Description
2.1 System overview
A SIMOTION D axis grouping generally consists of the following elements:
● SIMOTION D (Control Unit) (1)
● One SINAMICS infeed (Line Module) (2)
● SINAMICS power units (Motor Modules) (3)
● DRIVE-CLiQ components (4)
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.) complete
● With SIMOTION D4x5‑2, the CX32-2 controller extension can be connected via
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

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.
This module generates a DC link from the supply system.
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.
In SINAMICS S120 / SIMOTION D, the individual components of the drive system
communicate with each other via DRIVE‑CLiQ. In addition to power components, encoder
systems and special DRIVE‑CLiQ I/O devices can also be linked via DRIVE‑CLiQ.
with further drive components can be connected via PROFIBUS or PROFINET.
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.
