Digital servo controller
Electro hydraulic servo dynamic-static fatigue testing machine LeadTestH digital dynamic servo controller
LeadTestH controller is a full-digital three-closed loop dynamic servo controller developed independently by AOWEI. It can adopt the most advanced international full closed loop control and data acquisition measurement and control technology, to realize precise control of force and motion. It is very convenient for perfect integration, configuration and application of AOWEI’s controller products and mature dynamic and static test application software. It can complete all kinds of tests. It is a reliable system for dynamic and static testing of materials and components. Its dynamic fatigue servo control technology represents the leading level inChina, and the technical performances of its products tend to be the world's top level.
LeadTestH controller using the computer PCI bus card management, can be placed in a multi system vertical control cabinet or directly installed on the test machine, and can also be used as a desktop independent system with configurable PC.
AOWEI’s application software matching with LeadTestH controller can run on the WINDOWS operating platform. Full digital closed loop speed regulating control system consists of the controller and the computer software and hardware. Various test parameters are controlled, measured, displayed, processed and printed by the computer. The integration is high, the use is convenient and reliable. It can be used for tensile, compression, fatigue (tension and compression) and various combinations of waveforms and other test. The system function is powerful, reliable and stable performance, easy to use.
AOWEI’s LeadTestH digital dynamic servo controller is a special one for full closed loop control and data acquisition of the material and product testing. It is a higher performance price ratio of high-end servo controller products.
LeadTestH controller adopts international advanced measurement and control technology -DSP and FPGA technology, with high speed dynamic data acquisition and real-time control operation function.
