The benefits for you

The stepper motor module is perfect for incorporating into the existing MOVI-PLC® I/O system. It can therefore be added to other I/Os and/or the bus coupler by means of a profile rail.

Different modules can be used on one bus coupler, e.g. up to 27 stepper motor modules on the backplane bus.

The MOVIKIT® Custom stepper software module (included in the scope of supply) based on standard IEC 61131-3 makes integration and startup both simple and fast.

Everything from a single source
Our fully comprehensive automation portfolio means customers need only one contact person for the complete drive and automation technology.

The straightforward format adjustment and other implemented control modes can execute even servo-similar applications cost-efficiently.

The properties of a stepper motor enable integration without a gear unit, saving installation space.

Resource-friendly format and product changes can be completed quickly.

The continuous rise in product diversity and the increasing demand for individuality in the market environment, combined with the general trend toward batch size 1, mean that ever more frequent changes of formats and products are needed in machinery. Our format-changing drive system has been designed with precisely this in mind. It consists of a stepper motor terminal (stepper motor module), actuator and encoder cables, and a stepper motor. In terms of software, the system is supported and incorporated by the MOVIKIT® Custom stepper software module based on standard IEC61131-3. Besides facilitating extremely straightforward format adjustments, different control modes make it possible to implement control tasks with load fluctuations and torque-controlled applications in a cost-effective way.

In more and more areas of application, the preferred option is to use electromagnetic drives rather than conventional pneumatic cylinders. There are various reasons for this. The poor efficiency of pneumatic solutions, the high costs associated with startup, changeovers, service, and maintenance, and the limited controllability of these systems all play a key role.

A recent total cost comparison has shown that, in terms of component and electricity prices, electromagnetic drives can pay for themselves within just a few months, even in the case of simple point-to-point movements with two end positions. They also make a valuable contribution to reducing the carbon footprint. What's more, electromagnetic drives offer greater flexibility when it comes to designing production processes and production monitoring systems. Their controllability allows for optimized process management and gives rise to new opportunities for more efficient production processes.

All in all, these advantages clearly demonstrate that electromagnetic drives constitute an attractive alternative to conventional pneumatic systems. Electromagnetic drives help industry act more sustainably, from both an economic and an ecological perspective:

Software module

A prefabricated stepper software module based on standard IEC 61131-3 makes it easier to integrate the format-changing drive system into your application.


  • Communication
    The OCE12C bus coupler connects the MOVI-PLC® I/O system to the controller via EtherCAT®.
  • Compatibility
    Other I/O modules, such as safe or non-safe function modules, can be operated using the same coupler.
  • I/Os
    The three DIs (digital inputs) directly on the stepper motor module can be used to incorporate components such as limit switches for referencing purposes.
  • Software
    In terms of software, the system is integrated using a MOVIKIT® Custom stepper software module (included in the scope of supply) based on standard IEC61131-3.
  • DC-24-V/DC-48-V operation
    The DC-24-V or DC-48-V supply is fed directly into the stepper motor module.
