Motion Control Chart (MCC)
Motion Control Chart (MCC) is a "flow diagram language" that
can be used to graphically formulate the process procedures in
machines or cranes in a simple manner. The result is one or more
flow diagrams, comprising MCC blocks that describe the time
sequence of the individual function module. Due to its special
means of expression, MCC (Motion Control Chart) is ideally
suited to programming sequential processes.
Various MCC blocks are available for controlling the machine,
for example, conditions must be fulfilled, I/O signals can be
read or set, calculations can be formulated and different control
structures such as condition (IF), cases (CASE) and loops
(WHILE, REPEAT UNTIL) can be programmed.
All MCC blocks – a selection of the most important SIMOTION
functions – are available in toolbars, see figure below.
In SIMOCRANE Basic Technology, MCC is implemented for
the sequence control of every function module (e. g. hoist).
This results in a clear flow chart for the drive-based control.

Optional Drive Control Chart (DCC) packages
The Drive Control Chart (DCC) option packages for SIMOTION
and SINAMICS extend the possibilities for easy graphical con-
figuration of technology functions using pre-defined function
blocks.
Multi-instance capable function blocks are selected from a pre-
defined library and graphically interconnected using drag and
drop. The standard function block library comprises a large
number of closed-loop control, arithmetic and logic blocks as
well as extensive open and closed-loop control functions.
In the Crane DCC Library, individual crane-specific technolo-
gies (e.g. load-dependent field weakening) can be pre-config-
ured using the SIMOTION standard DCC Library and encapsu-
lated in individual macro modules. These Crane DCC blocks are
used for setpoint conditioning (velocity, acceleration) of the
function module (e. g. hoist) at the time-cycle level. In this man-
ner, transparent closed-loop control related structures are shown
and previously created blocks can be reused many times.
