A SIMOTION D axis grouping generally consists of the following elements:
● SIMOTION D (Control Unit) (1)
This unit contains the programmable runtime system of SIMOTION and the drive software
of SINAMICS S120. In principle, SIMOTION D is capable of controlling multiple axes/drives.
● One SINAMICS infeed (Line Module) (2)
This module generates a DC link from the supply system.
● SINAMICS power units (Motor Modules) (3)
These modules are used to control motors.
It is also possible to operate SINAMICS Power Modules in blocksize format with the
SINAMICS Control Unit Adapter (CUA). A separate infeed is then unnecessary.
● DRIVE-CLiQ components (4)
In SINAMICS S120 / SIMOTION D, the individual components of the drive system
communicate with each other via DRIVE‑CLiQ. In addition to power components, it is also
possible to link encoder systems and special DRIVE‑CLiQ I/O devices via DRIVE‑CLiQ.
Extension of the drive computing performance
The motion control performance of a SIMOTION D4x5‑2 can be utilized in full by expanding
the computing performance at the drive in two different ways:
● SINAMICS S/G Control Units (e.g. CU320‑2, CU310‑2, CU305, CU250S‑2, etc.) together
with further drive components can be connected via PROFIBUS or PROFINET.
● With SIMOTION D4x5‑2, the CX32-2 Controller Extension can be connected via
DRIVE‑CLiQ. This module is extremely compact, does not require a separate
CompactFlash card and can control up to 6 servo, 6 vector or 12
V/f axes.
Software components
The basic functionality of SIMOTION D is supplied on a CompactFlash card containing the
following:
The SIMOTION runtime system with the following functions:
● Freely programmable runtime system (IEC 61131)
● Various runtime levels (tasks)
● PLC and arithmetic functionality
● Motion control functions
● Communication functions
The SINAMICS S120 drive control with the following functions:
● Closed-loop current and torque control
● Closed-loop speed control
● Closed-loop infeed
