product manual:

 DOLI's fatigue testing machine full digital control system EDC580 is the latest generation product with excellent functions and superior cost performance; they are a dedicated electronic system for full closed loop control and data acquisition of material and structure testing machines. The new EDC control system replaces the original EDC60 With EDC120, there are all-round enhancements in hardware and system software, but at the same time it maintains compatibility with previous products. EDC580 focuses on applications ranging from complex static tests to conventional dynamic tests of one to twenty Hz up to 250 Hz.

Main technical indicators of EDC580 fatigue testing machine:

Control unit: It can realize the closed-loop control function, and can perform all-digital PID control on any collected signal. The closed-loop control frequency: 5kHz;

Servo valve drive unit: secondary servo valve drive control;

Frequency range: 0.001-1000 Hz, frequency resolution: 0.001 Hz;

Control waveform: sine wave, triangle wave, square wave, ramp wave, etc.;

Control mode: PID closed-loop control of force, displacement and deformation, which can realize smooth and undisturbed switching of any control mode;

Application areas:

1. Testing machine industry: dynamic testing machine and static testing machine;

2. Research institutes and universities: self-made test equipment;

3. Mechanics laboratory: transformation and upgrading of existing test equipment
