The XT690 series servo driver takes the latest digital processing chip (DSP) from the American TI Company as the core control, adopts advanced all-digital motor control algorithms, and fully realizes the closed-loop servo control of current loop, speed loop and pressure loop in a software way. It has good energy-saving performance and self-adaptive ability, and can be matched with Xingtai motors and various specifications of servo motors. It is suitable for application systems that require rapid response for precise speed control and positioning control, especially in plastic machinery, etc.
