Servo Controller for Fatigue and Endurance System

Next Generation of Superb User Friendly Multi-Function Controller Drastically enhances the accuracy of endurance and dynamic testing on materials and actual specimens The 4830 Controller serves as a multi-function, superb user friendly controller for servo-controlled materials testing machines. This controller offers all the functions and performances needed for the control and measurements in the testing of static and dynamic characteristics of materials, actual objects, or structures. The 4830 Controller incorporates full digital control of all elements, including waveform generation, automatic...

Load waveform generation with excellent reproducibility Full digital controller with control parameter functions like autotuning and waveform distortion correction (note *1) to achieves true load waveform reproduction. Synchronous testing with up to four testing machines Synchronous connection of controllers permit testing with up to four actuators. The phase correction function incorporated in the controller allows constant control of the phase difference between the feedback signals. Test force control for specimens with “free play” characteristics. Achieves stable peak-value test force control...

Drastically Enhances Load-waveform Reproducibility Autotuning Automatically determines the control parameters, which were previously based on operator’s experience and pre-testing every time there is changed in specimen or test conditions. Before autotuning After autotuning Response waveform Setting signal Response waveform Setting signal Waveform Distortion Correction* This function uses FFT to correct the amplitude and phase frequency components to achieve true load waveform reproduction when the waveform becomes distorted due to the specimen properties or time variations. Graph before correction...

Synchronous Testing with up to Four Testing Machines Synchronous Testing Simultaneously connection of controllers permit synchronous control and measurements with up to four actuators. Each actuator phase can be set as required. Multiple Tests Simultaneous up to 4 Tests Up to four tests, each with different test conditions, can be conducted simultaneously using a single PC. For example, collect peak values and cycle data from four endurance tests running in parallel. (Requires optional Windows software.) Compatibility Connection to an actuator system or any series of testing machine. Force Simulator...

User Friendly Functions From Test Setup to Completion Test Setup When mounting a specimen, the jog dial controls the piston with the function of analog operation. The touch-load function* prevents overloading of the specimen during mounting. * This function monitors test loads to prevent overloading. Setting Test Conditions Interactive touchpanel operation simplified test conditions settings The test-condition registration functions allow tests to be conducted with preset test conditions. User friendly interactive settings Simply select a file to display the easy to read test-condition listings....

Numeric display Testing Numeric values or waveform can be displayed during test. Waveform display allows observation of the specimen condition during test as time graph, X-Y graph, or peak graph. Time graphs Waveform display Peak graphs Test Completion The test completes upon achieving the preset limit condition such as achieving excessive measured value or the number of cycles. The stop mode function is selectable for power unit stop, waveform stop, waveform zero, displacement hold, unload, or manifold off during test completion. These stop modes protects the specimen during test completion.

The dedicated software for the Servo Controller 4830 consists of basic software, add-on testing software, and GLUON 4830 fracture toughness testing software. *Windows software is optional Add-On Software Note: Requires basic software Basic Software The clear and user-friendly interface makes software operation easy. Programmable Waveforms (Program Function Testing) Combination of ramp, sine and other waveforms with testing based on waveform data such as actual waves further extends the range of test applications.

Endurance and Static-characteristics Testings Apart from the controller, the software permits independent or continuous testing. Continuous testing is with the combination of endurance and static-characteristics testing. Endurance testing Static-characteristics testing Combination testing Setting made easy with wizard Even beginners or novices can easily and accurately set the test conditions by following the Test Condition Wizard procedures. Mail notification The mail notification function reduces the daily monitoring workload. It sends email at pre-determined intervals during testing or when...
