Overview
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 are designed for connection to grounded
TN/TT and non-grounded IT supply systems.
The Basic Line Modules are available in different frame sizes.
With frame sizes FB and GB, a fully controlled thyristor bridge
is used to pre-charge the Basic Line Modules and connected
Motor Modules. The thyristors normally operate with a trigger
delay angle of 0°.
Basic Line Modules, frame size GD for 900 kW (400 V) or
1500 kW (690 V) include a diode bridge, and the DC link is
pre-charged via a separate line-side pre-charging circuit.
A Braking Module of the appropriate frame size can be integrated
into a Basic Line Module in order to permit, in conjunction with an
external braking resistor, regenerative operation of the drive
system.
■
Design
The Basic Line Modules have the following interfaces as
standard:
•
1 line supply connection
•
1 connection for the 24 V DC electronics power supply
•
1 DC link connection (DCP, DCN) for supplying the connected
Motor Modules
•
1 DC link connection (DCPA, DCNA) for connecting a
Braking Module
•
3 DRIVE-CLiQ sockets
•
1 temperature sensor input for KTY84-130, Pt1000 or PTC
(Pt1000 can be used from firmware V4.7 HF17)
•
1 PE connection
The status of the Basic Line Modules is indicated via three LEDs.
The scope of supply of the Basic Line Modules includes:
•
DRIVE-CLiQ cable to connect to a Control Unit
•
DRIVE-CLiQ cable to connect the Control Unit to the first
Motor Module
•
1 set of warning labels in 30 languages
(BG, CN, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HU, IE, IS, IT,
JP, KR, LT, LV, MT, NL, NO, PL, PT, RO, RU, SE, SI, SK, TR)
Pre-charging circuit for the Basic Line Modules,
frame size GD
Unlike Basic Line Modules in frame sizes FB and GB, a Basic
Line Module in frame size GD requires a separate precharging
circuit. The pre-charging circuit components must be ordered
separately.
During startup, the pre-charging circuit ensures that the DC link
capacitors of the Basic Line Module and the connected
Motor Modules are pre-charged with current limiting. After pre-
charging has been completed, the circuit breaker is closed and
the pre-charging circuit bypassed; the Basic Line Module is then
directly connected to the line supply.
The pre-charging circuit comprises a pre-charging contactor
and pre-charging resistors; the circuit must be protected against
overcurrent using suitable protection measures. To increase the
permissible DC link capacitance, the pre-charging resistors can
also be connected in parallel in each phase.
More information on the pre-charging circuit is to be found in the
SINAMICS Low Voltage Engineering Manual.
