A multi-axis drive consists of a Line Module, several Motor
Modules and a Control Unit. The Line Module generates a DC
voltage from the line voltage and supplies the Motor Modules
with energy via the DC link. In the Motor Modules, the DC link
voltage is converted by an inverter into an AC voltage for feeding
the motor. On the shared Control Unit, both the line infeed/
regenerative feedback and the closed-loop control of the motors
are computed. The connection between the Control Unit and the
power units is made very simply using the digital system inter-
face DRIVE-CLiQ.
SINAMICS S120 multi-axis drives are available with the cooling
methods internal air cooling and external air cooling and in the
following formats:
The SINAMICS S120 multi-axis drives are often used together
with a higher-level controller for motion control (SIMOTION,
SINUMERIK). For this reason, the following catalogs contain
a detailed description of SINAMICS S120 multi-axis drives
together with the perfectly matched servo, torque and linear
motors including the associated cables and connections and
the higher-level controllers for motion control:
