Ensure seamless, effortless coordination of multiple axes and drives

As an operator of complex systems, you need to ensure that different motion sequences, multiple axes, and various drives are precisely coordinated with one another. The efficiency of your production depends on this. In order to ensure this required intelligent coordination, you also need both intelligent and reliable control technology.

The control cards from our controller hardware portfolio have been precisely tailored to meet this requirement. Control cabinet installation units are used wherever users are required to implement centrally processed applications.

Thanks to their simple operation and multitude of ready-to-use function modules, they ensure the efficient implementation of motion functions. Their real potential comes to the fore when movements are permitted across multiple axes and need to be coordinated precisely. If the different motion axes within a system are connected via a rapid, synchronous system bus, the recommendation would be to control all motion control tasks via a single controller. SEW-EURODRIVE's control technology is ideally equipped for this too. Depending on the performance class, their controllers can handle up to 64 axes using an SBus or SBUSPLUS (system bus with onboard EtherCAT interface). The integrated system bus also allows connection to any of the inverter types in their portfolio.

You can also benefit from the outstanding performance features of SEW-EURODRIVE's control technology and implement functional and cost-efficient automation for your systems and machines.

You can choose from three different performance levels, each providing optimum control of all motion sequences, depending on your machine and automation requirements:

  •    -   DHx21B standard performance class for use as a module controller with motion control functions such as positioning, average response times, and a maximum of 16 axes.
  •    -   DHx41B advanced performance class for use as a module controller with high-end, motion-control functions such as electronic gear units, electronic cams and robotics, short response times, and a maximum of 16 axes.
  •    -   UHX71B power performance class for use as a module controller or controller for complete automation for demanding motion-control and automation tasks, response times in the 1-millisecond range, and a maximum of 64 axes. The controller can be extended by a second Windows 7 Embedded operating system.

MC What to Consider When Choosing a New Motion Control Solution 1 400x275

When it’s time to consider a new motion control solution for your application, rule #1 is “Solve the problem, then worry about the design.”

This is easier said than done, but not if you apply a disciplined, time-tested framework. First, you must clearly understand the problem and the local environment. Failure to do so often results in a suboptimal motion control solution or complete failure.

Secondly, the designer should evaluate the application in light of proven existing motion control solutions. The engineer must also take stock of their skills and the expertise of the team in order to effectively choose the right options and to accurately anticipate development time and resources.

Before choosing any motion control products, the design engineer needs a set of principles to guide his or her selection. Long term experience and common sense has taught us seven important, but often overlooked, principles. 

These key learning have been encapsulated in a simple notion known as the SHAIRED paradigm:

  • •Simplicity of design to reduce problem-causing complexity and cost
  • Homework; calculate the required torque, inertia, duty cycle, etc.
  • Analysis of the application and alternatives must be thorough
  • Integration of the system into existing factory automation
  • Redundancy built in to a system to exceed performance expectations and deal with unexpected changed in load and operating parameters
  • Economical solution for the short and long term.
  • Development time must be accurately estimated

Using the above guidelines during motion control system design, evaluation of alternatives, and final product selection will help increase the odds of application success.
