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 with the SINAMICS CUA
adapter. 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. DRIVE-CLiQ can be used to link encoder
systems and special DRIVE-CLiQ I/O devices in addition to power components.
Software components: SIMOTION runtime system and SINAMICS closed-loop drive control
The basic functionality of SIMOTION D is supplied on a Compact Flash card containing the
following:
SIMOTION runtime system including the following functions:
• User-programmable runtime system (IEC 61131)
• Various runtime levels
• PLC and arithmetic functionality
• Motion control functions
• Communication functions
SINAMICS S120 drive control including the following functions:
• Closed-loop current and torque control
• Closed-loop speed control
• Closed-loop infeed
