Description
1.1 System overview
Hardware components
As the central hardware, SIMOTION D uses the SIMOTION D4x5-2 as control unit consisting
of the SIMOTION runtime system and the SINAMICS drive control. The control unit uses the
SINAMICS Integrated drive with various SINAMICS S120 drive modules (line and motor
modules) to perform open-loop and closed-loop control of the axis grouping. A range of
additional SINAMICS S120 components, such as SMx encoder systems or terminal modules
can also be connected via DRIVE-CLiQ. With a few exceptions (e.g. no basic positioner
EPOS, no basic operator panel BOP20, etc.), the drive control integrated in SIMOTION D
has the same control characteristics and performance features as the SINAMICS S120
CU320-2 control unit. The EPOS functionality is provided by the SIMOTION technology
functions. The functionality of SIMOTION D can be expanded with the distributed I/O via
PROFIBUS or PROFINET IO.
The following figure shows a typical SIMOTION D axis grouping.
Figure 1-1
A SIMOTION D axis grouping generally consists of the following elements:
● SIMOTION D (control unit) (1)
● One SINAMICS infeed (line module) (2)

Example of an axis grouping with SIMOTION D4x5-2
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.
