Introduction
SINUMERIK 840D sl – open, flexible, powerful
Perfect drive solutions for equipping machine tools
SINAMICS S120 Combi
combines the performance capability
of the modular SINAMICS S120 with a rugged, compact size. An
infeed and up to 4 Motor Modules are integrated into a single en-
closure. The intelligent expansion by 2 Motor Modules has made
the SINAMICS S120 Combi the perfect basis for equipping com-
pact, standardized machine concepts with a spindle power of
up to 15 kW and up to 5 feed axes.
SINAMICS S120
is synonymous with performance capability
and flexibility in the equipment of machine tools. Not only a wide
range of Motor Modules with up to 300 kW power but also an in-
feed with a closed-loop DC link are available. This provides the
shortest spindle acceleration times, and enables perfect reac-
tive current compensation of the entire machine (cos
ϕ
= 1). Fur-
thermore, Dynamic Servo Control (DSC) offers a unique closed-
loop position control process for the highest dynamic response
of feed and spindle motors.
All components of SINAMICS S120 and S120 Combi, including
the SIMOTICS motors and encoders, are connected to the
SINUMERIK 840D sl via the high-speed
DRIVE-CLiQ
interface.
In this way, the CNC control detects the electronic rating plates –
that is the relevant performance data and production data – of
all the connected components. This ensures not only automated
commissioning, but also optimal diagnostics, faster service and
efficient maintenance.
