Active Line Modules
■
Overview
Active Line Module
Active Line Modules are self-commutated infeed/regenerative
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) supply systems.
The DC link is pre-charged by means of 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 electronic 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 connections
The status of the Active Line Modules is indicated via two
multi-color LEDs.
On the 100 mm (3.94 in) wide Active Line Module, the shield
for the power supply cable can be connected to the integrated
shield connection plate via a shield connection terminal or tube
clip, e.g., type KLBÜ CO 4 manufactured by Weidmüller. The
shield connection terminal must not be used as a strain relief
mechanism. Shield connection plates are available for 150 mm
(5.91 in, 200 mm (7.87 in) and 300 mm (11.81 in) modules.
The signal cable shield can be connected to the Line Module by
means of a shield connection terminal, e.g. type KLBÜ 3-8 SC
by Weidmüller.
The scope of supply of the Active Line Modules includes:
•
DRIVE-CLiQ cable for connection to the Control Unit on the
immediate left for drive control, length 0.11 m (4.33 in)
•
DRIVE-CLiQ cable (length depends on module width) to
connect Active Line Module to 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 and 120 kW
(the voltage 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:
•
CU320-2 Control Unit
•
SINUMERIK 840D sl with
- NCU 710.3B PN
- NCU 720.3B PN
- NCU 730.3B PN
- Numeric Control Extensions NX10.3/NX15.3
