bars
•
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 pre-warning –
I
×
t
monitoring)
•
2 PE (protective earth) connections
The status of the Braking Module is indicated via two 2-color
LEDs.

Connecting Braking Modules in the booksize format in parallel should be
avoided, as it cannot be guaranteed that the power will be evenly divided
between the modules.
