Overview
20 kW, 40 kW and 100 kW Basic Line Modules in booksize format
Basic Line Modules are available 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 designed for connection to grounded,
star (TN, TT) and non-grounded, symmetrical IT supply systems.
The connected Motor Modules are pre-charged over the inte-
grated pre-charging resistors (20 kW and 40 kW) or through
activation of the thyristors (100 kW).
Basic Line Modules 20 kW and 40 kW are equipped with an
integrated brake chopper and can be used directly for
applications in generator mode after an external brake resistor
has been connected.
A Braking Module is only necessary in combination with the
Basic Line Module 100 kW in generator 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
(only 20 kW and 40 kW Basic Line Modules)
•
1 temperature sensor input
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
•
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
•
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
Note
:
The thermostatic switch built into the braking resistor must be
looped into the shutdown chain of the drive to prevent thermal
overloading of the system in the event of a fault. If a braking
resistor is not connected, a jumper must be connected between
X21.1 and X21.2.
■
Integration
The Basic Line Module receives its control information via
DRIVE-CLiQ from:
•
SINUMERIK 828D BASIC
•
SINUMERIK 828D
