Distributed Drive Technology
7.1 SIEMOSYN 1FU8 motors with integrated frequency converter
SIEMOSYN motors with integrated frequency converter result in a variable-speed
drive with sophisticated closed-loop control characteristics.
Neither an external frequency converter nor cabinet is required.
A SIEMOSYN 1FU8 motor and the MICROMASTER 411 frequency converter are
mechanically coupled with one another.
The two physically and spatially separate components – the motor at the driven
machine, the frequency converter in the electrical cabinet – are fused to become a
compact single unit.
Advantages
In addition to the well-known advantages SIEMOSYN 1FU8 motors, other advantages
come into play.
Versatile and communication-capable frequency converter electronics which can
be connected to bus systems play an important role – within the scope of the automation
solution – to minimize energy costs.
Significant time and cost saving with respect to conventional solutions:
� The electrical cabinet is not required (the frequency converter is mounted on the
motor)
� Lower installation and mounting time and costs. The motor and frequency converter
are shipped assembled which means that wiring between the two components
is not required
� Lower emission (EMC) thanks to the extremely short cables;
The motor – frequency converter connection is within the enclosure.
This means that there are no problems associated with cable lengths and frequency
converter output components are eliminated (those components associated
with long cable lengths)
� Engineering time and costs are eliminated at the motor/frequency converter
units are optimally matched to the customers requirements. They are shipped
as a complete pre-assembled drive unit.
� The control is relieved as the frequency converter has its own integrated monitoring
functions
