SIMOCODE 3UF Motor Management and Control Devices
SIMOCODE pro 3UF7
motor management and control devices
■
Overview
SIMOCODE pro is a flexible, modular motor management sys-
tem for motors with constant speeds in the low-voltage perfor-
mance range. It optimizes the connection between I&C and
motor feeder, increases plant availability and allows significant
savings to be made for startup, operation and maintenance of a
system.
When SIMOCODE pro is installed in the low-voltage switchgear
cabinet, it is the intelligent interface between the higher-level
automation system and the motor feeder and includes the
following:
• Multifunctional, solid-state full motor protection which is
independent of the automation system
• Flexible software instead of hardware for the motor control
• Detailed operational, service and diagnostics data
• Open communication through PROFIBUS DP, the standard for
fieldbus systems
■
Design
General
SIMOCODE pro is a modularly constructed motor management
system which is subdivided into two device series with different
functional scopes:
• SIMOCODE pro C
• SIMOCODE pro V
Both series (systems) are made up of different hardware
components (modules):
System
Modules
SIMOCODE pro C
• Basic unit 1
• Current measuring module
SIMOCODE pro V
• Basic unit 2
• Current measuring module or
current/voltage measuring
voltage
• Operator panel (optional)
• Expansion modules
(optional)
• Operator panel (optional)
Per feeder each system always comprises one basic unit and
one separate current measuring module. The two modules are
connected together electrically through the system interface
with a connection cable and can be mounted mechanically
connected as a unit (one behind the other) or separately (side
by side). The motor current to be monitored is decisive only for
the choice of current measuring module.
An operator panel for mounting in the control cabinet door is
optionally connectable through a second system interface on
the basic unit. Both the current measurement module and the
operator panel are electrically supplied by the basic unit through
the connection cable. More inputs, outputs and functions can be
added to basic unit 2 (SIMOCODE pro V) by means of optional
expansion modules, thus supplementing the inputs and outputs
already existing on the basic unit.
All modules are connected together by connection cables.
The connection cables are available in various lengths. The
maximum distance between the modules (e.g. between the
basic unit and the current measurement module) must not
exceed 2 m. The total length of all the connection cables in a
single system must not be more than 3 m.
SIMOCODE pro designed for mixed operation
Depending on functional requirements, the two systems can be
used simultaneously without any problems and without any addi-
tional outlay in a low-voltage system. SIMOCODE pro C is fully
upward-compatible to SIMOCODE pro V. The same compo-
nents are used. The parameterization of SIMOCODE pro C can
be transferred without any problems. Both systems have the
same removable terminals and the same terminal designations.
