Description
1.1 System overview
SIMOTION D4x5
12 Manual, 02/2012
Application
SIMOTION D4x5 is ideally suited to applications with many coordinated axes with high clock-
pulse rates.
Typical applications include:
● Compact multiple-axis machines
● High-performance applications with short machine cycles
● 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, we recommend using a SIMOTION D445-1
instead of a SIMOTION D445 for new applications as of V4.1 SP2:
● 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.
