Overview
Active Line Module
Active Line Modules are self-commutated feed/feedback units
(with IGBTs in infeed and regenerative feedback directions) and
generate a regulated DC link voltage. This means that the
connected Motor Modules are decoupled from the line voltage.
Line voltage fluctuations within the permissible supply
tolerances have no effect on the motor voltage. Active Line
Modules are designed for connection to grounded, star (TN, TT)
and non-grounded, symmetrical IT systems.
The DC link is pre-charged via integrated pre-charging resistors.
In order to operate an Active Line Module, it is absolutely
essential to use the appropriate Active Interface Module.
■
Design
The Active Line Modules in booksize format feature the following
connections and interfaces as standard:
•
1 power connection via screw-type terminals
•
1 connection for the 24 V DC electronics power supply via the
24 V terminal adapter included in the scope of supply
•
1 DC link connection via integrated DC link busbars
•
3 DRIVE-CLiQ sockets
•
2 PE/ground connections
The status of the Active Line Modules is indicated via two multi-
color LEDs.
For the Active Line Module with a width of 100 mm, the shield of
the power connection cable can be connected to the integrated
shield connection plate by means of a shield connection
terminal or hose clip, e.g. Weidmüller type KLBÜ CO 4. The
shield connection terminal must not be used as a strain relief
mechanism. Shield connection sets are available for the
150 mm, 200 mm and 300 mm wide Active Line Modules.
The signal cable shield can be connected to the Motor Module
by means of a shield connection terminal, e.g. Weidmüller type
KLBÜ 3-8 SC.

Design
(continued)
The scope of supply of the Active Line Modules includes:
•
DRIVE-CLiQ cable for connection to the adjacent Control Unit
on the left for drive control, length 0.11 m
•
DRIVE-CLiQ cable (length depends on Active Line Module
width) for connection to the adjacent Motor Module,
length = width of Active Line Module + 0.11 m
•
2 blanking plugs for sealing unused DRIVE-CLiQ sockets
•
Jumper for connecting the 24 V DC busbar to the adjacent
Motor Module
•
24 V terminal adapter (X24)
•
Connector X21 for digital inputs
•
Fan insert for Active Line Modules of 80 kW and 120 kW
(the voltage for the fan unit is supplied by the Active Line
Module)
•
1 set of warning labels in 30 languages
■
Integration
The Active Line Module receives its control information via
DRIVE-CLiQ from:
•
SINUMERIK 828D BASIC
•
