Description
1.1 System overview
SIMOTION D4x5
14 Manual, 02/2012
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 PM340 power modules 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,
encoder systems and special DRIVE-CLiQ I/O devices can also be linked via
DRIVE-CLiQ.
Extension of the drive computing performance
The motion control performance of a SIMOTION D4x5 can be utilized in full by expanding
the computing performance at the drive in two different ways:
● SINAMICS S110/S120 Control Units complete with further SINAMICS S110/120 drive
modules can be connected via PROFIBUS or PROFINET.
● With SIMOTION D435 and D445/D445-1, the CX32 controller extension can be
connected via DRIVE-CLiQ. This module is extremely compact and can control up to
six servo, four vector or eight
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:
● User-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:
● Current and torque control
● Speed control
● Closed-loop infeed
