SIEMENS Easy Motion Control – Software for SIMATIC Controllers

SIEMENS Easy Motion Control

Easy Motion Control is the flexible and low-cost softwarebased solution for position-controlled tasks with SIMATIC controllers. Easy Motion Control is comprised of function blocks for the controller and parameterization software.

Overview

  • Low-priced package for simple, controlled positioning and simple geared synchronous motion
  • For use with any standard variable-speed drive, such as frequency converter or servo drive
  • For incremental and absolute encoders
Application

Easy Motion Control is a low-cost package for simple, controlled positioning and simple geared synchronous motion of several axes. It is suitable for use with any standard variable-speed drive, such as frequency converter or servo drive

Incremental and absolute encoders are supported.

Possible applications include, for example:

  • Single operating axes,
  • Positioning/setup axes
  • Palletizers,
  • Feeder units or
  • Material transport
Design

Easy Motion Control comprises:

  • Configuration and commissioning user interfaces for STEP 7
  • Function blocks for controlled positioning and geared synchronous motion.
  • Drivers for SIMATIC modules:
    The actual position value is input and the setpoint speed is output via modules from the standard SIMATIC range. Matching driver blocks are included with the most common modules. Additional modules can be linked by means of an open driver (see technical specifications).
  • Drivers for DP coupling to MM4.
  • Configuration software for parameter assignment and commissioning:
    The handling of the configuration software is supported by an online help.
  • Sample programs for various applications to make it easier to get started.
Licensing

The function blocks of Easy Motion Control require one runtime license for each CPU onto which they are loaded.

The engineering interface for STEP 7 up to V5.5 is included in Easy Motion Control V2.1 and can be installed without license.

Packaging
  • Easy Motion Control V2.x with software and documentation,
    comprising

    • a CD with the software for STEP 7 up to V5.5 and
    • a CoL for one runtime license.
  • Easy Motion Control without software and documentation, comprising
    • a CoL for one runtime license (valid for V2.x and V11 or higher)
Function

Easy Motion Control offers the following basic functions for positioning:

  • Move absolute:
    The axis moves to the specified position. With rotary axes, the target can be approached in a positive or negative direction or on the shortest possible path.
  • Move relative:
    The axis moves by the specified distance in a positive or negative direction.
  • Reference point approach, reference setting:
    Synchronizes the measuring system with the mechanical system.
  • Gearing:
    Axis moves to a different axis in gearing.
  • Jog:
    The axis moves for as long as the control bit for one direction is present.
  • Stop:
    Stops the motion and brings the axis to a standstill.
  • Simulation:
    A program can be tested in the simulation even if a real axis is not present and no actual values can be read in.
