SIMOTION technology packages
A special feature of SIMOTION is that the basic functionality can
be expanded by loading technology packages, such as:
•
Motion Control with the technology functions:
- POS – Positioning
- GEAR – Synchronous operation/electronic gear
- CAM – Cam
- PATH - Path interpolation
•
TControl – Temperature controller
•
MIIF – Multipurpose Information Interface
•
Vibration Extinction (VIBX)
• OACAMGEN
Since the technology functions have modular licenses, you only
pay for what you will actually use.
Performance
Hardware-supported floating-point arithmetic enables complex
arithmetic functions to be used effectively.
Fast instruction execution opens up completely new application
possibilities in the mid-performance to high-performance range.
Configuring/parameterizing/programming
SIMOTION SCOUT is a powerful and user-friendly engineering
tool. It is an integrated system for all engineering steps, from
configuring and parameterization, through programming, to
testing and diagnostics. Graphical operator prompting, using
dialog boxes and wizards, as well as text-based and graphical
languages for programming, considerably reduce the
familiarization and training periods.
Operator control and monitoring (HMI)
Communication services which support user-friendly data
exchange with SIMATIC HMI devices are integrated in the basic
functionality of SIMOTION D.
These HMI devices can be connected to SIMOTION D over
PROFINET, Industrial Ethernet or PROFIBUS and they are
configured using SIMATIC WinCC (TIA Portal).
Version V7.0 and higher of the SCADA system SIMATIC WinCC
features a SIMOTION channel which is included as standard on
the WinCC DVD.
With the SIMATIC NET communications software, an open,
standardized OPC interface is available for accessing
SIMOTION from other Windows-based HMI systems.
SIMOTION IT service and diagnostic functions
SIMOTION IT provides SIMOTION D with an integrated web
server on which, for example, user-specific web pages can be
stored.
Read and write access can be made to the Control Unit
variables. Java scripts or applets also allow the implementation
of active operation and display functions in the web pages that
can be executed on a client PC with an Internet browser.
Process and data communication
Thanks to its integrated interfaces, SIMOTION D supports both
process and data communication.
PROFINET IO with IRT is available for exacting Motion Control
applications. In addition to cycle clock synchronization, cycle
times of minimum 125 μs and safety-related communication
(PROFIsafe), the PROFINET interfaces on the SIMOTION
D4xx-2 Control Units also support media redundancy
(MRP/MRPD).
The SIMOTION SCOUT engineering system is provided for user-
friendly communication configuration and diagnostics.
Safety Integrated functions
Highly effective protection of personnel and machinery can be
implemented with SIMOTION D thanks to the integrated safety
functions of SINAMICS S120.
The integrated safety functions that are currently available are
described below. Their functional safety satisfies the require-
ments defined in the international standard IEC
61800-5-2
for
variable-speed drive systems.
The safety functions integrated into the SINAMICS S120 drive
system can be roughly divided into four categories:
•
Functions for safely stopping a drive
- Safe Torque Off (STO)
- Safe Stop1 (SS1)
- Safe Stop2 (SS2)
- Safe Operating Stop (SOS)
•
Functions for safe brake management
- Safe Brake Control (SBC)
- Safe Brake Test (SBT)
(this diagnostic function exceeds the scope of IEC 61800-5-2)
•
Functions for safely monitoring the motion of a drive
- Safely Limited Speed (SLS)
- Safe Speed Monitor (SSM)
- Safe Direction (SDI)
•
Functions for safely monitoring the position of a drive
- Safely Limited Position (SLP)
- Safe Position (SP)
(this function exceeds the scope of IEC 61800-5-2)
Activation of Safety Integrated functions
Safety Integrated functions can be activated by the following
methods:
•
Via terminals on SIMOTION D4x5-2/CX32-2 and on the power
unit (STO, SBC, SS1 only)
•
Via fail-safe inputs on the TM54F Terminal Module
•
Via fail-safe inputs on SIMOTION D410-2
•
Via PROFINET/PROFIBUS with PROFIsafe.
The SLS and SDI functions can also be activated permanently
via parameter assignment.
The Safety Integrated functions are implemented electronically
and therefore offer short response times in comparison to
solutions with externally implemented monitoring functions.
