Control technology “made by SEW‑EURODRIVE”

Solve many of your automation tasks flexibly and effectively using control technology from SEW‑EURODRIVE. This page gives you a brief overview of the universal and scalable controller and software program that can be easily integrated into various automation concepts in an effective and economical manner. It is not relevant whether the movement requires free programming or whether it can be implemented by a standardized application module.

The concept:

SEW‑EURODRIVE offers the freely programmable motion and logic controller MOVI‑PLC® for solving complex tasks in a flexible manner®. The scalable controllers are the ideal solution platform as they make for universal operation and functionality. Comprehensive interfaces are available for the external periphery and for visualization to fully automate complete machines.

For fast and simple startup, users can utilize preconfigured program modules for many applications. The standard programming languages FBD, LD, IL, and structured text ensure great flexibility.

MOVI-PLC®® always provides the drive functionality matching the specific application. It can be used whenever intelligent drive solutions are required, for example, when a number of drives has to perfectly interact. MOVI‑PLC® controls this interaction in a simple and flexible manner® .

The various fields of application and mounting positions of the MOVI-PLC®® offer the perfect control topology for any requirement: motion control either modular with an I/O system or as stand-alone component.

Motion control
With simple operation and a variety of preset function blocks, the controllers allow for the efficient implementation of motion functions, particularly when several axes are to be coordinated. Since the axes are connected to a fast synchronous system bus, all the motion control tasks can be taken over by one controller.
In practice it is favorable in many cases that I/Os, which directly depend on the motion sequence or have an effect on them, are processed in the controller, for example in the form of cam switches or touch probe events. In addition to motion control, the controller then controls individual sequences of sub-processes and automates a self-sufficient module of a machine. Benefits: Less workload for the PLC, reduced response times, and increased performance. Further, integrating functionality in the controller can protect the company's know-how and reduce the workload when changing the central automation system.
Moreover, in conjunction with the Drive Operator Panels (DOP) and the I/O system, all the components required for an automation solution are provided – a drive with suitable drive electronics, a control with a flexible I/O system, as well as visualization. The stand-alone controller takes over all the automation tasks ranging from motion control to sequence control.

Motion control with MOVI-PLC®® offers three options that will provide functional solutions quickly and easily for every application, irrespective of the complexity of the task or the programming skills of the user.

MOVI-PLC® Control Technology
Function blocks: Versatile combinations and flexible use
Direct access to blocks that allow for a certain drive function provide the highest level of flexibility. The function blocks are clearly arranged in libraries according to their functions and inverter type. With some experience, users can flexibly combine these function blocks to create the optimum program.

Program modules: Optimally combined for efficient use
The program modules comprise bundled comprehensive drive functions. These can be simple functions such as positioning, referencing or speed control, technology functions for controlling a cam or synchronous operation, or functions for multi-axis interpolations of kinematics. Once these program modules have been integrated, the user merely has to concentrate on programming the most important processes for their application. The program modules conveniently provide the entire drive functionality via one interface. This makes the program modules ideal for PLC programmers who want to reduce the programming effort of the drive functionality.
MOVI-PLC® Control Technology
In addition to a library for standard IEC functions, the MOVI-PLC®® provides a library with function blocks with suitable drive functions for each type of inverter to allow for efficient programming. They comprise the following functions: Enabling the drive, presetting the speed, positioning, referencing, as well as reading or writing parameters.
In addition, there are libraries for technology functions such as synchronous operation, cam, virtual master axis and cam control. These function modules can be combined easily to create individual, tailor-made solutions.
