Description
1.1 System overview
D4x5
10 Manual, 05/2009
● Compact machines
– Including the complete machine control in the drive
– With extensive connection possibilities for communication, HMI and I/O
● Distributed drive concepts
– Applications with many axes
– Synchronization of several SIMOTION D Control Units using distributed synchronous
operation
Versions
The individual versions - SIMOTION D425 (BASIC Performance), SIMOTION D435
(STANDARD Performance), and SIMOTION D445/D445-1 (HIGH Performance) - differ in
terms of their PLC performance and motion control performance. The main distinguishing
features are:
SIMOTION D425 SIMOTION D435 SIMOTION D445/D445-1
Maximum number of axes 16 32 64
Minimum servo/interpolator
cycle clock
2.0 ms 1.0 ms 0.5 ms
DRIVE-CLiQ interfaces 4 4 6
SIMOTION D4x5 features PLC and motion control performance (open-loop control and
motion control) for up to 16, 32 or 64 axes, as required.
Due to the following functional improvements, for new applications we recommend using
SIMOTION D445-1 (V4.1 SP2 or higher) instead of SIMOTION D445:
● an increase of around 30% in PLC and motion control performance, depending on the
application
● Less mounting depth (mounting is possible even without spacers)
● Double-fan/battery module for higher availability
● Further information (
http://support.automation.siemens.com/WW/view/en/31507782).
The computing functions integrated into the drive allow the D4x5 Control Unit to operate up
to six servo, four vector or eight V/f axes.
The drive control supports servo control (for maximum dynamic response), vector control (for
maximum torque accuracy) and V/f control.
Note
With the SIZER configuration tool, you can easily configure the SINAMICS S120 drive family
including SIMOTION.
It provides you with support for selecting and dimensioning the components required for a
Motion Control task.
You can also determine the possible number of axes and the resulting load with SIZER in
accordance with your performance requirements.
