DE2608C closed-loop stepper driver

DE series pulse stepper closed-loop driver

Product Introduction

DE2608C is a new type of stepper closed-loop driver successfully developed according to market demand and development trends. It adopts a new 32-bit motor control dedicated DSP chip and pure servo principle control technology, making the motor run more smoothly and less prone to losing steps. By outputting signals and alarm signals to the outside, the controller can monitor the real-time operation status of the motor, significantly improving the high-speed performance of the motor, and successfully minimizing the heating degree and vibration amplitude of the motor, thereby better improving the machining speed and accuracy of mechanical operation. The working voltage of the driver is AC18V-80V/DC36-110V, suitable for various models of two-phase stepper motors with an outer diameter of 57-86mm and a current below 6.0A.
