Specification parameters
    LEESN DM420 two-phase pulse stepper driver is a new generation of high-performance two-phase digital stepper driver based on 32-bit DSP technology. The drive voltage is DC8V-48V, the adaptive current is below 2.2A, and the outside diameter is below 42.

    The driver sampling similar to the servo control principle, unique circuit design, superior software algorithm processing, so that the motor can run smoothly even under low subdivision, almost no vibration and noise, smooth and accurate current control technology greatly reduces the motor heat, external 16 speed equal Angle constant torque subdivision, up to 128 subdivision, optocoupling-isolated differential signal input, Strong anti-interference ability, with over-voltage, under-voltage, over-current protection and other error protection functions. Subdivision, current, logic power parity parameters can be set through the upper computer. In the field of medium and low speed application such as patch machine and laser engraving, its stability, vibration and noise performance advantages are obvious, which can greatly improve the performance of the equipment.
