Quantity structures
With SIMOTION D, the SIMOTION PLC and motion control functionalities as well as the
SINAMICS S 120 drive software run on a shared control hardware. The IEC 61131‑3-compliant
PLC integrated in SIMOTION D means that the system is not just capable of controlling
sequences of motions, but the entire machine as well.
● The scaling of the PLC and motion control functionality is performed via Control Units of
various performance classes for SIMOTION D
– SIMOTION D410-2 is predestined for single-axis solutions and small multi-axis solutions
with typically 2-3 axes (max. 8 axes)
– SIMOTION D425-2 (BASIC performance) for up to 16 axes
– SIMOTION D435-2 (STANDARD performance) for up to 32 axes
– SIMOTION D445‑2 (HIGH performance) for up to 64 axes
– SIMOTION D455‑2 DP/PN (ULTRA‑HIGH performance) for up to 128 axes or
applications with very short control cycle clocks
The possible axis quantity structures depend on the required servo and interpolator cycle
clocks and apply for electric, hydraulic and virtual axes.
● The scaling of the drive computing performance is performed via SINAMICS drive controls
for the SIMOTION D4x5‑2. With the SIMOTION D4x5‑2, the drive control of a CU320‑2 is
already integrated (SINAMICS Integrated). It can be extended as follows:
– SINAMICS S110/S120 Control Units can be connected via PROFIBUS or PROFINET
– The CX32-2 Controller Extension can be connected via DRIVE‑CLiQ
SIZER
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.
● Dimensioning of the PLC and motion control functionality --> selection of the SIMOTION D
Control Unit
● Dimensioning of the drive computing performance and the required drive components.
Depending on your performance requirements, SIZER determines the possible number of axes
and the resulting utilization on the SIMOTION and SINAMICS side.
Drive quantity structure
The following table can be used for a rough estimation of the maximum possible quantity
structures on the drive side.
Depending on the functionality used, more or less performance resources are used on the
drive control.
The performance points specified in the table can be used for a rough estimation. Maximum
15.5 performance points are available for each drive control (SINAMICS Integrated, CX32‑2,
CU320‑2).
