Overview
Active Line Module in booksize format
Active Line Modules are self-commutated infeed/regenerative
feedback units (with IGBTs in the infeed and regenerative feed-
back directions) that generate a controlled 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) supply systems.
The DC link is pre-charged via integrated precharging resistors.
In order to operate an Active Line Module, an associated
Active Interface Module is required.

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 (protective earth) connections
•
1 temperature sensor input for KTY84-130, Pt1000 or PTC
(Pt1000 can be used from firmware V4.7 HF17)
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 (3.94 in), the
shield of the power connection cable can be connected to the
integrated shield connection plate by means of a shield connec-
tion 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
(5.91 in), 200 mm (7.87 in) and 300 mm (11.81 in) wide Active
Line Modules.
The signal cable shield can be connected to the Active Line
Module by means of a shield connection clamp, e.g. Weidmüller
type KLBÜ 3-8 SC.
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 (4.33 in)
•
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 (4.33 in)
•
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 (100 hp) and
120 kW (150 hp) (the voltage for the fan unit is supplied by the
Active Line Module)
