Overview
Basic Line Modules in booksize format
Basic Line Modules are used for applications in which no energy
is returned to the supply or where the energy exchange between
motor and generator axes takes place in the DC link. Basic Line
Modules can only feed energy from the supply system into the
DC link, energy cannot be fed back into the supply system. The
DC link voltage is directly derived from the 3-phase line voltage
via a 6-pulse bridge circuit. Basic Line Modules are suitable for
connection to grounded, star TN, TT and non-grounded sym-
metrical IT supply systems. The connected Motor Modules are
pre-charged over the integrated pre-charging resistors (20 kW
and 40 kW) or through activation of the thyristors (100 kW).
The 20 kW and 40 kW Basic Line Modules are equipped with an
integrated brake chopper and can be directly used for applica-
tions in generating mode after connecting an external braking
resistor.
A Braking Module is only required with a 100 kW Basic Line
Module in generating mode.

Design
The Basic Line Modules in booksize format feature the following
connections and interfaces as standard:
•
1 power connection
•
1 connection for the 24 V DC electronics power supply
•
1 DC link connection
•
3 DRIVE-CLiQ sockets
•
1 connection for braking resistor
(20 kW (25 hp) and 40 kW (50 hp) Basic Line Modules only)
•
1 temperature sensor input for KTY84-130, Pt1000 or PTC
(Pt1000 can be used from firmware V4.7 HF17)
The status of the Basic Line Modules is indicated via two
multi-color LEDs.
The scope of supply of the Basic 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 Basic Line Module
width) for connection to the adjacent Motor Module,
length = width of Basic Line Module + 0.11 m (4.33 in)
•
Jumper for connecting the 24 V DC busbar to the adjacent
Motor Module
•
24 V terminal adapter (X24)
•
Connector X21
•
2 blanking plugs for sealing unused DRIVE-CLiQ sockets
•
1 set of warning labels in 30 languages
