Zwick releases test software for Control Cube

A Zwick Roell product story
Edited by the Engineeringtalk editorial team Oct 7, 2009

Zwick, alongside partner company Cats3, has updated its suite of products relating to servo controllers and software for fatigue and durability testing in the automotive and aerospace sectors.

Building on installations of the Control Cube system, Zwick offers the Cubus software for the modular servo controller.

All data can be synchronised into a single integrated test using Control Cube and Signal Cube

Cubus software is an integrated package to configure and execute tests and includes various modules for cyclic tests, block programs and advanced ramp testing.

The external test module also provides access to existing modules in the Cats3 suite such as Qantim and Dura software for service load simulation and durability testing.

Control Cube offers several optional software plug-ins, each providing additional features to enhance its capabilities.

Typical examples of plug-ins are: integrated PID tuning facility, including auto-tune and adaptive tuning; a data module that includes acquisition, data export and data display; procedures and event-action matrix; virtual channels; and hydraulic grouping.

The controller's compact half 19in enclosure can be expanded with additional signal conditioning and then chained together to form up to 32 channels of control.

Differing user requirements have led to the development of the base software Cubuslight and a variety of Cubus test programs, as well as the optional plug-ins mentioned above.

Cubuslight comes as standard with the controller and provides test rig configuration; for example, transducer calibration, servo valve and control parameter settings.

It also provides execution of simple cyclic tests with various waveforms.

For more complex applications, various Cubus test programs are available, for example, the Cubus-Block program.

Using a graphical test editor, simple or complex tests comprising cyclic blocks, ramps, dwells and nested loops can be created.

Additional test programs include advanced ramp and external test.

An addition to the Control Cube range of products is the Signal Cube, which offers enhanced flexibility and connectivity for signal conditioning and integrated data acquisition for strain gauges or analogue inputs.

It offers up to six modular plug-in cards per Signal Cube chassis.

Each plug-in card provides four strain gauge channels 24-bit resolution at 4,096Hz maximum sample rate.

Signal Cube also features fully configurable 1/4, 1/2 or full bridge strain gauge conditioning and can integrate via CNet to Control Cube.

Zwick Roell will be exhibiting its latest products at Testxpo in Germany from 19 to 22 October 2009.
