DQ420MA 39/42 miniature stepper motor driver

2. Parameter description:
?1) This model can only be equipped with two-phase stepping motor of 39,42,57 series below 1.7A rated current!
2) According to the usage of most customers, the positive poles of all signal terminals are combined into a +5V terminal, so this driver can only be controlled by common anode, only the NPN active low PLC can be connected :)


DQ420MA two-phase hybrid stepping motor driver

I. Overview

DQ420MA subdivision two-phase hybrid stepping motor driver is powered by DC 12~36V. It is suitable for two-phase hybrid stepping motor with driving voltage of 24V~36V and current less than 2.0A outer diameter of 42~57mm. The driver is subdivided with an all-digital current loop. The torque ripple of the motor is small, the running at low speed is stable, and the vibration and noise are low. It can output relatively high torque at high speed and has high positioning accuracy. It is widely used in equipments with high resolution requirements such as engraving machines, CNC machine tools, packaging machinery, and transmission equipment.
