VS-I electro-hydraulic hybrid system of special synchronous servo drive is synchronous servo drive with high performance, high reliability and high response.
The product is based on high performance digital signal processor DSP based on the flexible digital control module, the control arithmetic and the software of the servo motor, to achieve the high performance vector control, accurate position and speed control, speed control and nonlinear weak magnetic location correction vector speed control.
At the same time in order to meet the requirements of high speed and high precision servo control, built-in auto-disturbance-rejection control and speed control algorithm for observation, with the compensation of servo feed forward control, command smoothing technique, dynamic tracking performance and steady state has better, realize servo high response, high precision and high reliability. According to the characteristics of injection molding machine, full decoupling PQ control algorithm, enhanced the response speed of injection molding machine, smooth movement speed and pressure control conversion.
