SINAMICS S120 Cabinet Modules
■
Overview
In the SINAMICS S120 Cabinet Modules, the built-in units of the
SINAMICS S120 chassis format are integrated to provide a
modular cabinet system for multi-motor drives with a central line
infeed and a common DC link busbar for crane systems. As
standard, they are installed side by side in a row.
The main components of the system in crane applications are as
follows:
•
Line Connection Modules with line-side components such as
contactors, fuses and circuit breakers
•
Line Modules for infeed in the Active Line Module version for
four-quadrant mode with negligible line harmonic distortion
and integrated line contactors
•
Motor Modules in chassis format for controlling motors
•
Switch-Over Modules for both economic and redundant
combinations of motors and Motor Modules
•
Motor Multi Connection Modules for parallel connection of
motors for gantry drives in particular
•
Motor Double Choke Modules for connecting a reactor bet-
ween Motor Modules and motors when long cables are used,
as is the case in gantry drives
The industry-specific version Cranes ordering option
B70
is
based on the requirements of the EN 60204-32 standard and
implements the measures required for the cabinet units.
Specification in contrast to the available standard cabinet
design:
•
All auxiliary power supplies are routed to terminals for wiring
in star topology
•
Vibrational load in operation
- Deflection 1.0 mm at 2 to 13.2 Hz
- Acceleration 6.8 m/s² at 13.2 to 100 Hz
•
The colors of the cores are in accordance with
DIN EN 60204-32 except in the case of built-in
Chassis Modules
•
The complete documentation is supplied for the cabinets for
the ordered configuration
•
Internal wiring of the transport units
•
Prepared wiring for easy assembly

When used in cranes, the industry-specific option
B70
must be specified separately on ordering for all cabinets.
