XICONTROL COMPRISES THE FOLLOWING FUNCTIONS:

  • Integration of hardware components (linear actuators, sensors, other testing appliances)
  • Scaling of individual input signals
  • Multivariable closed-loop control system with preset parameters
  • Optional tuning of control parameters for special applications
  • Definition of virtual projects to implement different test rig setups
  • Sequencer to define additive test program design concepts
  • Acquisition, preprocessing, and export of measured data
  • Secure interfaces for customized functionalities

YOUR BENEFITS WITH XICONTROLS

With many established competitors in the market, we have listened closely to the needs of our longtime customers. XiControl is therefore specifically designed for small and medium sized testing applications with little complexity and low dynamics. It fi ts seamlessly into the MOCOKIT system and can also be used to upgrade existing test rigs, regardless of brand. Despite the wide range of functions, the system off ers only those features needed for cost-effective yet accurate testing. With CFM specializing in customized test rig engineering, we integrate many optional functionalities upon request.

ADVANTAGES OF XICONTROL

  • High-quality development, implementation, and components Made in Germany
  • Cost-effective complete system to match your needs
  • Maximum compatibility through harmonized software and hardware
  • Faultless communication with unified software architecture
  • Precise metrology and robust actuator controls
  • Modular extension of additional hardware into the software
  • Perfect integration into new and existing MOCOKIT test rigs

FIELDS OF APPLICATION

XiMotion is an industry-neutral testing software ideally suited for research and development as well as quality assurance purposes. Common applications are tensile and rigidity tests in materials research or fatigue testing of components in automotive, aviation, and agricultural industries. The system can however be used in almost any field with the following requirements.

  • Uniaxial testing; multiaxial applications optional
  • Dynamics: static, pulsating, and low dynamics up to 3 Hz
  • Loadings: tensile and compressive between 10 and 100 kN
  • Actuators: strokes between 100 and 250 mm
  • Customized solutions with different properties possible

LINEAR TESTING ACTUATORS

XiControl is specifi cally developed for testing applications with electromechanical actuators. When testing in a medium force range with low dynamic properties, this type of actuator has many advantages over classic hydraulic actuators. There is no need for hydraulic media supply, which signifi cantly reduces operating costs and additionally keeps your test rig clean. The components weigh less and can be handled manually, they take up less space in the test rig setup, and the lack of hydraulic hoses causes less interference. CFM XiControl with electromechanical
actuators provides high thrusts and speed with a high control precision.

505+/- 50 / 75 /10050/100
8010+/- 50 / 75 /10050/100
10025+/- 50 / 75 /10050/100
10050+/- 100 / 15050/100
125100+/- 100 / 15025/50/100
Industry Example: Customized seat test rig
Industry Example: Fatigue testing with MOCOKIT ®

If our standard actuator specifi cations do not meet your requirements, please feel free to contact us for an individual offer. We do provide actuators with different specifi cations, from other suppliers, with special functionalities like water-resistance, or alternative systems with hydraulic or pneumatic actuators.

TESTING SOFTWARE SUIT

XiMotion is an industry-neutral testing software suited for research and development as well as quality assurance purposes. XiMotion seamlessly integrates with the various CFM hardware components for testing as well as existing test rigs of other manufacturers.

The user-friendly PC program allows management of entire testing workfl ows. Features include actuator and sensor integration, adjustable actuator controls, synchronization of external components with I/O interfaces, definition of customized test sequences, signal processing, measurement data recording and analysis, automated reporting, and optional actuation of PLC-controlled hardware.

TECHNICAL DATA CFM CONTROLLER

  • Sampling rate: 1-10 kHz,
  • Standard I/Os: Position and force; 8 digital I/Os
  • Optional I/Os: up to 32 analog I/Os allow flexibility in extension and synchronization
  • Resolution of measured values: 64 bit
  • Resolution of A/D conversion: 24 bit
  • The closed-loop control system features position and force control as well as a multivariable
    combination of control modes. Preset control properties can be tuned for special applications

SOFTWARE PACKAGE

Our user-friendly XiMotion software allows managing of all relevant aspects in your testing process. The intuitive GUI provides every function in one program. Creating test signals in the so called sequencer is realized with graphical function blocks, requiring no knowledge of programming languages and consist of an additive test program design concept. One or multiple signals can be displayed in online graphs in order to enhance live analyses and optimizations. Limit values can be set to key parameters of the hardware in order to protect operators and the test rig components.

Multiple Add Ons (see picture below) are available to create an individual solution for your testing process and requirements.

SEQUENCER

The test sequences are generated in XiMotion by configuration and combination of various test step elements. Simple and complex actuation signals are possible for diff erent control modes. Complex waveforms include sinusoidal, trapezoidal, triangle, and rectangle signals with optional frequency and amplitude sweeps. Nested loop structures as well as case diff erentiation based on external signals can be implemented. Diff erent limit functions allow restriction and surveillance of values. Measurement data recording is adjustable in terms of recording rate, variable selection, recording intervals, and punctual sampling. The standard analysis tools are extendable with customer-specific evaluation algorithms. Open-format report templates allow easy (re)confi guration in an automated reporting process.
