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 associated
control circuit. During operation, the DC link power 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 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/ground connections
The status of the Braking Module is indicated via two 2-color
LEDs.
