The servo motor driver has low cost and excellent performance, so it is the mainstream low-power motion controller. It has reached or even surpassed the AC servo system in terms of accuracy, noise, speed and low speed stability, and is widely used in industries such as spray painting, small and medium-sized engraving, electronic processing, digital control machine tools, packaging equipment, textile printing, etc. The effect is particularly good when it is used in equipment with minimal vibration, ultra-low noise and high speed that users expect.
