Overview
Braking Module booksize compact 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 OFF
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 power is converted into heat loss in an external
braking resistor. Braking Modules function autonomously. Several
Braking Modules in booksize compact format can be operated in
parallel. In this case, each Braking Module must have its own
braking resistor. Braking Modules in booksize compact format
can also be used for rapid discharge of the DC link.

Design
The Braking Modules in booksize compact format can be
integrated in drive line-ups in booksize and booksize compact
formats.
The Braking Module in booksize compact 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
•
Connector X1 for connecting the braking resistor
•
Connection for thermostatic switch for monitoring the braking
resistor
•
4 DIP switches for setting the operating threshold, selecting
the braking resistor and the cooling method for the Braking
Module
•
2 digital inputs (disable Braking Module/acknowledge faults
and rapid discharge of DC link)
•
3 digital outputs (Braking Module disabled, prewarning from
I
×
t
monitor and set activation threshold)
•
2 PE (protective earth) connections
The status of the Braking Module is indicated via two 2-color
LEDs.

Technical specifications
1)
The activation threshold of the Braking Module in booksize compact format
can be set on a DIP switch. The higher values for peak or rated braking
power apply in operation at the upper activation threshold 775 V DC
(factory setting). The outputs specified in parentheses are possible at
the lower activation threshold 410 V DC.
2)
Several Braking Modules in the booksize format can be operated in
parallel, typically up to 4 modules.

Accessories
Spacing bolt
(4 units)
The mounting depth of modules in booksize
compact format is increased when it is
mounted on these spacing bolts by such an
amount that it can be integrated into a drive
line-up in booksize format. 2 spacing bolts
are needed to mount 50 mm (1.97 in) wide
modules.
