Basic functionality

The SIMOTION D basic functionality is supplied with the CompactFlash card (CF) and is loaded when the power is switched on. The basic functionality includes:

• SIMOTION runtime system
  • User-programmable with several languages conforming to IEC 61131
  • Various runtime levels
    (cyclic, sequential, event-driven)
  • PLC and arithmetic functionality
  • Communication and management functions
  • Motion Control functions (Motion Control Basic)
• SINAMICS S120 drive control
  • SIMOTION D410?2:
    Current/speed control
    (based on CU310?2, firmware version V4.x) for up to 1 servo axis, 1 vector axis or 1 V/f axis
  • SIMOTION D4x5?2:
    Current/speed control
    (based on CU320?2, firmware version V4.x) for up to 6 servo axes, 6 vector axes or 12 V/f axes, closed-loop control for infeed (Active Line Module)
• Testing and diagnostic tools

This basic functionality can be expanded with loadable technology packages, if required.

Position-controlled motion control for drives

• Integrated drives (SINAMICS Integrated):
  The power units are connected over DRIVE-CLiQ or over the integrated PM-IF interface optionally for the SIMOTION D410-2.
• Drives with digital setpoint interface:
  SIMOTION D enables position-controlled motion control for drives with digital setpoint interfaces via PROFINET IO/PROFIBUS DP with PROFIdrive.
• Drives with analog setpoint interface, e.g. for retrofit or hydraulic applications:
  The ADI 4 (Analog Drive Interface for 4 Axes) or IM 174 (Interface Module for 4 Axes) module can be used to connect drives with analog ±10 V setpoint interfaces. The IM 174 also makes it possible to connect stepper drives with a pulse direction interface.
  Both modules are connected over PROFIBUS DP. The following can be connected to one ADI 4 or IM 174 module:
  • 4 drives
  • 4 encoders
  • Digital inputs and outputs

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 ?s 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 requirements 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 the 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 outputs on the 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.

Safety Integrated functions via PROFIsafe

Safety Integrated functions are activated via "PROFINET with PROFIsafe" or "PROFIBUS with PROFIsafe" safe communication. The control (F logic) is implemented using an F-CPU connected via PROFINET or PROFIBUS. The connection for configuring the system with SCOUT TIA can only be made via PROFINET.

Safety Integrated functions are routed through from the SIMOTION D410?2 and D4x5?2 Control Units to the following drives:

• Integrated SINAMICS S120 drives on SIMOTION D410?2 and D4x5?2
• Drives on the SIMOTION CX32?2 Controller Extension
• Drives on SINAMICS Control Units connected via PROFIBUS to SIMOTION D.
• Drives on SINAMICS Control Units connected to SIMOTION D via PROFINET (F?CPU must be connected via PROFINET in this case).
